Does a bitumen membrane suit my roof in Aljumum, and how can I be sure the job is done properly? Aljumum sits about 200 m above sea level, according to SRTM open elevation data, and that is the starting point for any honest assessment. Bitumen membrane is priced at SAR 15–35 per m², which places it among the more economical roof options, and it is a sensible choice for many flat roofs in the area. Whether it suits your particular roof depends on its condition, its slope, and how it is laid, which is why a written technical report matters more than any quoted rate.
The inspection follows a clear sequence. The inspector first walks the full roof surface to record cracks, blisters, ponding areas, and any failed existing sealant, then checks parapets, drainage outlets, and the junctions where the roof meets walls and upstands. Each defect is noted with its location and measured extent, so the report can show exactly where work is needed rather than offering a general impression. Where a crack line runs through the substrate, the inspector records its length in metres, since crack injection is priced separately at SAR 40–120 per metre and the report should show which repairs are truly required. Moisture testing and a check of the existing layers help confirm whether the membrane can be bonded to the surface beneath it or whether preparation must come first. The findings are then set out in the report with photographs and measurements.
Before the visit, gather what will make the inspection faster and more accurate. Have the roof's age, any previous waterproofing records, and details of past leaks or repairs ready to share, and note the areas where water has been seen inside the building. Clear access to the roof, the drainage outlets, and any rooftop plant will let the inspector cover the whole surface in one visit. If you have plans showing the roof dimensions, provide them so the area in square metres can be measured accurately. A clear list of your concerns, such as a specific leak or a planned use of the roof space, will help the report address what matters most to you.
Each job ends with a written report that carries a verification code you can check on our site.
