A question we get occasionally is about roof leaks and whether just replacing shingles is enough. The simple answer is ‘maybe’. As mentioned in a post written by Alan and Heather Davis (Signs Your Roof Needs Repair), there could be all kinds of issues with your roof.
In their post they describe things to look for but we feel most homeowners and buyers need a visual example of what a homeowner should look for BEFORE major problems occur. The picture in their post shows an obvious roof problem but not all roof problems are obvious.
Shingle Curling & Cupping
The images below show shingles that are curling and cupping. This happens at the end of their life span – right before they start to fall off during the next big storm.
What Causes Shingles to Curl
Your shingles are exposed to direct sunlight and absorb heat. That heat transfers into your attic through convection. Later in the evening when the outside air cools down, your attic is still hot. This trapped heat underneath your shingles causes them to curl. Curled shingles are an obvious indication that the attic has poor ventilation. Many homes we’ve repaired usually have blown-in cellulose insulation covering soffit vents.
Other Issues That Cause Roof Leaks
- Algae and mold growth. Dark streaks running down your roof is usually algae. Mold growth usually happens on the underside of your roof. You’ll need to go up into the attic to see it.
- Damaged flashing around vents and chimney.
- Sand in your gutter. When you can see high granule counts in your gutter, your shingles are either old, have been exposed to extreme weather, or just cheap quality shingles.
- Disintegrating shingles means you haven’t been paying attention to your roof. It means your shingles are long overdue to be replaced and chances are you already have additional damage.
Anyway, if you have a leak, you need to get if fixed before the damage gets worse. If you’ve waited too long and the damage is more than just a leak, you’re better off calling Flood Specialists, Inc. rather than a roofer. A roofer will simply replace your singles so your roof stops leaking. Flood Specialists will replace your shingles so your roof stops leaking AND fix the damage caused by the leak.
