Non-pressure chemical cleaning is the safest way to clean the roof and ensure that the texture or integrity of the shingles is not damaged. Too much pressure removes granules from the surface of the shingles and damages the roof. Washing without pressure takes longer and requires some professional tools. Moss and algae spores are carried by wind or animals from one roof to another, so entire neighborhoods are often affected.
Moss can seriously affect the performance of asphalt shingles by causing them to roll up and come off, eventually leading to leaks. While algae don't actually damage the roof, they can affect its aesthetic appeal. In addition, climbing on the roof frequently to clean the growth CAN damage the roof and shorten its lifespan by loosening the granules on the shingles. Therefore, it is best to know how to clean the ceiling properly to ensure that you do not have to do it too often.
For best results, mix your chemical cleaner with approximately one gallon of water and one quarter of a gallon of bleach. Pour all these ingredients into a bomb-type garden sprayer and mix them very well. When you're done, climb onto the roof (be sure to take precautions both against a fall and against working with chemicals) and spray the ceiling as thoroughly as possible. The best way to clean roof shingles is to use a garden hose with a vinegar mixture.
Use a sprayer to spray a vinegar solution mixed with dish soap. Be sure to cover the entire roof. Protect your garden and divert downspouts to prevent collateral damage. Let it sit and blow gently a few days later.
Repeat if necessary and then rinse once the ceiling is clean. A combination of bleach and water is an excellent option for cleaning a roof without damaging the shingles. Bleach helps dissolve mold, algae and fungi while restoring the color of shingles. To clean the ceiling, mix a 50-50 combination of bleach with standard bleach.
Add it to a garden hose attachment and spray it to the top of the roof. Saturate a large area of shingles with the cleaner. Start in the bottom row and work your way to the top. Re-spray areas that dry out.
There are numerous products available for cleaning asphalt roofs; the hallway that sells shingles at your local rental store will probably also sell cleaning products. In addition to cleaning roofs, there are other ways to maintain and extend the life of roofs. A high ladder will allow you to spray the entire ceiling from the ladder without walking on the ceiling. If the asphalt shingles look undamaged and the roof looks almost the same as when it was installed, it doesn't need to be cleaned.
It can also save you the cost of investing in a detergent that isn't really necessary to clean the roof of your house. A 50-50 mixture of bleach and water is excellent for cleaning moss, mold and other stains from the ceiling. If the roof slope is not too steep and you feel comfortable working on it, you can clean it yourself and save the dough. This step is essential, since you don't want the vinegar solution to stay on the roof permanently, as it can damage it over time.
If you really want to clean your asphalt shingle roof the right way, there are a few key things to keep in mind. If, on the other hand, you see thick green spots on the ceiling, then you have a moss problem. North, west and shaded areas of the roof are more susceptible to these moisture-causing annoyances. If you have another type of roof, it's important to check with the manufacturer to find out how to clean it.
The best time to clean a shingle roof is when there is no expected rain for several days and when temperatures don't drop below freezing. .
