Before we start: what we know about Almuzahimiyah

The centre of Almuzahimiyah sits about 889 m above sea level (SRTM open elevation data).

Roof thermal insulation for rest houses and farms in Almuzahimiyah starts with the place itself. The centre of Almuzahimiyah sits about 889 m above sea level, so the roof of a rest house or farm building here is exposed to conditions that differ from those on the coastal plain. On the first visit, the technician looks at the roof as it is: its slope, the surface material, any existing membrane, and the signs of heat or moisture that show where the roof is losing its protection. The starting point is the roof, not a price list, because the choice between insulation and waterproofing depends on what the roof is already doing.

Several things are left to the site visit, because they cannot be settled from a description. The technician measures the roof area and checks whether the slab is sound enough to take new layers. The team notes whether the roof drains properly, whether there are cracks that need to be injected, and whether water is already reaching the rooms below. The choice of material follows from these observations. Liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m². Where a roof also holds a water tank, the internal tank coating is priced at SAR 25–60 per m², and cracks are sealed by crack injection at SAR 40–120 per metre. The site visit decides which of these apply and in what combination.

Information that helps the technician is simple to gather in advance. Tell the team the roof's approximate area, how long the building has stood, and whether there have been leaks, damp patches or cracks after rain. Mention any tank on the roof and whether it has been drained and cleaned recently. Note whether the rooms beneath are used for sleeping or storage, since this affects how quickly any problem is noticed. A clear list of these points lets the technician arrive ready to measure and check, and it makes the written estimate easier to compare with the actual work needed on your roof.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need roof thermal insulation?

These are the signs most often linked to roof thermal insulation:

• 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

• No thermal insulation under the roof protection.
• A common cause: old insulation that has deteriorated.

Tools and methods, and when we use them

How the work is done, step by step

1. Thermal survey: Hot areas of the roof are mapped.
2. Choosing the system: The material and thickness are agreed in the quote.
3. Installation: The layer is installed and protected.
4. Measurement and documentation: Thickness is measured at spread-out points.
