What is specific about Tabarjal for roof thermal insulation

Team note on Tabarjal: 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 Tabarjal sits about 548 m above sea level (SRTM open elevation data).

Does a roof in Tabarjal really need thermal insulation, and how would a property owner know? Tabarjal sits in the highlands, with the centre about 548 m above sea level (SRTM open elevation data), so the question is worth asking before any work begins. The answer depends on the roof itself, not on the location alone, and an inspection is the only reliable way to decide what the roof needs. A good starting point is to compare the roof's current surface and layers against the materials that are commonly used for thermal and waterproofing work, including XPS boards at SAR 12–30 per m², spray foam at SAR 20–45 per m², and liquid roof waterproofing at SAR 8–25 per m².

The inspection follows a set order. The technician first checks the roof surface for cracks, ponding and worn coatings, then looks at the existing membrane or insulation layer to see whether it is still bonded and dry. Where cracks are present, crack injection is priced at SAR 40–120 per metre, so the length of each crack is measured and recorded. The roof area is measured in square metres, which allows the surface to be matched against the per-m² rates for bitumen membrane (SAR 15–35 per m²) and liquid waterproofing. The inspection ends with a written summary of the materials suggested, their rates and the areas they would cover, so the owner can compare the options without pressure to decide on the spot.

Before the visit, the owner should prepare a few basic items. Gather any earlier roof records, such as previous repairs, leak dates or invoices for past coating work, because these show where water has already entered. Clear access to the roof hatch or stairs, and remove any stored items that block the surface. Note the places inside the building where stains, damp patches or cracked plaster have appeared, since these help the technician trace the source. Finally, decide in advance which parts of the building the work must avoid, such as occupied rooms below, so the scope can be discussed clearly during the visit.

Each job ends with a written report that carries a verification code you can check on our site.
