Our technical writing on cold-applied waterproofing and roof restoration, and our coverage in specialized construction media.
The application season is over, but this is when good projects take shape. Whether the roof is a low-slope elastomeric membrane or metal, observing, documenting, scheduling the inspection at the right time and comparing equivalent quotes all happen before the first day on site.
Replacement is often the default reflex when a roof starts showing signs of reaching the end of its service life. Yet what really decides isn’t the rust or the ceiling stain. It comes down to a few specific criteria, and one question few owners think to ask: how thick will the coating be applied?
Several Montreal boroughs require a reflective covering on low-slope roofs. The default response is often a new white sheet membrane. A cold-applied silicone restoration reaches the same target while keeping the existing roof in place.
Roofers’ skepticism toward liquid coatings goes back to products launched in the 2000s that shrank, oxidized or peeled off within two summers. The problem was never cold application, but the formulation. A look at what changed with the arrival of high-solids silicone, and at the limits that still rule a roof out.

Imper Guard is a distributor of roof waterproofing and restoration products, serving Quebec, the Maritimes and Eastern Ontario.
Our coatings and sealants are cold-applied and flame-free, and integrate with the existing roof system to renew its watertightness. They make it possible to restore a roof rather than replace it, with a 10- to 20-year manufacturer’s warranty certificate depending on the system and the thickness applied.
Our products are installed by a network of certified applicators, and sold through our online store and by the pallet. Technical data sheets and safety data sheets are available for the entire product line.
