Why roof thermal insulation differs in Tabuk

The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: 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 first thing checked on a rest house or farm roof in Tabuk is the altitude, because it shapes the whole job. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data), which means nights can turn cool while daytime sun on bare roof slabs is still intense. That swing between heat and cold is why the technician looks first at how the roof currently holds warmth and whether the slab is already exposed to direct sun for most of the day. Roof thermal insulation options such as XPS boards, which are priced at SAR 10–30 per m², are considered against these conditions, along with liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² where the roof also needs a protective layer.

The rest of the assessment is left to the site visit, because it depends on what can only be seen on the roof itself. The technician will inspect the existing surface for cracks, ponding, and old coatings, and will decide whether crack injection (SAR 40–115 per m) is needed before any insulation goes down. The roof's slope, drainage outlets, parapets, and the way the roof meets walls and water tanks are all judged on the spot. If a farm building has a tank on the roof or nearby, the condition of its internal coating (SAR 25–55 per m²) may come up as a separate item. Spray foam (SAR 25–35 per m²) is also a site-specific choice, since it suits some roof shapes better than others and is only confirmed once the surface has been examined.

To help the technician, it is useful to have the following ready before the visit: the approximate roof area in m², the age of the roof slab, any past leaks or patch repairs, and whether the roof is used for storage, sitting, or as a walkway. Note any spots where water has previously stood and whether the rest house or farm is occupied only seasonally. Photos of the roof edges, access points, and any visible cracks are helpful. This information lets the visit focus on what matters most and gives the site team a clearer picture of the right insulation and waterproofing combination for the roof.

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

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

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

Causes we see in the field

• Old insulation that has deteriorated.
• A common cause: 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.
