1. Clean the moss off the roof. Having moss on the roof can shorten the lifespan of the roof. There are professional companies you can hire, or you can use a DIY product designed for this. However, you should never pressure wash your roof. This will cause granule loss, which will also shorten the lifespan of your roof.
2. Clean out the gutters. Debris in gutters can cause rainwater to overflow which will eventually cause damage to your roof. These repairs can become costly and can even lead to a completely new roof. Clogged gutters can also cause overflow of water to drip too close to the foundation and compromise its stability.
