Why roof thermal insulation differs in Yanbu

Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street. Team note on Yanbu: 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..

Yanbu is about 1.2 km from the sea coast (OpenStreetMap). The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data).

Roof thermal insulation work in Yanbu starts with the site's position, because it shapes what a technician checks first. The centre of Yanbu sits about 6 m above sea level, according to SRTM open elevation data, and the city is about 1.2 km from the sea coast, according to OpenStreetMap. These two facts mean the roof is close to the coastal air and close to the water table in low-lying areas, so the technician looks first at how water and salt-laden air may have reached the roof surface and edges over time. Any staining, lifted finishes or blistering near parapets is noted before any measurements are taken.

Several points are left to the site visit, since they depend on the individual building rather than the city. The technician checks the roof slope and where water collects, the condition of existing waterproofing, whether there are cracks that need injection (priced per metre at SAR 40–120 per m), and whether the roof is accessible for spray foam or boards. The choice between options such as liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², or XPS boards at SAR 12–30 per m² depends on what is found on the roof. Published ranges are only starting points, and the final figure is set after inspection.

Useful information helps the technician work faster and more accurately. Please note the roof area in square metres, any previous repairs, and whether water has entered rooms below. Tell the technician if the roof is used for a water tank, since tank internal coating is priced separately at SAR 25–60 per m² and may need to be assessed on the same visit. Mention any bathrooms or basement spaces beneath the roof, because bathroom waterproofing (SAR 15–40 per m²) and basement waterproofing (SAR 50–150 per m²) are different jobs. Clear photos of problem areas and a note of when leaks appear, such as during rain or wind-driven spray, will help the technician plan the work before arriving.
