It is no secret that your roof’s lifelong nemesis is water. Whether it’s a trickle or deluge, water can spell trouble for your roof, especially if there is moss or pine needle build up or if it is nearing the end of its service life. Remember a typical roof is replaced at about 18-22 years of age. But what about too much moisture and humidity? It may not be as pervasive as a rainstorm but too much moisture can surely cause damage to your roof and the rest of your home as surely as rainwater can. A trusted roofing contractor explains how.

It Can Rot Your Roof’s Internal Structure

The decking that holds your roof up is made of wood. And if there’s one thing we know about wood is that it doesn’t like getting wet. Even a small amount of moisture can seep into the internal components of your roof and cause it to warp and bend, while heavy moisture can lead to the wood itself rotting.

It Can Also Undermine Your Roof’s Surface

The majority of homes in the United States are covered with composite shingles. Over time, excess moisture can loosen the granules and cause them to fall off at a faster rate. If you see a lot of tiny sand-like particles in your gutters or downspouts after a rain shower, then it can be a sign that moisture is eroding your shingles, in which case you should give your roofing and siding contractor a call.

It Promotes Mold Growth

Excess moisture can lead to mold growth as well. Mold thrives in dark, moist conditions like your attic. Advanced mold growth can eat away the underside of your sheeting and cause leaks. Mold also spreads quickly, so if you have a mold problem in your attic you could soon have a mold problem in the rest of your house.
