Bitumen membrane in Jeddah: emergency
In short: In Jeddah (Jeddah), bitumen membrane (emergency) begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Pricing starts from Bitumen membrane (per m²) (SAR 15–35 per m²), and other items are quoted after the visit.
Bitumen membrane in Jeddah: the local context
The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Jeddah is about 2 km from the sea coast (OpenStreetMap).
Team note on Jeddah: 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..
A homeowner in Jeddah notices water coming through the roof slab after a heavy rain, with a damp stain spreading across a ceiling and drips appearing near a skylight. Many owners in this situation have an older flat roof where the bitumen membrane has lost its surface and begun to crack. Others are expats renting a villa who are unsure whether the repair belongs to them or the landlord. In every case the water keeps moving inside the structure while the family waits, so the first hours matter.
The site sits about 2 km from the sea coast, which means the air carries salt and moisture, and the surface of an old membrane can deteriorate faster than in drier inland areas. The city centre also sits about 15 m above sea level, so rainwater runs off the roofs and collects quickly in low points, drains and parapet corners. A bitumen membrane in Jeddah should be inspected at the first sign of ponding or blistering, because the coastal exposure shortens its useful life. For an emergency, expect a bitumen membrane repair to be priced at roughly SAR 15–35 per m², with the final figure depending on the area treated and the access required on the roof.
Start by moving furniture and electrical items away from the wet area and switching off any circuits that run through the damp ceiling. Place buckets under active drips and, if you can do so safely, clear loose debris and standing water from the roof surface and drain outlets. Photograph the damage and the source of the leak so the findings can be shared with a contractor or landlord. Next, arrange an inspection to locate the breach, since a crack or split seam can sit several metres from where the water appears indoors. Ask the contractor to confirm the treated area in square metres and the scope in writing before work begins. Finally, plan a follow-up check after the next heavy rain to confirm the repair holds and that the drains are flowing freely.
If water is flowing, close the main valve first, then call or message with photos.
When do you need bitumen membrane?
The following signs are worth checking before they grow:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
Causes we see in the field
- A common cause: no protection layer.
- Seams that were not welded properly — we check this before anything else.
How we choose the tool in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
From the first visit to the report
- Preparation: Cleaning, priming and repairs.
- Torch welding: Overlaps are welded and checked.
- Details: Upstands, drains and bases.
- Protection and flood test: Protection is laid after a successful flood test.

Common questions about bitumen membrane in Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
What is the first step of bitumen membrane (emergency)?
We start with preparation (cleaning, priming and repairs), then torch welding (overlaps are welded and checked).
How much does bitumen membrane cost in Jeddah?
From our published price list: Bitumen membrane (per m²) SAR 15–35 per m². Quantities are confirmed at the inspection.
What do I get at the end?
Photos of the welds and the flood-test result, in a technical report that carries a verification code.
What we advise against
- Leaving the membrane exposed without protection
What you get after the work
You receive: photos of the welds and the flood-test result, in a technical report with a verification code.
Practical notes for residents of Jeddah
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
