Roof thermal insulation in Alaridah: with a verifiable technical report
In short: Roof thermal insulation (with a verifiable technical report) in Alaridah starts with the roof, falls and drains survey, then the thermal camera, before anything is opened. The centre of Alaridah sits about 2591 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.
What is specific about Alaridah for roof thermal insulation
The centre of Alaridah sits about 2591 m above sea level (SRTM open elevation data).
The centre of Alaridah sits about 2591 m above sea level, according to SRTM open elevation data, and that height shapes what a technician looks at first on a roof. At this elevation the sun and temperature swings are strong, so the first check is the roof surface and the membrane or insulation already in place. Before any product is discussed, the technician should confirm which roof system is present, whether it is a liquid roof waterproofing layer, a bitumen membrane, or an XPS board layer, because the work and its cost differ. Liquid roof waterproofing typically falls in the range of SAR 8–25 per m², bitumen membrane in the range of SAR 15–35 per m², and XPS boards in the range of SAR 12–30 per m². Knowing the existing system helps the technician avoid quoting the wrong scope.
Other items are left to the site visit, because they cannot be judged from a description. The technician needs to see the actual condition of the roof: cracks, ponding areas, blistering, and the state of any parapets and drainage outlets. Crack injection is priced at SAR 40–120 per metre, so the length and depth of visible cracks matter, and only the technician can measure them in person. Access to the roof, the presence of water tanks, and whether the roof is used for other purposes also belong to the visit. If the tank is on the roof, tank internal coating at SAR 25–60 per m² may come into the discussion, but the condition of the tank interior is only seen on site.
Information that helps the technician prepare includes the roof area in square metres, the age of the building, any past leaks and where they appeared, and photos of the roof surface if the customer can supply them. It also helps to note whether the building has a basement or bathrooms on the roof level, since basement waterproofing at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², and spray foam at SAR 20–45 per m² are separate line items. Clear answers to these questions let the technician arrive ready, confirm the scope on the roof, and give the customer a written breakdown they can compare.
Each job ends with a written report that carries a verification code you can check on our site.
Signs that call for roof thermal insulation
The following signs are worth checking before they grow:
- The ceiling stays hot at night
- The AC runs for long hours in summer
- Strong heat on the top floor
Causes we see in the field
- A common cause: no thermal insulation under the roof protection.
- Old insulation that has deteriorated — we check this before anything else.
Tools we use in Alaridah
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
From the first visit to the report
- 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.
