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).

Does a hotel or serviced apartment building in Alqunfudhah really need a bitumen membrane, and what does it cost? The town centre sits about 7 m above sea level, and it is roughly 0.4 km from the sea coast, so the building is close enough to the coast that moisture and salt-laden air are a real concern for roofs and below-grade areas. A bitumen membrane is one of the waterproofing options used for these surfaces, and its typical cost for this work is SAR 15–35 per m². Because the price depends on the area and the condition of the surface, a site visit is the only reliable way to confirm the figure for your property.

Before any work is quoted, the inspection walks the roof and other sealed surfaces to check the existing condition. The inspector looks for cracks, blistering, ponding water and failed joints, and notes where the old material has lifted or worn thin. Where cracks are present, the cost of injecting them is measured separately, typically SAR 40–120 per metre, so each crack length is recorded. The inspector also measures the area of each section in square metres so the membrane can be priced per m², and checks the drainage outlets to see whether water is being held where it should run off. The result is a written scope that shows which areas need membrane and which need other treatment.

To make the visit efficient, gather the building's basic records before the inspector arrives. Have the roof plans or a sketch with dimensions ready, and list any areas that have leaked in the past, including the dates and locations if you know them. Note the age of the existing waterproofing and any previous repairs, and make sure access keys for the roof, plant rooms and basements are available. Clear the roof of loose items and tell the inspector if guests or staff use any part of the roof, so the work can be planned around normal operation. Good preparation shortens the visit and gives you a clearer quote to compare.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
