Before you buy a home in Al Azyzya, Riyadh, or accept a handover, check the roof first. The centre of Al Azyzya sits at 24.5877, 46.7701, about 17 km from the centre of Riyadh, with an approximate radius of 3 km, and it sits about 589 m above sea level. That elevation matters because the roof is the surface that takes the most sun and the most direct exposure to the open sky. Ask for any previous waterproofing records and look closely at the parapets, roof drains and the junctions where the roof meets walls, since these are where water most often finds a way in.
Several roof systems are priced in the local market, and knowing the range helps you ask sensible questions. Liquid roof waterproofing usually falls between SAR 10 and SAR 25 per m², a bitumen membrane between SAR 15 and SAR 35 per m², and spray foam between SAR 20 and SAR 45 per m². XPS boards are typically SAR 15–30 per m², and epoxy coating SAR 35–95 per m². If the seller or previous owner cannot say which system was used, treat that as a question to resolve before the handover is signed, not after.
The remaining points are for the site visit, where a technician can see what a listing cannot show. They should check for cracks, ponding after rain, blistering or lifting of the existing surface, and any signs of past patching. Crack repairs are priced separately, at SAR 40–125 per metre, so the length of any visible crack should be measured and noted. If the building has a rooftop water tank, its internal coating is a separate job at SAR 25–65 per m², and a basement, if there is one, carries its own rate of SAR 55–160 per m². Bring this list to the visit so the technician can confirm each point on the roof itself.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
