Before anything is quoted for roof waterproofing in Aldawadmi, the first thing a technician checks is the height of the site. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), which means roofs here are exposed to a climate that can differ noticeably from the coast. That elevation matters because it shapes how sun, wind and temperature swings act on the surface, so the choice of system is made with the local exposure in mind rather than copied from a standard template. A visual check of the existing roof comes next, looking for ponding, cracks, lifted edges and any earlier patching, since these tell the technician where water has been getting in.
Several decisions cannot be settled from a description alone and are left to the site visit. The actual condition of the substrate, the slope of the roof, the state of drainage outlets, and whether the roof is accessible for foot traffic or storage all influence the result. The technician will also decide whether a crack needs injection rather than surface coating, and whether a liquid membrane or a bitumen sheet suits the particular roof. Reference rates are useful for understanding the range of cost: liquid roof waterproofing typically falls within SAR 8–25 per m², while bitumen membrane falls within SAR 15–35 per m², and crack injection is priced separately at SAR 40–120 per metre. The real figure depends on what the visit reveals, so these rates are starting points rather than quotes.
To help the technician, it is worth gathering a few details before the visit. Note when leaks appear, whether they follow rain or occur after hot days, and where stains show on ceilings below. Keep any previous waterproofing records, the age of the building, and photographs of the roof surface if you have them. Clear access to the roof and to the rooms beneath it will let the inspection run smoothly. Describing the use of the roof, such as a water tank, rooftop unit or walking area, also helps the technician plan a system that protects what sits on it without disrupting daily life.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
