Roof thermal insulation in Yanbu: the local context

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).

Picture the owner of a small restaurant in Yanbu who has just taken over a single-storey building with a flat roof. The kitchen runs hot through the afternoon, the dining room is hard to keep cool, and the energy bill climbs every summer. Like many owners in this position, they want the roof to do more of the work, but they are not sure where to start or what a sensible scope looks like for a building that serves customers every day.

The local setting matters. The centre of Yanbu sits about 6 m above sea level, and the city is about 1.2 km from the sea coast. That combination means a roof here faces strong sun and warm, humid air drifting in from the coast, so moisture and heat both need attention. For a restaurant, this means insulation and waterproofing should be planned together, because a roof that holds heat but lets water in will cause trouble in the kitchen extract area and the storage rooms below.

The practical steps are straightforward. First, inspect the roof surface and mark any cracks or ponding, since crack injection is priced per metre and is often the first job. Second, decide on the insulation layer; XPS boards are priced per m² and suit flat roofs well, while spray foam is an alternative where the surface is irregular. Third, choose a waterproofing layer such as liquid roof waterproofing or a bitumen membrane, comparing their per m² costs against the expected life of the roof. Fourth, if the building has a water tank on the roof, budget for tank internal coating separately, as it is priced on its own. Finally, arrange the work so that the kitchen can keep operating, starting with the quieter sections and leaving the extract area until last.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

These are the signs most often linked to roof thermal insulation:

• The ceiling stays hot at night
• The AC runs for long hours in summer
• Strong heat on the top floor

Causes we see in the field

• No thermal insulation under the roof protection — we check this before anything else.
• Old insulation that has deteriorated — we check this before anything else.

Tools and methods, and when we use them

How the work is done, step by step

1. Thermal survey: Hot areas of the roof are mapped.
2. Choosing the system: The material and thickness are agreed in the quote.
3. Installation: The layer is installed and protected.
4. Measurement and documentation: Thickness is measured at spread-out points.
