What Are the Signs of a Failing Roof That Needs Replacement?

Check your roof from the ground with binoculars. Curling, cracking, or missing shingles are clear warnings. Shingles that have lost their granules look bald and worn. If you see bare spots, the roof's protective layer is gone, and water can get in.

Also look for shingles that are lifting at the edges. Wind and rain can tear them off completely. In a climate with cold snowy winters and warm humid summers, repeated freeze-thaw cycles speed up this damage. If many shingles are affected, replacement is often more practical than repairs.

• Curled or buckled shingles
• Missing shingles after a storm
• Granules collecting in gutters
• Cracked or split shingles
• Bald spots where granules are gone

Go into your attic on a sunny day. If you see rays of light coming through the roof boards, that is a direct sign of failure. Gaps between boards or around nails let in both light and water. This means the roof is no longer a solid barrier.

Also look at the roofline from outside. A sagging ridge or dip in the middle indicates structural problems. This can be due to water damage weakening the framing. A sagging roof is dangerous and usually requires full replacement, not just new shingles.

Roofs have a lifespan depending on material. Asphalt shingles often last 20 to 25 years, while metal or tile can last longer. If your roof is near that age and shows any of the signs above, replacement is likely. Check your records or ask a pro to assess the remaining life.

If you live in Detroit, keep an eye on your roof after heavy snow or ice storms. The weight and moisture can stress an already weak roof. Local water damage pros can inspect the condition and tell you whether repairs or a full replacement makes sense. Do not wait until a leak becomes a major problem.
