Roof thermal insulation in Arar: before summer & rain season
In short: Roof thermal insulation (before summer & rain season) in Arar starts with the roof, falls and drains survey, then the thermal camera, before anything is opened. The centre of Arar sits about 553 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 Arar
The centre of Arar sits about 553 m above sea level (SRTM open elevation data).
The centre of Arar sits about 553 m above sea level (SRTM open elevation data), which places the town on high northern desert ground where summer heat is intense during the day and nights can turn noticeably cooler. Before anything else is planned for a roof here, the first check is the state of the existing surface and how it has handled the last heat season. Technicians look for hairline cracks in the screed, lifted edges at parapets, and any sign that the roof holds water after a shower. Because the roof takes the full force of direct sun for many hours, the thermal layer and the waterproofing beneath it are checked together, so that one does not hide faults in the other.
Several things are left to the site visit because they can only be judged on the actual roof. These include the slope and whether ponding occurs, the condition of drains and outlets, the presence of old bitumen or liquid layers that may need removal, the number of penetrations such as water tanks, satellite fixings and ventilation pipes, and the way the roof meets the walls. Prices depend on the type of system chosen, and the ranges in the reference list are only a starting guide. Liquid roof waterproofing typically falls between SAR 8 and SAR 25 per m², a bitumen membrane between SAR 15 and SAR 35 per m², and XPS boards between SAR 12 and SAR 30 per m². The final figure is set only after measuring the area and confirming which layers are needed.
To help the technician prepare, it is useful to share a few details in advance. Note when the roof last leaked, whether the leak appeared during summer heat or during rain, and where any staining shows on the ceiling below. Mention whether the roof is used for water storage, a terrace, or equipment, since foot traffic and weight affect the choice of layers. If there is a water tank on the roof, say whether it has been coated internally, because tank coatings are priced separately, between SAR 25 and SAR 60 per m². Clear notes on these points let the visit focus on the problem areas and reduce time spent on guesswork.
Checks before summer and before the rain season catch problems while they are still small.
Signs worth paying attention to
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
Causes we see in the field
- No thermal insulation under the roof protection.
- A common cause: old insulation that has deteriorated.
Tools and methods, and when we use them
| 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 |
| 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.

Short answers for Arar
Where does roof thermal insulation (before summer & rain season) start in Arar?
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).
What does roof thermal insulation cost in Arar?
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 receive after the work?
The documented thickness, materials and batch numbers, in a technical report that carries a verification code.

Practical notes for residents of Arar
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- 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.
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
