New Jersey weather is brutal on roofs. Between nor'easters, summer storms, and freeze-thaw cycles, even a well-installed roof takes a beating. Here's how to know when yours needs attention.
1. Your Roof Is 20+ Years Old#
Most asphalt shingle roofs last 20-30 years. If yours is approaching that mark, it's time for an inspection — even if it looks fine from the ground.
2. Curling or Buckling Shingles#
Shingles that are curling at the edges or buckling in the middle are past their prime. This is one of the most visible signs of aging.
3. Missing Shingles#
If you're finding shingles in your yard after storms, your roof's integrity is compromised. Missing shingles expose the underlayment to water damage.
4. Granules in Your Gutters#
Those tiny granules that coat asphalt shingles protect them from UV damage. When they start washing off into your gutters, the shingles are deteriorating.
5. Daylight Through the Roof Boards#
If you can see light coming through your attic, water can get in too. This requires immediate attention.
6. Sagging Roof Deck#
A sagging roof line is a structural issue. It could indicate water damage to the decking or even problems with the foundation supports.
7. Higher Energy Bills#
A failing roof often means compromised insulation and ventilation. If your heating and cooling costs are climbing, your roof could be the culprit.
What to Do Next#
