Is CertainTeed Really the Best Vinyl Siding? A Contractor's Perspective After 20+ Years
CertainTeed is widely considered one of the premier names in vinyl siding, and its reputation has been built over decades. But what actually makes CertainTeed better than other manufacturers? Are its products truly superior, or are many of the advantages simply the result of good marketing, brand recognition, and a long history in the building materials industry?
I've been in the exterior remodeling business for more than 20 years, and during that time I've worked with siding from several manufacturers, including CertainTeed, Mastic (Ply Gem), and Norandex. At JP Construction Services, we primarily offer CertainTeed siding, and it's a brand I have a great deal of confidence in. But I'm also realistic about the industry. Many vinyl siding products are remarkably similar, and some of the features manufacturers promote as major innovations are available from their competitors as well.
So why do I prefer CertainTeed? I think the answer has less to do with any single feature and more to do with the complete package: product selection, panel design, color options, engineering, specialty products, and the company's long-established reputation. Some of those advantages are more meaningful than others, and a few are worth examining more closely.
CertainTeed's Product Selection Is One of Its Greatest Strengths
One area where CertainTeed really stands out is the variety of siding products it offers. Homeowners can choose from economical traditional vinyl siding, premium horizontal profiles, longer panels, vertical board and batten, insulated siding, reinforced products, and realistic shake and shingle designs. Many manufacturers offer several of these options, but CertainTeed brings an especially broad selection together under one brand.
Its traditional horizontal vinyl siding lineup includes Encore, MainStreet, American Legend, Restoration Classic, Monogram, and Carolina Beaded. These products range from approximately .040-inch entry-level panels to premium .046-inch siding, with different profiles, textures, and color selections. CertainTeed also offers Monogram XL in extended lengths and CERTAplank, a foam-reinforced product with a wide, flat 7-inch profile.
The selection becomes even more extensive when you include CedarBoards insulated siding, Cedar Impressions polymer shakes and shingles, Northwoods vinyl shakes, and CertainTeed's vertical siding products. This allows us to design a home's exterior using combinations of traditional horizontal siding, board and batten, shake accents, contrasting colors, and coordinating accessories without necessarily having to switch manufacturers.

I've written a separate comparison of CertainTeed's horizontal siding lines, including their thicknesses, profiles, color selections, and relative costs. Homeowners can also use our Online Siding Estimate Calculator to compare available products and see how different selections affect the actual price of replacing their siding.
Monogram XL: Why 25-Foot Siding Panels Can Make a Huge Difference
One of my favorite CertainTeed products is Monogram XL, and I think its longer panel lengths are a much bigger advantage than many homeowners realize. Traditional vinyl siding generally comes in panels approximately 12 feet long. Whenever a wall is longer than the panel, the installer needs to overlap the ends of adjoining pieces, creating visible seams. These overlaps are perfectly normal, but they can become noticeable, particularly on long walls, darker siding colors, or when sunlight hits the house from certain angles.
CertainTeed Monogram XL offers panels in lengths up to 25 feet, depending on the profile and availability. Think about what that means for the appearance of your home. On a wall that's 20 or 24 feet wide, a single panel may be able to span the entire distance without an overlap seam, provided the necessary expansion clearances are maintained. With traditional 12-foot panels, the same wall would require multiple pieces and at least one visible overlap on every course of siding.
And we're not talking about eliminating just one seam. Because horizontal siding is installed in rows from the bottom of the wall to the top, that same overlap can appear repeatedly across dozens of courses. Using 25-foot panels could eliminate every overlap seam on an entire wall, potentially removing dozens of visible seams from that one elevation alone.
Even on longer walls, the difference can be substantial. Consider a 35-foot-wide wall. Using standard 12-foot panels would generally require three pieces per course, creating two overlaps. Using 25-foot panels could reduce that to just two pieces and one overlap. Across 20 courses of siding, that's 20 fewer seams on a single wall.

