Why roof waterproofing differs in Alqunfudhah

Team note on Alqunfudhah: 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 Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Roof leaks are the most common problem with flat roofs in Alqunfudhah, and they usually show up first as damp patches on ceilings near parapets, drains and roof penetrations. Left alone, the water finds its way into the slab and the walls below, so the earlier the issue is caught, the simpler the repair. For most homes, the realistic options are liquid roof waterproofing, which costs SAR 8–25 per m², or a bitumen membrane, which costs SAR 15–35 per m². The right choice depends on the roof's condition and how much movement it sees.

Location matters here. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. That closeness to the coast means salt-laden air is present, which can speed up deterioration of surface coatings and metal fixings, so the installer should check the condition of railings, drain outlets and exposed fixings as part of the job rather than only the membrane itself. The modest elevation also means that rainwater has less natural fall to carry it away, so drainage outlets and falls on the roof need careful review. The approach taken for a roof here is therefore not a copy of a generic plan: the surface must be cleaned of salt and loose material, low points must be checked for ponding, and the chosen coating must be compatible with the substrate underneath.

Before the visit, ask the provider to confirm which system they propose and why, and to put the per m² rate in writing so you can compare it with the ranges above. Ask whether the price includes surface preparation, repairs to cracks, and any work on drains or parapet edges, because cracks are often billed separately at SAR 40–120 per metre. Ask how the roof will be inspected for ponding and drainage, how long the work is expected to take, and what the provider will do if the leak returns. Finally, ask to see photos of similar past work on flat roofs in the area. A clear written answer to these questions tells you far more than a sales pitch.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

The most common causes

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