Roof thermal insulation in Najran: the local context

Main roads in or near Najran: Al Jarba Street. The centre of Najran sits about 1309 m above sea level (SRTM open elevation data).

Team note on Najran: 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..

Roof thermal insulation for clinics in Najran starts with the altitude. The centre of Najran sits about 1309 m above sea level (SRTM open elevation data), which means the air is cooler at night than in the coastal cities, while daytime sun on a flat clinic roof can still be intense. Our technicians therefore check first how the roof is exposed, how much sun it takes in each day, and whether the existing layers are holding heat in the rooms below. Because clinics run long hours and keep sensitive equipment and waiting areas comfortable, the check also looks at which rooms sit directly under the roof and how the current surface is holding up.

Several points are left to the site visit, because they cannot be judged from a description. The technician will inspect the roof deck for cracks, ponding and old coatings, and will confirm whether the slab can take a new layer without extra work. They will look at parapets, drainage outlets, rooftop plant and any penetrations for air conditioning, and note where insulation boards or a liquid system would meet walls and upstands. The choice between XPS boards, spray foam, liquid roof waterproofing or a bitumen membrane depends on what the roof already has, so the final recommendation is made on the day. Indicative rates for these options are set out in our price list, but the quote is issued only after the visit confirms the area and condition.

To help the technician, please have ready the roof plan with dimensions, the age of the building and any previous waterproofing records, and a note of which clinic rooms sit below the roof. Tell us about any leaks, damp patches or hot spots reported by staff, and whether the roof is used for equipment or access. Please also mention any work already scheduled on the building so that the roof job can be sequenced around clinic hours. With this information, the visit can focus on the roof itself, and the proposal will match the clinic's real layout rather than a generic estimate.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

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

Where the problem usually comes from

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

Tools we use in Najran

From the first visit to the report

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.
