Aside from black fungus, there's also another form of black tarnish that might discolor your roof at anytime: soot. A residual matter like that can really make your roofing system look like a meteor missed your roofing by inches but managed to burn part of it. A defective chimney may be the fundamental cause, according to Tampa FL roof clean-up solutions.
Any problems in the flue structure could enable soot to seep out from the fault and stay around the area of the stack. Rain may also be a factor, as it could remove soot from the flue edges as well as help the soot settle on the roof surface. This typically requires a prompt repair of the fireplace to prevent future staining. However Tampa FL roof cleaning also takes priority to get rid of the nasty scorch marks from the roofing system.
The remedy for soot in roofing systems is pretty much the same as that for other kinds of discolorations, a blend of oxygen bleach and water. Specialists suggest using non-chlorine based bleaches, among them peroxide-based ones to lessen the risk of long-term roof covering damage. The ratio is generally one cupful of bleach to one gallon of water.
You will also need a pressure washer for the job, since some amount of force could be needed to remove the hard discoloration. Clearwater roof cleaning solutions make use of various pressure washers as well as roof covering cleansers that could either be utilized from the ground or on top of the roofing. The quantity of pressure perfect for roofing cleaning is typically within 2,000 to 3,000 psi.
Use the cleaning mixture on the soot for at least 10 to 15 moments before scouring the soot out from the surface. Use the same bleach solution in the scouring phase, and be mindful not to scrub too hard, specifically if you have asphalt tiles for your roof material. Rinse using a water hose afterwards, which ought to take out the stain nicely. When the solution empties into the ground, the non-chlorine based bleach won't hurt your plants or blemish your roof.
