Picture a family who has lived in a villa in Aldawadmi for several years. The flat roof has started to show damp patches on the ceiling below after heavy rain, and they are weighing up whether to repair it themselves, call a contractor, or wait. Many owners in their position are unsure what the work should cost and what they are really paying for. The aim of this page is to set out the published ranges for roof waterproofing and the other common jobs, so the owner can compare quotes on a like-for-like basis rather than relying on a single figure.
The town itself matters here. The centre of Aldawadmi sits about 976 m above sea level, so it is a highland location where the local climate and weather patterns differ from the coast. For a roof, the practical point is that the surface is exposed and must cope with the conditions that actually reach it, so the choice of system should suit the roof rather than being copied from a job elsewhere. Liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². These are the reference ranges for the roof itself, and the gap between the lower and upper ends usually reflects the condition of the existing surface and the access needed.
Begin by measuring the roof area in square metres so that every quote is based on the same figure. Next, look for cracks and note their length in metres, since crack injection is priced at SAR 40–120 per metre and may be needed before any surface system is applied. Ask each contractor to state which system they propose and its price per square metre, and check that any extra items such as crack work, drainage clearing or removal of old material are listed separately. Finally, compare the written quotes against the published ranges above, and ask whether the price covers preparation as well as the material itself.
Prices shown on this page come from our own published price list for the city; the final price is set after inspection.
