Common questions about this Concord roof replacement
Roof, materials & protection
✓How long does an asphalt shingle roof typically last in Massachusetts?
Many asphalt shingle roofs last around 20 to 30 years, depending on ventilation, installation quality, and exposure. This Concord roof was over 25 years old and was ready for replacement.
✓Do moss and algae on a roof mean it needs to be replaced?
Not always, but heavy growth can trap moisture and speed up shingle deterioration. When combined with age and wear, replacement is often the most reliable path to long-term protection.
✓What shingles were used on this Concord roof replacement?
We installed Owens Corning TruDefinition Duration shingles in the Estate Gray color, paired with the Leak-Proof Roof® System for durable, New England-ready performance.
Ventilation, chimneys & skylights
✓Why replace a power vent with static roof vents?
A balanced ventilation plan helps air move correctly through the attic. For this project, the power vent was removed and static roof vents were installed, paired with soffit vent replacement on the main home.
✓Were the skylights replaced during the roof work?
No. The skylights stayed in place, and we installed new flashing around them to help prevent leaks and protect the surrounding roof system.
✓What chimney work helps prevent roof leaks?
We installed new lead work and crickets on two chimneys to help direct water away from those areas, which are common leak points on older homes.
