Roof Cleaners

Roof cleaners and roof cleaning chemicals are as important for roofing maintenance as topcoat finishes. It is an intrinsic part of any roof repair project, including repair work, replacing or fixing loose sheeting or tiles, recolouring surfaces and materials, or applying a solar and heat reflective finish coat. From pitched to flat roofs, and industrial scale buildings and factories to agricultural properties, each falls victim to the relentless onslaught of weather elements, bird droppings, brushes with close proximity trees, wind damage, moss, algae, and more. Products listed in this category are excellent for both surface cleaning and preparation prior to applying subsequent elements of a roof repair or waterproofing system. 

Among the most popular roof cleaning products are fungicidal washes, which are most commonly used to clean discoloured red roof tiles, slate, Plastisol, asphalt, rolled felt, and parapet brickwork. Please check product datasheets, as some products are also suitable for moss and algae build-up on masonry and guttering - which may go unnoticed until it blocks roof drainage!
