Roof waterproofing in Sharurah: the local context

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.

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..

Picture the owner of a commercial building in Sharurah, perhaps a small office block or a warehouse with a flat roof, who wants the roof kept dry without disrupting staff every time rain arrives. Their concern is rarely the cost of a single repair; it is the uncertainty of when the next leak will appear and whether it will damage stock, equipment or the ceilings below. An annual contract suits this owner because it spreads the work across the year and gives one point of contact for inspections and minor fixes.

The central fact for this owner is altitude. The centre of Sharurah sits about 724 m above sea level, which places the town on a high plateau where the air is cooler than on the coast but the sun remains intense during the day. Roof surfaces therefore cycle between heat and cooling, and that movement can open hairline cracks over time. For a company, this means the roof should be checked for surface wear regularly rather than only after a leak appears. Liquid roof waterproofing typically costs SAR 8–25 per m², while a bitumen membrane sits at SAR 15–35 per m², so the choice of system should reflect how the roof is used and how often it is walked on.

For the practical steps, begin with a survey of the roof, noting ponding areas, cracks, and the condition of drains and upstands. Next, agree the scope in the annual contract, listing which systems will be used, such as crack injection at SAR 40–120 per metre for isolated splits or XPS boards at SAR 12–30 per m² where insulation is also needed. Then schedule the work outside peak operating hours and keep a written record of each inspection. Finally, review the contract each year against the roof's condition, adjusting the mix of repairs and coatings so the building stays protected without unplanned downtime.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs that call for roof waterproofing

The following signs are worth checking before they grow:

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

Where the problem usually comes from

• A common cause: damaged waterproofing around tank and AC bases.
• 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.
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.
