Before we start: what we know about Sharurah

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data). Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Team note on Sharurah: 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..

Is a school roof in Sharurah really worth insulating, given the cost? Property owners here ask this often, and the answer depends on how hot the roof gets and how much cooling the building needs. The centre of Sharurah sits about 724 m above sea level, which means the town is well above the coast, yet the roof still takes a heavy share of the sun's heat during the long summer months. A roof left bare transfers that heat straight into classrooms, so insulation is one of the most direct ways to keep teaching spaces usable and to reduce the load on air conditioning.

The inspection starts with a walk over the roof surface and an examination of the existing layers, looking for cracks, blistering, ponding water and any gaps where heat can enter. The surveyor then checks the edges, parapets and drainage outlets, since these are the points where insulation most often fails. Where cracks are found, crack injection is priced at SAR 40–120 per metre, and the surveyor will measure the total length so the crack repairs can be costed alongside the main works. Each roof section is measured in square metres so that the insulation material can be compared on a clear basis. Spray foam is priced at SAR 20–45 per m², XPS boards at SAR 12–30 per m², and liquid roof waterproofing at SAR 8–25 per m². A bitumen membrane falls between SAR 15–35 per m², so the surveyor will recommend the option that suits the roof's condition and the school's budget.

Before the visit, gather the building drawings, the roof area in square metres if it is already known, and any past records of leaks or repairs. Note which classrooms feel hottest and at what times of day, because this helps the surveyor pinpoint problem areas. Clear access to the roof, including the stairs, roof hatch and any locked doors, saves time on the day. If the school has water tanks on the roof, mention them in advance, since tank internal coating is priced at SAR 25–60 per m² and may be included in the same visit. Having these details ready lets the inspection focus on what matters most and gives the school a clear, comparable set of figures.

For schools, the larger jobs are planned for weekends and holidays.

Signs that call for roof thermal insulation

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.
• A common cause: no thermal insulation under the roof protection.

How we choose the tool in Sharurah

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.
