Before we start: what we know about Ahad Almasarihah

Team note on Ahad Almasarihah: 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 Ahad Almasarihah sits about 667 m above sea level (SRTM open elevation data).

Picture a family who owns a rest house on a farm just outside town. Each winter they notice damp patches spreading across the ceiling of the upper room, and every summer the flat roof bakes until the old coating cracks. They want the problem solved once, without paying twice, and they want to understand what the work will actually cost before anyone climbs a ladder. Many owners in this position are not in the country year-round, so they also need a plan that holds up while the property sits empty for weeks at a time.

The centre of Ahad Almasarihah sits about 667 m above sea level, which matters for roofs in ways that flat-land guides rarely mention. Higher ground tends to mean more exposure to wind and to the temperature swings between hot afternoons and cooler evenings, and both stress the joints where a roof meets a parapet or a water tank stand. For a rest house or farm building, that means the first job is to look closely at those edges and at any cracks rather than assuming the main field of the roof is the only problem. Liquid roof waterproofing typically falls in the range of SAR 8–25 per m², bitumen membrane SAR 15–35 per m², and spray foam SAR 20–45 per m², so the choice of system should follow the condition of the surface and how much movement it carries, not only the price per square metre.

A sensible sequence starts with a dry, clean surface and a written list of every crack, drain outlet and upstand. Crack injection is usually priced per metre, at SAR 40–120 per m, and should be completed before any membrane or coating goes on. If the building has a water tank on the roof, its internal coating, at SAR 25–60 per m², should be treated as part of the same job so the water you drink is protected as well. Where insulation is wanted, XPS boards at SAR 12–30 per m² can be laid beneath a protective layer. Finally, allow the materials to cure fully, check the finish after the first heavy rain, and keep a simple record of the work so the next owner or caretaker knows exactly what was done and when.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need roof waterproofing?

If you notice one of these signs in Ahad Almasarihah, it is a good moment to talk to the team:

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

Where the problem usually comes from

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