We clean asphalt shingle roofs or comp, tile roofs, cedar shake roofs, and metal roofs. Though we pressure wash some surfaces again we will only pressure wash a surface if it is safe to do so, pressure washing roofs is bad and will void any warranty you have on your roof. The sheer force of a pressure washer will break down the very part of your roof that's there to protect your home faster and weaken the life of your roof. The only type of roof that we will consider pressure washing would be a metal roof.
The method we use to clean roofs is known as "softwashing" we use chemicals to disinfect/kill algae, moss, and lichen. Here in western washington most roof cleaning is moss removal, when moss starts growing on your roof it starts in the cracks and on the lip of the shingles where they overlap and from there it spreads. When it continues to grow it doesn't just grow out but it also spreads to underneath your shingles as well and if your roof isn't treated all your really doing is giving it a haircut and it will just grow back that much faster. As apposed to pressure washing we use a low pressure rinse to remove moss and all other debris on your roof. Its said that its safe to use water on a roof just as long as its under 1,000 PSI well we use the pressure from a garden hose spicket which is much less than that.
Although the reasons are somewhat debated in the roof cleaning industry, there is definitely one common conclusion and it is that moss is not good for roofs. We have posted a few of the reasons commonly accepted within the industry for why moss is bad for shingle asphalt roofs.
As the moss thickens and grows on an asphalt shingle roof, it can raise the shingles up (much like a jack under a car). When the shingles get raised, it allows water to go under the shingles causing the decking to rot and causing the roof to leak. The raised shingles also pose problems when heavy winds are present because they will catch the wind like a sail and this can cause shingles to be torn or blown off the roof.
A moss buildup on the roof causes more debris to get trapped on the roof. This debris promotes water build up which makes the roof at risk of much more rotting and leaking. Moss can actually damage the asphalt shingle components leaving it to break down faster.
