A common problem that many Elk Grove Roofing professionals deal with is mold growth on the surface of the roof. Mold easily grows on the roof because it is the most exposed portion of the home to the elements, and every season can create damp conditions that allow it to spread. While mold in and of itself might not become a major problem for the roof, since mold holds moisture, it can cause the roofing materials to become susceptible to rotting over a period of time. Fortunately, just because the shingles have mold growth on them, it does not necessarily mean they need to be completely discarded and replaced. Here are some of the methods roofing contractors might use to remove mold growth and to prevent it from returning on typical roofing systems such as asphalt shingles.

The presence of mold can be determined by examining the shingles. If there are dark streaks found in places, it is probable that mold growth is present. However, what many homeowners believe is that mold is actually algae, which feeds on the limestone substance that is featured in asphalt shingles. Mold tends to thrive on plant matter that has fallen on the roof. While mold, algae, moss, slime, or mildew can each produce different problems for the roof, the main objective for roofing contractors is to remove each of these growths from the surface of the roof in a timely manner before damage occurs.

Depending on the specific type of roof, some contractors prefer to use a cleaning solution that contains trisodium phosphate in order to remove mold from the shingles. After they apply the solution, they must let it sit for about five minutes before rinsing it off with water. However, many contractors do not like this approach because the solution is toxic to other plants, and if it is left on the shingles for too long, it can cause damage to them as well. While contractors can protect the plants from becoming exposed to the solution, it might be difficult for them to prevent the solution from pouring down the gutters and into the rest of the yard.

To avoid these dilemmas, some contractors will use a type of commercial roof cleaning product instead that will not be toxic to plants and will not require rinsing. Some types of sprays offer protection from future mold and algae growth as well, but one of the drawbacks might be that it could take a few weeks or even months to completely get rid of the staining on the surface of the roof.
