Before we start: what we know about Alqunfudhah

Team note on Alqunfudhah: 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 Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Alqunfudhah is a coastal town, and the centre sits about 7 m above sea level, so the first thing a technician checks on a roof is how water moves off it and where it can pool. The town is also about 0.4 km from the sea coast, which means salt-laden air is a regular part of the picture, and surfaces and fixings should be inspected with that in mind before any insulation is chosen. Roof thermal insulation is priced by the square metre, and the published offers for the relevant systems in this area fall into a clear range. Liquid roof waterproofing is listed at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m². These figures are offers, not quotes, and the final price depends on the condition of the roof and the system selected.

What is left to the site visit is the part that no published figure can settle. The technician needs to look at the actual roof: the slope, the drainage outlets, the state of the existing surface, and any cracks or blistering that would change the preparation work. Crack injection is listed at SAR 40–120 per metre, so the length and location of cracks found on the day will shape the cost. Where the roof meets walls, parapets, or service penetrations, the detailing must be assessed in person. The visit is also where the homeowner can confirm access, the area to be treated, and whether any adjacent surfaces such as a tank or bathroom need matching work.

Information that helps the technician includes the approximate roof area, the age of the existing roofing, any history of leaks, and whether the roof is used as a living or storage space. Photographs of problem areas taken after rain are especially useful, as they show where water actually collects. Knowing whether a water tank sits on the roof also matters, since tank internal coating is listed separately at SAR 25–60 per m² and may be part of the same job. Bringing these details to the visit lets the technician compare the options against the published ranges quickly and give a clearer picture of what the work will involve.

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