Why roof thermal insulation differs in Dhahran

The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data). Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Team note on Dhahran: 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 thermal insulation work in Dhahran starts with the location itself. The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data), and the town is about 5.9 km from the sea coast (OpenStreetMap). Those two facts shape what a technician looks at first: how exposed the roof is to coastal air and wind-driven moisture, and how the water on the roof is likely to drain. For company buildings with large flat roofs, the first checks are the condition of the existing membrane or coating, the slope and outlets, and whether any ponding or salt-related wear is visible at the edges and parapets.

Other points are left to the site visit, because they depend on the building itself and cannot be judged from a desk. The technician will inspect the roof deck, note any cracks, blisters or lifted sections, and confirm the thickness and type of existing insulation. Access routes, roof loading, rooftop equipment such as air-conditioning units and cable trays, and the layout of drains and penetrations all need to be recorded on the spot. The site visit also settles which materials suit the roof, whether that is liquid roof waterproofing, a bitumen membrane, spray foam, or XPS boards, since each has different requirements for surface preparation and foot traffic.

Information that helps the technician makes the visit quicker and the quote more accurate. Useful items include the roof plan or drawings, the year of the last roof work, any leak history with the locations where water has appeared inside the building, and the planned use of the roof space. Note whether the roof is a walking area, a storage area or a plant platform, and whether operations can pause while work is done. Price ranges that may appear in a quote for comparison include liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m². Final figures depend on the surface found during the visit.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

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

The most common causes

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

Tools and methods, and when we use them

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.
