Roof thermal insulation in Alhait: for companies (annual contract)

Why roof thermal insulation differs in Alhait

The centre of Alhait sits about 980 m above sea level (SRTM open elevation data).

Alhait sits at the centre of a high, dry plateau, about 980 m above sea level according to SRTM open elevation data, so a roof here faces a different climate load than one in a coastal city. The first thing a technician checks on a company roof is how the insulation layer sits against that exposure, because altitude is linked to strong daytime sun and sharp temperature swings between day and night. Those swings make the roof surface expand and contract, which is why the first checks focus on joints, edges, and any existing crack or lifted seam where heat and movement can open a gap over time.

Several points are left to the site visit, because they depend on the building itself and cannot be judged from a description. The technician will look at the actual condition of the roof deck, the slope and drainage paths, the type of existing covering, and whether water is already pooling or tracking into the structure below. Where a crack is found, the length and access will decide the method, and the cost range for crack injection is SAR 40–120 per metre, so measuring each run on site is needed before a figure can be set. Likewise, the choice between liquid roof waterproofing at SAR 8–25 per m², a bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m² depends on what the roof already carries and how it is used.

Information that helps the technician is practical and simple to prepare in advance. Please note the roof area in square metres, any known leak points or stains on ceilings below, the age of the existing covering, and whether the roof is used for water tanks, equipment, or foot traffic. If the building has a basement or a tank room, mention it too, since basement waterproofing at SAR 50–150 per m² and tank internal coating at SAR 25–60 per m² are separate jobs that can be scheduled together under one annual contract. Clear notes like these let the visit focus on the roof itself and give the company a fair, written scope.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

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

Where the problem usually comes from

• Old insulation that has deteriorated.
• No thermal insulation under the roof protection.

Tools we use in Alhait

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.
