Roof waterproofing in Abu Arish: the local context

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).

Before any quote is given for a roof in Abu Arish, the technician starts by looking at the roof's general condition and how water is currently moving across it. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), which means the ground does not hold rainwater in the way low coastal flats might, so the first question is usually where water sits after a storm and which drains are blocked. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while bitumen membrane runs at SAR 15–35 per m², so the choice between systems depends on what the roof has already been through and how much movement it shows.

Several things are left to the site visit and cannot be settled from a desk. The technician must walk the roof, measure the true area, and check for cracks, bubbling, and failed old coatings. Crack injection is priced at SAR 40–120 per metre, so the length and depth of each crack can only be confirmed on the roof itself. Where water has reached the apartment below, the visit also covers whether the leak comes from the roof or from a bathroom above, since bathroom waterproofing is a separate job at SAR 15–40 per m². Insulation needs are judged on site too, and XPS boards at SAR 12–30 per m² are only specified once the surface is known to be sound.

To help the technician arrive prepared, residents should note where leaks have appeared inside the flat, how long after rain they show, and whether any water storage tank sits on the roof. A tank that needs internal work is priced separately at SAR 25–60 per m², and a tank can change the access arrangement on the day. Please also mention any previous roof repairs, the date of the last coating if known, and whether the building has a shared roof or separate roof areas for each unit. Clear answers to these points let the visit focus on the roof itself rather than on questions that could have been answered in advance.

In apartment buildings, the floor below is often where a leak shows first.

Signs that call for roof waterproofing

Causes we see in the field

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