Roof thermal insulation in Alqurayyat: the local context

The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). Team note on Alqurayyat: 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 owner of a restaurant in Alqurayyat usually runs a busy kitchen under a flat roof that takes the full heat of the day. Rooftop extraction units, air-conditioning plant and storage rooms often sit above the dining area, so the roof becomes a major factor in how comfortable the room feels and how hard the cooling system has to work. Many owners only think about the roof when a leak appears after a rainstorm or when a summer bill arrives that is higher than expected. By then the cost of repair is often higher than the cost of insulating the roof properly in the first place.

The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data), which matters for a restaurant roof. Higher ground in the region can bring wide daily temperature swings, with strong sun during the day and cooler nights. That pattern puts repeated stress on roof surfaces, so materials expand and contract and small cracks can open over time. For an owner, this means the roof system should handle both heat load and movement. A thermal layer that keeps the interior cooler, paired with a waterproof surface that stays flexible, protects both the kitchen's comfort and the building's structure.

Practical steps help owners plan well. First, have the roof surface inspected for existing cracks, ponding water and damaged edges, because these must be dealt with before any new layer goes on. Second, if cracks are found, crack injection is priced at SAR 40–120 per metre, so measuring the total length early gives a realistic budget. Third, choose the waterproofing layer: liquid roof waterproofing costs SAR 8–25 per m², bitumen membrane costs SAR 15–35 per m², and spray foam costs SAR 20–45 per m², each suited to different roof conditions. Fourth, add thermal insulation, where XPS boards cost SAR 12–30 per m², and confirm the chosen system with the contractor before work begins.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

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

The most common causes

• Old insulation that has deteriorated — we check this before anything else.
• 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.
