Roof Insulation in Jeddah: Types, Prices and When You Need It
Jeddah combines high heat, coastal humidity and concentrated seasonal rain — a harsh mix for roofs. The right insulation protects the building and cuts electricity bills at once, but choosing the wrong type wastes money without solving the problem.
When does your roof need insulation?
- Damp patches or peeling paint on top-floor ceilings.
- An unexplained rise in summer electricity bills.
- Noticeable heat when touching the ceiling indoors in the afternoon.
- Cracks in roof tiling or sections lifting.
- Musty or damp smells in upper rooms.
- More than 10 years since the last insulation work.
Types and prices
| Type | Function | Rate per m² | Expected life |
|---|---|---|---|
| Bituminous membrane | Stops leaks | SAR 25 – 45 | 8 – 15 years |
| Liquid membrane | Leaks on complex shapes | SAR 30 – 50 | 6 – 10 years |
| Thermal boards | Reduces heat | SAR 30 – 55 | 15 – 20 years |
| Spray foam | Water + thermal | SAR 35 – 60 | 10 – 15 years |
Which one should you choose?
- Water leaks only: bituminous membrane is the ideal answer.
- Heat and electricity bills: thermal boards.
- Both, quickly: spray foam.
- Complex roof shapes with many corners: foam or liquid membrane, since they are seamless.
- A roof used for walking or sitting: needs a protective layer above the insulation.
Detect leaks before treating
Never insulate before locating the leak precisely — the source may be a pipe inside a wall or a tank rather than the roof.
Modern detection equipment finds the position without random demolition, saving significant repair cost.
Correct execution steps
- Clean the roof thoroughly of dust and damaged layers.
- Treat cracks, joints and the area around drains.
- Create adequate falls to ensure water drains away.
- Apply a primer before the insulation layer.
- Install insulation, turning it up 20 – 30 cm onto surrounding walls.
- Run a 48-hour flood test before the final covering.
