Do bitumen membranes hold up on a warehouse roof in Aldawadmi, and what does the job cost? The centre of Aldawadmi sits about 976 m above sea level, and a bitumen membrane is one of the waterproofing options suited to large roof areas here. Bitumen membrane for warehouses is priced at SAR 15–35 per m², which gives a property owner a clear basis for comparing quotes against other systems such as liquid roof waterproofing at SAR 8–25 per m² or XPS boards at SAR 12–30 per m².
Before any work starts, the roof is inspected to decide whether a bitumen membrane is the right fit. The inspector checks the existing surface for blisters, loose laps, ponding areas, and damage around drains, parapets and roof penetrations. Where cracks are found in the substrate, they are noted and sealed before the membrane goes down, since crack injection is priced separately at SAR 40–120 per metre. The inspection also records the roof area in square metres so the membrane quantity and cost can be calculated accurately against the SAR 15–35 per m² range.
To make the visit efficient, the property owner should gather the roof plan or a rough sketch showing the warehouse footprint, drainage points and any rooftop equipment. Note any past leaks, the locations where water has appeared inside the building, and the dates of any previous roof repairs. Clear access to the roof and to the internal ceiling areas below helps the inspector trace moisture paths. It also helps to tell the team whether the warehouse is occupied during working hours, so the site visit and later installation can be planned around stored goods and daily operations.
For warehouses, work is phased around operations and stored goods.
