Before we start: what we know about Alqunfudhah

Team note on Alqunfudhah: 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 Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Bitumen membrane work on apartment buildings in Alqunfudhah most often starts with roof and terrace leaks, where water finds its way through worn joints and tired surfaces and then runs down into the flat below. Because the membrane is laid over the full roof area, the job is usually priced per square metre, with bitumen membrane at SAR 15–35 per m². Many residents only notice the problem once a ceiling stain appears, so a yearly look at the roof surface is a cheap habit that catches small faults before they spread.

The local setting shapes how the work is planned. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. That closeness to the coast means the surface is exposed to salty, humid air, so the membrane and its edges need careful preparation and sealing rather than a quick overlay. Where a roof has several levels or parapets, the installer should check every upturn and drain outlet, since these are the points where water tends to get under the sheet. The low elevation also means drainage matters: a roof that holds puddles after rain will age faster, so falls and outlets are checked before any new layer goes down.

Before the visit, ask the provider to confirm the roof area in square metres so the quote can be checked against the SAR 15–35 per m² range. Ask whether the price includes cleaning and repairing the existing surface, and how the edges and drain outlets will be treated. Find out which parts of the roof are shared with other flats and who should approve the work. It also helps to ask which other services in the building, such as a terrace or bathroom treatment, could be combined in the same visit to save disruption to residents.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
