Roof Cleaning Do's and Don'ts

Your roof needs cleaned as so many do here in the Hartford, Middlesex, Tolland and New London Counties. So you call up one of the listings for pressure washing you find on Google, they give you a quote over the phone, set up a time and come out and clean your roof. At the end of the project you look up and the green is gone and the shingles appear a little darker, but you assume that's just because they are clean after the roof washing. You pay the crew and they go on to the next job. A few weeks go by and you start seeing a lot of granules at the bottom of your down spouts after the big rain storms you had. A few weeks later you get a leak and you call a roofer who comes out and tells you that you need a new roof because your shingles have extreme granule loss, have become brittle and are cracking, which is why you have a leak.

Alright, so let's hope that is a bit exaggerated. The reality is though, that a lot of exterior cleaning services use this tool to remove moss, lichen, mold, and mildew from your roof, and it does a lot of damage like you can see in the picture. Soft Washing helps prevent as much granular loss as possible on your roof while achieving the clean you want.

So what is soft washing? It is a process that combines a specific amount of detergents, depending on the severity, and type of organic growth on your roof, with a low pressure water pump to deliver the mix of detergent and water to your roof at a pressure that is about that of a garden hose or a hard rain. This method also allows you to kill the growth, as opposed to giving it a haircut by using high pressure.
