Before we start: what we know about Aljumum
Team note on Aljumum: 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 rest house or small farm in Aljumum. The building is used at weekends and in holiday seasons, so it often sits empty for long stretches. Roof surfaces take the full force of sun by day and rain when it does fall, and a small leak that goes unnoticed for weeks can spread into ceilings, walls and stored equipment before anyone sees it. Owners of such properties usually want a roof treatment that is affordable, lasts through the seasons and can be repaired without emptying the whole building.
The local setting matters. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), so the site is well above the coast and the roof is exposed to open weather rather than sheltered low ground. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m² and XPS boards SAR 12–30 per m². For a flat rest-house roof, these are the main options to compare, and the choice depends on how much insulation and foot traffic the roof needs to handle.
Start by inspecting the roof after a rain, or with a hose test if it is dry, and mark every crack and ponding area. Crack injection is priced at SAR 40–120 per metre, so seal visible cracks before choosing a full surface system. Clean the surface, let it dry completely, and then apply the chosen coating or membrane in the correct layers, following the product's drying times. Check edges, drains and parapets, since these are where water most often enters. Finally, schedule a simple inspection each year before the rainy months, and note any new cracks so small repairs are made early rather than after water has reached the ceiling.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
Signs that call for roof waterproofing
The following signs are worth checking before they grow:
- The old waterproofing is cracking
- Water pooling on the roof
- Stains on the top-floor ceiling after rain
Causes we see in the field
- A common cause: cracks in the roof slab.
- A common cause: wrong falls towards the drains.
- Damaged waterproofing around tank and AC bases.
