Roof thermal insulation in Alula: the local context

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

Alula sits about 697 m above sea level, a fact that shapes the thermal conditions a roof must handle. At this elevation the air is drier and the temperature swings between day and night can be wide, so the roof surface absorbs strong sun by day and loses heat quickly after dark. For a service page, this means the insulation choice is not only about heat gain in summer but also about how the layers expand and contract. Owners should expect the roof to work hard across the full daily cycle rather than only during peak afternoon heat.

Because the centre of Alula is at about 697 m, the practical effect is that roof insulation should be chosen with both sun exposure and cooler nights in mind. XPS boards, priced at SAR 12–30 per m², are a common option for thermal insulation, while liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are often compared alongside them. Spray foam, at SAR 20–45 per m², can also be considered where a seamless layer is wanted. Each product covers a different job, so a clear scope agreed before work starts keeps the quote honest and the result predictable.

Owners who plan well before buying or receiving a handover tend to avoid the same set of mistakes. They do not compare a quote for insulation alone against one that includes waterproofing, since the two are often priced separately and sit side by side on a roof. They check that any crack injection, priced at SAR 40–120 per metre, has been addressed before new layers go on top. They also confirm the surface preparation and the product thickness in writing, and they avoid accepting a handover without a walk-through of the roof and a record of what was installed. Taking these steps at the start saves cost and disputes later.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

• 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.

How we choose the tool 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.
