How to Determine the Age of Your Roof: A Guide for Erie, PA Homeowners
Knowing the age of your roof is the first step in proactive maintenance. Learn the 5 most reliable ways to track your roof's history.
Knowing the age of your roof is critical for planning maintenance or a full replacement. In Erie, where winter stress is high, an "old" roof can quickly become a liability.
The Reality: Asphalt shingles in Erie typically show significant aging after 15 years due to the constant expansion and contraction from lake-effect temperature swings.
Top Ways to Determine Roof Age
- Home Purchase Documents: Inspection reports and disclosures often list the roof age.
- Building Permits: Local Erie municipalities keep public records of roofing permits.
- Roofing Warranties: Check for manufacturer paperwork left by previous owners.
- Physical Inspection: Look for curling, granule loss, and brittleness in the shingles.
The Granule Check
If you see a large amount of "sand" in your gutters, it means the shingle's UV protection is failing. This is a clear sign that a roof is nearing its final years in the Erie climate.
If you're unsure, EJ's Roofing offers professional inspections to provide an accurate estimate of your roof's remaining lifespan.
