What is specific about Afif for roof waterproofing

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data). Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Team note on Afif: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..

At 1040 m above sea level, the centre of Afif sits high on the Najd plateau, and that altitude shapes how a roof is checked before any price is discussed. Our technicians look at the roof surface first, because on a plateau the sun is strong through much of the day and the temperature swings between hot afternoons and cooler nights can stress older coatings and open small gaps. Before a single figure is quoted, they confirm which system suits the roof, since 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, and each choice carries a different level of work.

Some things can only be judged on the day. The exact condition of the substrate, the size and depth of any cracks, the slope that lets water run off, and the state of parapets, drains and existing layers all need to be seen in person. Crack injection is priced at SAR 40–120 per metre, so the length and position of cracks decide much of the final figure, and that count cannot be made from a photograph alone. Access, the height of the building and whether the roof is in use are also assessed at the visit, as are any leaks showing inside the rooms below.

To help the technician arrive prepared, it is useful to note when leaks first appeared, which rooms they affect, and whether any previous coating or sealant has been applied. Tell us the approximate roof area and whether there is a water tank on the roof, because tank internal coating is priced separately at SAR 25–60 per m² and is a different job. If the building also has a basement or bathrooms with water problems, mention them now, since basement waterproofing (SAR 50–150 per m²) and bathroom waterproofing (SAR 15–40 per m²) are separate works. Clear notes like these let the visit focus on the roof itself and give you a clearer picture of the work before any decision is made.

Prices shown on this page come from our own published price list for the city; the final price is set after inspection.
