What is specific about Abu Arish for roof waterproofing

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). 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..

Does a roof in Abu Arish need waterproofing, and how do you know if yours does? The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), which places it on higher ground than the coastal flats, but elevation does not protect a roof from rain runoff, ponding, or the slow cracking caused by daily heat. The practical answer comes from inspection rather than assumption. Common signs include damp patches on ceilings below the roof, peeling or blistered surface coatings, visible cracks in the slab, and water pooling after a shower of rain. Liquid roof waterproofing typically costs SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m², so the choice of system depends on the roof's condition and how much it is exposed.

A proper inspection starts with a walk over the full roof surface to map cracks, joints, drainage outlets and the edges where the membrane meets parapets and pipes. Each crack is measured, since crack injection is priced per metre at SAR 40–120 per m, and the technician notes whether the damage is surface-level or runs through the slab. Next, the inspector checks the areas around water tanks and rooftop fixtures, where tank internal coating is priced at SAR 25–60 per m² if the tank itself needs treatment. Where insulation is part of the plan, XPS boards at SAR 12–30 per m² are considered for thermal performance. The inspector then records the findings and proposes a system matched to what was found, rather than a single product applied everywhere.

Before the visit, gather any earlier repair records, the date the current roof was built or last treated, and notes on leaks you have observed, including where they appear and after which kind of weather. Clear access to the roof and the water tanks, and make sure the stairs or hatch are safe to use. If you have photos of stains or cracks taken from below, keep them ready. Knowing the roof's history lets the inspector focus on the right problems from the start, which keeps the assessment accurate and the scope of work clear before any money is committed.

Each job ends with a written report that carries a verification code you can check on our site.
