Before we start: what we know about Abu Arish

Team note on Abu Arish: 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 Abu Arish sits about 67 m above sea level (SRTM open elevation data).

Does a roof in Abu Arish need waterproofing before you buy or take over a property? In most cases, yes, and the answer depends on what the roof is made of and how it has been maintained. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), so the town is not a low-lying flood plain, but rain that arrives in short, heavy bursts still runs off roofs quickly and finds any weak point. Liquid roof waterproofing typically costs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², and XPS boards SAR 12–30 per m², so the cost of addressing a problem early is usually far lower than the cost of repairing water damage inside the building.

A proper inspection starts with the surface itself. Look for cracks, blistering, bare patches, and areas where the coating has lifted or pulled away from upstands and parapets. Check drainage outlets and make sure they are clear and sloping correctly, since standing water is the most common cause of early failure. Inspect the junctions where the roof meets walls, pipes, and roof hatches, because these are where leaks usually start. If there is a water tank on the roof, check its internal condition as well. Tank internal coating is priced at SAR 25–60 per m², and a tank that has been neglected can contaminate the water supply. Where cracks are visible, the repair method matters: crack injection is quoted at SAR 40–120 per metre, and the right approach depends on whether the crack is moving or stable.

Before the visit, gather whatever documents the seller or landlord can provide, including any previous waterproofing invoices, warranty papers, and records of roof repairs. Note any past leaks, stains on ceilings, or damp patches in the rooms below, and ask when the roof was last recoated. Clear access to the roof is essential, so arrange keys for the roof door and remove stored items that block the surface. If the property has a basement or bathrooms, mention them too, since basement waterproofing is quoted at SAR 50–150 per m² and bathroom waterproofing at SAR 15–40 per m², and the same contractor can often assess them during one visit. Preparing these details in advance lets the inspection focus on what matters and gives you a clear basis for negotiating price or repairs.

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