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.. Main roads in or near Baqiq: King Fahd Road.

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data).

Does a villa roof in Baqiq really need waterproofing, and what will it cost? Baqiq sits at about 83 m above sea level, and the roof is the surface most exposed to sun, heat and any rain that does fall. For liquid roof waterproofing, the typical range is SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m². Other options such as XPS boards at SAR 12–30 per m² and spray foam at SAR 20–45 per m² are also used on roofs, so the right choice depends on the roof's condition and how it is used. Owners with a water tank on the roof should note that tank internal coating is priced separately, at SAR 25–60 per m².

The inspection usually begins with a walk across the whole roof to look for cracks, blistering, ponding areas, and failed joints around parapets, drains and rooftop fixtures. Where cracks are found, crack injection is quoted per metre at SAR 40–120 per m, and the surveyor will measure their length so the repair can be priced accurately. The surveyor will also check the condition of any existing coating, noting whether it is peeling, chalking or cracked, because this decides whether it can be overlaid or must be removed first. Each area is measured in square metres so that the quote reflects the actual surface being treated rather than a rough estimate of the whole roof.

Before the visit, the owner should clear the roof of loose items, planters, satellite equipment and stored materials so the surveyor can reach every corner and edge. It helps to note any past leaks, the rooms beneath them, and the dates they were noticed, since this shows where water has been getting through. Access to the roof should be arranged in advance, and any water tank should be emptied or at least accessible if its coating is part of the scope. Having these details ready lets the visit focus on the roof itself and makes the resulting quote easier to compare with other options.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

Signs that call for roof waterproofing

The following signs are worth checking before they grow:

• The old waterproofing is cracking
• Water pooling on the roof
• Stains on the top-floor ceiling after rain

Where the problem usually comes from

• Cracks in the roof slab — we check this before anything else.
• Wrong falls towards the drains.
• Damaged waterproofing around tank and AC bases.
