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 to be on the higher end. We provide a detailed written estimate after inspecting the roof on site.
If your roof is under 15 years old and the issue is isolated — a flashing failure, a few missing shingles, or localized ice dam damage — repair usually makes sense. If the shingles are 20+ years old, showing widespread granule loss or curling, or you’ve had multiple repairs in recent years, replacement is the better investment. We inspect and give you an honest recommendation.

Yes, absolutely. Lexington is inland with heavy tree canopy that shades roofs and holds snow longer. Homes with inadequate attic ventilation or insulation are especially prone. We assess and correct ventilation on every replacement, and install full ice & water shield at eaves, valleys, and penetrations. On repair projects, we address the underlying ventilation issue along with the visible damage.
Yes. Lexington has a significant stock of antique and historic homes, some dating to the 18th century. We understand the care required — steep pitches, original framing details, tight access, and preservation considerations. We treat every historic property with the respect it deserves while ensuring the roofing system meets modern performance standards.
Yes. We pull the building permit through the Town of Lexington, 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.