Now consider a typical house with multiple elevations, gables, garage walls, and other exterior surfaces. On many homes, 25-foot panels could eliminate all overlap seams on several walls and substantially reduce the total number throughout the entire house. Windows, doors, and other openings can also break up siding runs, sometimes allowing installers to eliminate overlaps in areas that would otherwise require them.
The result can be a noticeably cleaner, more continuous appearance that more closely resembles traditional wood siding. There are some trade-offs, of course. Longer panels are more difficult to transport and handle, and installers must pay particular attention to expansion and contraction. CertainTeed has specific center-pinning instructions for its 25-foot panels. But when appearance is a priority, I think Monogram XL is one of the most worthwhile upgrades available in conventional vinyl siding.
I've written extensively about how to minimize, hide, or eliminate vinyl siding seams, including how overlap direction, seam staggering, and panel placement can affect the finished appearance. Even when using standard-length siding, good planning makes a difference. But using panels long enough to eliminate the overlaps altogether is obviously an even better solution when the house allows it.
Other manufacturers offer extended-length siding, so CertainTeed isn't alone in recognizing the benefit. But having a 25-foot option available is a genuine advantage, especially for larger homes with long, uninterrupted walls. If you're wondering whether the upgrade is worth the additional cost, our Online Siding Calculator lets you compare available siding grades and explore your options.
Why I Prefer CertainTeed's Traditional 4-Inch Siding Profiles
One of the things I've always preferred about CertainTeed is something that probably wouldn't stand out to most homeowners looking at siding samples: the actual size and shape of the horizontal siding profiles. Mastic's traditional horizontal siding offerings commonly include 4½-inch and 5½-inch exposures, while CertainTeed offers true 4-inch profiles in products such as MainStreet and Monogram. That half-inch difference might not sound like much, but when you're looking at an entire house covered in siding, it changes the overall appearance more than you might expect.

I particularly notice the difference with Dutchlap siding. Mastic's Dutchlap profile has a bevel that sits lower on the panel, while CertainTeed's traditional 4-inch Dutchlap has a higher bevel that creates a tighter, cleaner appearance. I've always preferred the way the CertainTeed profile looks once it's installed. The narrower exposure creates more horizontal lines across the wall, and to my eye, those tighter lines give the house a more refined, traditional appearance.
There's also a practical consideration. All else being equal, a narrower siding profile generally has less unsupported surface area between its bends and locking points, which can contribute to greater rigidity. That doesn't automatically mean every 4-inch CertainTeed panel is stronger than every 4½-inch or 5½-inch Mastic panel, because thickness, shape, and reinforcement also matter. But I do see the smaller profile as an advantage in both appearance and panel design.
This is admittedly a personal preference, and some homeowners may prefer the wider exposures. But having installed and worked with both products, I give CertainTeed the edge when it comes to traditional horizontal siding profiles, particularly the 4-inch Dutchlap. It's a relatively small difference on paper that I think becomes much more noticeable when you see the finished house.
For examples of these profiles and a closer look at the differences, see our article about CertainTeed Monogram siding and whether its additional thickness is worth the upgrade.
CertainTeed's Fully Insulated Siding: CedarBoards
CertainTeed also manufactures fully insulated vinyl siding under its CedarBoards product family. Unlike traditional hollow-backed vinyl siding, CedarBoards uses contoured foam insulation attached to the back of the panel. This provides additional rigidity while also increasing the thermal resistance of the wall assembly. Depending on the product and installation, insulated siding can also help reduce some exterior noise and improve the finished appearance by providing more support behind the vinyl.

The CedarBoards family includes traditional horizontal profiles such as Double 4-inch clapboard, Double 4½-inch Dutchlap, Double 6-inch clapboard, and Single 7-inch clapboard, subject to current product availability. CertainTeed has also offered CedarBoards XL with extended-length insulated panels, including 16-foot-8-inch options. This combines the benefits of foam-backed siding with fewer visible overlap seams.
Another interesting option is CedarBoards Insulated Board & Batten, which offers a vertical profile with a wide 10-inch board and 2-inch batten. This creates a more substantial board-and-batten appearance while providing the additional support and thermal benefits of foam insulation. It can be an attractive choice for homeowners who want vertical siding on an entire house or as an accent on gables and other architectural features.
I do think insulated siding has legitimate benefits, but I wouldn't automatically assume that it will produce dramatic energy savings. The actual improvement depends on the insulation already inside the walls, the condition of the house, air leakage, and the R-value of the specific product. Mastic Structure, ProVia CedarMAX, Alside Prodigy, and other insulated siding products offer similar benefits, so the comparison should be based on the actual specifications rather than the manufacturer alone.
There's also another way to improve insulation when replacing siding: installing a separate insulation product beneath traditional vinyl siding. We've compared Low-E Housewrap and traditional 3/8-inch foam insulation in a separate article, including how the products work and what homeowners should consider when choosing between them.
CERTAplank: A Different Kind of Foam-Backed Siding
CERTAplank is one of the CertainTeed products I find most interesting because it takes a different approach to foam-backed vinyl siding. Most traditional insulated siding uses relatively thick contoured foam primarily to increase the insulation value of the exterior wall. CERTAplank uses a thinner layer of foam reinforcement, with the primary benefits being rigidity, panel support, and appearance rather than a substantial increase in R-value.
The product features a .046-inch vinyl face and a wide, flat Single 7-inch profile that looks considerably different from conventional hollow-backed vinyl siding. The foam reinforcement helps support the panel across its width, producing a flatter, more substantial appearance that resembles traditional wood lap siding. It also works with standard siding accessories, which can make it easier to incorporate into conventional siding installations without the deeper trim details often associated with thick insulated siding.
This is where CertainTeed may have a particularly interesting advantage. Other manufacturers certainly make foam-backed siding, but most of the major competing products are marketed as insulated siding systems, with thicker foam and thermal performance as primary selling points. I haven't identified a directly comparable product from another major manufacturer that combines CERTAplank's relatively thin reinforcement, wide flat 7-inch profile, and conventional accessory compatibility.

