Do I Need a New Roof? 7 Signs It's Time for a Replacement
For most homeowners, the roof is out of sight, out of mind—until something goes wrong. But ignoring the health of your roof can lead to costly water damage and structural issues. How do you know when a simple repair isn't enough? Here are 7 key signs that it's time to consider a full roof replacement.
1. Your Roof's Age
Most traditional roofs are not designed to last forever. An asphalt shingle roof, for example, typically lasts 15-25 years. If your roof is approaching the end of its expected lifespan, it's time to start planning for a replacement, even if there are no obvious problems yet.
2. Curling or Buckling Shingles
Shingles should lie flat against the roof. If you notice patches of shingles that are curling at the edges or buckling in the middle, it's a clear sign that they are failing and can no longer protect your home effectively from the elements.
3. Missing Shingles
This one is more obvious. If you see bare patches on your roof or find shingles in your garden after a storm, it means your roof's first line of defense has been compromised.
4. Moss, Algae, or Dark Streaks on the Roof
While sometimes this can be just a cosmetic issue, extensive moss or algae growth can trap moisture against the roof surface, accelerating wear and tear. Dark streaks, especially on asphalt roofs, can be a sign of airborne algae, which also shortens the roof's life.
5. Granules in the Gutters
Take a look inside your gutters. If you find a lot of asphalt granules (they look like coarse, black sand), it's a sign that your shingles are deteriorating and losing their protective top layer.
6. Leaks or Water Stains in Your Attic
Inspect your attic or top-floor ceilings regularly, especially after heavy rain. Any sign of water stains, dampness, or active drips is a major red flag that your roof's underlayment has been breached.
7. Sagging Roof Deck
A sagging or drooping roof is a serious structural issue. It could indicate that the underlying decking is water-damaged and has become weak. If you notice any sagging, call a professional immediately as this requires urgent attention.
If you see one or more of these signs, it's time to call in a professional for a thorough inspection. An expert can assess the extent of the damage and advise you whether a replacement is necessary.
