Roof thermal insulation for clinics in Aljumum

Before we start: what we know about 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 clinics in Aljumum faces a familiar problem: the roof slab takes the full afternoon sun, and the heat travels straight down into rooms where treatment equipment, cold storage and waiting patients all depend on a steady temperature. In a clinic, a warm ceiling space is more than an comfort issue. It can push air-conditioning to run hard for long hours, and it can leave treatment rooms harder to keep within the range the equipment needs. Most clinic roofs we assess have little or no insulation above the top floor, so the first step is always to measure the slab and look for the places where heat is entering fastest.

Aljumum's location shapes how that work is done. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), so the area is not at the coastal humidity level that drives some other Saudi cities, but strong sun on an exposed roof still drives heat gain through the day. Because the roof is the main route for heat into a clinic, the approach focuses on the roof surface and what sits beneath it. Options are priced by area: XPS boards (per m²): SAR 12–30 per m², spray foam (per m²): SAR 20–45 per m², and liquid roof waterproofing (per m²): SAR 8–25 per m². A roof often needs insulation and a waterproofing layer together, so the two are assessed side by side rather than as separate jobs, and a bitumen membrane (per m²): SAR 15–35 per m² may suit some flat roofs where a sealed layer is the priority.

Before the visit, it helps to have a few details ready. Share the roof area, the type of slab, whether there is an existing waterproofing layer, and which rooms sit directly below the roof, since treatment and storage rooms are usually the priority. Note any cracks, damp patches or past leaks, and tell us which floor is occupied and when the clinic is quietest, so work can be scheduled without disrupting patients. Ask how the proposed materials will be laid around parapets, drains and roof openings, and request a written scope that lists each layer and its area. That gives you a clear basis for comparing options before any work starts.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs that call for roof thermal insulation

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

Where the problem usually comes from

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

Tools and methods, and when we use them

The steps in order

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.