That doesn't mean CERTAplank is necessarily stronger or better than every other premium siding product. But it offers a different appearance and construction than conventional vinyl siding, and I think it's an excellent option for homeowners who want something closer to the appearance of wood or fiber cement without the maintenance requirements of those materials.
We have a dedicated article taking a closer look at CertainTeed CERTAplank siding, including its construction, appearance, colors, and potential advantages. It's worth exploring if you're considering a premium alternative to conventional hollow-backed vinyl siding.
CertainTeed Board & Batten and Vertical Siding
Board and batten siding has become increasingly popular, especially on modern farmhouse-style homes and as an accent on gables, dormers, and entryways. CertainTeed offers several versions of vertical siding, giving homeowners a choice between conventional vinyl, insulated siding, and foam-reinforced products. These options can produce noticeably different appearances, even though they're all commonly described as board and batten.
CertainTeed's traditional Single 7-inch Board & Batten has a nominal thickness of .052 inches, making it one of the thicker conventional vinyl siding products in its lineup. Its Single 8-inch Board & Batten offers a wider profile with a nominal thickness of approximately .048 inches. Both create the familiar vertical appearance of alternating boards and raised battens.
For homeowners who want insulation, CedarBoards Insulated Board & Batten provides a wider 12-inch profile with foam backing. CertainTeed also offers Reverse Board & Batten Reinforced Siding, a Single 7-inch product that uses thin foam reinforcement and a reversed profile to create a different architectural appearance. Like CERTAplank, the reinforced design focuses heavily on rigidity and the appearance of the finished panel.
One of the things I like about CertainTeed's vertical siding selection is how easily these products can be incorporated into a larger exterior design. A homeowner might choose Monogram horizontal siding for most of the house, board and batten for the front gables, and Cedar Impressions shakes for an entryway or dormer. These combinations can dramatically change the appearance of a home without requiring an entirely different type of exterior cladding.
We've explored some of these possibilities in our article about creative ways to use vertical or shake vinyl siding as an accent feature. Our Online Siding Calculator also allows homeowners to explore available accent options and see how their selections affect the total project price.
Cedar Impressions and Northwoods: Shake and Shingle Siding
CertainTeed also offers an extensive selection of shake and shingle-style siding designed to reproduce the appearance of natural cedar. Its Cedar Impressions line uses molded polymer panels to create realistic wood textures, including straight-edge, staggered, and specialty shake and shingle profiles. These products can provide the character of cedar without the regular painting, staining, or maintenance associated with natural wood siding.
Northwoods is another CertainTeed product family offering vinyl shake and shingle appearances, including rough-split and perfection-style designs. These products can be used across an entire house, but I particularly like them as accent features on gables, dormers, and other architectural areas. A relatively small amount of shake siding can make a substantial difference in a home's appearance, especially when paired with traditional horizontal siding.
Other manufacturers offer attractive shake and shingle products, too, so CertainTeed doesn't have this category to itself. But the variety of profiles, textures, and coordinating colors is another reason I appreciate its overall lineup. Homeowners have considerable flexibility to create a custom exterior appearance while staying within the CertainTeed family.

