Bitumen membrane in Taif: the local context

Team note on Taif: 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 Taif sits about 1673 m above sea level (SRTM open elevation data).

Bitumen membrane work for villas in Taif begins with the roof and the parts of the structure that meet water first. The centre of Taif sits about 1673 m above sea level, which is a useful reminder that the town is a high-altitude mountain setting, and that altitude shapes how a technician reads the site before any material goes down. The first check is the condition of the existing surface: whether it is sound, dry enough to take a membrane, and free of loose material. The rate for bitumen membrane is SAR 15–35 per m², so the quoted area should be confirmed on the ground before any figure is agreed, since the final cost follows the measured surface.

Several points cannot be settled from a description alone and are left to the site visit. The technician will look at the exact slope and drainage of the roof, the position of outlets and parapets, and any cracks or movement in the structure. Where cracks are present, crack injection is priced separately at SAR 40–115 per metre, so the length must be measured in person. The same applies to any change of material: a liquid roof waterproofing option is priced at SAR 10–25 per m², and XPS boards at SAR 10–30 per m², and the choice depends on what the surface and the design can take. Nothing in this section should be read as a decision made in advance of inspection.

To help the technician prepare, it is useful to have the villa's roof plan or sketch, the number of levels that drain onto the roof, and any record of past leaks or repairs. Note which rooms sit below the roof and whether any tanks rest on it, because tank internal coating is priced separately at SAR 25–55 per m² and would be a different job. Access arrangements, the height of the roof, and any furniture or equipment to be moved should also be mentioned in advance. With this information ready, the visit can focus on measuring and checking, and the resulting plan will match the actual condition of the villa.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
