Say Goodbye to Roof Mold and Mildew

If you have a house with an asphalt shingle roof, you might have noticed unsightly dark stains or streaks on the surface. While many people think this is mold, it is most often actually a type of algae called Gloeocapsa Magma (or blue green algae). Fortunately, this form of discoloration does very little damage to the shingles themselves, but it doesn’t help with curb appeal or resale value.

Mold and mildew are very undesirable in any part of the home, but especially on the roof. They grow on moist surfaces, can cause significant structural damage over time, and are very difficult to remove. They also tend to emit a musty or damp smell, which isn’t pleasant for any member of the household. Mold can also trigger respiratory problems and allergies.

Luckily, there are several things you can do to reduce the risk of mold and mildew growth on your roof. Keep up with a routine maintenance schedule, including frequent cleaning and inspections, and take steps to prevent moisture buildup on the roof.

The most important thing to do to eliminate mold and mildew is to keep the roof itself clean. This means removing any leaves or branches that have fallen onto the roof, and keeping the gutters clear. It is also a good idea to trim back any trees that are overhanging the roof, as they can trap moisture and create an ideal environment for moss and mold to thrive.

There are also a number of different chemicals that can be used to remove moss and mildew from the roof. Chlorine bleach is a common option, but it must be diluted first with water to avoid damaging the shingles. Other products, such as a TSP mixture or a specialty product like Jomax from Rustoleum, may be available for more severe cases. These should be sprayed on and allowed to sit for a few hours, but again, it is important not to use too much pressure as this can damage the shingles.

Another way to protect your roof against mildew and mold is to install a vent system that allows warm air to escape the attic and roof structure. This helps to keep the area drier and less conducive for fungus growth.

Lastly, it is a good idea to have the roof regularly cleaned by power washing professional. These experts have the tools, equipment, products, and skills to get rid of mold and mildew safely and effectively. They can also handle moss, lichens, and other organic growth on the roof to help maintain its integrity and appearance.

Using these tips can significantly reduce the amount of mold and mildew on your roof, and make it easier to keep it clean. It’s always better to prevent mold and mildew from developing in the first place, however, so keep an eye out for signs that it might be starting to grow on your roof, and act fast to ensure that it is not left untreated.
