Sometimes it is possible to see if roof shingles are going bad without ever having to look at the roof itself. Stains on ceilings and attics are often good indicators of a leak in the roof. If the stain is relatively new, it will feel soft when touched. Older stains, however, feel firm as they have been there for awhile. While water stains that are much older may not necessarily mean there is a problem with the roof shingles, it is always a good idea to maintain caution and monitor for further problems. Mold or wet insulation may also be a primary sign of bad roof shingles.
If a homeowner is able to see the sun shine through the roof in their attic, it is a very good sign that the roof shingles are going bad and either need to be replaced or repaired. If the sun is able to make its way through the shingles, that means that moisture can as well. Many homeowners note a problem with their roof shingles when they see a large increase in their energy bills. This points to moisture coming into the home and leaking onto the insulation, thereby making it ineffective. Cold air is then easily able to pass through the ceiling, causing the heating systems to have to work that much harder.
When looking for exterior signs of bad roof shingles, be careful as to not cause further damage to the roof by walking on it. Remember to have the necessary protection when inspecting a roof, including harnesses and a hard hat. A primary exterior sign of bad roof shingles is damaged or missing shingles. Damage includes wavy edges, curling or cracking. Also check for pieces of the shingles in the gutters and along the surface of the roof. Look to see if the shingles are starting to crack or blister, it is a surefire sign that the roof is either about fail or is currently failing. Mold on the roof’s surface is not necessarily an indicator of bad roof shingles. However, if the mold or algae is only on the roof and not anywhere else on the exterior of the home, it can be a possible sign of bad roof shingles and/or ineffective roofing insulation.
