Roof thermal insulation for restaurants in Aljumum
In short: In Aljumum (Aljumum), roof thermal insulation for restaurants begins with the roof, falls and drains survey and the thermal camera; nothing is opened until the position is clear. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data). Published price: Spray foam (per m²), SAR 20–45 per m²; anything else is quoted after the inspection.
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).
Restaurant roofs in Aljumum tend to suffer from heat gain rather than leaks alone. Kitchen exhaust, rooftop equipment and long opening hours all push heat into the building below, and the dining room and cold storage pay for it in higher cooling loads. Insulation is the usual fix, but the choice of material matters, because a roof that is hot, busy and exposed to foot traffic needs a surface that can take the load without breaking down.
Aljumum sits at about 200 m above sea level, so the site is not a high-altitude mountain town, yet it is still inland and exposed to strong daytime sun. The local facts shape the approach in a few practical ways. Liquid roof waterproofing is priced from SAR 8–25 per m², and bitumen membrane from SAR 15–35 per m², which gives a restaurant owner two clear options for the top layer. XPS boards, at SAR 12–30 per m², provide the thermal layer beneath. Spray foam, at SAR 20–45 per m², can be used where the roof shape makes boards difficult to fit. We match the layers to the roof's age, its slope, and whether the kitchen extraction ducts or plant units need to be worked around, rather than applying one system to every roof.
Before the visit, ask a few things so the survey is useful. Tell us which areas of the roof are regularly walked on, where the kitchen exhaust and air-conditioning units sit, and whether you have noticed damp patches on ceilings above the dining room or storage. Share the roof's approximate area in m², any previous coating or membrane, and whether you plan any changes to the kitchen layout. Those details let the site visit focus on the real heat and moisture problems, and they make the quotation easier to compare line by line.
For restaurants, visits are planned outside service hours and recorded for the premises file.
When do you need roof thermal insulation?
The following signs are worth checking before they grow:
- The AC runs for long hours in summer
- Strong heat on the top floor
- The ceiling stays hot at night
Causes we see in the field
- A common cause: no thermal insulation under the roof protection.
- Old insulation that has deteriorated.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Aljumum |
|---|---|---|
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
The steps in order
- Thermal survey: Hot areas of the roof are mapped.
- Choosing the system: The material and thickness are agreed in the quote.
- Installation: The layer is installed and protected.
- Measurement and documentation: Thickness is measured at spread-out points.

Common questions about roof thermal insulation in Aljumum
What is the first step of roof thermal insulation for restaurants?
We start with thermal survey (hot areas of the roof are mapped), then choosing the system (the material and thickness are agreed in the quote).
How much does roof thermal insulation cost in Aljumum?
From our published price list: Spray foam (per m²) SAR 20–45 per m²; XPS boards (per m²) SAR 12–30 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The documented thickness, materials and batch numbers, in a technical report that carries a verification code.
Common mistakes we see
- Relying on reflective paint alone on an uninsulated roof
What you receive
The written output: the documented thickness, materials and batch numbers. The report is numbered and can be checked with its verification code.
Practical notes for residents of Aljumum
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
