What is specific about Sharurah for roof waterproofing

Team note on Sharurah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), and that altitude shapes how a roof is checked before any material goes down. Because the town sits high on the plateau, the first things a technician looks at are the roof's drainage falls, the state of existing parapets and outlets, and any standing water or staining left by previous rain. A roof that holds water in one corner will age faster there, so the surface is walked and marked before the pricing discussion starts. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while bitumen membrane sits at SAR 15–35 per m², and those two ranges are often the first comparison a homeowner makes, so the check of the existing surface is what decides which system is realistic.

Several points are left to the site visit itself, because they cannot be judged from a distance. The technician confirms whether cracks are active or old, measures how much crack injection might be needed at SAR 40–120 per metre, and decides whether XPS boards at SAR 12–30 per m² are needed under a new layer for insulation. Access to the roof, the condition of the upstand walls, and whether a tank sits on the roof and would need interior work at SAR 25–60 per m² are also settled on the spot. Spray foam at SAR 20–45 per m² and epoxy coating at SAR 35–90 per m² are only chosen once the surface has been seen, since each depends on how the substrate responds.

To help the technician, note the roof's age, any past repairs, where leaks have appeared inside the building, and whether the roof is used for storage, a water tank or a seating area. Photographs taken after rain, showing where water pools, are especially useful. Clear access to the roof and a stated time window for the work also make the visit more productive. Bring the leak locations to the first call rather than waiting for the technician to find them, because a precise description of where water enters lets the visit focus on the real problem and keeps the scope of the job honest from the start.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for roof waterproofing