Does CertainTeed Really Offer Better Siding Colors?
CertainTeed has an extensive color selection, and it's something the company understandably promotes. But having worked with several manufacturers, I don't necessarily consider color variety a major advantage for CertainTeed. Mastic and Norandex also offer attractive colors across their primary siding lines, and there's a considerable amount of overlap between the manufacturers when it comes to the shades most homeowners choose.
If you showed the average homeowner the available colors from CertainTeed MainStreet or Monogram, Mastic Ovation or Quest, or Norandex Woodsman Select and its other traditional siding offerings, I suspect most people would find several colors they'd be perfectly happy with. The manufacturers may use different names for their colors, and the shades won't be identical, but their core selections are generally quite similar. Most homeowners aren't choosing between manufacturers because one offers a good beige, gray, white, or blue and the others don't.
Where differences become more important is when someone wants a very specific color. Maybe it's a particular shade of green, an unusually dark charcoal, or a deeper blue that one manufacturer offers and another doesn't. In those situations, I don't see any reason to rule out a different reputable manufacturer just because CertainTeed is our usual preference. If another company makes the exact color a homeowner wants in a comparable quality product, switching manufacturers may make perfect sense.
CertainTeed's PermaCOLOR technology is also a legitimate feature, but other manufacturers have their own color-retention technologies and substantial fade warranties. I wouldn't assume that CertainTeed's colors are automatically going to last longer without comparing the specific products and warranty terms. A lifetime limited fade warranty also doesn't mean the siding is guaranteed never to change color, since these warranties define acceptable color changes and contain specific limitations.
My opinion is that CertainTeed offers an excellent color selection, but so do its major competitors. Its real advantage is the combination of those colors with its extensive range of profiles, specialty products, and panel lengths—not necessarily the number of colors alone.

Homeowners can explore our CertainTeed MainStreet siding color gallery, see roofing and siding color combinations, or look at some dark siding and black exterior trim ideas. We've also discussed how to choose the color of your new roof or siding, including whether to focus on resale value or simply choose what you like best.
Does CertainTeed Make Thicker or Stronger Vinyl Siding?
Siding thickness is one of the easiest specifications to compare because it's an actual measurement rather than a marketing claim. CertainTeed offers products ranging from approximately .040 inches for Encore to .046 inches for Monogram, with some specialty vertical products exceeding .050 inches. Generally speaking, thicker vinyl siding provides additional rigidity and may help conceal minor imperfections in a wall, although its overall performance depends on more than thickness alone.
But .046-inch siding is .046-inch siding, regardless of which manufacturer makes it. Mastic, Norandex, and other companies offer products with comparable thicknesses, and some competing products are thicker than certain CertainTeed lines. That doesn't automatically make them better, just as the CertainTeed name doesn't automatically make a panel stronger.
The overall design of the panel also matters. Its shape, depth, locking mechanism, reinforced nail hem, and method of fastening can all affect how the siding performs. That's why comparing products based on thickness alone doesn't tell the whole story, although I do believe thickness is one of the more meaningful specifications homeowners should consider.
I've discussed these factors in more detail in CertainTeed Monogram Siding: Is the Extra Thickness Worth It?, including the differences between Monogram and more economical siding options.
RigidForm: CertainTeed's Reinforced Nailing Flange
CertainTeed uses its RigidForm technology on selected siding products, including Monogram. This system incorporates a reinforced, rolled-over nail hem designed to add rigidity to the upper portion of the panel and improve resistance to wind loads. It's a legitimate engineering feature, and one I appreciate because the nailing flange is an important part of the siding panel that homeowners never see once the installation is complete.

But CertainTeed isn't alone in offering reinforced nailing systems. Other manufacturers have developed their own reinforced hems and specialized panel designs intended to improve wind resistance and overall rigidity. The important comparison is how the complete siding assembly performs under testing, rather than whether one manufacturer has a more recognizable name for its technology.
And regardless of the product, proper installation is critical. Vinyl siding must be fastened securely while still allowing for expansion and contraction as temperatures change. Nailing siding too tightly can cause buckling or distortion, even when the product has a reinforced nail hem. I consider RigidForm a positive feature, but it doesn't replace the need for experienced installers.
STUDfinder: A Useful Installation Feature
CertainTeed also offers its STUDfinder installation system, which uses markings along the nailing flange to help installers locate framing members. The markings can simplify fastening on walls with conventional stud spacing, and the system is incorporated into certain longer panels as well. It's a thoughtful feature that demonstrates the company's attention to installation details.
That said, experienced siding installers already have methods for locating studs, and not every wall has framing positioned exactly where the markings suggest. The system can be helpful, but I wouldn't consider it a major reason for a homeowner to choose CertainTeed over another manufacturer. It's one of several small features that contribute to the overall product rather than something that fundamentally changes the performance of the siding.
CertiLock and DuraLock: How Important Are the Locking Systems?
CertainTeed uses engineered locking systems, including CertiLock and DuraLock, on various siding products. These systems are designed to help adjoining panels engage securely, maintain proper alignment, and resist wind forces. A well-designed locking mechanism is important because the siding panels need to remain connected while still allowing for normal thermal movement.

