Roof thermal insulation in Dhahran: the local context

The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data). Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Team note on Dhahran: 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..

A school administrator in Dhahran is usually responsible for a building that takes a lot of sun for much of the year. Classrooms under a flat roof can become hot in the afternoon, and the heat travels down through the ceiling into rooms where children are trying to learn. The administrator wants the roof to stay comfortable without running air conditioning at full strength all day, and wants any work to be planned around school terms rather than disrupting lessons.

The local facts shape that planning. Dhahran sits about 16 m above sea level and roughly 5.9 km from the coast, so the site is close enough to the Gulf to feel its humid air but not so exposed that salt is the main concern. For a school roof, the practical issues are intense solar heat on the roof surface and the need for a durable, sealed layer that can handle temperature swings. Insulation boards such as XPS are priced in the range of SAR 12–30 per m², while bitumen membrane sits at SAR 15–35 per m² and liquid roof waterproofing at SAR 8–25 per m². Comparing these options helps the owner match the layers to both the heat load and the budget.

A sensible order of work starts with a roof survey. Look for cracks, ponding water, and areas where the old covering has lifted, and mark any cracks for injection, which is priced at SAR 40–120 per metre. Next, decide the roof build-up: clean and repair the deck, then fit the insulation layer, then the waterproofing layer on top, so the heat barrier and the water barrier each do their job. Confirm the final quantities with the contractor by measuring the roof area in square metres, and ask for a written quote that lists each layer separately. Finally, schedule the work for school holidays, keep the site fenced off, and check the completed roof for leaks after the first rain.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to

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

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

Causes we see in the field

• Old insulation that has deteriorated.
• No thermal insulation under the roof protection.

Tools we use in Dhahran

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.
