What is specific about Rastanura for roof waterproofing

Team note on Rastanura: 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.. Rastanura is about 0.2 km from the sea coast (OpenStreetMap).

Roof leaks in Rastanura most often start at the joints and upstands rather than in the open field of the roof. Where the membrane meets a parapet, a drain, or a rooftop water tank stand, the sealant ages, lifts and lets water find a path under the surface. By the time a stain appears on a ceiling below, the damp has usually been travelling for some time, so checking these junctions first is the sensible starting point for any inspection.

The location changes how we approach the work. Rastanura sits about 0.2 km from the sea coast (OpenStreetMap), which means roofs here are exposed to salt-laden air that attacks metal fixings, sealants and the surface of many coatings more quickly than inland. Our approach therefore favours materials and details that tolerate salt and heat: liquid roof waterproofing at SAR 8–25 per m² is often a practical choice for open roof areas, while a bitumen membrane at SAR 15–35 per m² can suit roofs that see heavier foot traffic or need a thicker, more durable skin. Where a roof sits above a rooftop tank, the internal tank coating at SAR 25–60 per m² is a separate job and should be priced on its own. Insulation boards such as XPS at SAR 12–30 per m² may also be worth discussing if thermal performance matters alongside water resistance.

Before the visit, it helps to have a few details ready so the assessment is useful from the start. Tell us the roof's approximate area in square metres, whether it is accessible and used, how old the existing membrane is, and where you have seen water appear. Ask for a written breakdown that shows each item and its rate per m² or per metre, so you can compare it against the ranges above. Ask, too, how the proposed system will be prepared and tested before any coating goes on, and what will be covered in the scope of work. Clear answers to these questions will tell you far more about the quality of the job than any headline claim.

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

When do you need roof waterproofing?

These are the signs most often linked to roof waterproofing:

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

Where the problem usually comes from

• A common cause: cracks in the roof slab.
• A common cause: wrong falls towards the drains.
• A common cause: damaged waterproofing around tank and AC bases.

Tools and methods, and when we use them

The steps in order

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.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
