Understanding the Cost of a New Roof
Here at AC Matthews Roofing & Exteriors, the most common question we get before a roof replacement estimate is “What’s this going to cost?” It’s a fair question, and vague answers are frustrating. Here’s what drives roof replacement cost in Frederick, Maryland, and what you should be skeptical of when getting estimates.

What Drives Your Cost Up or Down
Every roof is different, and when you’re looking into having yours replaced, there are numerous factors that move your estimate in either direction. Here are the top reasons you should be aware of.
The size of your roof is the starting point for every estimate. More surface area means more material and more labor.
Steep roofs require additional safety equipment, slower installation, and more material waste. The steeper the pitch, the higher the labor cost.
Valleys, dormers, skylights, and chimneys all add flashing work and installation time. A straightforward roofline costs less than one with multiple transition points.
Frederick's older homes often have two or three layers of shingles that need to come off before a new system goes down. Tear-off labor adds cost and isn't always reflected in initial estimates from other contractors.
If moisture has reached the OSB or plywood beneath your shingles, damaged sections have to be replaced before installation begins. We discover this during tear-off, update your estimate immediately, and don't proceed without your approval.
What an Estimate from AC Matthews Includes
When you schedule a roof estimate with our team, we provide a line by line breakdown of costs that includes:
- Tear-off and disposal of existing material
- Full material list with product names and specifications
- Decking repair allowance, if applicable
- Ice and water shield and underlayment
- Shingles and ridge cap
- Pipe boots and other penetration flashings
- Permit fee
- Cleanup
If you’re getting quotes from multiple contractors, be skeptical of any estimate that doesn’t include a permit line item. Unpermitted roofing work in Frederick not only leaves you open to subpar workmanship, but it also creates title issues when you sell.

Real Customer Reviews
Posted on Google Ben Denne Great to work with. Very competent. Excellent at keeping the work area clean. Fantastic outcome.Posted on Google Frank Turano ⭐⭐⭐⭐⭐ Excellent Roofing Company — Highly Recommend! Total roof replacement on steep three-pitched story home. I could not be happier with the outstanding job Ramon and his team did on our roof. From beginning to end, the entire experience was excellent. They were on schedule, on budget, and there were no surprise or extra charges. Ramon, our sales representative/project manager, was professional, knowledgeable, responsive, and a pleasure to work with. His crew showed up on time, worked hard all day, and clearly took pride in their work. The finished roof looks fantastic. Just as impressive was how carefully the crew cleaned up afterward. They left our property absolutely immaculate, with no debris or mess left behind. I received five different estimates, and their price was more competitive than the others while still providing excellent quality, workmanship, and service. This was truly a 5-star experience from start to finish. If you are looking for a roofing company that is dependable, professional, fairly priced, and delivers excellent results, I highly recommend Roman and his team! Frank August 2026Posted on Google Tina B. We obtained 3 estimates from 3 contractors. Prices were comparable, but we liked the time Ryan Mckibbon spent with us in person to educate us on options and the best choice for our home. He personally covered a leaking spot on our roof until the roof could be repaired. He answered questions timely and oversaw the entire process. Our roof has been seriously tested with all the rain these last two weeks. All is well. We are very pleased.Posted on Google Christa Wilcox Matthew is a stand up guy who does stand up work! Thank you again! :)Posted on Google Molly Reed- Baltimore & Saratoga Springs I needed a quick fix for flashing on my roof in downtown Baltimore and Ryan was quick to come out, gave me a reasonable quote, and then fixed it promptly. The whole process was easy and enjoyable. Thanks to the AC Matthews team!Posted on Google Mrs. W We were initially referred to AC Matthews Roofing by the Pro Referral program through Home Depot, which only refers vetted, licensed and background checked professionals. It has been great working with AC Matthews and Ramon especially. We have a rather unique roof that needed replacement, it was double layered in portions and not in others which was standard practice in previous decades. It is an additional complication for repairs and it was reaching the end of its lifespan. From the first meeting with Ramon of AC Matthews, it was a great experience. He was thorough and precise. He inspected to determine which parts of our roof had double layers and which parts didn’t, a situation some other companies had missed. When we received the quote, we were very impressed with the transparency and detail in the quote. It was also very reasonable and competitive. They were able to provide us the satellite roof measurements (not all roofs are eligible but ours qualified) to compare with their in-person measurements for additional accuracy checks. It really helped in getting a more precise and complete measurement of our roof. It really was the best practice of measuring twice and cutting once. Ramon also provided all the pictures he took of our roof, which gave us confirmation it was in need of a replacement and repairs were not going to really extend its useful lifespan. We asked many questions regarding the roofing options and types, which Ramon answered very well and in detail. It was very informative and helpful in us making an informed decision about what would be best suited for our situation and roofing requirements. Ramon was very patient with us and the attention explaining precisely and in detail was exceptional and went above and beyond. Everything was very smooth and relaxed, there was no pressure which we appreciated since it’s already a stressful endeavor to tackle a roof replacement even with going the route of insurance coverage.Posted on Google Joseph Lecher My fiance and I just bought a house knowing we would need a new roof almost immediately. We reached out to 4 different roofing companies and ultimately decided to go with AC Matthews. Zack Wolford was recommended to us by a friend and we had an exceptional experience working with him. Zack was professional, informative, and most importantly, very communicative (an extremely rare trait to find among contractors these days). Zack came out and took pictures of our roof to give us a quote and even tarped a rough area on the roof for free since there were heavy rains coming between then and when our new roof was supposed to get installed. Overall, Zack and AC Matthews gave us a phenomenal, hassle free experience for a surprisingly affordable value.Posted on Google Michael Berkey They work hard to make every detail just right. They don’t want any payment until we are completely satisfied. It’s a very pleasant experience to get needed work done, promptly and fairly priced.Posted on Google Elle G AC Matthews and Project Mgr. Ryan McKibbin just finished our roof project and it looks amazing! They converted the slate roof on our 1942 home to a beautiful new shingled roof, replaced the skylights, and installed new gutters and downspouts. We took a looonnnggg time researching roofers and are very happy with our selection. It’s one of the biggest projects for your home so it’s a huge decision. Ryan helped us every step of the way with great patience, skill and professionalism. He answered all our concerns and questions and was very responsive and very present throughout the job. We decided to add insulation in our somewhat challenging (due to a/c handlers) attic, and also needed repairs in the upstairs plaster ceilings due to leaks from the old roof. Ryan and his team took care of everything and it was so convenient for us and everything turned out to exceed our expectations. What a relief to have this all done, and done so well. Thank you, Ryan and AC Matthews!
Frequently Asked Questions About Roof Replacement Costs in Frederick, MD
Estimates vary because of different material quality, different labor rates, different overhead structures, and, sometimes, scope differences that aren't obvious until you compare line by line. A low estimate that doesn't include a permit, uses 3-tab shingles instead of architectural, or skips ice and water shield is genuinely less expensive, and genuinely less valuable. Compare scope, not just the bottom line.
If your replacement is driven by storm damage, your insurer pays the approved scope minus your deductible. The contractor works from the insurance-approved estimate. If you want upgrades beyond the covered scope, you pay the difference.
A roofing square equals 100 square feet of roof surface. A 2,000 square foot home doesn't have a 2,000 square foot roof — the roof area depends on pitch and overhangs, typically 1.2x to 1.5x the footprint. A roofing contractor measures actual roof squares to produce an accurate estimate.
