Roofing & Waterproofing

Roofing & Water Treatments


Mosses, lichens and algae cause several problems; they can grow on virtually any roofing material their root systems can bore into solid granite up to 12mm! So once established on tiles, they allow the passage of water into the substrate which gives rise to frost attack and shaling of tiles as well as excreting acids, such as oxalic, which attacks the alkalinity of materials used, further weakening the tiles and bleaching the colour out. Heavy moss contamination when soaked by rain will considerably increase the weight load on a roof. Once established these colonies lead to the rapid deterioration and breakdown of roofing materials eventually necessitating costly replacement.

M.G.C. has specialised for nearly 50 years in the study of microbial attack on buildings. Based on this experience M.G.C. developed a range of systems and treatments to eliminate all types of moss, lichen and algae infections on all varieties of roofs and roofing materials. These treatments not only eradicate the growths but protect the roofs from reinfection.

Does your property suffer from water penetration? resulting in excessive heat loss and damp? Haloseal is the product you need to use to resolve any issues with water penetrating in your property.

Building materials can deteriorate and become porous.  In some houses over the years, water penetration can become a major problem leading to many other secondary problems.  HALOSEAL is non-silicone water proofer; it penetrates deep into the fabric and becomes an integral part of the substrate. As a result of the depth of penetration, HALOSEAL is extremely beneficial in keeping the wall and substrate dry, which reduces excessive heat loss that occurs through damp walls.

Haloseal is Effective everywhere: – old property – new property – bricks – tiles – concrete – render – stonework. Product is simple to apply. One coat application sufficient, treated surfaces stay cleaner longer; can last up to 10 years. See main Haloseal page for BENEFITS
