Roofs, whether stained by algae or not, are washed using one of three different methods, each with its own set of benefits and drawbacks. Pressure washing and the use of solutions containing chlorine bleach or sodium hydroxide are two of these processes. These techniques clean roofs efficiently without causing major side effects when used correctly and only once. The problem is that they normally need to be done every six to eighteen months to stay clean.Do you want to learn more? Visit EZ Roof and Construction in Houston, TX
Washes with a Chlorine Solution: The application of a chlorine bleach solution necessitates much less rinsing than the other two approaches, allowing for a cleaner procedure to be completed in less time. One advantage of a faster method is that the roof suffers less wear and tear. Chlorine, on the other hand, may be poisonous to certain people and plants, so take precautions to protect workers and tenants, as well as the property itself, from spray runoffs. Roofs made of asphalt shingles are particularly well suited to this form of cleaning.
Roof Cleaning with Sodium Hydroxide: This form of roof cleaning can be very efficient at degreasing roofs. Since the sodium hydroxide must be thoroughly rinsed, this cleaning process takes much longer than chlorine bleach cleaning. As a result, a roof’s vulnerability to damage increases. On asphalt shingle roofs, a force of 100 psi is sufficient to wash away the cleaning solution, but the force is sufficient to allow some asphalt granules to be washed away during the rinsing process. Sodium hydroxide is advertised as being safe to use, but it can actually be harmful. During the application and rinsing process, make sure the solution does not run off or come into contact with people, plants, or anything else in the surrounding area. Furthermore, since sodium hydroxide is corrosive, any residues left on the roof, especially those made of asphalt shingles, can cause harm.
Washing with high pressure: Power washing may be used to clean a concrete, barrel tile, or metal roof. Since power washing does not require the use of chemicals, it is an environmentally friendly form of roof cleaning. Power washing, on the other hand, takes a long time and may put more pressure on the roof. The thin layer of colouring on coated roof tiles can be quickly washed away with power washing. If you have a concrete roof, power washing will bring out the natural grey colour of the concrete, which will necessitate painting or staining the roof later.
