Before we start: what we know about Rastanura

Rastanura is about 0.2 km from the sea coast (OpenStreetMap). 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..

Before any roof waterproofing work is bought or handed over in Rastanura, the first thing to check is the location itself. Rastanura is about 0.2 km from the sea coast (OpenStreetMap), which means roofs here sit close to salt-laden air and coastal humidity. That exposure matters because it shapes which surfaces deteriorate fastest and how quickly a poorly sealed area can begin to fail. Before comparing quotes, it helps to note that liquid roof waterproofing is typically priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m². Matching the system to the roof's condition, rather than choosing on price alone, is the sensible starting point.

Several points cannot be settled from a description or a photograph and are left to the site visit. The technician needs to see the actual condition of the roof surface, any cracks, the slope and drainage paths, the state of existing coatings, and the junctions with parapets, pipes and roof-mounted tanks. If a crack needs sealing, the length matters, because crack injection is priced at SAR 40–120 per metre. Where a rooftop water tank is involved, its internal coating is priced separately at SAR 25–60 per m², so it should be inspected and quoted on its own. Buyers and handover inspectors should also confirm which surfaces the contract covers, since bathroom waterproofing (SAR 15–40 per m²) and basement waterproofing (SAR 50–150 per m²) are different scopes and should not be mixed into a single roof figure.

To help the technician, prepare clear information before the visit. Note when leaks were first noticed and whether they appear after rain, during hot afternoons or at particular points on the roof. Share any earlier repair records, previous coating types and warranty papers, and mention whether thermal insulation such as XPS boards (SAR 12–30 per m²) is already installed. Point out access routes, roof hatch positions and any areas that are used for storage or equipment. Clear, specific details of this kind allow a more accurate assessment and a quote that reflects the real work, so the final scope can be agreed with fewer surprises.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

When do you need 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

Where the problem usually comes from

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

Tools and methods, and when we use them

How the work is done, step by step

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.
