Roof thermal insulation in Rafha: when to call a technician

Why roof thermal insulation differs in Rafha

The centre of Rafha sits about 451 m above sea level (SRTM open elevation data).

Rafha sits about 451 m above sea level, and that elevation is the first thing a technician considers when looking at a roof's insulation. At this height the air is generally drier and the nights can be noticeably cooler than in coastal towns, so heat moves through a roof differently from one season to the next. Before any material is chosen, the technician checks whether the existing insulation has lost its thickness, whether any boards have shifted or cracked, and whether the roof has been sealed in a way that traps moisture underneath. Because the roof is the largest exposed surface in most homes, these checks come first, since a weak section there affects the whole room below it.

Several things can only be judged on the site itself and are left to the visit. The technician will measure the roof area, test how the current layer has aged, and decide between options such as XPS boards at SAR 12–30 per m², spray foam at SAR 20–45 per m², or a liquid roof waterproofing system at SAR 8–25 per m². They will also look at drainage, parapets, and any cracks that need injection at SAR 40–120 per metre, and judge whether a bitumen membrane at SAR 15–35 per m² is more suitable than a liquid finish. Prices in the ranges above are only a guide, because the final figure depends on access, the condition of the surface, and the materials that the inspection shows are needed.

To help the technician, prepare the basic information before the visit. Note when the leak or heat problem first appeared, whether it worsens after rain or in the hot afternoons, and which rooms beneath the roof feel warmest or show damp patches. Clear the roof of stored items if you can, and make sure access through the building is open. If the roof is also shared with a water tank, mention it, because tank internal coating at SAR 25–60 per m² is a separate job and should be assessed at the same time.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.

Signs worth paying attention to

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.
• A common cause: old insulation that has deteriorated.

How we choose the tool in Rafha

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.
