Roof waterproofing for residential buildings in Taif

Before we start: what we know about Taif

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Roof waterproofing in Taif starts with altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), so the first thing a technician checks is how the roof is exposed to the local climate and how water drains off it. At this height, rain and temperature swings test the surface, so the first checks focus on existing drainage outlets, the slope of the roof, and any ponding that would keep water against the surface for long periods.

The points below are left to the site visit, because they depend on the building itself. A technician will look at the condition of the existing membrane or screed, any cracks and where they run, the state of parapets and upstands, and the junctions around roof penetrations such as pipes and access hatches. The choice between liquid roof waterproofing, bitumen membrane, or insulation boards such as XPS is also made on site, since it depends on the roof's use, whether it is walked on, and how much load it carries. Prices vary with the work involved, so for reference, liquid roof waterproofing typically falls within SAR 10–25 per m², bitumen membrane within SAR 15–35 per m², and XPS boards within SAR 10–30 per m². The final figure is confirmed only after measurement.

To help the technician, have ready the roof area in square metres, the building's age, any previous waterproofing work and its approximate date, and notes on leaks seen inside the property, including the rooms and the season when they appear. Access to the roof, the location of the water tank and any roof-mounted equipment should also be clear. Photographs of cracks, drains and visible damage are useful before the visit. Where a leak has been traced to a crack, note its length in metres, since crack injection is priced per metre at SAR 40–115 per m. This information lets the visit focus on the real problem from the start.

For a residential building, shared risers, tanks and pumps are checked as one system.

Signs that call for roof waterproofing

The following signs are worth checking before they grow:

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

Causes we see in the field

• Cracks in the roof slab.
• 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.
