Roof thermal insulation in Alqunfudhah: the local context

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data). Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Team note on Alqunfudhah: 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..

An office owner in a commercial complex often treats the roof as a problem only when staff start complaining about heat in the top-floor rooms or when air conditioning bills climb. By then the building has been absorbing sun on a large, flat surface for years. The roof of a multi-storey office or shopping block can carry a large share of the heat load, so insulation decisions made here affect comfort on every floor below and the running cost of the whole building.

The local facts give useful context. The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. Being this close to the coast means the air carries salt and humidity, which can speed up wear on exposed roof materials and their fixings. For an owner, this means a roof system should be chosen for coastal exposure as well as heat, and that surface protection and insulation need to be considered together rather than as separate jobs.

A practical approach starts with a visual and moisture check of the existing roof, looking for cracks, ponding water and damaged joints. Next, the owner should decide the insulation layer, where rigid XPS boards are one option, priced in the range of SAR 12–30 per m², and the waterproofing layer is another, with liquid roof waterproofing in the range of SAR 8–25 per m² and bitumen membrane in the range of SAR 15–35 per m². Cracks found in the check should be sealed before the new layers go on, with crack injection priced at SAR 40–120 per metre. The owner should then request itemised quotes per square metre so that the roof area can be compared directly across offers, and schedule the work outside peak summer heat so the new surface can cure properly.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

When do you need roof thermal insulation?

These are the signs most often linked to roof thermal insulation:

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

Where the problem usually comes from

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

Tools and methods, and when we use them

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.
