How to Remove Mould on Roofing

Mould and mildew growing on your shingles?

Roofing materials exposed to significant moisture can become vulnerable to mould growth, causing them to raise and rot, particularly on north-facing and shaded sections. This can lead to damaged and deteriorating shingles and other roofing surfaces.

  •   Solution

    If your roof is exhibiting seasonal dirt and grime, use Concrobium House & Deck Wash to thoroughly clean the surface. Use Concrobium House & Deck Wash on wood, asphalt and other shakes and shingle types by following these easy steps:

    1. Apply House & Deck Wash liberally using the hose-end sprayer.
    2. Allow to soak into target surface for 3-5 minutes, but do not allow the surface to dry.
    3. Scrub the area with a stiff bristle brush or broom.
    4. Rinse the surface thoroughly using the ‘Rinse’ setting on the hose end sprayer.

    For tough, embedded mould staining on your roof and associated materials, apply Concrobium Mould Stain Eraser. This no-scrub solution contains no bleach, so it won’t discolour surfaces. Click here for more information on using Concrobium Mould Stain Eraser.
