Roof rain leak emergency in Alrass: preventive periodic check

Before we start: what we know about Alrass

Team note on Alrass: 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 Alrass sits about 695 m above sea level (SRTM open elevation data).

Main roads in or near Alrass: King Abdulaziz Road, King Fahd Road, King Salman Road.

Roof leaks in Alrass most often start at the points where the waterproofing layer is interrupted: around parapets, drainage outlets, rooftop water tanks and the edges where the membrane meets walls. Over time the surface cracks or lifts, and water finds its way into the slab and then into the rooms below. Liquid roof waterproofing, typically priced between SAR 8 and SAR 25 per m², is the most common repair method for this kind of surface, and a periodic check usually catches the early signs before the damage reaches the ceiling.

Local conditions shape how that check should be done. The centre of Alrass sits about 695 m above sea level, so the site is well inland and the roof is exposed to strong daytime heat followed by cooler nights. That temperature swing makes the surface expand and contract, which is why hairline cracks often appear first on the roof and around the joints. An inspection here should look closely at expansion joints and the junctions with parapets, and should not rely only on the flat surface. Where a bitumen membrane is already in place, priced at SAR 15–35 per m², the technician should check whether it has blistered or separated at the edges. Where cracks are found, crack injection at SAR 40–120 per metre can seal the line before a full recoat is needed, and a rooftop water tank with a leaking base may call for tank internal coating at SAR 25–60 per m².

Before the visit, ask the provider to confirm exactly what will be inspected and whether the roof, parapets, drainage outlets and tank will be covered in one visit. Ask which materials they propose and how each is priced, using the per-square-metre or per-metre rates, so you can compare the quote against the ranges above. Ask whether the inspection will include a written note of any cracks, their locations and photographs, and whether they will explain the options before any work starts. Finally, ask how soon a follow-up check should be scheduled, so that small problems found now do not become ceiling leaks later.

Preventive checks follow a written schedule instead of waiting for a fault.

Signs worth paying attention to

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

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

Where the problem usually comes from

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

How we choose the tool in Alrass

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.
