When it comes to protecting your home, a quality asphalt architectural roofing system is one of the most important investments you can make. This type of roofing not only enhances the look of your home but also provides long-lasting protection against the elements.
At JP Construction Services, we ensure that every roof installation includes all the essential components for maximum durability and performance. Here’s a breakdown of what makes up a proper asphalt roofing system.
Underlayment
The underlayment is a water-resistant or waterproof barrier that sits between your roof deck and the shingles. It provides an extra layer of protection against water infiltration from wind-driven rain or ice dams. Typically made of felt or synthetic material, the underlayment plays a critical role in preventing moisture damage to your home’s structure.
Starter Shingles
Starter shingles are the first row of shingles installed at the eaves of your roof. They’re designed to provide a secure base for the first course of shingles and to help seal the edge against wind uplift. Without starter shingles, your roof repair or installation may be vulnerable to water intrusion and shingle blow-off.
Ice and Water Shield
This waterproof membrane is typically installed along the eaves, valleys, and roof penetrations. It protects areas most vulnerable to water infiltration caused by ice dams or heavy rain. Using ice and water shield is essential in cold climates and is a best practice for any asphalt shingle roofing system.
Flashing
Flashing is used to direct water away from critical areas of the roof. There are several types of flashing used in residential roofing:
Valley flashing: Installed in the valleys where two roof slopes meet.
Step flashing: Used along roof-to-wall intersections.
Skylight flashing: Surrounds skylights to prevent leaks.
Apron flashing: Placed at the base of walls or dormers.
Chimney flashing: Seals the gap between the chimney and roof.
Pipe flashing: Seals around plumbing vents or other penetrations.
Each type of flashing ensures that water is properly diverted off the roof, reducing the risk of leaks and long-term damage.
Drip Edge
The drip edge is a metal flashing installed at the edges of the roof. It helps guide water into the gutters and away from the fascia and roof deck. A properly installed drip edge prevents water from seeping under the shingles, a common issue in poorly executed roof replacements.
Ridge Vent
Ventilation is crucial for maintaining the health of your roofing system. A ridge vent runs along the peak of the roof and allows warm, humid air to escape from the attic. Proper attic ventilation helps reduce energy costs, prolongs shingle life, and prevents issues like mold and rot.
Ridge Caps
Ridge cap shingles are installed over the ridge vent to give the roof a finished appearance while providing protection against water infiltration. These specially designed shingles are thicker and more durable than standard shingles, ensuring the highest point of your roof stays secure.
Architectural Shingles
These are the main visible element of your roof. Architectural shingles are thicker and more dimensionally textured than traditional 3-tab shingles, offering better durability and enhanced curb appeal. They are designed to withstand high winds and harsh weather, making them a top choice for roofing contractors and homeowners alike.
