Bitumen membrane work for hotels and serviced apartments in Dammam starts with the location itself. The centre of Dammam sits about 12 m above sea level (SRTM open elevation data), and the city is about 4.3 km from the sea coast (OpenStreetMap). Before any quote is made, the technician checks the roof and podium slabs for ponding and falls, because a building this close to the coast and at this height is still exposed to salt-laden air and heavy sun on flat roofs. The first checks are the drainage outlets, the upstand heights at parapets and lift overruns, and the condition of any existing membrane at the joints with walls and pipes.
Several things can only be judged on the day. The technician walks the full roof to see whether the substrate is sound, whether old layers must be removed, and whether blisters or cracks show that moisture is trapped underneath. The site visit also confirms access for the torch-applied or self-adhesive work, the position of rooftop plant and air-conditioning units that must be lifted and reset, and how the work can be scheduled around guest rooms below so that noise and fumes do not reach occupied floors. Where a hotel or serviced apartment shares a roof with other tenants, the timing of hot work and the storage of materials are agreed on site. Any crack, junction or penetration that needs more than surface treatment is recorded, and a separate price is given for it, since crack injection is quoted per metre (SAR 40–120 per m) and is not part of a standard membrane rate.
To help the technician prepare, it is useful to have the roof plan or drawings, the age of the existing waterproofing if known, and any records of past leaks in guest rooms or corridors below. Note whether the building also has a basement, bathrooms needing separate treatment, or water tanks, because these fall under different rates: basement waterproofing (SAR 50–150 per m²), bathroom waterproofing (SAR 15–40 per m²), and tank internal coating (SAR 25–60 per m²). Bitumen membrane itself is priced at SAR 15–35 per m², and a clear measurement of the roof area, with the number and size of upstands and drains, allows the estimate to match the real scope.
For hotels and serviced apartments, rooms are handled in batches to keep units available.
When do you need bitumen membrane?
The following signs are worth checking before they grow:
- Old rolls that are cracking
- A flat concrete roof that needs waterproofing
The most common causes
- Seams that were not welded properly — we check this before anything else.
- No protection layer — we check this before anything else.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Dammam |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
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.

Questions from Dammam
How long does waterproofing take?
It depends on the area, the material type, and the surface condition. Residential roofs are usually completed within a few days, including preparation and testing.
Are the disinfectants used for sterilization safe for drinking water?
Yes, disinfectants specifically designed for drinking water tanks are used at specified concentrations, and the tank is rinsed thoroughly afterward to remove any residue. We recommend asking about the type of materials before starting.
Is it possible to carry out thermal insulation on an old roof?
Yes, it is possible after inspecting the roof, treating cracks, and removing damaged layers. The contractor determines after the site visit whether the roof needs additional preparation before the insulation is installed.
