While roof damage is often associated with severe storms involving hail or tornadoes, even just heavy rainfall can cause problems for your roof. The intensity and amount of damage will generally be tied to the current condition of your roof. Therefore, if your roof is already in poor condition, heavy rains could cause it to fail. On the other hand, if your roof is in great condition, heavy rains alone probably won't cause any damage.
Weak spots and cracked tiles or broken shingles create a path in which rain water can seep through and start leaking into your home. This is a slow process that can happen over time, and become worse if not addressed quickly. The design of your roof can also come into play when determining the cause of a roof leak. Inversions in your roof can lead to pooling of water. If you have cracked tiles or rusting metal roofing, having a pool of water build up on your roof can lead to further weakening and eventually a possible leak. In addition, the added weight of water pooling could cause sagging or damage to your roof frame.
In addition to water entering your home, heavy rainfall can cause further damage to already damaged shingles and cracked tiles. Asphalt shingles that have lifted, moved or ripped can be further moved by heavy rain leaving the roof underlayment exposed to water damage. While tiles are designed to withstand water damage (when fully intact and sealed), excessive water running through cracks and gaps can cause progressive damage and weakening. They could break apart from the inside, making them a hazard for future storms. Therefore, it's important after heavy rains and storms to have your roof inspected by a professional roofing company at the Lake of the Ozarks.
After heavy rainfall, damaged shingles can soak up water and remain moist for days. This, as well as the pools of water mentioned before, can trigger mold growth on your roof. Depending on the condition of your roof, it's even possible for the mold to penetrate the roof surface and grow in your home. The presence of mold on your roof and in your home can lead to illness for people and pets.
To decrease the chances of water damage from heavy rains on your roof, be sure to keep your gutters clear of debris and have your roof inspected at least twice a year.
