Roof thermal insulation in Alula: before summer & rain season
In short: In Alula (Alula), roof thermal insulation (before summer & rain season) 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
The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.
Picture a family who owns a single-storey house in Alula, with a flat concrete roof that bakes under the afternoon sun for much of the year. In the hotter months the rooms below feel stuffy even with the air conditioning running, and the electricity bills climb. When the short but heavy rain season arrives, they worry about water finding its way through the slab and into the ceilings. They want to protect the home before the next summer and before the next storm, without guessing at what the work should cost.
The local facts shape how they should think about this. The centre of Alula sits about 697 m above sea level, so the town is higher than the surrounding desert floor and sees a wider daily swing between hot afternoons and cooler nights. A roof that absorbs heat during the day releases it slowly into the rooms below, which is why insulation matters here. For the roof itself, the options range from liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m², to XPS boards at SAR 12–30 per m² and spray foam at SAR 20–45 per m². Each option covers a different need, so the owner should decide whether the priority is keeping heat out, keeping water out, or both.
A sensible sequence starts with a close inspection of the roof surface, looking for cracks, blistered coatings and any water stains on the ceilings beneath. Any crack should be treated first, since crack injection runs SAR 40–120 per metre and stops leaks at the source. Next, the owner should choose the insulation approach that suits the roof and the budget, then confirm the quantities by measuring the roof area in square metres so that the quote can be checked line by line. Finally, the work should be scheduled outside the peak heat of the day and well ahead of the rain season, so the coating has time to cure and the owner can check the result after the first storm.
Checks before summer and before the rain season catch problems while they are still small.
When do you need 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
Where the problem usually comes from
- A common cause: old insulation that has deteriorated.
- No thermal insulation under the roof protection.
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 |
| 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.

Questions from Alula
What is the first step of roof thermal insulation (before summer & rain season)?
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
What you get after the work
The written output: the documented thickness, materials and batch numbers. The report is numbered and can be checked with its verification code.
Planning the visit in Alula
- 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.
- 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.
