Before we start: what we know about Tabuk

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 centre of Tabuk sits about 762 m above sea level (SRTM open elevation data).

Does a roof in Tabuk really need thermal insulation, and what will it cost? Tabuk sits about 762 m above sea level, so its climate is different from the coast, and the roof is often the surface that takes the most sun. For a residential building, insulation is a question of how much heat reaches the rooms below and how much the cooling system has to work to offset it. The cost depends on the material and the area of roof being treated. XPS boards are priced at SAR 10–30 per m², spray foam at SAR 25–35 per m², and a bitumen membrane at SAR 15–35 per m². Liquid roof waterproofing sits at SAR 10–25 per m², so owners often compare these options against the roof's current condition before deciding.

The inspection begins with a walk over the whole roof surface to look for cracks, ponding areas, blistered finishes and any joints where water could enter. The inspector checks the parapets, drainage outlets and the junctions where the roof meets walls, since these are the spots where insulation and waterproofing most often fail. Any crack that needs repair is measured by length, because crack injection is priced at SAR 40–115 per metre. Where the roof is flat and used for water storage on the top floor, the tank area is noted separately, as tank internal coating is priced at SAR 25–55 per m². The inspector then records the roof area in square metres so that a quote can be built from the material rates above and the condition found on site.

Before the visit, gather the building's basic details: the roof area as best you know it, the age of the building, and any past repairs or leaks you have seen. Note which rooms beneath the roof feel hottest, and whether there are signs of damp on ceilings or walls after rain. If a previous contractor has coated the roof, keep any records of the product used, because this changes the preparation work. Clear access to the roof and to the water tank should be arranged in advance. Having these items ready allows the inspection to focus on the roof itself and gives you a clearer basis for choosing the right insulation option.

For a whole building, a survey of the shared systems comes before unit-by-unit work.

When do you need roof thermal insulation?

These are the signs most often linked to roof thermal insulation:

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

Where the problem usually comes from

• No thermal insulation under the roof protection.
• A common cause: old insulation that has deteriorated.

Tools and methods, and when we use them

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.
