Roof thermal insulation for duplexes in Aldiriyah
In short: Roof thermal insulation for duplexes in Aldiriyah starts with the roof, falls and drains survey, then the thermal camera, before anything is opened. The centre of Aldiriyah sits about 655 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.
Roof thermal insulation in Aldiriyah: the local context
The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data). Team note on Aldiriyah: 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..
In a duplex, the two floors often share lines, so tests are done floor by floor.
Signs worth paying attention to
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
The most common causes
- Old insulation that has deteriorated — we check this before anything else.
- No thermal insulation under the roof protection.
How we choose the tool in Aldiriyah
| Tool | What it finds | When we use it in Aldiriyah |
|---|---|---|
| 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 |
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 mistakes we see
- Relying on reflective paint alone on an uninsulated roof
What you receive
You receive: the documented thickness, materials and batch numbers, in a technical report with a verification code.
Planning the visit in Aldiriyah
- 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.
