Why roof thermal insulation differs in Abu Arish

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). 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), and that height matters for how a school roof is first looked at. Before any insulation product is discussed, the technician starts with the roof itself: whether the surface is sound, whether the parapets and drainage outlets are clear, and whether there are any signs of water already entering the building. Because the town is not at sea level, the roof is not sheltered in the way low coastal areas sometimes are, so exposure to sun and wind across a flat school roof is the first thing to note. Only once the base is clear does it make sense to talk about thermal layers, since insulation laid over a damp or cracked surface will not perform as intended.

Several points are left to the site visit, because they cannot be judged from a description. The actual roof area, the slope of the surface, the number and type of penetrations such as vents, pipes and access hatches, and the condition of any existing membrane all have to be measured and inspected on the spot. The technician should also confirm whether the roof is accessible for work during school hours, and whether any adjoining areas such as a basement or water tank need to be included in the same job. Crack length, where cracks are present, is recorded in metres during the visit. None of these figures should be assumed in advance, as they change the scope and the materials needed.

For the technician, a few working notes help the first visit go smoothly. Record the roof in square metres and any crack runs in metres, so the estimate can be built from measured quantities. Note whether the existing surface is bare concrete, an old bitumen layer or a previous liquid coating, since each affects preparation. Ask the school for a window of time when noise and foot traffic can be kept away from classrooms. Photograph the drainage points and parapet edges before work starts, and keep a short written record of the condition found, so the handover to the school is clear and the next maintenance check has a reference point.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to

If you notice one of these signs in Abu Arish, it is a good moment to talk to the team:

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

The most common causes

• Old insulation that has deteriorated — we check this before anything else.
• No thermal insulation under the roof protection — we check this before anything else.

How we choose the tool in Abu Arish

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.
