Roof thermal insulation in Afif: for companies (annual contract)

Why roof thermal insulation differs in Afif

Team note on Afif: 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.. Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data).

Roof thermal insulation in Afif is rarely a question of heat alone. For company buildings on annual contracts, the most common problem is a roof that has been waterproofed but not properly insulated, so the building absorbs heat through the slab during the day and loses it unevenly at night. Staff notice warm offices, air conditioners run hard, and small leaks or surface cracks appear where the roof expands and contracts. Our approach starts by separating these issues, because insulation and waterproofing solve different parts of the same roof and are priced differently. Typical options include XPS boards at SAR 12–30 per m², spray foam at SAR 20–45 per m², and liquid roof waterproofing at SAR 8–25 per m², with bitumen membrane at SAR 15–35 per m² as another route for flat roofs.

Afif sits at about 1040 m above sea level, and the centre of Afif sits about 1040 m above sea level. That elevation matters. Higher ground in this region can mean cooler nights and larger day-to-night temperature swings than coastal cities, so the roof experiences more movement and condensation risk over a year. For that reason we place greater weight on how the insulation layer sits under the waterproofing, and on sealing any cracks before coating. Where cracks are found, crack injection is priced at SAR 40–120 per metre, and it is usually quoted separately so the contract stays clear. For company buildings with water tanks on the roof, tank internal coating at SAR 25–60 per m² is also reviewed during the same visit.

Before the visit, ask for the roof area in square metres, the current roof finish, and any records of past leaks or repairs. Ask whether the building is occupied during working hours, since some materials need dry, quiet conditions, and whether the annual contract includes inspections after heavy rain or seasonal change. Ask how the work will be scheduled around staff, and how the price will be split between insulation, waterproofing and crack repair. A clear written scope before work begins makes an annual contract easier to manage for both the company and the service team.

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

When do you need roof thermal insulation?

The following signs are worth checking before they grow:

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
