What is roof cleaning?
Roof cleaning is the process of removing algae, mold, mildew, lichen and moss from roofs. Also cleaning oxidation on metal roofs. Cleaning can extend the duration of a roof’s ability to function. Algae and other types of build-up often form on the north and west parts of roofs that are shaded or receive less sun, and can reduce a roof’s life expectancy. The presence of soot, dirt, or biomass can affect how much sunlight is absorbed by a roof and thus the amount of heat a building absorbs.
Our safe, effective low pressure roof cleaning service is guaranteed to safely and effectively clean and rejuvenate your roof. The algae on your roof is not only unsightly but it can make your roof less efficient and also reduce its useful life. We only use chemicals and techniques recommended by the Asphalt Roofing Manufacturer’s Association (ARMA).
As your roof ages, airborne spores from algae, moss, mold, and other contaminants land and start to grow on it’s surface. Those ugly black streaks on your roof are an algae that actually feeds on the limestone in your shingles. It’s more than just an eyesore. Over time, the algae, mold, mildew, and moss can destroy your roof shingles. When the roof starts leaking, damage to a home can be extensive and costly.
Buildup of mold or pine needles or leaves can damage your roof and result in leaks. Dirt and grime on a roof can significantly impact the solar gain or loss. In addition a stained and dirty roof can just look bad.
Washing a roof is different than standard pressure washing. It’s important to kill all of the organic material on a roof because in many cases there could be a chemical reaction going on.
Regular roof cleaning, repair, and maintenance are an essential part of your home maintenance routine. As roof cleaning is often overlooked, it increases the chances of major problems occurring with your home. Regular roof cleaning is the best way to ensure a healthy roofing structure. When the time comes to have your roof cleaned, it is essential to hire a trusted and reputable roof cleaning company.
What is Soft Wash/Non Pressure Roof Cleaning?
One safe and effective means to clean a roof is an electric agricultural sprayer system, as originally developed in Florida in the early 1990s. The equipment is used to apply a cleaning solution (typically containing bleach) that kills the algae, bacteria, mold, mildew, moss, fungus and other organic organisms growing on the roof. This is soft washing. The equipment does not use pressure or mechanical means to clean the roof. Using a pressure washer, or any other gas powered device, to clean a roof at more than 100 PSI can damage the roof. The U.S. based Asphalt Roofing Manufactureres’ Association specifies the use of a bleach cleaning solution, without the use of a pressure washer, to remove algae from a roof. ARMA discourages the use of a pressure washer, a flat-surface cleaner or any other mechanical device to clean a roof.
How Long Does Roof Cleaning Last in Houston?
The roof cleaning should last, in most cases, two to three years. Factors such as humidity, access to sunlight, and annual precipitation play a factor. Also, if the neighbors are not keeping up their roofs it will be easier for spores in the air to be transferred back onto the customer’s roof. But generally speaking, there should be little to no growth on the roof for at least 24 months.
How Safe is Roof Washing? Is there Minimal Walking?
Professionals are trained and equipped to caution themselves with the inherent dangers of roof cleaning, unlike a layman that is barely equipped with the required safety measures.
Harnesses are required for high pitched roofs to help avoid falls. Roofs get slippery during the cleaning process. Walking on a roof can damage roof tiles. With roof tiles it is best to use scaffolding or a lift to get close to the tiles without stepping on them.
Types of Houston Roofs Which Can Be Cleaned
All roofs should be cleaned to maintain their reflectivity, keep organisms from growing on them, help them last longer and to minimize the spread of allergens and mold. Asphalt shingle, clay and composite tile, metal, flat, wood and cedar roofs can be effectively cleaned using manufacturer recommended procedures.
What Are Those Black Streaks on the Roof?
Gloeocapsa magma is a strain of algae that infests asphalt shingle and other types of roofs. It travels by wind or animal transfer from roof to roof and can overspread a neighborhood in a short amount of time. This algae eats the shingles and can compromise the roof and cause leakages and roof rot. As rain hits a roof, the algae is carried down the roof surface and forms black streaks. To remove the algae, it must be killed using a manufacturer recommended chemical mixture.
