Waterproofing your roof involves applying a protective coating or membrane that prevents water from seeping through. Common methods include liquid waterproofing membranes, bituminous coatings, or polyurethane-based systems. The surface must be cleaned and cracks repaired before the waterproofing material is applied evenly to create a watertight seal.

Polyurea offers faster curing and higher mechanical strength, while PU membrane provides superior elongation and UV resistance. Both are excellent waterproofing choices.
