Your roof goes through a lot of wear and tear. It is constantly exposed to the damaging rays of the sun and the heat it generates. It has to take the brunt of heavy rainfall and hail, as well as the weight of snow. On top of that, replacing your roof is very costly, so taking good care of it is very important.
One of your main concerns when it comes to the health of your roof is to keep it from being exposed to standing water. Water can do damage to all different types of roofing materials, even though it might be in different ways. Rust, mold, moss, rot are the most common issues, and they can cause other, secondary problems.
You should make sure that your gutters and downspouts work properly and funnel the water away from your roof. In a heavy rainstorm, it might not be that easy to get your gutters flowing again, so make sure that you check them before rain is expected.
