Before we start: what we know about Abu Arish

Team note on Abu Arish: 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 Abu Arish sits about 67 m above sea level (SRTM open elevation data).

Roof thermal insulation for rest houses and farms in Abu Arish usually starts with heat that builds up under an uninsulated roof and stays in the rooms long after sunset. Rest houses and farm buildings often have large flat or lightly pitched roofs that take the full force of the afternoon sun, so the upper floor or the sleeping areas can feel much hotter than the rest of the property. Many owners first notice this as cracks in the roof surface and damp patches that appear after rain, which is why the insulation and the waterproofing are often planned together.

Abu Arish sits at about 67 m above sea level, which is a useful reminder that it is not a coastal site with humid sea air, but it is still a warm inland location where daytime heat is intense. The approach therefore focuses on reducing the heat that reaches the room below. A common option is XPS boards, priced at SAR 12–30 per m², which give a continuous layer of insulation and can be paired with a separate protective finish. Spray foam, at SAR 20–45 per m², is another option where the roof shape makes boards harder to fit. For the waterproof layer above, liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are the usual choices, and the right one depends on how the roof is used and how much walking or storage it carries. Where cracks already exist, crack injection at SAR 40–120 per metre should be dealt with before any new layer is applied.

Before the visit, it helps to have a few details ready. Note the roof area in square metres, whether the roof is flat or sloped, what material it is built from, and whether it is used for water storage, animals, or equipment. Tell the team where leaks or hot spots have appeared and when. Ask which parts of the property are used most in summer, and whether any tanks sit on the roof, since tank internal coating at SAR 25–60 per m² may also be relevant. Clear answers to these questions let the visit focus on the roof itself rather than on guesswork.

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

When do you need 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

Where the problem usually comes from

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

Tools we use in Abu Arish

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.
