Mold is what creates those dirty roof stains to appear; once your roof has mold spores planted on it, you can virtually watch the mold spread. This home-damaging process typically starts with a few black streaks, often under the limbs of a tree, and then over a short period of time the mold spreads across your entire roof. This mold damages your roof shingles by pulling up the reflecting stones, thus reducing your roof life; if you have a tile roof, the mold eats away the glaze finish of the tiles. Leaving mold on your roof will significantly reduce it’s life, increase your home cooling costs, increase your chances of tracking mold into your home, and if you have a pool the mold contaminates it with each rain drop splashing off your roof into it.
Pressure washing has been done on some roofs by others, but that annual method of cleaning only shaves off the visible surface of the mold, leaving it’s roots. Even worse, the high pressure spray dislodges many of the reflective granular stones on the shingles, which results in the roof’s loss of effectiveness in reflecting heat; if your roof has tiles, pressure washing removes the factory glaze off of them, leaving a look of pitted clay. In contrast, our soft-cleaning method uses a non-pressure gentle rinse that removes not just the visible stains but also the mold’s damaging roots. Our special chemical mixture achieves results that last for five years, and often longer. And we always take great care to protect your ground foliage, decorations, and any equipment such as air conditioning units and pool pumps.
Dirty roofs cause higher electrical bills, exemplified by comparing a white car and black car in the heat of the summer. Which car will feel cooler inside? It’s the same with your roof. Having black mold on your roof raises your energy costs by up to 10%. Having your roof professionally cleaned provides an instant payback, with savings in your pocket each month.
