What Affects Cost

What Impacts Roof Replacement Cost?

Shingle System & Accessories

Your combination of architectural shingles, synthetic underlayment, ice-and-water protection, hip/ridge caps, starters, and the ventilation strategy influences durability and price.

Roof Size & Pitch

More squares mean more material/labor; steeper slopes slow installation and may require additional safety rigging.

Complexity

Dormers, valleys, skylights, and chimneys add flashing detail and time on site.

Condition & Tear-Off

Extra layers, trapped moisture, or soft decking discovered during tear-off can change the final number.

What Could Change Your Final Price

Wood Replacement: Replace soft/rotten OSB or plywood only if needed (priced per sheet) and approved during tear-off.

Underlayment & Ice/Water Shield: Type and quantity of underlayment/leak-barrier at eaves, valleys, and penetrations vary by exposure and code—more protection can add cost but boosts durability.

Flashing upgrades: Chimneys, wall tie-ins, and skylights may require new step/counter-flashing or custom metal work to stay watertight.

Ventilation corrections: Balanced soffit intake with ridge/roof exhaust supports shingle life and warranty compliance; we size airflow to your attic.

Detached structures: Garages/porches add area and transitions. Tight access (alleyways, fences, limited staging) can require manual haul-off and affect dumpster placement.

Ridgetop did our hail storm repairs. For this siding review, I appreciated the Expediter’s communication on supply and dumpster deliveries along with crew times or follow up tasks. We are very happy with how the project turned out from colors to install.

I’m grateful to the team at Ridge Top Exteriors for the excellent job they did re-roofing my house. My Project Manager, Steve Dulock, was unfailingly helpful, professional, and knowledgeable from start to finish. It turned out there were more problems with the old roof than were apparent on the surface. Steve, Tim, and Vic all went the extra mile to make sure everything was fixed properly. I appreciated how well they communicated with me, answered all my questions, and helped me make some decisions. The roofing crew were adept, worked quickly, and were respectful of my property. I have already recommended this company to a couple of my neighbors. They did outstanding work and were a pleasure to deal with.

Jon, from Ridge Top Exteriors was very professional and prompt in regards to our roofing needs. We had missing shingles from a wind storm. Not only did he replace the shingles, he did a full inspection of the entire roof and found several other areas that needed attention that I was not aware of. Thank you very much. Jon gets a 5 star rating out of 5.

Chris Miles was my Project manager. He was helpful in estimating materials and cost factors and very pleasant to work with. Tim Gross the job foreman was very knowledgeable and quality oriented. He was great at keeping us informed of the progress every step of the job. The job ran quickly and smoothly start to finish with great quality of workmanship. I am very satisfied with the finished product and how clean the jobsite was after all work was completed.

Robert, Kevin, and Ridgetop did a good job of guiding us through the whole claims process and the process to get the work done. Kevin also was communicative with us advising us as to when things would be appearing and crews showing up. Then Kevin on his walk through spotted things needing to be addressed including further cleanup and other things regarding the actual work. Also the work crews were polite and worked with us to minimize disruption to our routines. Our house after the repairs looks even better than it did when it was brand new! In short I heartily recommend Ridgetop Exteriors.
