Why roof thermal insulation differs in Aldawadmi

Main roads in or near Aldawadmi: King Abdulaziz Road, Dawadmi Bujadiyah Road. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data).

Team note on Aldawadmi: 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..

Aldawadmi sits at about 976 m above sea level, according to SRTM open elevation data, which places it on higher inland ground well above the coastal plains. For a clinic owner, that elevation shapes the roof load more than most people expect. Sites at this height see wider day-to-night temperature swings and stronger direct sun on exposed surfaces, so the roof slab cycles between heat and cooling more sharply than in lower, humid areas. Insulation on a clinic roof therefore has to manage heat gain through the day and heat loss at night, not only one of the two.

Each of these local conditions has a practical effect on the job. Because the roof takes strong sun and a large temperature range, a continuous layer of XPS boards, priced at SAR 12–30 per m², helps keep the treatment rooms and waiting areas at a steadier temperature, which reduces strain on cooling equipment during the hottest hours. Liquid roof waterproofing, at SAR 8–25 per m², is usually applied over the insulation to protect it from rain runoff and from moisture trapped beneath the slab. A bitumen membrane, at SAR 15–35 per m², offers a heavier-duty alternative where the roof has regular foot traffic from maintenance crews or rooftop plant units. Spray foam, at SAR 20–45 per m², can fill irregular shapes around parapets, vents and service penetrations where board joints would leave gaps.

Owners who manage clinics in this area tend to avoid a few predictable errors. They do not assume the cheapest per-square-metre option is the right one, because a thin layer that cracks under thermal movement costs more to repair than to install correctly. They do not seal a roof while cracks in the slab remain open, which is why crack injection at SAR 40–120 per metre is often scheduled first. They also avoid leaving rooftop water tanks uncoated, since tank internal coating at SAR 25–60 per m² protects the water that patients and staff rely on. Finally, they plan access and drainage before materials arrive, so the insulation and waterproofing layers are installed dry and in the right order.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs that call for roof thermal insulation

The following signs are worth checking before they grow:

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

Where the problem usually comes from

• No thermal insulation under the roof protection.
• A common cause: old insulation that has deteriorated.

Tools we use in Aldawadmi

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.
