Full roof replacement for Lexington homes — complete tearoff, deck inspection, ice & water shield at every vulnerable point, and CertainTeed shingles installed to manufacturer spec. CertainTeed Master Craftsman certified. Google Guaranteed. 150+ five-star reviews.
A roof replacement on a Lexington home is a significant investment — and the quality of the installation determines whether that investment performs for 25+ years or starts failing in 10. Lexington’s heavy tree canopy, freeze-thaw cycling, and high property values make it critical to get the details right. We don’t cut corners on any of them.

Every Lexington roof replacement follows the same process — no shortcuts, no skipped steps. Here’s what’s included from start to finish.
Most residential roof replacements in Lexington range from $12,000 to $35,000 depending on roof size, pitch, complexity, and any sheathing that needs replacing. Lexington’s larger homes with steep pitches, multiple dormers, and complex rooflines tend toward the higher end. We provide a detailed written estimate after inspecting the roof on site — no ballpark quotes over the phone.
Most residential roof replacements take 1–2 days of on-site work. Larger or more complex Lexington homes with steep pitches, multiple roof planes, or extensive sheathing replacement may take 2–3 days. We give you a clear timeline before the project starts and manage material staging and crew access to minimize disruption.
We replace it. When the old shingles come off, we inspect every square foot of decking for rot, water damage, and soft spots. Any compromised sheathing gets cut out and replaced with new plywood before the underlayment and shingles go on. This is included in the project scope — we don’t charge surprise fees for reasonable amounts of sheathing replacement, and we communicate with you immediately if the scope changes significantly.
We assess the attic ventilation on every replacement and correct it if needed. Proper ridge vent, soffit intake, or both ensure the roof breathes correctly — poor ventilation is the number one cause of premature shingle failure and ice dams. Many older Lexington homes have inadequate original ventilation that we upgrade as part of the project.
We install CertainTeed Landmark and Landmark Pro architectural shingles — CertainTeed’s most popular residential lines. As a CertainTeed Master Craftsman contractor, we’re factory-trained to install to manufacturer spec, which qualifies every Lexington project for the strongest warranties available. We bring color samples to the consultation so you can choose in natural light.
Yes. The Town of Lexington requires a building permit for roof replacement. We handle the permit application, schedule all required inspections, and make sure everything meets code. You don’t need to coordinate with Town Hall — that’s all included in the project.
