Roof thermal insulation in Aldarb: preventive periodic check

Before we start: what we know about Aldarb

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Does a roof in Aldarb need checking if it seems fine from below? Many owners assume that a dry ceiling means the roof insulation is working, but the roof takes the full sun and the wind before any leak shows indoors. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast, so the roof faces its own mix of heat and exposure. A preventive periodic check looks for early wear before it turns into a water or heat problem inside the building.

The inspection follows a set order. The technician first walks the roof surface and notes the condition of the liquid roof waterproofing and any bitumen membrane, looking for blistering, lifting edges, or bare patches. Next, the crack lines are checked, and any hairline cracks are marked, since a crack injection job is priced per metre and is easier to plan when the length is known. The edges, parapets and drainage points are inspected for pooling or blocked outlets. Where insulation boards such as XPS are present, the technician checks that they are intact and seated correctly. The result is a written list of what is sound, what needs watching, and what needs attention, so the owner can decide on the work in order of urgency.

To prepare for the visit, clear access to the roof hatch or stairs and move any stored items away from the roof edges. Gather any earlier records, such as previous waterproofing or insulation work, the date it was done, and any spots where you have seen damp on the ceiling. Note the parts of the building that feel unusually hot in the afternoon, because these often point to thinning insulation. Keep the roof free of loose debris before the visit so the surface can be read clearly. If the building has a water tank on the roof, make sure the tank lid is accessible, as tank internal coating is considered during the same check.

Preventive checks follow a written schedule instead of waiting for a fault.

Signs worth paying attention to

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

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

Where the problem usually comes from

• A common cause: no thermal insulation under the roof protection.
• Old insulation that has deteriorated.

How we choose the tool in Aldarb

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.
