Roof insulation has no service-specific licence that a customer needs to ask for. Ask for a valid commercial registration that matches the service, and a written quote before work starts.
Spray polyurethane foam roof insulation: SAR 25–120 per m² The final price depends on the area, the type and thickness of insulation, and the condition of the roof.
Waterproofing stops water getting into the roof slab, and thermal insulation cuts the sun's heat coming inside. Sprayed foam does both in one layer, and needs a top coat to protect it from sunlight.
It is best done before the rainy season and on dry days, since insulation materials need a dry surface. If a leak appears, do not put off the inspection: water getting in damages the slab and its steel reinforcement over time.
It depends on the area, the type of insulation and the roof's condition. A house roof is often done within a few days, plus time for the flood test after waterproofing.
Get an inspection before a price, a written quote with the insulation type and thickness, a written warranty, and a flood test before the final payment, and check the commercial registration. This page lists 5 providers in Al-Kharj.
