Your roof is one of the most critical components of your home. It shields your family from New Hampshire's brutal winters, heavy rain, and summer storms. But even the best roofing materials don't last forever. Knowing when it's time for a replacement can save you thousands in water damage, mold remediation, and emergency repairs.
Here are five warning signs every Rochester, Dover, and Portsmouth homeowner should watch for.
1. Your Roof Is Over 20 Years Old
Most asphalt shingle roofs are designed to last 20 to 25 years. If your roof is approaching or has passed that milestone, it's time to schedule a professional inspection — even if it looks fine from the ground. Aging materials lose their ability to shed water effectively, and hidden damage can accumulate long before visible leaks appear.
If you're unsure how old your roof is, check your home inspection report or contact us for a free roof inspection.
2. Curling, Cracking, or Missing Shingles
Take a look at your roof after a storm. Do you see shingles that are curling at the edges, cracking down the middle, or missing entirely? These are clear signs that your roofing material has reached the end of its useful life.
In New Hampshire, freeze-thaw cycles are especially hard on shingles. Water seeps into small cracks, freezes overnight, and expands — widening the damage with every cycle. Our residential roofing team sees this kind of deterioration every spring.
3. Granules in Your Gutters
Asphalt shingles are coated with tiny granules that protect against UV rays and add fire resistance. Over time, these granules wear off and wash into your gutters. If you notice a sandy, gritty buildup in your downspouts, your shingles are losing their protective layer.
A small amount of granule loss is normal on newer roofs, but heavy shedding on an older roof is a red flag. This is one of the first things we check during a storm damage assessment.
4. Daylight Through the Roof Boards
Head up to your attic on a sunny day and look up. If you can see pinpoints of light coming through the roof boards, water can get through those same openings. While you're up there, check for signs of moisture — dark stains, streaks, or sagging areas in the decking.
Poor ventilation and damaged soffit and fascia often contribute to this problem. Addressing both the roof surface and the ventilation system ensures a longer-lasting repair.
5. Sagging Roof Deck
A sagging roofline is one of the most serious warning signs. It typically indicates structural damage caused by long-term moisture exposure, rotting decking, or compromised rafters. If you notice a visible dip or sag in your roofline, don't wait — this requires immediate professional attention.
