Roof rain leak emergency in Alrass: the local context

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

The centre of Alrass sits about 695 m above sea level (SRTM open elevation data).

Roof leaks in Alrass are usually first assessed by looking at where the water enters and how it travels, before any material is chosen. Alrass sits at about 695 m above sea level, which puts it on high ground in the Riyadh region, so the first checks focus on roof surfaces, parapets, drainage outlets and the junctions where the roof meets walls and rooftop fixtures. Technicians look at ponding areas and blocked outlets because water that stands on a flat roof has more time to find a path through small gaps. Ceiling stains, damp patches on upper walls and any cracking in the roof screed are noted early, since these show the likely entry point.

Several things are left to the site visit because they cannot be judged from a description alone. The exact condition of the existing membrane, whether the substrate is sound, how much of the roof is affected and whether the leak comes from a crack, a failed joint or a pipe penetration all need to be inspected on the roof and in the rooms below. Cost depends on the area treated and the system chosen. For reference, liquid roof waterproofing is typically priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m². Crack injection is priced separately at SAR 40–120 per metre, so a localised crack repair may suit the job better than recoating a whole roof. The technician will recommend the option that fits the findings on the day.

To help the technician arrive prepared, please note when the leak appears, whether it follows heavy rain, and which room or ceiling area is affected. Photographs of stains, any previous repair work and the age of the roof covering are useful. Clear access to the roof hatch and the rooms below will speed up the visit. Please also tell us if there is standing water on the roof after rain, and whether any rooftop tanks, air conditioning units or satellite fixtures sit near the damp area, since these can be the source of leaks that look like roof faults.

The aim is to locate the cause with instruments first, so any opening is limited to one point.
