Roof waterproofing in Abu Arish: for companies (annual contract)

What is specific about Abu Arish for roof waterproofing

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

The first thing checked on a roof in Abu Arish is the elevation, because the centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). That height means the roof is not in a low, water-collecting basin, so the technician looks first at how water leaves the roof surface, the outlets, and the parapet edges. Drainage paths decide where the membrane will be stressed, so they are reviewed before any product is chosen. For companies on an annual contract, this first check sets the scope of the year's visits and shows which roof areas will need repeat attention.

The site visit settles the rest. Once the drainage is understood, the technician walks the roof to judge the surface condition, the age of any existing membrane, the presence of ponding, and any cracks or blistering. The choice between liquid roof waterproofing, bitumen membrane, or insulation boards is made on site, since each suits a different substrate and load. Pricing ranges are only a guide: liquid roof waterproofing runs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², and XPS boards SAR 12–30 per m². Where a crack appears, crack injection is quoted separately at SAR 40–120 per metre. The final method and quantities are confirmed only after the roof has been inspected.

To help the technician, the company should share a roof plan with drainage outlets marked, the date of the last waterproofing work, and a note of any leaks reported inside the building, including the rooms and floors affected. Access arrangements, safe working times, and the location of rooftop equipment such as tanks or air units should also be listed. If the building has a water tank with an internal lining, the tank surface area is useful, since tank internal coating is priced separately at SAR 25–60 per m². Clear records like these let the annual visits build on each other instead of starting from scratch.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

Signs worth paying attention to

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

Where the problem usually comes from

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

Tools and methods, and when we use them

From the first visit to the report

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.
