What is specific about Alula for roof thermal insulation

Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).

Is a warehouse roof in Alula really worth insulating, given how far the heat already reaches here? The answer depends on the roof itself and the space beneath it. The centre of Alula sits about 697 m above sea level (SRTM open elevation data), and that elevation shapes how the building is used and how heat moves through the structure. For a warehouse, the roof is usually the largest surface exposed to direct sun, so it is where much of the heat load enters. Insulation options are priced per square metre, which makes it easier to compare materials against the size of your roof before any work begins. Spray foam is listed at SAR 20–45 per m², XPS boards at SAR 12–30 per m², and bitumen membrane at SAR 15–35 per m². Liquid roof waterproofing is listed at SAR 8–25 per m², which is a different job from thermal insulation and should be discussed as such.

The inspection itself follows a clear sequence. First, the surveyor walks the full roof and notes its material, slope, and the condition of its existing surface. Second, they check the joints, seams, and any places where previous repairs have been made, since these are the points where a roof most often loses both heat and water. Third, they measure the roof area so the quote can be built from per m² rates rather than estimates. Where cracks or openings are visible at the edges of the roof, crack injection is listed at SAR 40–120 per metre and should be recorded separately so it is not mixed into the insulation figure. The surveyor then confirms which material suits the roof structure and how the layers will sit together, and writes up the findings so you can compare options calmly.

Before the visit, gather a few items so the inspection can move quickly. Have the building plans or any drawings showing the roof dimensions, and note the roof's age and any past repair records. Clear access to the roof hatch or stairs and make sure the surveyor can reach the parapets and edges. If the warehouse has a water tank on the roof, mention it, because tank internal coating is priced separately at SAR 25–60 per m². Finally, write down the questions you want answered, such as expected disruption to stored goods, so the site visit gives you a clear basis for deciding the next step.

For warehouses, work is phased around operations and stored goods.

Signs that call for roof thermal insulation

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

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

Causes we see in the field

• No thermal insulation under the roof protection.
• Old insulation that has deteriorated — we check this before anything else.

Tools we use in Alula

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.
