Kilraine & Son Roofing

Massachusetts requires a building permit for roof replacement, reviewed by the Westwood Building Department. State code mandates ice-and-water shield at the eaves, valleys, and penetrations — important on the multi-gable, dormered roofs common in Westwood where ice dams concentrate. On mid-century homes a tear-off may reveal older board decking needing repair, while newer custom homes usually have sound plywood sheathing. Mature trees often require trimming or protection during the job. Standard permits move quickly through the building department, and reputable contractors pull the permit and arrange the inspection.

Westwood roofing costs run above the state average, reflecting Boston-metro labor rates and the town's larger, more complex roofs. A standard asphalt-shingle tear-off and replacement generally runs $10,000–$26,000, with big custom colonials carrying multiple gables, dormers, and steep pitches landing at the upper end. Flat or low-slope EPDM sections run roughly $6,500–$16,000. Standing-seam metal runs about $20,000–$45,000. The biggest cost drivers in Westwood are roof size and complexity plus the access challenges of tree-shaded lots, which add labor for staging and debris handling.

Massachusetts requires a written contract and a Home Improvement Contractor registration for most residential roofing work; ask for the registration number and check it before paying a deposit.