But other manufacturers have their own locking technologies, including Mastic's T3-LOK system on certain products. I haven't seen convincing independent evidence demonstrating that CertainTeed's locking systems are universally superior to those offered by every competing premium manufacturer. As with the nail hem, I think the overall tested performance of the panel and the quality of installation are more important than the trademarked name of the locking mechanism.
CertainTeed's History and Reputation as a Company
CertainTeed was founded in 1904 and has been manufacturing vinyl siding for decades. Today, it's part of Saint-Gobain, one of the world's largest building materials companies. CertainTeed also has an established presence in residential roofing, insulation, and other building products, giving it a level of name recognition and industry experience that many smaller manufacturers don't have.
I think that matters, particularly when we're installing a product that homeowners expect to last for decades. A manufacturer's history, product support, distribution network, and ability to stand behind its warranties are all worth considering. A lifetime limited warranty is only as valuable as the coverage it provides and the company's ability to honor it.
Of course, being a large company doesn't automatically mean every product is superior, and CertainTeed has had its share of product changes and business decisions over the years. But I do place value on working with an established manufacturer that has been a major part of the residential building materials industry for generations.
Is CertainTeed Actually Better Than Mastic or Norandex?
Having worked with CertainTeed, Mastic, and Norandex siding, I don't think it's fair to say that every CertainTeed product is better than every competing product. Both Mastic and Norandex have offered quality vinyl siding, and many of their products share similar specifications and features with CertainTeed. A premium product from one of those manufacturers may be a better choice than an entry-level CertainTeed product, depending on the application.
That's why I believe homeowners should compare actual product lines instead of relying entirely on brand names. Comparing CertainTeed Monogram to another manufacturer's premium siding makes sense. Comparing Monogram to an inexpensive builder-grade product and then declaring CertainTeed the better manufacturer doesn't tell us very much.
Where CertainTeed wins me over is the complete product selection, the availability of specialty profiles, the extended panel lengths, and the company's established reputation. I also personally prefer the tighter appearance of its traditional 4-inch horizontal siding, particularly the Dutchlap profile. I don't necessarily believe its vinyl formulation is dramatically better than everyone else's, or that every trademarked feature provides a substantial advantage. But when I look at the entire lineup, I think CertainTeed offers one of the strongest combinations of quality, appearance, and versatility in the industry.
The Quality of the Installation May Matter More Than the Manufacturer
One thing I always want homeowners to understand is that even the most expensive siding can perform poorly when it's installed incorrectly. Improper fastening, inadequate flashing, incorrect clearances, poor water management, and failure to allow for expansion and contraction can create problems that have little to do with the siding manufacturer. Some of those problems may not become apparent until years after the installation.
On the other hand, a properly installed midgrade siding product from a reputable manufacturer can provide excellent performance for decades. That's why I believe homeowners should spend as much time evaluating the contractor installing their siding as they do comparing the products themselves. The best siding in the world isn't going to compensate for poor workmanship.
I've also written about the ideal siding replacement project if it were my own house, including the siding, insulation, trim, colors, and installation details I would personally choose. It gives homeowners a better understanding of the decisions that matter beyond simply choosing a manufacturer.
Why We Primarily Install CertainTeed Siding
After more than 20 years in exterior remodeling, I believe CertainTeed offers one of the best overall vinyl siding product lineups available. Not because every competing manufacturer makes an inferior product, but because CertainTeed provides an excellent combination of traditional siding, premium profiles, longer panels, insulated products, reinforced siding, architectural accents, and extensive color options.

I particularly appreciate the 25-foot Monogram XL panels, which can eliminate dozens of visible overlap seams and give a home a much cleaner appearance. I also prefer the tighter lines of CertainTeed's traditional 4-inch siding, especially its Dutchlap profile. CERTAplank is another product I find interesting because of its thin foam reinforcement and wide, flat profile, while CedarBoards provides fully insulated options for homeowners who want additional thermal performance.
CertainTeed's PermaCOLOR, RigidForm, STUDfinder, and locking systems are all worthwhile features, even though other manufacturers offer similar technologies. For me, the real advantage is having all of these products and options available from a company with such an established reputation.
We primarily install CertainTeed because we trust its products, appreciate the selection, and believe they offer excellent value to our customers. Not because we think every other siding manufacturer makes an inferior product.
