Roof thermal insulation in Afif: the local context

Team note on Afif: 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 centre of Afif sits about 1040 m above sea level (SRTM open elevation data).

Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Afif sits in the Najd highlands, and the centre of the town lies about 1040 m above sea level (SRTM open elevation data). That altitude means restaurant roofs there face wide daily swings in temperature, with strong sun through the day and cooler nights. For a kitchen or dining room under a flat roof, the practical effect is that heat moves through the roof structure constantly, so the insulation layer works hard all year. Owners should expect the roof to be a major source of heat gain or loss, and plan the thermal layer as part of the restaurant's running costs, not an afterthought.

The high, dry setting also shapes the service itself. Because the roof takes so much direct sun, the insulation must be chosen for how it performs under heat as well as how it resists water. XPS boards, priced at SAR 12–30 per m², are a common option for a lightweight, moisture-resistant thermal layer under a roof finish, while spray foam at SAR 20–45 per m² can seal irregular roof surfaces and reduce air leaks around service penetrations. Where the roof also needs a waterproof skin on top, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² can be paired with the insulation so that the thermal and water layers work together rather than competing for the same space.

Restaurant owners in Afif often avoid a few common mistakes. Many try to cut cost by fitting insulation without checking how it sits against the waterproof layer, which can trap moisture and reduce the insulation's value over time. Others choose a material only on price and overlook how it handles direct sun on an exposed roof. Some also leave gaps where vents, hoods and pipes pass through the roof, letting heat and cooling escape. Planning the full roof build-up before work starts, and having each layer matched to the local conditions, prevents these problems and keeps the kitchen and dining areas comfortable through every season.

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

Signs that call for roof thermal insulation

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

• 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.
• A common cause: no thermal insulation under the roof protection.

How we choose the tool in Afif

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.
