Before we start: what we know about Afif

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.. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data).

Roof waterproofing in Afif starts with the altitude. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), so a technician will look first at how the roof drains and where water collects after rain. At that height the weather and temperature swings can stress roof surfaces, so the first checks focus on ponding, lifted edges, and any cracks that let water reach the layers beneath. Pricing is also set by the method chosen, which is why the technician will ask about the area before quoting. Liquid roof waterproofing typically falls between SAR 8 and SAR 25 per m², bitumen membrane between SAR 15 and SAR 35 per m², and XPS boards between SAR 12 and SAR 30 per m². Spray foam is listed at SAR 20–45 per m² and epoxy coating at SAR 35–90 per m².

What the technician decides only on site is the right system for your particular roof. The condition of the existing layers, the slope, the number of penetrations such as pipes and vents, and whether old coatings need to be removed are all judged in person. Where a crack is the cause of a leak, crack injection is priced at SAR 40–120 per metre, and the length can only be measured once the crack has been traced. The same applies to any water tank on the roof, since tank internal coating costs SAR 25–60 per m² and depends on the tank's condition and access. A visit allows the technician to test for moisture and confirm the source of the leak instead of guessing from the surface alone.

To help the technician prepare, note when leaks appear, whether they follow heavy rain or happen during the hot part of the day, and which rooms below show staining. Share any earlier repair records, the age of the roof, and what finish is currently in place. Clear access to the roof and to the water tank saves time, and it is useful to mention any plans for rooftop additions. Photos of the ceiling stains and of the roof surface, taken after rain if possible, give a clear starting point. With this information the visit can focus on the causes that matter and on a method that suits the roof.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
