Before we start: what we know about Baqiq

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data). Main roads in or near Baqiq: King Fahd Road.

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 first thing a technician checks on a roof in Baqiq is the height of the site, because the centre of Baqiq sits about 83 m above sea level (SRTM open elevation data). That elevation matters less for the insulation material itself than for how the roof is planned, since it shapes the exposure of the top floor to sun and wind and the way rainwater drains off the roof surface. Before quoting, the crew looks at whether the roof already has a waterproofing layer, how the parapet and drains are finished, and whether the slab shows cracks that would need crack injection, which is priced at SAR 40–120 per m. Liquid roof waterproofing, priced at SAR 8–25 per m², and bitumen membrane, at SAR 15–35 per m², are the two options usually compared at this stage, and the choice depends on what the existing surface can take.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to measure the roof area in square metres and confirm whether the top floor has a usable insulation layer, since XPS boards, at SAR 12–30 per m², and spray foam, at SAR 20–45 per m², are not interchangeable on every roof. The condition of the surface, any ponding after rain, and the state of the drains all decide whether the work can start straight away. Where a rooftop water tank sits, its internal coating is a separate job at SAR 25–60 per m², and the technician will note whether that tank needs attention at the same visit. Access for materials to the roof, and whether the apartment block has a shared roof or separate sections, also belong to this assessment.

Information that helps the technician prepare is simple to gather in advance. Please note the number of floors, the approximate roof area, whether the building has a parapet, how many drains there are, and any past leaks or repairs to the roof. Photographs of ceiling stains on the top floor are useful, as are details of any previous waterproofing work and its date. If a basement or bathroom under the roof has also shown damp, mention it, because bathroom waterproofing at SAR 15–40 per m² and basement waterproofing at SAR 50–150 per m² are separate items. Clear notes like these let the technician arrive ready to measure and advise, rather than spending the visit gathering basic facts.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

When do you need roof thermal insulation?

If you notice one of these signs in Baqiq, it is a good moment to talk to the team:

• Strong heat on the top floor
• The AC runs for long hours in summer
• The ceiling stays hot at night

The most common causes

• Old insulation that has deteriorated.
• A common cause: no thermal insulation under the roof protection.

Tools and methods, and when we use them

The steps in order

1. Thermal survey: Hot areas of the roof are mapped.
2. Choosing the system: The material and thickness are agreed in the quote.
3. Installation: The layer is installed and protected.
4. Measurement and documentation: Thickness is measured at spread-out points.
