Roof waterproofing in Baqiq: with a verifiable technical report

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).

Main roads in or near Baqiq: King Fahd Road.

Baqiq sits at about 83 m above sea level, according to SRTM open elevation data, which places the centre on a fairly low, gently varied plain rather than a high ridge. For roof work, this matters less for altitude itself than for the way rain and dust settle across rooftops in the neighbourhood. Owners should expect that surfaces can collect fine grit between rain events, so a clean, well-prepared substrate is the starting point for any membrane.

Each of the listed rates reflects a different kind of surface and exposure, and the practical effect on the service is in how the scope is chosen. Liquid roof waterproofing is quoted at SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m², so the choice depends on whether the roof needs a seamless film or a sheet system with a stronger body. Where insulation is part of the plan, XPS boards at SAR 12–30 per m² can be added, and crack injection at SAR 40–120 per metre is priced by length because cracks are repaired individually before any coating is applied. A roof that is cracked and then coated without injection will simply show the crack again beneath the new layer.

Owners often avoid the same avoidable problems when they plan ahead. They do not coat over a damp or dusty surface, and they do not compare a per-metre crack repair with a per-square-metre coating as if the two were the same item. They also ask for the substrate to be inspected before pricing, because a roof that is partly a basement or a bathroom below may need the related rates for basement waterproofing at SAR 50–150 per m² or bathroom waterproofing at SAR 15–40 per m². Finally, they keep the written technical report on file, so the work can be checked against the scope that was agreed.

Each job ends with a written report that carries a verification code you can check on our site.

Signs that call for roof waterproofing

The following signs are worth checking before they grow:

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

Causes we see in the field

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

Tools we use in Baqiq

From the first visit to the report

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
