There are many causes for roof defects, but the good news is catching most roofing problems early can help you avoid costly roof replacement. Here are some of the most common roof problems.
Dipping or Sagging
If your roof is sagging or dipping, it’s a sign that there is a problem that needs your immediate attention. If you ignore the sagging, there is a chance your roof can collapse. In this case, you will likely bear the full cost of replacement as most insurance companies require that you mitigate damage.
A few common reasons for a sagging roof: the materials are faulty, it has suffered serious water damage, or it’s bearing too much weight. Sometimes ceiling joints actually pull away from the roof rafters and cause the outer material to sag. In some cases, roofing problems with shingles look worse than they are. It’s possible that the shingles are the problem if they seem warped or the sagging started after the shingles were installed. If the shingles seem to run in straight lines, the structure itself could be bowing.
A leak is an obvious sign that there is something wrong with your roof, such as damaged flashing, shingles, or tiles. While you may be tempted to ignore a minor leak for a while, there are several dangers a leaky roof can pose.
- Damage to the ceiling and attic. The water will cause stains on the ceiling and damage paint, fans, and lights. More importantly, the drywall in your ceiling will quickly absorb the water and become structurally weak. This can cause your ceiling to collapse without warning.
- Mold and mildew. Mold spores can germinate in 12 to 48 hours with the right conditions, such as moisture and darkness. Once mold begins to grow behind your ceiling and walls, it can spread through your HVAC system.
- Fire hazard. A leaking roof can pose a serious fire hazard if the water reaches any electrical wiring and causes a short.
- Higher utility costs. The water intrusion will damage insulation. This makes it harder to keep your home air conditioned. This means higher cooling bills in the hot Texas summers.
- Compromised integrity of the roof. Of course, a leak can also damage the rafters, joists, wall framing, fascia boards, and trim of your home and roof. The longer the leak continues, the greater the damage and the eventual repair cost. In a worst-case scenario, a leak can also cause your roof to collapse.
