Roof thermal insulation in Hail: without breaking

Before we start: what we know about Hail

The centre of Hail sits about 1002 m above sea level (SRTM open elevation data). Team note on Hail: 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 in Hail starts with the altitude. The centre of Hail sits about 1002 m above sea level (SRTM open elevation data), which means the technician begins by looking at how the roof is built and how it will hold up under the local climate, rather than assuming a standard lowland setup. The first checks are on the roof surface itself: the condition of existing waterproofing, any cracks or soft spots, and whether the slab already carries a layer that must stay in place. Because the site is higher than many expect, the technician also considers how heat and temperature swings will affect the materials chosen, so the roof is treated as a system rather than a single surface.

Several things are left to the site visit, because they cannot be judged from a description. These include the actual slab thickness, the slope and drainage paths, the location of pipes, tanks and roof fixtures, and the width of any cracks that need injection. The technician measures the roof area and checks whether the surface is sound enough for a coating, a membrane or a board layer. Pricing for each option is set only after these measurements. For reference, liquid roof waterproofing is listed at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m² and XPS boards at SAR 10–30 per m², while crack injection is SAR 40–115 per metre. The final choice depends on what the roof shows on the day.

To help the technician, it is useful to have the roof plan or building drawings ready, a note of any past leaks or repairs, and access to the roof with a clear path for equipment. Tell the team if water tanks sit on the roof, since tank internal coating is priced separately at SAR 25–55 per m² and affects the scope. Mention any rooms below the roof that have had damp, because that may link to bathroom or basement waterproofing, which are quoted at SAR 15–40 per m² and SAR 50–145 per m² respectively. Clear information at the start lets the visit focus on the work that matters.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs worth paying attention to

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

Causes we see in the field

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

Tools we use in Hail

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.
