Roof thermal insulation in Aljumum: the local context

Team note on Aljumum: 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 Aljumum sits about 200 m above sea level (SRTM open elevation data).

The first thing a technician checks in Aljumum is the roof's exposure to altitude and weather. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data), so the roof is the part of the home most open to sun, wind and rain runoff. Before any emergency work, the technician looks at where water is actually entering, whether the insulation layer has lost its contact with the roof deck, and whether the existing membrane has split or lifted at the edges. Liquid roof waterproofing typically runs SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m², and these two figures often shape the first conversation about which route suits the damage found.

The following points are left to the site visit, because they cannot be judged from a description. The technician needs to measure the exact roof area and the length of any cracks, since crack injection is priced per metre at SAR 40–120 per m. They will check whether the insulation is XPS boards, priced at SAR 12–30 per m², or spray foam at SAR 20–45 per m², and whether it is wet or dry beneath the surface. They will also decide whether the water is coming from the roof itself or from a parapet, drain outlet or rooftop tank connection, because a leaking tank is handled differently and tank internal coating runs SAR 25–60 per m². Final pricing and sequencing depend on these measurements, so none of them should be assumed in advance.

To help the technician arrive prepared, the homeowner should note when the leak first appeared, whether it follows rainfall or heavy heat, and which rooms beneath the roof show staining. Photographs of ceiling marks, the roof surface and any visible cracks are useful, as are the approximate roof dimensions and the age of the existing waterproofing if it is known. Please also say whether there is a rooftop water tank and where it sits, and whether the roof is used as living space or only for access. Clear answers to these questions let the technician plan the emergency repair in one visit rather than two.

If water is flowing, close the main valve first, then call or message with photos.

Signs that call for roof thermal insulation

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

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

The most common causes

• 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 Aljumum

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.
