Bitumen membrane for schools in Tabuk
In short: In Tabuk (Tabuk), bitumen membrane for schools begins with the roof, falls and drains survey and the flood test; nothing is opened until the position is clear. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Published price: Bitumen membrane (per m²), SAR 15–35 per m²; anything else is quoted after the inspection.
What is specific about Tabuk for bitumen membrane
The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data). Team note on Tabuk: 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 school owner in Tabuk typically manages a large, flat roof that takes the full force of the sun by day and cooler, damp nights in winter. Over the years, the roof membrane can lose its grip, and small leaks may only show up after heavy rain. The owner wants the work done without disrupting classes, at a cost that fits the school's budget.
Tabuk sits at a height of about 762 m above sea level, which means its climate is more continental than the coastal cities of the kingdom, with wider swings between day and night temperatures. For a school roof, this temperature movement stresses the surface and can open small gaps at seams and edges over time. A bitumen membrane is a sensible choice here because it is a proven, flexible layer that can handle this movement. At SAR 15–35 per m², it sits in a middle range compared with other roof options such as liquid roof waterproofing at SAR 10–25 per m² or spray foam at SAR 25–35 per m². Owners should compare these figures against the full roof area rather than the rate alone, since preparation and detailing make up a large share of the job.
The practical path begins with a close inspection of the roof, looking for ponding water, cracked edges, and damage around drains and rooftop units. Next, any cracks should be treated before the membrane goes down, and in some cases crack injection at SAR 40–115 per metre may be needed for the worst sections. Then the owner should ask for a written scope that covers surface preparation, the number of membrane layers, and how the edges and upstands will be sealed. Finally, schedule the work during the school holidays so that noise, fumes and access restrictions do not affect students and staff, and arrange a walk-through once the membrane is complete to confirm that drainage flows freely and that no areas were missed.
For schools, the larger jobs are planned for weekends and holidays.
Signs that call for bitumen membrane
The following signs are worth checking before they grow:
- A flat concrete roof that needs waterproofing
- Old rolls that are cracking
The most common causes
- No protection layer — we check this before anything else.
- Seams that were not welded properly — we check this before anything else.
Tools we use in Tabuk
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
The steps in order
- 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.

Practical notes for residents of Tabuk
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- 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.
