Check your Fall maintenance

While a dirty roof can detract from its appearance, regular cleaning is not required for the watertightness or longevity of the roof system, except where exposed to harmful contaminants or harsh chemicals. IB membranes are manufactured with a finish that helps the roof remain cleaner for a longer period after installation, but all roofs get dirty. Dust, dirt and organic matter from trees and other materials will settle on the roof, adversely affecting its appearance. Cleaning your installed IB PVC roof membrane is an optional but typical part of routine annual Owner Maintenance to maintain and enhance its appearance; as with most exterior building materials. In humid, wet climates algae or other biologic growth can occur as local environmental contaminants and organic materials are deposited and may require more frequent cleaning and additional measures to control these conditions. Periodic cleaning will improve the appearance and assist the owner in addressing normal exposure and weathering conditions that diminish a roof’s aesthetics and desired reflectivity benefits. More detailed cleaning information is provided on the back of this document.
