Before we start: what we know about Wadi Aldawasir

The centre of Wadi Aldawasir sits about 683 m above sea level (SRTM open elevation data).

Picture a restaurant owner in Wadi Aldawasir who has spent the day managing a busy kitchen and dining room. By evening, the roof above the dining hall has become a source of worry: the air inside feels warm long after sunset, the air conditioners run harder than they should, and the staff keep asking why the room never feels fully cool. The owner wants a solution that protects the business from heat without a costly rebuild, and wants to know where to start.

The centre of Wadi Aldawasir sits about 683 m above sea level (SRTM open elevation data), which means the town is far from the coast yet still exposed to strong daytime sun and sharp temperature swings. For a restaurant, a roof that absorbs heat during the day turns straight into indoor warmth and a higher cooling load. Thermal insulation on the roof addresses this directly. Options such as XPS boards, typically SAR 12–30 per m², can be fitted beneath a new finish, while liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² protect the structure from the moisture that can weaken insulation over time. Spray foam, at SAR 20–45 per m², is another route where the roof shape suits it. Each choice has a different cost and suits different roofs, so comparing them against the building's actual condition is worthwhile.

A practical approach starts with an inspection of the existing roof surface, looking for cracks, ponding areas and any old coatings that have failed. Next, mark the cracks and measure the roof area so that quotes can be compared on the same basis. Where cracks are present, crack injection at SAR 40–120 per metre should be completed before any insulation or membrane goes down, so that water cannot travel under the new layers. Then select the insulation and waterproofing system that matches the roof's size, slope and budget, and confirm that the chosen finish can handle direct sun. Finally, schedule the work outside peak dining hours, keep the kitchen extraction and air conditioning protected from dust, and check the room temperature in the weeks after completion to confirm the improvement.

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

When do you need roof thermal insulation?

These are the signs most often linked to roof thermal insulation:

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

The most common causes

• A common cause: old insulation that has deteriorated.
• 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.
