Picture a homeowner in Khamis Mushait who has a flat or villa roof that has started to show damp patches on the ceiling below after a rainy spell. The roof is large, the family relies on it for drying laundry and sitting outside in the cooler evenings, and the owner wants a durable fix without paying for work they do not need. Like many owners in the city, they are weighing a bitumen membrane against other options before they request quotes from contractors.
The high elevation of the city centre, at about 1998 metres above sea level, means the area is cooler than many parts of the kingdom, but roofs here still face strong sun, wide temperature swings between day and night, and occasional heavy rain. For a bitumen membrane, the published range of SAR 15–35 per m² is a useful starting reference for the material and application on a roof. Because the rate is given per square metre, the total depends entirely on the measured area, so the owner should confirm the roof dimensions before comparing offers. Those who also have a water tank on the roof, or damp in a basement, should note that tank internal coating and basement waterproofing are priced separately and should not be mixed into the same quote.
A practical sequence helps. First, measure the roof area in square metres and note any upstands, drains and cracks. Second, mark every crack and estimate its length in metres, since crack injection is priced per metre at SAR 40–115 per m and may be needed alongside the membrane. Third, ask each contractor to state the rate per square metre, the scope of surface preparation, and whether the price includes primer and edge detailing. Fourth, compare the quotes line by line against the published ranges. Finally, agree on a written schedule and confirm the warranty terms in writing before any work begins.
Prices shown on this page come from our own published price list for the city; the final price is set after inspection.
