Mold is a type of fungus born out of spores that are transmitted through the air. These spores land anywhere they choose, yet more commonly develop in moist areas. For the unfortunate homeowner, mold may arise in different parts of the house, including your roof.
Mold on your roof is a nightmare to eliminate. Do not fret too much – it can be dealt with easily if you treat it immediately and follow the right procedures.
Why the Need to Remove Mold
It has been subject to much debate if mold does in fact harm roofs or if they are just an aesthetic problem. Obviously, having black stains on your roof does not look pretty. However, it has also been found that these can really be harmful to your home depending on the scale of the infestation.
This is especially true for roofs that have many nooks and crannies. There are many surfaces in which mold can grow. The bacteria in mold, if left unattended, can cause aging, rotting, and granule loss to your roof. Extensive growth may even reach the interior of your house.
Get Ready to Clean Your Roof
For very minimal mold growth, sometimes scrubbing with water will do. However, using chemicals and cleaners is the most effective method. When using chemicals like bleach, secure a pair of rubber gloves and a breathing mask to ensure your safety.
Do not forget to protect any plants or sensitive materials at the base of your home that may be damaged by the chemicals that will run down your roof. You can opt to dampen plants with water or cover them up.
- Scrub Mold off Using Bleach
Create a mixture of half bleach and half water. You may choose to add a bit of trisodium phosphate if it is available to you. Put this mixture into a bottle that has a nozzle for spraying. Spray this only on the areas that have mold growth on them. Then, use a hard short-bristled brush to thoroughly scrub down your roof. You may opt to use a long-handled brush to give you better reach.
- Let the Mixture Set
Reapply the spray and allow the solution to soak on your roof for at least 15 minutes, depending on the extent of the damage. This will loosen any bits that were not removed by brushing. Afterwards, rinse your roof thoroughly with water at low pressure.
Alternatives to Chemicals
If you are worried about using certain chemicals, or your roof is particularly brittle, you should know that there are plenty of bleach free cleaners on the market.
You may also opt to go for pressure cleaning, so long as the surface of your roof is hard enough to handle the pressure. To prevent mold from coming back, you may place zinc or copper strips at the peak of your roof. In doing this, rain water will disperse metal molecules down your roof, killing anything that may be damaging.
Just follow these simple steps, and your roof will be free of mold in no time. For further assistance on maintaining your roof or if you need help with roof repair or roof replacement, contact Aastro Roofing right away.
