What is specific about Tabarjal for roof waterproofing

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 restaurant roof in Tabarjal need waterproofing, and what will it cost? The centre of Tabarjal sits about 548 m above sea level, and that open elevation data is a useful starting point for thinking about exposure. Whatever the altitude, a flat commercial roof carries heavy foot traffic, kitchen extraction equipment and daily water runoff, so the first question is usually which system suits the surface. For roofs, the figures we have are liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Liquid systems tend to be the lowest entry cost, while membranes and insulated boards suit roofs that need more protection or thermal performance.

A visit to inspect a restaurant roof usually starts with a walk over the full surface to find ponding areas, cracked screeds, lifted edges and the seals around vents, hoods and rooftop units. The inspector will check where water currently collects after rain and trace any staining on the ceiling below, since leaks often appear some distance from their source. Where a crack runs through the structure, crack injection is priced at SAR 40–120 per metre, and the inspector will measure its length so the scope can be sized accurately. Any problems in the kitchen or washroom areas below the roof are noted separately, because those rooms use different products, such as bathroom waterproofing at SAR 15–40 per m² or epoxy coating at SAR 35–90 per m² on floors that see grease and cleaning chemicals.

Before the visit, gather the roof plan or any drawings you have, and note the dates and locations of previous leaks or repairs. Clear the roof of loose items, grease containers and stored equipment where you can, so the inspector can reach the drain outlets and edges. Let your kitchen and front-of-house staff know when the visit is planned so that equipment on the roof can be switched off if needed. If you have a water tank on the roof, mention it in advance, since tank internal coating is priced at SAR 25–60 per m² and is handled as a separate item from the roof surface.

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

Signs worth paying attention to

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

The most common causes

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

From the first visit to the report

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
