Before we start: what we know about Baqiq

Team note on Baqiq: 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 Baqiq sits about 83 m above sea level (SRTM open elevation data).

Does a flat roof in Baqiq really need waterproofing every few years, and what does it cost? The honest answer depends on the roof's surface and how much water it collects, but the price range is clear. Liquid roof waterproofing is priced at SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m², and XPS boards cost SAR 12–30 per m². Spray foam sits at SAR 20–45 per m². Rooftop work in Baqiq is not the same job as a basement fix, which is priced separately at SAR 50–150 per m². Owners usually compare these options against how exposed the roof is, since the centre of Baqiq sits about 83 m above sea level, and the roof surface and its slope matter more than altitude alone.

The inspection starts with a walk over the whole roof surface to look for ponding, cracked screeds, lifted edges and old patches that have started to split. The technician checks the parapets, drains and the junction where the roof meets rising walls, because water usually enters at these points rather than through open field. Cracks are marked and measured, since crack injection is priced per metre at SAR 40–120 per m, and any cracks showing signs of moving will be noted for a closer look. Where water has already reached the ceiling below, the inspector checks the top floor apartment for stains and damp patches so the source can be traced upward. The inspection ends with a recommendation for one of the listed systems, matched to the roof's condition rather than sold as a single product.

Before the visit, gather any earlier repair invoices, a note of when leaks first appeared, and the date of the last waterproofing work if you know it. Clear the roof of loose furniture, planters and stored items so the surface can be seen and reached without delay. Make sure the access door or roof hatch is unlocked and that someone with the keys can be present. If the apartment below has had damp, let the occupants know the inspector may need to look at their ceiling. Having these details ready lets the visit focus on the roof itself, and it gives you a clearer basis for comparing the quotes you receive.

In apartment buildings, the floor below is often where a leak shows first.
