Your home’s roof is exposed to harsh ambient conditions like sunlight, heat, and rain every day. All of these can cause discoloration in your roof. Your roof takes on an unsightly look when you combine this with a growth of mildew, algae and mold. Your roof not only looks unsightly but all these things can shorten the roof ‘s life. The growth of algae on your roof can also pave the way for moss and lichens to grow which usually thrive in the edges and gullets of the shingles of your roof. Both of these keep your roof damp by holding it in water and moisture. They will elevate the edges of your roof and make it vulnerable to leaks and damage to the wind. Therefore, it is important that you do a daily cleaning of the roof or get a professional to do the job.Have a look at Roof Repair Vancouver WA to get more info on this.
There’s nothing you can do about the environmental conditions but the mold, algae, and mildew can do something. You can do cleaning of a no pressure roof. You’ll need a broom to scrub the surface of the roof, a garden hose and a cleaning solution before you start. Using three parts water and one part chlorine bleach, you can use a commercial cleaner or one that you make at home. To increase the degreasing capability, you can add a cup of powdered detergent to the mixture if you wish.
Before you spray the mixture onto the roof make sure that you have slip-proof shoes, goggles and gloves to cover your hands and eyes. A robust ladder will also be required to climb up and down from the roof. Put the mixture into a pump sprayer once you’ve everything ready and start spraying your roof saturating it. Stand at your roof peak, and work in sections. Start with the lowest part, and gradually work your way up. You can avoid standing on the wet shingles by doing this, since they can be very slippery. Once you have sprayed for at least twenty minutes a section leave on.
You should use the broom for the dirtier parts of your roof to scrub the area to get rid of the dirt, mold , mildew, and algae. Make sure you don’t scrub the area too vigorously, as this may damage the granular surface of the shingle. Rinse it off with garden hose after the cleaning solution has been on the allotted time. It is important to rinse off the chlorine solution, because it could damage your clean roof.
