Roof rain leak emergency in Aljumum: before buying or handover

Before we start: what we know about Aljumum

The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data). 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..

Aljumum sits in a hilly part of the Western Region, with the centre about 200 m above sea level (SRTM open elevation data). That height matters for roofs: higher ground means rain can run off quickly and hit exposed rooftops, parapets and roof edges with force, so water often finds its way through weak points rather than pooling evenly. For a rain leak emergency, the first check is usually the roof perimeter, drainage outlets and any cracks where water enters the building.

Because the leak is an emergency, it helps to know the typical cost ranges before you agree to any work. Liquid roof waterproofing is commonly SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m² and spray foam SAR 20–45 per m². Where a leak comes from a crack in a wall or slab, crack injection is priced at SAR 40–120 per metre, and if water is tracking down from a rooftop into a bathroom, bathroom waterproofing is SAR 15–40 per m². Knowing these ranges lets you compare quotes on a like-for-like basis, since a low price for a small patch may not cover a full roof area, and a high price for a single crack may not be justified.

Owners often make the same mistakes during a roof leak. They pay for a surface coat without first locating the source of the water, so the leak returns after the next storm. They accept a quote that does not state the coated area in m² or the length of cracks to be injected, which makes the final bill hard to check. They also delay the job until the leak spreads into ceilings, walls or stored items, when a quick repair would have cost far less. Before any handover, ask the contractor to show exactly where the water entered, confirm the materials used, and check that the roof edges and outlets have been included in the work.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
