Roof thermal insulation for schools in Alqurayyat
In short: Roof thermal insulation for schools in Alqurayyat starts with the roof, falls and drains survey, then the thermal camera, before anything is opened. The centre of Alqurayyat sits about 497 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 Alqurayyat: the local context
The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). Team note on Alqurayyat: 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..
The first thing checked on a school roof in Alqurayyat is the altitude, because the centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). That height means the site is not a low-lying hot basin, but it still receives strong sun for most of the year, so the roof surface takes heavy daytime heat load. Before anything else, the technician looks at the roof's exposure, its drainage slope, and whether the existing deck is sound enough to carry new insulation without trapping moisture underneath.
Several questions are left for the site visit itself, because they cannot be settled from a desk. The technician needs to see the actual condition of the roof deck, the edges and parapets, any ponding areas, and the spots where pipes, vents and rooftop units break through the surface. Costs for the main options are set out in the facts: liquid roof waterproofing runs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², spray foam SAR 20–45 per m², and XPS boards SAR 12–30 per m². Which of these fits a given roof depends on what is found on the day, so the choice is confirmed on site rather than assumed in advance. Where cracks are present, crack injection is priced at SAR 40–120 per metre, and that work is also scoped only after inspection.
Helpful information for the technician includes the school's roof area in square metres, the number of roof sections and their levels, whether any part is accessible for foot traffic or equipment, and when classes and activities use the building so that work can be planned around them. Note any previous repairs, leak history and the age of the existing finish. If a water tank sits on the roof, record it, since tank internal coating is separately priced at SAR 25–60 per m². Clear notes on these points let the technician arrive ready to measure, test and quote accurately.
For schools, the larger jobs are planned for weekends and holidays.
Signs worth paying attention to
The following signs are worth checking before they grow:
- The ceiling stays hot at night
- Strong heat on the top floor
- The AC runs for long hours in summer
Where the problem usually comes from
- Old insulation that has deteriorated.
- A common cause: no thermal insulation under the roof protection.
Tools we use in Alqurayyat
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
| 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.
