What is specific about Sakaka for roof waterproofing

Team note on Sakaka: 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 Sakaka sits about 555 m above sea level (SRTM open elevation data).

Sakaka sits at about 555 m above sea level, which means the roofs of restaurants here face strong sun, wide daily temperature swings and dry air, and a roof that works well in a coastal city may need a different approach. Before any quote is made, the technician begins by checking the roof surface itself, looking for cracks, ponding and the condition of any existing coating. Liquid roof waterproofing typically falls in the range of SAR 8–25 per m², while bitumen membrane sits at SAR 15–35 per m², so the surface condition often decides which system suits the roof and budget. Where cracks are found, crack injection at SAR 40–120 per metre may be needed before any coating goes on.

Some points can only be settled on site. The technician will measure the roof area directly, since prices are quoted per square metre and the true area drives the final figure. They will also check the slope, the drainage outlets and the parapets, along with any rooftop equipment such as extraction units and air-conditioning plant that must be worked around. Whether a restaurant also needs spray foam at SAR 20–45 per m² or XPS boards at SAR 12–30 per m² for insulation depends on how the roof is used and how hot the kitchen area below runs, and that is judged by eye and by measurement rather than from a desk.

To help the technician arrive prepared, the restaurant manager can note when leaks have appeared, whether they follow rain or occur during hot afternoons, and which areas of the roof are walked on for deliveries or maintenance. It also helps to share any previous waterproofing records, the age of the building, and whether a water tank is located on the roof, since tank internal coating is priced at SAR 25–60 per m² and is handled separately. Keeping access to the roof clear and telling the team about any kitchen operating hours that affect working times will allow the visit to run smoothly and the scope to be agreed without delay.

For restaurants, visits are planned outside service hours and recorded for the premises file.
