What is specific about Tabuk for roof thermal insulation

Team note on Tabuk: 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 Tabuk sits about 762 m above sea level (SRTM open elevation data).

The centre of Tabuk sits about 762 m above sea level, and that height shapes what a technician looks at first on an apartment roof. At this elevation the air is often cooler at night than in coastal Saudi cities, but the sun during the day is strong, so a roof takes heavy heat load in the afternoon and then loses it quickly after dark. For that reason the first checks are the roof surface, any existing waterproofing layer, and the condition of the joints where the roof meets parapets, service ducts and water tanks. A roof that has lost its membrane or has cracked seams will carry heat straight into the top-floor flat below, so these points are inspected before any material is chosen.

Several things cannot be judged from a distance and are left to the site visit. The technician needs to see whether the roof falls cleanly toward drains, whether ponding water is present after a rain, and how deep any cracks run. Access to the apartment below, the age and thickness of the existing slab, and the presence of old bitumen layers that may need removing are also confirmed on site. Where insulation boards are proposed, the technician measures the usable roof area, confirms the layout around air conditioning units and roof hatches, and checks whether the roof is already sloped. Pricing is worked out from these measurements, using the published ranges for each option: XPS boards at SAR 10–30 per m², spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 10–25 per m², and bitumen membrane at SAR 15–35 per m². Crack injection, where needed, is charged at SAR 40–115 per m.

To help the technician, residents should note any past leaks, the location of stains on ceilings below, and whether the building has a water tank on the roof, since tank internal coating is priced separately at SAR 25–55 per m². Information about when the roof was last treated, and whether previous work used bitumen or a liquid system, makes it easier to decide whether to overlay or strip back. Keep the roof clear of stored items and give the technician access to the stairwell and roof hatch on the agreed day. Clear notes on these points let the visit focus on the roof itself, so the recommended work matches what the building actually needs.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

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

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

The most common causes

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

Tools we use in Tabuk

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.
