Fast, Reliable Roof Replacement & Installation Across Westwood
A full roof replacement on a typical Westwood colonial or cape runs $12,500-$24,000 depending on size and material, and most jobs are completed in 1-3 days with debris cleared before we leave. If your roof is leaking, has missing shingles, or you’re seeing dark streaks on the north side, call us at (844) 563-1816 - a live person answers 24/7, and we’ll get a uniformed technician to your Westwood home for a photo-documented inspection, usually within the same day.
We’ve been driving the wooded streets of Westwood since 1984 - from Blue Hill Drive to the quiet neighborhoods off High Street - and we know what this town’s mature oak canopy does to a roof. The shade is beautiful. It’s also relentless. Our Roof Replacement & Installation team has replaced hundreds of roofs here, and we’ve learned that a Westwood roof isn’t a generic suburban roof. The same trees that make this town desirable accelerate failure modes that contractors from open-lot towns simply don’t anticipate.

Our Roof Replacement & Installation Services in Westwood
Full Roof Replacement
Most Westwood homes are entering their second or third roof cycle. The 1960s-1980s colonials and capes that dominate this market were built with dimensional shingles rated for 20-25 years, but the dense canopy here often cuts that short. On a 1970s colonial on Blue Hill Drive, we found the north-facing slope had Gloeocapsa magma staining within six years of the last install and ice dam damage had rotted the sheathing. We replaced it with GAF Timberline HDZ algae-resistant shingles and extended the ice-and-water shield 24 inches past the interior wall line to meet modern code. That’s standard practice for us in Westwood - not an upsell.
A full replacement on a 2,000-2,800 square foot colonial in Westwood typically runs $14,000-$22,000 with architectural asphalt shingles, including removal, deck inspection, and proper ventilation correction.
New Construction Roofing
Westwood’s infill lots and teardown-rebuilds near Route 109 require roofing contractors who understand Norfolk County permitting and 780 CMR code requirements. We coordinate directly with builders and homeowners on pitch design, material selection, and ice-and-water shield placement from day one. Getting it right during construction means no callbacks. No tear-offs to fix what should have been done once.
Asphalt Shingle Installation
This is what most Westwood homeowners need, and it’s where local knowledge matters most. Standard shingles in this town fail prematurely on shaded slopes. We spec algae-resistant products with copper granules as the baseline - GAF Timberline HDZ, CertainTeed Landmark Pro, or Owens Corning Duration - because anything less is a disservice. The additional cost is $800-$1,400 on a typical roof, and it pays for itself in appearance and longevity.
We also address the ventilation deficits common in 1970s Westwood construction. Many original roofs were built with inadequate soffit intake or ridge exhaust, trapping moisture and cooking shingles from below while the canopy attacks from above.
Metal Roofing
For Westwood homeowners planning to stay decades - and many of our customers are exactly that - standing-seam metal is worth considering. It sheds leaf debris better than asphalt, doesn’t support algae growth, and laughs at ice dams. A standing-seam installation on a Westwood colonial runs $28,000-$42,000, roughly double asphalt, but with a 40-70 year service life. We install Galvalume and painted steel systems from leading manufacturers, with proper underlayment and thermal break detailing for our freeze-thaw climate.

Common Roof Replacement & Installation Problems We See in Westwood Homes
- Algae streaking on north-facing slopes within 5-8 years. Gloeocapsa magma thrives in the constant shade and moisture retention under Westwood’s mature canopy. Standard shingles look filthy long before they fail structurally. We see this on nearly every inspection off High Street and in the neighborhoods west of Route 109.
- Ice dam damage at eaves, especially on homes with inadequate ice-and-water shield. Many Westwood roofs installed before 2010 don’t meet current 780 CMR requirements. The slow snowmelt under heavy tree cover extends freeze-thaw cycles, and water backs up under shingles, rotting sheathing and staining ceilings.
- Premature granule loss on shaded west and north planes. Moisture lingers. Shingles never fully dry. The protective mineral surface washes away years early, exposing asphalt to UV and accelerating cracking. This is a Westwood-specific pattern we rarely see in open-lot towns like Canton.
- Ventilation failure compounding canopy-related moisture. Original 1960s-1970s construction often lacked ridge vents or had blocked soffit intake. Hot, humid attic air meets cold roof decking in winter, creating condensation that mimics a leak. We correct this on every full replacement.

FAQs - Roof Replacement & Installation in Westwood
It’s the tree canopy. Gloeocapsa magma algae colonizes shingles that stay damp and shaded, and Westwood’s mature oaks and maples create exactly those conditions on north- and west-facing slopes. We’ve seen staining within 5-8 years on standard shingles here - half the expected cosmetic life. The fix is copper-granule algae-resistant shingles, which we spec as standard on every Westwood job. Call (844) 563-1816 and we’ll show you the difference on your own roof.
No - not the entire roof, but you need it at eaves, valleys, penetrations, and anywhere ice dams historically form. Massachusetts code (780 CMR) requires ice-and-water shield extending 24 inches inside the interior wall line at eaves, which is more than many older Westwood homes received. Because our tree cover slows snowmelt and extends freeze-thaw cycles, we often recommend extending protection further on problem slopes. We’ll photograph the vulnerable areas during inspection and show you exactly where it goes.
At 40-60 years old, original shingles are past any reasonable repair horizon. Granule loss, brittle tabs, and degraded underlayment mean patches are temporary and often leak adjacent to the repair within a season or two. We recommend full replacement with modern ventilation correction and algae-resistant materials. The investment is $14,000-$22,000 for most Westwood colonials, and it resolves decades of deferred maintenance in one job. We offer free estimates and a permanent 5% senior discount.
Yes - they’re essential here, not optional. The upcharge of $800-$1,400 on a typical roof prevents the black streaking that otherwise appears within 5-8 years and protects granule integrity for the full rated lifespan. In a town with Westwood’s canopy density, installing standard shingles is false economy. We won’t do it unless you insist, and we’ll document why. The copper granules in GAF, CertainTeed, and Owens Corning algae-resistant lines are the only practical defense.
Significant ice dam damage can occur in a single severe winter if the roof lacks proper ice-and-water shield and ventilation. Westwood’s slow snowmelt under heavy canopy extends the danger window well beyond what open-lot homes experience. We’ve opened roofs in February to find saturated sheathing that was sound in October. If you’ve had interior staining, gutter pulling, or icicle formation along eaves, call (844) 563-1816 - we answer live 24/7, and emergency tarping is available to stop active leaks.
