Why roof thermal insulation differs in Qatif

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.. 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).

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). Because the town is so close to the coast, the technician looks first at how the roof has handled moisture and salt air over time, not only at heat. Surfaces are checked for fresh staining, lifting edges and signs that water has been sitting in low spots after rain or washing. Any earlier waterproofing is noted so the new layers can be matched to what is already there.

The details that depend on the building are left to the site visit. These include the roof slope, the condition of parapets and drainage outlets, whether the roof is accessible for foot traffic, and whether water tanks or rooftop equipment sit on the slab. The technician also decides which materials suit the roof, since a choice between liquid roof waterproofing, bitumen membrane and XPS boards depends on how the roof is built and used. Crack repair is measured on site. Where cracks run through the slab, crack injection is priced per metre, so the length is recorded only after the cracks have been mapped and marked.

To help the technician prepare, it is useful to have the roof plan or any earlier work records, the date of the last waterproofing, and notes on any leaks seen inside the villa after rain. Tell the team whether a water tank sits on the roof, since tank internal coating is a separate scope and affects access. Clear access to the roof, a safe place to store materials, and confirmation of who to contact on the property all speed up the visit. Photos of problem areas taken after rain are especially helpful, because they show where water actually travels rather than where it is assumed to go.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

Signs that call for roof thermal insulation

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

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

Causes we see in the field

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

How we choose the tool in Qatif

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.
