Before we start: what we know about Jubail

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data). Jubail is about 0.9 km from the sea coast (OpenStreetMap).

Team note on Jubail: 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..

Jubail sits close to the Arabian Gulf, with the centre about 4 m above sea level and roughly 0.9 km from the sea coast. That combination matters for roofs. Low-lying coastal ground keeps moisture and salt-laden air around buildings, so roof membranes, flashings and drainage outlets see more humidity and salt exposure than they would further inland. When a leak appears in Jubail, the source is often a seam, upstand or drain that has been weathered by this environment rather than a single dramatic failure.

For an emergency visit, the practical effect is that the first task is to trace water back to its entry point, not just to stop the drip below. Technicians typically check the roof surface, outlets and parapet junctions, and any previous repairs, before choosing a fix. Liquid roof waterproofing is priced in the range of SAR 8–25 per m², and bitumen membrane runs SAR 15–35 per m², so the cost of a full roof system can differ widely from a localised patch. Where a crack is the cause, crack injection is charged per metre at SAR 40–120 per m, which is why an accurate measurement of the defect length is part of the assessment. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² may also be considered where insulation and waterproofing are being upgraded together.

Owners often make the same avoidable mistakes during a roof leak. Many wait until ceilings are stained before calling anyone, which lets water travel into insulation and fixtures. Others apply a surface sealant over a wet substrate, so the coating lifts within weeks. Some place buckets and walk away without clearing the drain outlets, which leaves standing water to find the next weak point. Finally, owners sometimes accept a quote without asking which layer is being repaired and why. Asking the technician to show the entry point, state the area or length involved, and explain the chosen material keeps the repair grounded in what the roof actually needs.

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

The following signs are worth checking before they grow:

• Drips from the ceiling during rain

Tools and methods, and when we use them

The steps in order

1. Protect what is below: Move belongings and contain the water first.
2. Drain the roof: Clear the roof drains so water can leave.
3. Inspection after the rain stops: The entry point is found on a dry roof.
4. Treatment: A local repair or a waterproofing plan, as the inspection shows.
