Before we start: what we know about Qatif

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data). Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Team note on Qatif: 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..

Roof insulation work in Qatif starts with the location itself. The centre of Qatif sits about 5 m above sea level (SRTM open elevation data), and the town is about 2.5 km from the sea coast (OpenStreetMap). Both facts matter for a roof, because the nearness of the coast means salt-laden air is a regular feature of the environment, and a low-lying site can see water collect where drainage is poor. Before anything else, the technician looks at how the roof sheds water, whether any outlets are blocked, and whether the surface shows signs of salt crust or moisture staining that would affect how the insulation is bonded.

Several things are left for the site visit, because they cannot be judged from a distance. The condition of the existing roof slab, the presence of cracks, the slope and the state of parapets and edges all need to be seen in person. The same applies to the access route, the size of the roof, and whether rooftop equipment, water tanks or solar panels will need to be lifted or worked around. Costs for roof work are usually quoted per square metre, so the measured area and the condition of the surface drive the final figure, and a visit is the only reliable way to confirm both. Where a crack is found, it is priced separately per metre through crack injection, so the length of any crack is also recorded during the visit.

Information that helps the technician is practical and simple to provide. Tell the team when the roof last showed a leak, which rooms sit directly below it, and whether the ceiling has ever shown damp. Mention any previous coating or membrane, since an old bitumen layer or liquid finish changes the preparation needed. Share the purpose of the room below, for example a bedroom or a store, because that affects how much attention the insulation layer gets. Finally, note any water tanks on the roof and how they are fixed, as tank surfaces are treated on their own terms. The clearer these details are, the more accurately the visit can confirm the scope before work begins.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

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

The most common causes

• A common cause: old insulation that has deteriorated.
• No thermal insulation under the roof protection.

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.
