Roof thermal insulation in Alqunfudhah: the local context

Team note on Alqunfudhah: 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.. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Picture a homeowner in Alqunfudhah whose flat roof is the hottest surface in the house. By the afternoon the slab radiates heat into the top floor, the air conditioners run longer than they should, and the bedrooms stay warm well after dark. Such an owner usually wants a roof that stops heat moving through the concrete, not just one that keeps rain out, and wants to know what that work will cost before committing.

The local facts shape that decision. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. Those figures mean the area is low, flat and close to the coast, so the air carries moisture and salt that can accelerate wear on exposed roof materials. A roof system that is more than a surface finish, with a proper insulating layer and a protective top coat, is better suited to that setting. For insulation the most relevant reference points are XPS boards at SAR 12–30 per m² and spray foam at SAR 20–45 per m², while liquid roof waterproofing runs at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m². Owners should compare these figures as ranges, since the final number depends on the roof's condition and access.

A practical sequence begins with a close look at the existing slab. Note any cracks, ponding areas and old coatings, and where cracks are present, plan for crack injection at SAR 40–120 per metre before anything else is laid. Next, decide the insulation layer: rigid XPS boards suit a level, accessible roof, while spray foam can fill irregular surfaces. Then add the waterproof layer, either a bitumen membrane or a liquid system, and finish with a reflective top coat to reduce heat gain. Request a written breakdown by square metre and by linear metre so each line of the quote can be checked against the ranges above before work begins.

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

Signs that call for roof thermal insulation

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

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

Causes we see in the field

• No thermal insulation under the roof protection.
• A common cause: old insulation that has deteriorated.

Tools we use in Alqunfudhah

From the first visit to the report

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.
