A leaking ceiling when it rains, or a top floor that's burning hot in summer? Here are rough prices per square metre, the difference between insulation types, and what to agree with the company.
Most companies charge per square metre including materials and labour. The price depends on the type of insulation, its thickness and the state of the roof.
| Service | Rough price |
|---|---|
| Waterproofing (bitumen / membrane layer) | SAR 25 – 35 per m² |
| Sprayed foam (polyurethane) | SAR 20 – 55 per m² |
| Full waterproofing and heat insulation | SAR 35 – 75 per m² |
| Foam, 5 cm thick | SAR 70 – 90 per m² |
| Example: 100 m² roof, full insulation | SAR 3,500 – 7,500 |
💡 Ask about a "flood test": they fill the roof with water for a day or two to check for leaks before they finish.
⚠️ A very cheap price per m² sometimes leaves out the flood test, cleaning the gutters and sealing around AC pipes. Ask exactly what's included.

A clear sign the waterproofing has failed or there isn't any. Don't wait: water reaches the steel and the wiring.
The roof soaks up the sun's heat. Heat insulation cools it down and cuts the electricity bill.
Cracks let water into the concrete. They need treating before any new insulation.
Usually water coming in from the roof. Fix the damp from above before you repaint below.
The slope is wrong or the gutters are blocked. Clean the gutters and ask the company to correct the slope.
Heat is often coming in through the roof. Heat insulation takes the load off the ACs and helps them last.
Waterproofing only? Heat? Or both? Ask for the exact material and its thickness.
Measure the roof together, and get the area written in the quote.
Agree a one- or two-day flood test before handover.
How many years, and what does it cover? Get it in writing in the company's name.
Does the price include roof edges, gutters, and openings for pipes and ACs?
Look at photos of past jobs and, if you can, speak to a customer a year or two after their roof was done.

Before the rainy season, clean the roof gutters so water doesn't stand.
Don't let anyone fit a satellite dish or an AC and drill through the insulation without sealing it.
After the first big rain, look at the roof and the ceilings below.
A small crack in the insulation is far cheaper to fix early.

Join freeBitumen is for waterproofing; foam insulates against heat and also keeps water out if it's done properly. Many homes need both waterproofing and heat insulation.
Before the rainy season and before summer. Some materials don't work well in extreme heat, so ask the company about timing.
No. Laqeeni is a directory that connects you with the company directly. You agree and pay between you.
