Roof thermal insulation in Alqurayyat: the local context

The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). Team note on Alqurayyat: 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 most common problem with roof insulation for rest houses and farms is heat reaching the living space through a thin, exposed roof slab, so rooms stay hot long after dark and air conditioning runs far harder than it should. Owners often notice it first in summer, when upper rooms and storage areas become uncomfortable. Before choosing a method, the roof surface, slope, access and how the building is used all need to be checked, because a rest house used only at weekends has different needs from a farm store that holds stock.

In Alqurayyat, the centre sits about 497 m above sea level (SRTM open elevation data), which points to a higher-elevation setting where days and nights can feel quite different in temperature. That matters for insulation because the aim is to slow heat gain through the roof while also managing moisture and sun exposure on the surface. Options range from XPS boards at SAR 12–30 per m² to spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m². Each has a different job: boards and spray foam add thermal resistance, while liquid coatings and membranes mainly protect against water. Many roofs need a combination, so the work should follow what the survey finds rather than a single product chosen in advance.

Before the visit, ask the provider to confirm which roof type they expect to see, whether the surface is flat or sloped, and whether any existing waterproofing or cracks need attention first. Ask how they will handle access to the roof, how long the work is likely to disrupt use of the property, and whether any water tanks on the roof will need coating, which is priced at SAR 25–60 per m². Request a written quote that separates each material and area, and ask what cleaning and surface preparation is included. A clear answer to these points will help you compare offers on equal terms.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

If you notice one of these signs in Alqurayyat, 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.
• No thermal insulation under the roof protection.

Tools and methods, and when we use them

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.
