Why roof thermal insulation differs in Jubail

Team note on Jubail: 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.. Jubail is about 0.9 km from the sea coast (OpenStreetMap).

The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

An owner of a hotel or serviced apartment building in Jubail usually has a roof that carries a lot of daily pressure. Guests expect quiet rooms and cool corridors, while the owner must keep energy costs and maintenance under control across many units. When the top floor runs hot, the effect spreads down through ceilings and into rooms that are already booked, so roof insulation becomes a question of comfort, reputation and running costs at the same time.

Jubail sits about 4 m above sea level, and its centre is only about 0.9 km from the sea coast. For a property owner, this means the building is close to salt-laden air and high humidity, which can affect roof surfaces and any joints or fixings exposed to the weather. A roof system chosen for this location should handle both heat and moisture, not heat alone. Because the ground here is low, water that is not drained away quickly can gather on flat roofs, so the choice of waterproofing layer and the condition of the drainage outlets matter just as much as the insulation board underneath.

A practical approach starts with a survey of the existing roof. Check for cracks, blistering, ponding water and any old bitumen that has lost its grip. Repair cracks before anything else, since crack injection is priced per metre and is usually needed only where movement or leaks are visible. Next, decide the layers that suit the roof: XPS boards for thermal insulation, typically priced in the range of SAR 12–30 per m², and a waterproofing finish such as liquid roof waterproofing at SAR 8–25 per m², or a bitumen membrane at SAR 15–35 per m² where a more traditional sheet is preferred. Spray foam, at SAR 20–45 per m², is another option for irregular surfaces. Finally, ask for a written scope that lists each layer, its area and its unit price, so you can compare offers fairly and plan the work around guest occupancy.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

Tools we use in Jubail

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.
