Roof thermal insulation in Aljumum: the local context

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).

Imagine an apartment owner in a multi-storey building who notices warm patches on the top-floor ceiling during the afternoon and a musty smell after rain. The roof is the part of the building that takes the most sun, and the heat it absorbs travels straight down into the flat below. Many owners in this situation postpone the problem until the cost of cooling rises or stains spread across the ceiling, when a simpler fix would have been available earlier.

Aljumum sits about 200 m above sea level, according to SRTM open elevation data. That height is a useful reminder that the area is not at coastal sea level, and it does not change the basic logic of roof protection: the roof still needs to shed water quickly and hold back heat. For apartment owners, the practical meaning is that the roof surface and the layers beneath it should be chosen for the conditions of the site rather than copied from a generic template. Roof insulation and waterproofing are usually planned together, because a membrane that keeps water out and an insulating layer that slows heat transfer both depend on a clean, sound surface.

A sensible sequence starts with inspection. Look for cracks, ponding water, and failed old coatings, and note any spots that feel warm or damp from inside. Next, repair the surface, filling cracks by injection where the lines are narrow and continuous. Then choose the layers: a liquid roof waterproofing system or a bitumen membrane for the water barrier, with XPS boards offering a rigid insulating layer where thermal performance matters most. Spray foam is another option for insulation where an even, seamless layer suits the roof shape. Finally, ask the contractor to confirm the scope in writing, including the area measured in square metres, so the quotation matches the work. Keep the record of what was done so future repairs are easier to plan.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

If you notice one of these signs in Aljumum, it is a good moment to talk to the team:

• 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.

Tools we use in Aljumum

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.
