Whats Eating Your Roof?

Your roof isn’t just dirty – it’s infested!

Your roof is infested with mold, mildew, algae, lichen, fungas, bacteria etc. They will feed on and destroy asphalt, tile, wood shake shingles, EPDM coatings and even the finish on Metal roofing. The main culprits are Gloeocapsa Magma algae (black Stains) and lichen shown below.

The Gloeocapsa Magma algae (black streaks) on your roof feed on the limestone embedded in asphalt shingles as filler. The filament root system, hunger for limestone, acids from its waste and generated heat from roof darkening combine to decompose and break down shingles. The life span of an infested roof can be reduced by as much as 50%. Cleaning adds years to the manufacturers recommended lifespan of roofing materials.

The body of lichen consists of two organisms living in harmony (symbiosis). One of the organisms, an alga, is able to make sugar by photosynthesis. The other organism, a fungus, is able to dissolve the substrate (tree bark, shingle, stone, etc) upon which the organism is living. It does this by producing weak acids and thus releases nutrients for the whole lichen to feed upon.

Don’t fall prey to other roof cleaning contractors that claim low pressure cleaning…all systems are NOT the same. Roof manufacturers will void the warranty of your shingles if they have been cleaned with any pressure exceeding 200psi. It will remove the granules and cause irreversible damage. The soft wash process is approved by shingle manufacturers and has successfully cleaned over 50 thousand roofs across the country with no problems. Our system is so effective that we provide a 5 year transferable limited warrantee on all residential (full) roof treatments against re-growth. Our soft wash process will guarantee a 100% kill ratio of all mold, mildew, algae and other organic contaminants down to the roots.

A clean roof can save from 20-40% on monthly power consumption, looks better, adds to property value and is healthier. Mold, mildew, fungus and algae are all in the top ten allergens list. Mold and fungus are known culprits of sick building syndrome. Moldy areas are one of the top ten environments looked at for Legionnaires disease break outs.

Conventional (pressure) methods simply strip off the tops of the algae blooms, the roots are still within the surface you are cleaning. Power washing blasts the spores deeper into the surface and spreads them to other areas.

Don’t replace it. Clean it!

NOTE: Insurance companies are becoming wise to the liabilities of a moldy roofs and sidings and the damage it causes. They are threatening cancelation or non renewal of property insurances if not treated properly. In some cases they are mandating replacement before insurance will be given due to their lack of knowledge with treatment options. We have cleaned roofs and houses many times for this very reason.

You name it, we clean it!
