Before we start: what we know about Jazan

Team note on Jazan: 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.. Jazan is about 1.9 km from the sea coast (OpenStreetMap).

The centre of Jazan sits about 7 m above sea level (SRTM open elevation data).

Is a roof leak after heavy rain an emergency, and what should a property owner in Jazan do first? Jazan sits about 7 m above sea level, and the city is about 1.9 km from the sea coast. Those facts matter for a roof leak because water that finds its way into a building does not drain away on its own, and a salt-laden coastal climate is hard on sealants and membranes. A leak that appears during or just after rain should be treated as urgent, since water left inside a structure can spread to ceilings, walls and electrical fittings quickly.

When a visit is arranged, the inspection usually starts with the roof surface itself, looking for cracks, lifted edges and failed joints where water is entering. The technician then checks the areas below the leak, such as ceilings, walls and any upper-floor bathroom that drains through the roof slab, to confirm where the water is actually coming from. Where a roof is flat and exposed, the options discussed for repair include liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m², while cracks are sealed by crack injection at SAR 40–120 per m. The final method depends on what the inspection shows, and the price range is given only as a general guide.

Before the visit, gather the information that will speed up the work: the building address in Jazan, a note of when the leak occurs and how heavy the rain was, photographs of any stains or drips, and access to the roof and the rooms below. Clear the area beneath the leak and move furniture and electrical items away from the water. If a bathroom sits directly above the affected area, mention it, because bathroom waterproofing is priced separately at SAR 15–40 per m². Having this ready helps the inspection find the source faster and keeps the repair focused on the leak itself.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs worth paying attention to

If you notice one of these signs in Jazan, it is a good moment to talk to the team:

• A stain growing on the top-floor ceiling
• Water standing on the roof that does not drain
• Drips from the ceiling during rain

Causes we see in the field

• Damaged waterproofing at the edges — we check this before anything else.
• A blocked roof drain — we check this before anything else.
• A split in the waterproofing around a tank or AC base.

How we choose the tool in Jazan

From the first visit to the report

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.
