Roof thermal insulation for schools in Aldarb
In short: Roof thermal insulation for schools in Aldarb starts with the roof, falls and drains survey, then the thermal camera, before anything is opened. The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Pricing starts from Spray foam (per m²) (SAR 20–45 per m²), and other items are quoted after the visit.
Before we start: what we know about Aldarb
The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Aldarb is about 18.7 km from the sea coast (OpenStreetMap).
A school principal in Aldarb is responsible for a building that gets hot under the sun for much of the year, and the roof is usually the largest surface taking that heat. Classrooms below an uninsulated roof can become uncomfortable during the day, which affects concentration and pushes the cooling system to work harder. The owner's goal is simple: keep the rooms cooler, lower energy use, and protect the roof structure from heat damage over time.
The local facts shape how this plan should be read. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast. Both points mean the site is inland and not right on the coast, so the owner should focus on heat load from the sun rather than the salt-driven wear common to coastal buildings. Insulation that reduces heat passing through the roof deck is the main priority here, and the roof surface itself should be checked for cracks and ponding water so the insulation stays dry and effective.
A practical sequence starts with a roof inspection to identify cracks, failed joints, and areas holding water. Next, repair any cracks, since crack injection is priced per metre and is best done before new layers go on. After that, choose the insulation layer: XPS boards are typically priced per m² and suit a dry, insulated roof build-up, while liquid roof waterproofing and bitumen membrane can be used to seal the surface. Where the roof is flat and exposed, a spray foam layer is another option to compare on cost per m². Finally, ask each contractor to quote per m² for the full area so the school can compare like for like, and schedule works during school holidays to avoid disrupting classes.
For schools, the larger jobs are planned for weekends and holidays.
Signs that call for roof thermal insulation
These are the signs most often linked to roof thermal insulation:
- Strong heat on the top floor
- The AC runs for long hours in summer
- The ceiling stays hot at night
Causes we see in the field
- A common cause: old insulation that has deteriorated.
- No thermal insulation under the roof protection.
Tools we use in Aldarb
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
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.

Planning the visit in Aldarb
- 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).
- 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.
