How Much Does a New Roof Cost in Maryland and Pennsylvania?

One of the most common questions we hear is: "How much will a new roof cost?"
It's a fair question. A roof is a major investment, and most homeowners want at least some idea of the cost before scheduling an appointment or having someone come out to their house.

The problem is that most roofing websites either give extremely broad price ranges or ask for your contact information and promise to get back to you later.
At JP Construction Services, we decided there had to be a better way. That's why we created our Instant Roof Quote Calculator for homeowners throughout our Maryland and Pennsylvania service areas.
But before we talk about how our calculator works, let's discuss what actually determines the cost of a new roof.
The #1 Factor: Roof Size
The biggest factor affecting the cost of a roof replacement is the total square footage of your roof. This makes sense when you think about it. Larger roofs require:
More shingles
More underlayment
More ice and water shield
More flashing
More labor
More disposal costs
In short, bigger roofs require more of everything. If there is one factor that impacts the cost of your roof more than any other, it's square footage.
Why We Ask What Type of House You Have
If square footage is so important, why doesn't our calculator simply ask for roof square footage? Because most homeowners don't know it. However, most homeowners do know what type of house they have. For example:
Rancher
Split foyer
Colonial
Cape Cod
Townhouse
Other common home styles

Different house styles tend to have different roof layouts and roof-to-house size relationships. Knowing the type of house helps us estimate your roof size more accurately.
Why Roof Complexity Matters
The next question we ask is about roof complexity. Not all roofs are created equal. A simple roof with a few ridges and valleys is generally less expensive to replace than a roof with:
Multiple dormers
Numerous ridges and hips
Complex intersections
Numerous penetrations
Steep architectural features
Complex roofs typically require more labor, more cutting, more waste, and more installation time. That's why roof complexity is another important factor in determining price.

How We Estimate Roof Size Instantly
There are several ways to determine roof square footage.
Option 1: Physically Measure the Roof
This is often the most accurate method. The downside? Someone has to come to your house, climb ladders, take measurements, and spend time calculating everything. That takes time.
Option 2: Purchase Professional Roof Measurements
Many contractors purchase aerial roof reports from companies that specialize in roof measurements. These reports can be very accurate. The downside is that they cost money and aren't always available instantly.
Option 3: Our Instant Estimation Method
Our calculator takes a different approach. Using your home's square footage, house type, and roof complexity, we can estimate your roof square footage and generate an instant price. The process takes only a few moments, no waiting, no appointments, no sales calls. Just a fast, practical estimate based on the information you provide.

Why Most Online Roofing Calculators Aren't Very Helpful
Many roofing websites advertise "free estimates." Then they provide something like
$8,000 - $25,000. While technically not wrong, that range is often so large that it doesn't really help homeowners make decisions.
Other websites collect your information and tell you someone will contact you later.
That's not really an estimate. It's a lead form. We wanted to create something different.
