Fast, Reliable Roof Repair Across Lexington
Roof repair in Lexington typically runs $350-$1,200 for most common jobs, and our Roof Repair team usually arrives within 90 minutes for active leaks. We’ve been fixing roofs in Lexington since 1984, from the historic homes ringing Battle Green to the postwar Colonials and split-levels that fill the 02420 and 02421 zip codes. Our phones are answered by a live person 24 hours a day - call (844) 563-1816 and you’ll speak to someone who can dispatch a crew, not a machine asking you to hold.
Lexington sits far enough inland to catch heavier snow than coastal towns, and its mature oak canopy creates problems you won’t find in newer suburbs. We know the difference between a standard shingle repair on a 1970s Cape off Waltham Street and a historically sensitive job near the Battle Green where the Historical Commission reviews your material choices. That local knowledge saves time and prevents callbacks.

Our Roof Repair Services in Lexington
Leak Repair
Lexington’s dominant roof type - a steep-pitched Colonial main roof meeting a lower-pitch garage or ell addition - creates a chronic seam where ice dams form every winter. On a 1960s Colonial on Hancock Street near the Battle Green, we repaired exactly this problem: water had been entering where the main roof’s steep pitch met a lower-pitch garage addition. We replaced damaged flashing and installed a zinc strip to prevent moss - the dense oak canopy had already caused lichen growth on the north-facing slope. Leak repair in Lexington typically costs $350-$750 for standard seam and flashing work.
Flashing Repair
Flashing failure is the leading cause of winter leaks in Lexington’s housing stock. The freeze-thaw cycles here are brutal on metalwork, especially at dormer cheeks and chimney saddles on the multi-plane roofs common in 02421. We replace step flashing, counter-flashing, and valley flashing using materials matched to your existing system - critical in the Local Historic District, where the Historical Commission may reject modern alternatives that don’t preserve period character. Flashing repair in Lexington generally runs $400-$900.
Valley Repair
Open valleys on Lexington’s older Colonials collect debris from those mature oaks, then hold moisture against shingles already stressed by ice dam backup. We repair or replace valley metal, install proper ice and water shield, and ensure drainage paths are clear. Valley work on Lexington homes typically costs $500-$1,100 depending on length and accessibility.
Shingle Replacement
Individual shingle replacement after wind damage or moss degradation is straightforward - unless you’re in the Local Historic District, where color and material approval may be required even for partial repairs. We carry GAF and CertainTeed shingles in stock and can match most Lexington installations from the past two decades. Single-area shingle repair runs $300-$650.
Flat Roof Patch
Split-level homes in 02420 often have flat or low-slope sections over additions or porches that fail at seams and penetrations. We patch EPDM, modified bitumen, and built-up systems, typically completing the work in one day. Flat roof patching in Lexington costs $450-$950.
Vent Boot Repair
Cracked vent boots are a common find on our Lexington inspections, especially on homes where the original rubber has aged through twenty New England winters. We replace with proper flashing kits and sealant rated for our temperature swings. Vent boot repair is usually $250-$450.

Trusted Brands We Service in Lexington
We are authorized installers for seven leading manufacturers - GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral - and we stock common repair materials for Lexington customers at our local warehouse. That means no waiting two weeks for a specialty ridge vent or matching shingles on a color-discontinued line. For historic district work, we can source period-appropriate slate, cedar, or specialty asphalt products that satisfy Historical Commission requirements without the month-long delays that catch out-of-town contractors off guard.
Common Roof Repair Problems We See in Lexington Homes
- Ice dam damage at the seam where steep main roofs meet lower-pitch additions. The heated living space above the Colonial main roof melts snow that refreezes at the colder garage or ell seam, forcing water uphill under shingles. We see this on dozens of Lexington homes every February and March.
- Moss and lichen colonization on north-facing slopes under mature oak and maple canopies. Lexington’s unusually dense tree canopy shades roof sections so aggressively that zinc or copper ridge strips have become standard on our replacement quotes - not an optional upgrade - to prevent callbacks within five years.
- Historical Commission rejection of non-approved materials in the Local Historic District. Properties near Battle Green require commission approval for roofing materials and colors, a regulatory layer absent in neighboring Bedford or Burlington. We’ve seen projects delayed weeks because a previous contractor didn’t know to file the paperwork.
- Nor’easter stress on roofs already loaded with winter snow. Lexington’s inland position means heavier cumulative snowpack than coastal Arlington or Winchester, and the March-April storms often find roofs structurally fatigued after four months of freeze-thaw cycling.

FAQs - Roof Repair in Lexington
Yes, if your property is within Lexington’s Local Historic District, the Historical Commission must approve roofing materials and colors before work begins - even for repairs. This applies to a defined area centered on Battle Green, not the entire town. We file the paperwork as part of our standard process for historic district jobs and source period-appropriate materials from GAF, CertainTeed, and specialty suppliers to avoid rejection delays. Call (844) 563-1816 and we can check your property’s district status.
Lexington’s mature oak and maple canopy shades north-facing roof sections for most of the day, creating the cool, damp conditions moss and lichen need to colonize aggressively. This is far more severe here than in neighboring towns with younger tree cover or more open lots. We treat active growth during repair and install zinc or copper ridge strips on replacement jobs to prevent regrowth - standard practice for us, not an upsell. Call for a free inspection if you’re seeing green patches.
Ice dams at the seam between a heated main roof and an unheated lower-pitch garage or ell addition. The temperature differential creates melt-freeze cycles that force water under shingles at the transition. Lexington’s heavier inland snowpack and frequent freeze-thaw cycles make this the dominant driver of winter emergency calls we receive. Proper flashing repair and ice-and-water shield installation at these seams prevents recurrence. Call (844) 563-1816 for emergency response.
Yes, we repair flat and low-slope sections on split-level homes throughout 02420, typically using EPDM patches or modified bitumen repairs depending on the existing system. These sections usually fail at seams and penetrations, and we complete most flat roof repairs in a single visit. Call for a free estimate - we’ll photograph the damage and give you an upfront price.
Our live phone operators dispatch crews 24 hours a day, including during active storms. For Lexington residents, we typically arrive within 90 minutes for active leaks threatening interior damage. We’ll apply temporary tarping or patching to stop the water, then schedule permanent repair once conditions allow. Save (844) 563-1816 in your phone before the next storm.
