Roof waterproofing in Sharurah: the local context

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Roof leaks in apartment buildings usually start at the junctions where the roof slab meets upstands, parapets, drain outlets and rooftop water tanks. Water finds these weak points, runs along the slab and appears as stains on the top-floor ceilings below, often long before the damage is visible from the outside. In Sharurah, the most frequent complaint from residents is a damp patch that returns after a rainy spell, which usually points to a failed membrane or a cracked seam rather than a single hole.

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data), and that altitude matters for how roofs are treated. Sites at this height see strong sun during the day and sharp temperature swings between day and night, which make the roof surface expand and contract. A liquid roof waterproofing system, priced in the range of SAR 8–25 per m², can flex with that movement, while a rigid finish is more likely to crack. A bitumen membrane, in the range of SAR 15–35 per m², is another common option where the roof must shed water quickly. For roofs that also carry a water tank, tank internal coating in the range of SAR 25–60 per m² may be needed alongside the roof work, and XPS boards at SAR 12–30 per m² can help where insulation is a concern. The right choice depends on what the roof actually does, not on the cheapest rate.

Before the visit, ask the service provider to confirm which area of the roof they will inspect and whether they will check the upstands, drains and tank base as well as the open slab. Ask how they will test for leaks, whether they will check the top-floor ceilings below for water tracks, and which material they propose and why it suits a roof at this altitude. Request a written scope that lists each part of the work and its unit price, so you can compare it with the ranges above. Finally, ask who will be responsible for access to the roof and for moving rooftop equipment, so the visit can happen without delay.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

Signs that call for roof waterproofing

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

How we choose the tool in Sharurah

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.
