Will a roof in Aldawadmi really need waterproofing, and how do you know? The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), and that elevation is only one reason to look closely at the roof rather than assume it is sound. Roofs here are exposed to sun, dust and occasional rain, and the practical way to decide is to match the coating to the condition you actually find. 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. Those ranges help you compare options before any work is booked.

A proper visit begins with a walk over the whole roof surface, looking for cracks, blistering, ponding water and failed joints around drains, parapets and roof penetrations. Where a crack is found, the technician can recommend crack injection, which is priced at SAR 40–120 per metre, and the final choice of coating depends on what the surface reveals. Tank internal coating, at SAR 25–60 per m², is assessed separately if a water tank sits on the roof. The inspection should end with a written list of the areas checked and the recommended treatment for each, so you can see exactly why each line of the quote exists.

Before the visit, clear access to the roof and the stairwell or hatch that leads to it, and move any stored items away from the edges. Note any past leaks, the rooms they affected and the dates you noticed them, because this history helps the technician trace where water is entering. Have your property details and any earlier waterproofing records ready, and make sure someone who can approve the work is available to discuss the findings. Ask for each proposed item to be shown with its rate per m² or per metre, so the quote can be checked line by line against the ranges above.

Each job ends with a written report that carries a verification code you can check on our site.
