Roof Cleaning and Soft Washing

Wash Off Roof Mold and Algae with a Soft Roof Washing

You can’t prevent spores of algae and moss, Lichen or mildew from landing on your roof. But you can prevent growth. Obviously the best care is preventative care. With regular cleanings you can get rid of the algae before it even becomes an issue, and definitely before it gives way to rot, mold and mildew. 

Algae

Did you know that the algae on your roof is actually eating it? What is it and how did it get there? Years ago shingles were thinner and didn’t have limestone in them and they sometimes ripped off the roof when the wind blew too hard. So they started putting limestone in them for weight. Well that limestone attracts moisture and that moisture makes for a breading ground for growth.

Algae feed on the limestone filler used to give the shingles weight. Over time, as the filler is eaten away, the granules protecting the surface of the shingle lose their hold and begin to wash off. As a result of this loss of shingle mass, the roof loses the ability to reflect heat rays.  

Lichen

Lichen grows on many exterior surfaces including sidewalks, decking, pavers, siding, and even outdoor furniture. Lichen can be especially damaging to roofs, so it's important that it's treated properly to avoid any costly damage.  

Moss

Moss is a plant that grows naturally on just about any surface, including the ground, trees and sidewalks, as well as roofs. It produces tiny spores that become air-borne and land on roofs and other prospective growth sites. During the moist, cooler months, these spores grow into moss.  

Moss absorbs the moisture from the damp environment and establishes roots on your roof causing the beginning of roof degradation. The roots can lift up shingles and constant moisture can lead to bacteria and mold growth. This eventually can lead to holes in your roof and leaks into your home.  

Moss growth is usually greatest on north-facing roofs, roof areas shaded by trees and other places that are not exposed to enough sun to dry out.

Once established, it acts like a sponge, soaking up and storing rainwater. Some of that water then winds up under the shingles through capillary action and soaks into and through the roof underlayment, which is typically 15 - or 30-pound felt. Eventually, it saturates the roof sheathing below.
Insurance companies are becoming wise to the liabilities of a moldy roofs and sidings and the damage it causes. They are threatening cancellation 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.  

No Pressure Soft Washing

You will be speechless at the power of such a safe and gentle cleaning method!  Seeing is believing.
