Why roof thermal insulation differs in Aljumum

Team note on Aljumum: 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 Aljumum sits about 200 m above sea level (SRTM open elevation data).

Roof thermal insulation for schools in Aljumum usually runs into the same problem: flat school roofs take the full force of the afternoon sun, and classrooms underneath heat up long before the day's lessons begin. Heat passes through a bare or poorly protected slab into the ceilings and then into the rooms, which makes air conditioning work harder and leaves children and staff uncomfortable during the hottest hours. Good insulation addresses this at the source, but the right system depends on how the roof is built and how it is used.

Aljumum sits at the centre of the local area at about 200 m above sea level, which means the site is not in a low coastal strip where humidity and salt air dominate, but it still faces strong daytime sun, wide temperature swings between day and night, and the dust that settles on exposed roofs. For schools this matters because roofs often carry play areas, drainage outlets and rooftop plant. Our approach here starts with the existing slab and any signs of old leaks or cracking, so that insulation does not trap moisture underneath. Materials are then matched to the roof: XPS boards are a common choice for their steady performance under foot traffic and sun, while liquid roof waterproofing and bitumen membrane can be added to protect the insulation from water and UV exposure.

Before the visit, ask the school or facilities team for the roof plan, any previous waterproofing or repair records, and details of which areas are used by students. Ask whether the roof is occupied during term, when work can be scheduled, and who will be responsible for access and safety during the job. It also helps to note which classrooms overheat most, since this guides where insulation will have the biggest effect. Prepare a list of visible leaks or damp patches and photograph them. A clear picture of the roof before the visit allows us to give a realistic scope and avoid surprises once work begins.

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

When do you need roof thermal insulation?

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

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

The most common causes

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

How we choose the tool in Aljumum

From the first visit to the report

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.
