Roof rain leak emergency for duplexes in Tabarjal

Before we start: what we know about Tabarjal

The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). Team note on Tabarjal: 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..

Picture a family who owns a duplex in Tabarjal, with two households sharing one roof. One evening a dark stain appears on a bedroom ceiling, and by morning water is dripping into a corner. Neither side of the building wants to be blamed, and each owner wonders whether the leak started upstairs or down. Situations like this are common, and the first hours matter more than the final repair.

The local facts shape what this means. The centre of Tabarjal sits about 548 m above sea level, so the town is not a low-lying flood plain, but it is still exposed to rain that arrives in short, heavy bursts that push water into any weak point on a flat roof. Because a duplex has a shared roof slab, water that enters one unit can travel along beams and into the other, so a fix on one side alone rarely solves the problem. Prices for roof work vary widely: liquid roof waterproofing typically falls between SAR 8 and SAR 25 per m², bitumen membrane between SAR 15 and SAR 35 per m², and XPS boards between SAR 12 and SAR 30 per m². Crack injection, which is often the right tool for a single leaking line, is priced between SAR 40 and SAR 120 per metre. Knowing these ranges helps owners compare quotes sensibly.

Start by moving furniture and placing a container under the drip, then photograph the stain and the water path so you have a record. Next, go onto the roof after the rain has stopped and look for cracked screed, lifted membrane edges, blocked drains and pooling water. Clear any debris from drain outlets and parapets so water can run away. Agree with the other owner in writing who will inspect the upper surface and who will cover the cost of shared sections. Then ask for at least two written quotes that state the area in m², the method and whether it is priced per m² or per metre, so the scope is clear. Finally, schedule the repair for dry weather and check the completed work with a test after the next rainfall.

In a duplex, the two floors often share lines, so tests are done floor by floor.
