There is no single roof waterproofing material that suits every building. The right choice depends on the existing surface, crack movement, drainage, exposure to sunlight and how the roof is used.
Assess the roof before comparing products
Check whether the roof is concrete, metal sheet or precast. Look for ponding water, open joints, weak parapet details and previous repairs. These conditions affect preparation and system selection just as much as the product itself.
Questions to ask before work begins
- Will the system suit the roof substrate and existing coating?
- How will drains, corners and pipe penetrations be sealed?
- What surface preparation and curing time are required?
- What maintenance will the completed roof need?
Request a written scope that explains preparation, application layers and warranty conditions. Explore roof waterproofing options and choose a system after a site inspection.
