Late summer and early fall are both solid times to replace an aging roof, protecting your home from leaks and ice dams before winter. A woman-owned exterior remodeling company and GAF Master Elite certified roofing contractor, Coastal Windows & Exteriors has completed 7,000+ installations since 2011 across 730+ towns in Massachusetts, New Hampshire, and Maine — the right time to replace depends on your roof’s age and condition more than the calendar.
What Homeowners Need to Know:
- Season versus condition: Fall and late summer both work for roof replacement. Schedule a free estimate before winter weather arrives.
- Age guidance: Many owners wonder how long a roof should last. GAF suggests consulting a pro when your roof is beyond 20 years, and once aging signs appear.
- Cost: Replacing an asphalt roof averages $35,701, according to JLC. That roof replacement cost returns roughly 68% at resale.
- Emergency premium: Waiting can backfire, since emergency leak repair can reach nearly $1,800. Such work runs up to twice regular repair pricing.
- Snow load: Roofs commonly handle about 20 pounds per square foot of load. One foot of wet snow can weigh that much alone.
