The roof takes the full force of Riyadh’s sun and rain. Roof waterproofing stops water reaching the slab, protects the reinforcement from corrosion and noticeably lowers the temperature of upper floors — which means smaller cooling bills.
Roof systems we install
Bitumen membrane waterproofing
Torch-applied bitumen rolls over a primer, overlapped and turned up the parapets. A proven, economical way to stop leaks, usually protected by tiles or a screed.
Spray foam (polyurethane) insulation
A seamless sprayed layer that insulates against heat and water at once, finished with a UV-resistant top coat. See spray foam insulation in Riyadh.
Liquid acrylic / polyurethane coatings
Flexible, joint-free membranes that can be applied directly over existing tiles — ideal for fixing leaks without demolition.
Insulation boards
Polystyrene boards placed over the waterproofing layer and under the tiles for high thermal performance on new roofs.

FAQ
How much does roof waterproofing cost in Riyadh?
Pricing is per square metre and depends on the system (waterproofing, thermal or both), roof size, condition and whether old layers must be removed. We quote in writing after a free inspection.
What is the best roof insulation for Riyadh?
A combined system usually performs best: a waterproofing layer (bitumen or liquid membrane) plus thermal insulation with spray foam or insulation boards.
Can you waterproof a roof without removing the tiles?
Often yes — after treating joints and cracks we can apply a clear or acrylic/polyurethane coating over the existing tiles.
How long does it take?
Most villa roofs are finished in one to three days, followed by a flood test.
