Cleaning a tile roof is a great way to ensure that its true color and natural beauty shine through, while offering protection against damage such as cracks, chips and other breaks. One reason to clean the roof is to extend the life of shingles or other roofing material. While algae isn't harmful to asphalt shingles, moss is, according to ARMA. Moss can cause the edges of shingles to bend upwards, making them more likely to come off the roof when it's windy.
Over time, dirt, moss, and algae can build up on shingles. To preserve the structural integrity of the roof and ensure that your home and belongings are protected from all weather conditions, it is important to keep the roof clean and clean it relatively regularly. There are several ways you can clean shingles, but which methods are the best and which ones should you avoid? If moss, algae and dirt from the roof remain on the shingles and are not removed, this can have several impacts. Your roofing contractor should water nearby plants and cover them to protect them from chemicals before cleaning the roof.
Anti-moss, fungicide and anti-moss treatments can be applied to shingles using an aerosol to kill any living plant on the shingles. But before we get into those methods, let's see why cleaning the ceiling is so important beyond the appearance of the ceiling. Fixing copper or zinc strips along shingles will prevent organisms such as moss and lichens from growing, since when it rains, rain descends onto the roof and absorbs chemicals from metal strips. The accumulation of moss, algae and dirt on shingles can also cause the attic and roof space to overheat, as it covers the shingles and prevents heat from leaving the building.
Doing this regularly will prevent large amounts of dirt and moss from accumulating, and moisture will be able to freely leave the roof space, which means that there is no threat to the structural integrity of the roof and the roof will also be more aesthetically pleasing. Another possible problem with cleaning roofs is that the cleaning product used (usually bleach) can damage any garden plantations or vegetation that grows near your home. Shingles don't dry out in the sun, as moss, dirt, and lichens act as a barrier and keep the shingles moist, which can cause moisture to penetrate the roof. One of the most common methods for cleaning shingles is to pressure wash them, but this is something that is much discussed.
For these reasons, many shingle manufacturers do not recommend the use of pressure washers on their products, and using this method to clean shingles can void any warranty. A good option is to hire a roof cleaner who uses high-pressure washers, which offer powerful burst cleaning solutions.
