Will my roof leak if I don't have it waterproofed right away? For many property owners in Al Alya, Riyadh, that is the question that matters most, especially when shops and offices depend on a dry ceiling. Al Alya is largely commercial, with shops and offices, and its centre sits at 24.6931, 46.6845, about 2.5 km from the centre of Riyadh, with an approximate radius of 3 km. Because the area sits about 622 m above sea level, roofs here are exposed to the same sun and dust as the rest of the capital, so a membrane that has aged or cracked will not protect the space below for long.
Our inspection starts with a visual survey of the whole roof surface, looking for ponding, blistering, cracks and failed joints around drains and parapets. Where a problem is found, the fix is matched to the defect. Liquid roof waterproofing is priced at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m², while crack injection is priced at SAR 40–125 per metre for isolated linear defects. The inspector records the roof area and any crack lengths so that you receive an itemised estimate before any work begins, and nothing is applied until you have agreed to the scope in writing.
To make the visit efficient, gather the building's basic details and any past repair records, including dates and the materials previously used. Clear access to the roof, the stairwell and the rooftop water tanks helps the inspector see the full picture. If your tenants have reported stains or damp patches, note the rooms and the dates they appeared. Please also tell us whether the roof is in use for equipment or storage, because that affects how the work is planned. With this information ready, the visit can focus on the solution rather than the search for the problem.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
