Bitumen membrane work in Sabya starts with the place itself. The centre of Sabya sits about 40 m above sea level, and the town is about 16.7 km from the sea coast. Because of this, the first check is the roof or slab condition and how water is likely to drain away from it, rather than any concern about salt-laden coastal conditions. Before any price is discussed, the technician should note the falls on the surface, the state of the existing layer, and whether ponding has already left marks.
What is left to the site visit is the part that depends on the actual building. Only a person standing on the roof can judge the substrate, the number and position of penetrations, the upstands at walls, and the condition of the drains and outlets. Bitumen membrane is priced per square metre at SAR 15–35 per m², but the real figure depends on the area measured on site, the number of details to be formed, and whether the old surface must be removed first. These are not things a remote estimate can settle, so the visit is where the scope is confirmed and written down.
Information that helps the technician includes the roof's dimensions, the age of any existing waterproofing, photographs of leaks or staining, and a note of where water has been seen after rain. If the roof is used for a tank or for plant, say so in advance, because a tank internal coating is a separate item priced at SAR 25–60 per m² and needs its own assessment. If the flat roof is insulated underneath, mention whether XPS boards are present, since that changes how the surface is approached. A clear description of these points lets the technician arrive prepared and keeps the written report tied to what the roof actually shows.
Each job ends with a written report that carries a verification code you can check on our site.
