Roof waterproofing in Tabarjal: the local context

The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). 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..

Will a clinic roof in Tabarjal really need waterproofing, and what will it cost? Tabarjal sits at about 548 m above sea level, and the roofs of clinics there are exposed to sun and weather that can wear down a surface over time. Most property owners ask first which method suits a flat roof and roughly what it will cost, so the answer starts with the options. Liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Spray foam, at SAR 20–45 per m², is another route for roof areas, and cracks found along the surface can be treated by crack injection at SAR 40–120 per m.

Before any work is quoted, the roof is inspected step by step. The surveyor first walks the full roof area to note ponding, blistering, and any cracks, then measures the surface so the quote can be calculated per square metre. Where cracks are present, their length is recorded in metres, since crack injection is priced by the metre. The surveyor also checks the parts of the building that connect to the roof, such as parapets, drains, and rooftop water tanks, because a leak often starts at a junction rather than in the open field of the roof. Where a water tank sits on the roof, its internal coating is checked separately, as tank internal coating is priced at SAR 25–60 per m².

To make the visit efficient, the owner should prepare a few things in advance. Clear access to the roof, including the stair or ladder route and the roof hatch, will save time. Any earlier waterproofing records, repair invoices, or drawings of the roof layout should be gathered so the inspector can see what was done before. It also helps to note where water has previously appeared inside the clinic, such as on ceilings or near walls, and to mention any work planned on the roof or the floors below. With these details ready, the inspection can move straight to measuring and comparing the options.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

• Stains on the top-floor ceiling after rain
• Water pooling on the roof
• The old waterproofing is cracking

Causes we see in the field

• Damaged waterproofing around tank and AC bases — we check this before anything else.
• Wrong falls towards the drains — we check this before anything else.
• A common cause: cracks in the roof slab.
