Roof waterproofing in Turaif: preventive periodic check

Before we start: what we know about Turaif

The centre of Turaif sits about 827 m above sea level (SRTM open elevation data).

Turaif is a town in the northern part of Saudi Arabia, and the centre of Turaif sits about 827 m above sea level (SRTM open elevation data). That elevation matters for roofs here. Higher ground means open, exposed surfaces that take the full force of sun, wind and sudden rain, so a roof is often the first part of a home to show wear. Our preventive periodic check starts by looking at how the roof is built and how it has aged, rather than waiting for a leak to appear inside a room.

Because the surface is so exposed, the most common roof option we discuss is liquid roof waterproofing, priced at SAR 8–25 per m². A liquid membrane forms a continuous seamless layer that can follow the small irregularities of a flat roof, which is why it suits many homes in Turaif. Bitumen membrane, at SAR 15–35 per m², is another route where a heavier, traditional layer is preferred. For roofs that carry insulation, XPS boards at SAR 12–30 per m² can be added, and their effect is to help keep the surface below more stable. Spray foam at SAR 20–45 per m² is sometimes used where a lightweight, adhered layer is needed on an irregular surface. The right choice depends on the roof as found, and the check exists to make that judgement before any work is booked.

Owners in the area often make the same few mistakes, and our periodic check is designed to avoid them. Many wait until water is already reaching a ceiling, when the damage underneath has spread. Others treat a visible crack as cosmetic and leave it, though crack injection at SAR 40–120 per metre is a far smaller job when done early. Some also paint over an old surface without cleaning it, so the new layer does not bond. A regular inspection catches these problems while they are still small, and it gives you a clear record of what was checked and when.

Preventive checks follow a written schedule instead of waiting for a fault.

When do you need roof waterproofing?

These are the signs most often linked to roof waterproofing:

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

The most common causes

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

Tools and methods, and when we use them

The steps in order

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.
