Homeowners tend to assume that they will know when their roof leaks because they will see water coming from the ceiling. The idea that leaks cause mini waterfalls in a home is a common misconception. It can take weeks or even months before the leak becomes so bad that homeowners spot the water coming from the ceiling. Those who know what to look for can identify potential leaks and call on a Charleston roofing company for help before a minor leak becomes a torrential downpour.
Leaks often occur because shingles shift and leave the underlayment exposed. High winds that pull off shingles may also tear the underlayment, which will allow water to penetrate the deck. The resulting moisture can cause the deck to rot, which then lets the moisture reach the ceiling of the house. Even a rip as small as one inch across is large enough for a leak to form.
The most common sign of a leak is bowing on the ceiling. The water coming from the roof hits the top of the ceiling and begins forming a puddle.
