Before we start: what we know about Alnuayriyah

Main roads in or near Alnuayriyah: King Abdulaziz Road. The centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

Team note on Alnuayriyah: 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..

Alnuayriyah sits about 49 m above sea level, which is a useful starting point for any roof assessment on a rest house or farm in this area. Because the town is relatively flat and elevated, we first check the roof surface, its slope, and how rainwater drains off it, since standing water is one of the first things a technician looks for before deciding on an insulation approach. We also look at the existing finish: whether there is an old bitumen membrane, a liquid coating, or bare concrete, and whether any layers are lifting or blistering. Insulation boards such as XPS, which typically fall in the SAR 12–30 per m² range, only perform well when the surface beneath them is sound, so checking the base comes before any choice of material is made.

Several things are left to the site visit, because they cannot be judged from a description alone. The technician will check the extent and width of any cracks, since crack injection is priced per metre at SAR 40–120 per m and the true length only becomes clear on the roof itself. They will look at the condition of parapets, roof edges, and penetrations for pipes and water tanks, and decide whether a tank internal coating at SAR 25–60 per m² is relevant. Whether spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 8–25 per m², or a bitumen membrane at SAR 15–35 per m² suits the roof depends on the surface, access, and how the building is used. Final figures are confirmed only after this inspection.

To help the technician prepare, it is worth noting the roof's approximate area in square metres, the age of the building, any past leaks or repairs, and whether the roof is used for storage, gatherings, or water collection. Photographs of visible cracks, staining on ceilings below, and the location of water tanks and access hatches are also useful. If the property has a basement or bathrooms that share a roof section, mention this too, because basement waterproofing (SAR 50–150 per m²) and bathroom waterproofing (SAR 15–40 per m²) are quoted separately. Clear information at this stage lets the visit focus on the questions that matter most for your rest house or farm.

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

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

• The AC runs for long hours in summer
• Strong heat on the top floor
• The ceiling stays hot at night

Causes we see in the field

• No thermal insulation under the roof protection — we check this before anything else.
• A common cause: old insulation that has deteriorated.

How we choose the tool in Alnuayriyah

The steps in order

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.
