Before we start: what we know about Yanbu

Main roads in or near Yanbu: King Abdulaziz Road, Umluj Road, Al Hanan Street. Team note on Yanbu: 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..

Yanbu is about 1.2 km from the sea coast (OpenStreetMap). The centre of Yanbu sits about 6 m above sea level (SRTM open elevation data).

An owner of a hotel or serviced apartment building in Yanbu usually has a lot to protect at once: rooftop plant areas, terraces, podium decks, and the roof slabs above guest floors. Guests notice a damp ceiling or a stained wall long before a leak reaches the structure, so the owner's real concern is keeping rooms dry and occupied without long closures. Many owners of this type of property also manage a tight budget and want one clear plan rather than a series of emergency repairs.

The local facts matter here. The centre of Yanbu sits about 6 m above sea level, which means the land is low and rainwater has to drain away quickly from roofs and terraces. Yanbu is also about 1.2 km from the sea coast, so the salty, humid air is close by and can speed up wear on exposed surfaces. For a bitumen membrane, this points to a fully bonded, well-sealed system on flat roofs, with attention paid to upstands, drains and edges where water tends to collect. Bitumen membrane typically costs SAR 15–35 per m², which makes it a sensible option for large roof areas, while smaller wet zones such as bathrooms need their own treatment at SAR 15–40 per m².

In practice, the owner should begin with a survey of the roof and any terraces, marking cracks, blocked outlets and areas of ponding. Next, decide which surfaces get the bitumen membrane and which need a different product, such as liquid roof waterproofing at SAR 8–25 per m² for lighter areas or spray foam at SAR 20–45 per m² for complex shapes. Repair any cracks first, since crack injection is priced per metre at SAR 40–120 per m, and make sure the substrate is clean and dry before the membrane goes down. Then plan the work in sections so guest rooms below stay usable, and finish with a water test and a written maintenance schedule so the building stays protected for years.

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