Roof thermal insulation for duplexes in Makkah
In short: In Makkah (Makkah), roof thermal insulation for duplexes begins with the roof, falls and drains survey and the thermal camera; nothing is opened until the position is clear. The centre of Makkah sits about 301 m above sea level (SRTM open elevation data). Published price: Spray foam (per m²), SAR 25–35 per m²; anything else is quoted after the inspection.
Roof thermal insulation in Makkah: the local context
The centre of Makkah sits about 301 m above sea level (SRTM open elevation data). Team note on Makkah: 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..
Consider a family that owns a duplex in Makkah, with two floors and a flat roof that takes the full afternoon sun. Upstairs, the rooms often feel warm well into the evening, and the family uses air conditioning hard for much of the year. For an owner like this, the roof is usually the first place where heat enters the home, so insulating it is often the most useful improvement they can make.
The centre of Makkah sits about 301 m above sea level, according to SRTM open elevation data. This is useful to know because it shows the city is set in a high, dry valley rather than on the coast, so the main problem for a roof is intense direct sun and heat gain rather than damp sea air. For a duplex owner, this means the insulation choice should focus on blocking heat from above. Roof insulation with XPS boards, priced at SAR 15–30 per m², is a common option because it gives a continuous layer that slows heat moving down into the upper floor. Spray foam, at SAR 25–35 per m², is another route that seals gaps well on uneven concrete slabs.
Start by inspecting the roof surface for cracks and old waterproofing, since insulation works best on a sound base. Next, repair any cracks using crack injection, which costs SAR 40–125 per metre, so the roof is dry before anything is added. Then decide on the insulation layer, comparing XPS boards with spray foam for your roof’s shape and access. Once the insulation is laid, protect it with a liquid roof waterproofing coat, at SAR 10–25 per m², or a bitumen membrane at SAR 15–35 per m², depending on how much foot traffic the roof sees. Finally, ask for the work to be checked for even coverage before the roof is used. Taking these steps in order keeps the cost predictable and the upper floor noticeably cooler.
In a duplex, the two floors often share lines, so tests are done floor by floor.
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
The most common causes
- Old insulation that has deteriorated.
- No thermal insulation under the roof protection — we check this before anything else.
Tools we use in Makkah
| Tool | What it finds | When we use it in Makkah |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
How the work is done, step by step
- Thermal survey: Hot areas of the roof are mapped.
- Choosing the system: The material and thickness are agreed in the quote.
- Installation: The layer is installed and protected.
- Measurement and documentation: Thickness is measured at spread-out points.

Common questions about roof thermal insulation in Makkah
What does finishing work typically include?
It covers plastering, painting, flooring, stone or marble walls, ceilings, gypsum, doors, windows, and final electrical and plumbing installations. You can request full or partial finishing, with the scope clearly defined in the price quote.
Is it possible to renovate the building without evacuating the residents?
In many cases it can be carried out in phases without a full evacuation if the damage is limited. However, for extensive structural renovation, a temporary evacuation may be recommended to ensure safety, and the contractor will explain this in their proposal.
Does waterproofing require removing existing tiles?
It depends on the site condition. Sometimes surface waterproofing can be applied over tiles, while deep leaks require tile removal to treat the layer underneath. A technician will determine the best option after inspection.
What is the first step of roof thermal insulation for duplexes?
We start with thermal survey (hot areas of the roof are mapped), then choosing the system (the material and thickness are agreed in the quote).
