What is specific about Qatif for roof thermal insulation

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).

Qatif sits close to the Gulf coast, and the centre of town is only about 5 m above sea level, which means rooftop water tends to pool rather than drain quickly once a storm passes. Because of this, the first thing we check on any roof in the area is whether the existing surface still slopes toward its outlets and whether ponding marks are visible after rain. The sea is about 2.5 km away, so salt-laden air is a consideration too, and we look closely at fixings, parapets and any exposed metal before deciding how the insulation and membrane should be laid.

Several parts of the job can only be judged on site. A technician needs to see the actual condition of the screed, the depth of cracks, whether old bitumen has blistered or lifted, and how the roof edges and drainage points are finished. Access routes, the height of parapets and the state of any rooftop equipment also shape the method and the amount of preparation required. Pricing for liquid roof waterproofing, for example, sits in a published range of SAR 8–25 per m², but where the final figure falls within that range depends on what the inspection reveals, so no fixed quote is given here.

For the technician, it helps to know the surface type, the approximate roof area, and whether the roof is accessible for foot traffic or used for water tanks or equipment. Reference points that may be useful include XPS boards, published at SAR 12–30 per m², and bitumen membrane, published at SAR 15–35 per m², both of which may suit different roof conditions. Any previous repair records, leak locations and photographs taken after heavy rain are also valuable, as they show where water actually travels. Gathering this information before the visit lets the site team focus on what matters most and avoids unnecessary delays.

Prices shown on this page come from our own published price list for the city; the final price is set after inspection.

Signs that call for roof thermal insulation

These are the signs most often linked to roof thermal insulation:

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

The most common causes

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

Tools we use in Qatif

From the first visit to the report

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.
