Roof waterproofing in Rafha: the local context

The centre of Rafha sits about 451 m above sea level (SRTM open elevation data).

Rafha sits about 451 m above sea level, and on an emergency roof call the first thing a technician checks is simply where water is entering and whether it is still moving. Begin at the highest point of the roof and trace the path downward: parapet joints, drainage outlets, any penetrations for pipes or aerials, and the junction where the roof meets the wall. Ask the resident to describe when the leak appears, whether it follows rain or occurs in dry weather, and whether the stain is spreading. These answers tell the technician whether the problem is a surface failure, a blocked outlet or a cracked membrane, and they decide how urgently temporary protection is needed.

Several matters are left to the site visit, because they cannot be judged from a phone call. The true condition of the existing layer, whether it is bitumen, liquid coating or an older board system, can only be confirmed by lifting a small section. The extent of the damage, the number of metres of crack and the area needing treatment, will be measured on the roof itself. The technician will also decide whether a liquid roof waterproofing system, a bitumen membrane or a spray foam layer suits the substrate, and will confirm the price band that applies once the area is known. Any sign of water tracking into a bathroom or below ground would be assessed on site, since basement waterproofing and bathroom waterproofing are priced separately.

To help the technician arrive prepared, residents should clear access to the roof and the hatch or stairway, and note the roof's approximate size, the number of drainage outlets and any recent works. Photographs taken during rain, showing the leak and the water's route, are very useful. Please mention if a water tank sits on the roof, since tank internal coating is a separate job and its contents may need to be drained first. Keep the area below the leak clear, move valuable items, and place a container beneath the drip. Describing any earlier repairs, including sealant or patching, lets the technician avoid covering a fault that was already dealt with and focus on the real source of the water.

If water is flowing, close the main valve first, then call or message with photos.

When do you need roof waterproofing?

If you notice one of these signs in Rafha, it is a good moment to talk to the team:

• The old waterproofing is cracking
• Stains on the top-floor ceiling after rain
• Water pooling on the roof

Where the problem usually comes from

• A common cause: cracks in the roof slab.
• Damaged waterproofing around tank and AC bases — we check this before anything else.
• A common cause: wrong falls towards the drains.

Tools and methods, and when we use them

How the work is done, step by step

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
