7 Signs It's Time to Replace Your Roof (Ottawa Valley Homeowner's Guide)
Not sure if your roof needs a repair or a full replacement? Here are seven clear warning signs Ottawa Valley homeowners should never ignore — and what to do next.
Your roof is your home's first line of defence against Ottawa Valley's harsh winters, spring ice storms, and summer downpours. But most homeowners don't think about their roof until there's a problem — and by then, a small issue has often become a costly one.
Here are seven signs that your roof may be past the point of repair and ready for a full replacement.
1. Your Roof Is Over 20 Years Old
Most asphalt shingle roofs have a lifespan of 20–25 years. If your roof is approaching or past that mark, it's worth having a professional inspection even if it looks fine from the ground. Aging shingles lose their protective granules and become brittle, making them far less effective at keeping water out.
2. Shingles Are Curling or Buckling
Curling shingles — either at the edges (cupping) or in the middle (clawing) — are a sign of moisture damage or improper ventilation. Buckling shingles often indicate the roof deck underneath has warped. Both are signs that the shingles are no longer lying flat and sealing properly.
3. You're Finding Granules in Your Gutters
Asphalt shingles shed their granules as they age. If you're cleaning your gutters and finding a significant amount of gritty, sand-like material, your shingles are deteriorating. Granule loss accelerates UV damage and shortens the remaining life of your roof.
4. Daylight Is Visible in Your Attic
On a sunny day, go into your attic and look up. If you can see pinpoints of light coming through the roof boards, water can get in just as easily. This is a serious sign that your roof deck and shingles have failed and need immediate attention.
5. Your Energy Bills Have Crept Up
A failing roof often means poor insulation and ventilation. If your heating or cooling costs have increased without an obvious explanation, your roof may be allowing conditioned air to escape — costing you money every month.
6. You've Had Multiple Repairs in Recent Years
One repair is normal. Two or three in a short period is a sign that your roof is failing systemically. At a certain point, continuing to patch an aging roof costs more than replacing it — and leaves you vulnerable to the next storm.
7. Visible Sagging or Structural Damage
A sagging roofline is a structural emergency. It can indicate rotting roof decking, damaged rafters, or a long-term moisture problem. If you notice any sagging, call a roofing professional immediately.
What to Do Next
If you're seeing one or more of these signs, the best first step is a professional roof inspection. A qualified roofer can tell you honestly whether a repair will buy you more time or whether a full replacement is the smarter investment.
