Roof thermal insulation for schools in Alula
In short: In Alula (Alula), roof thermal insulation for schools begins with the roof, falls and drains survey and the thermal camera; nothing is opened until the position is clear. The centre of Alula sits about 697 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.
What is specific about Alula for roof thermal insulation
Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).
Alula sits about 697 m above sea level, which means its days can be sharply warm and its nights noticeably cooler than in the coastal cities. For school roofs, that daily swing matters. Heat builds through the roof slab during the afternoon and releases into classrooms long after the bell, so insulation is not a luxury here but a way to keep teaching spaces usable for longer in the day.
Each feature of the area translates into a practical rule for the work. Because the centre of Alula sits about 697 m above sea level, the work plan should account for a cooler night-time base and a strong afternoon heat load, so the insulation layer is sized to slow heat gain rather than just reflect surface warmth. The price band for XPS boards, SAR 12–30 per m², reflects a rigid, moisture-tolerant product that suits flat school roofs where the insulation sits beneath the waterproofing. Where the roof is exposed and the surface needs protection from sun and grit, liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are the usual companion layers, and the choice between them depends on the condition of the existing slab and the access the school allows during term time.
Owners tend to avoid a few predictable errors. They do not treat the roof as a single surface, so they skip the joints and parapet edges where heat and water most often get through. They do not ask for the insulation and waterproofing to be scheduled together, which leaves a finished layer exposed to dust and rain. They also avoid the temptation to compare quotes only by the lowest per-square-metre figure, since surface preparation and the sealing of cracks, quoted separately at SAR 40–120 per metre, can change the real cost. Planning these details early keeps classrooms cooler and the roof sound for years.
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
Where the problem usually comes from
- A common cause: no thermal insulation under the roof protection.
- A common cause: old insulation that has deteriorated.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Alula |
|---|---|---|
| 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 |
How the work is done, step by step
- 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.

Questions from Alula
What is the first step of roof thermal insulation for schools?
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 Alula?
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.
What we advise against
- Relying on reflective paint alone on an uninsulated roof
The written outputs
The written output: the documented thickness, materials and batch numbers. The report is numbered and can be checked with its verification code.
If you live in Alula and are new to the area
- 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).
