Roof thermal insulation in Afif: the local context

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

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

Is your villa roof in Afif holding heat in the afternoon and keeping you awake at night? Many owners here ask whether insulation is worth the cost on a roof that sits about 1040 m above sea level. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), so the air is cooler than on the coast, but the sun is still strong and the roof surface takes the full load of the day. Roof insulation works by slowing the flow of heat into the rooms below, which is why it matters even in a higher, cooler town. The main options for the roof differ in material and in price. XPS boards cost SAR 12–30 per m², spray foam costs SAR 20–45 per m², and liquid roof waterproofing costs SAR 8–25 per m². A bitumen membrane costs SAR 15–35 per m², so the choice depends on what your roof already has and what you want the insulation to do.

Before any work is quoted, the roof is inspected in a set order. The inspector first walks the full roof area to look for cracks, ponding spots, and old membrane that has lifted or split. Where cracks are found, crack injection is priced at SAR 40–120 per metre, so the length of each crack is measured and noted. The inspector then checks the parapets, drain outlets and the junctions where the roof meets walls, since these are the most common points of leakage. Finally the roof area is measured in square metres so that each option can be priced per m² against the same figure. The result is a written list of the faults, the measured area, and the options that suit the roof.

Preparing for the visit saves time and keeps the quote accurate. Clear the roof of furniture, water tanks' loose covers, and stored items so the inspector can reach every edge and drain. Gather any previous waterproofing records, invoices or warranty papers, because they show which layers are already in place. Note any roof leaks you have seen, including the rooms and the season when they appeared, and whether water has come through after rain or from the tank side. Have the roof access route open and tell the inspector if the roof is used for a tank, a terrace or a rooftop space, as this changes the layout. With these details ready, the inspection can move straight to the measurements and the options.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

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.
