Now that you're going to have a new roof installed on your home, you want to make sure that it lasts as long as possible.

Here are some step-by-step instructions for cleaning your roof.

Get Rid of the Debris

If you have trees growing near your home, your roof could become a resting place for leaves. Those leaves can become the perfect hiding place for mold growth. As soon as you see leaves gathering on your roof, you should get them cleaned off, especially if you live in a region that experiences high levels of humidity. The warmth that's generated under the leaves can lead to mold growth, as described below.

Look for Signs of Mold

While you're on the roof removing the leaves, you should look for signs of mold growth. If you find mold growing on your shingles, you'll need to clean your roof as soon as possible. Mold that is left untreated can spread to the area below your shingles, and eventually into your home. Mold can grow anywhere there is moisture, including along the edges of your roof and along the seams.
