Why roof thermal insulation differs in Aldiriyah

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.. The centre of Aldiriyah sits about 655 m above sea level (SRTM open elevation data).

The first thing to check on a roof in Aldiriyah is the altitude. The centre of Aldiriyah sits about 655 m above sea level, which places it on a plateau well above the coastal plain, so roofs here receive strong sun and wide temperature swings between day and night. That exposure matters for insulation because the roof is usually the surface that takes the most heat. Before any product is chosen, check the roof for existing damage, ponding areas, and the condition of any old membrane, since trapped moisture under a new layer will limit how well the insulation performs.

Several decisions are better left to the site visit, because they depend on what the technician finds on the roof itself. These include whether the slab has cracks that need crack injection at SAR 40–120 per metre, how much of the roof needs a liquid roof waterproofing layer priced at SAR 8–25 per m², and whether a bitumen membrane at SAR 15–35 per m² is more suitable for the given slab. The technician should also decide whether XPS boards at SAR 12–30 per m² or spray foam at SAR 20–45 per m² suits the roof structure, and whether any nearby areas such as a basement at SAR 50–150 per m² or a bathroom at SAR 15–40 per m² are linked to the same leak path. Costs listed here are indicative ranges only and the final figure depends on the measured area and the condition found.

To help the technician, prepare basic information before the visit. Note the roof area in square metres, the age of the building, any previous waterproofing work, and where leaks or damp patches have appeared inside. Mention whether the roof is used for water storage, since a tank internal coating priced at SAR 25–60 per m² may be needed in that case, and whether a separate area such as the basement has been affected. Share photos of cracks, staining and drainage points, and say whether the property is being bought or handed over, because that changes what the buyer or seller should expect to be documented. Clear information at the start makes the visit faster and the quote easier to compare.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

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.

Tools we use in Aldiriyah

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.
