We clean roofs chemically, with low pressure and also with high pressure water. The pressure used during the chemical cleaning process is equal to the pressure you find coming out of an average garden hose. This is the preferred method of roof cleaning according to the roof tile manufacturers. The chemical treatment is applied multiple times over the roofs surface until all of the mold/mildew is removed. We take all precautions to avoid any negative affects from the chemical mixture reacting to landscaping. We water in landscape vegetation before and during the application process and cover specific landscaping where needed.
*We carry full liability and roofers workers compensation insurance and can provide copies of certificates or originals sent from our insurance agent.
