What is specific about Buraydah for roof waterproofing

The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data). Team note on Buraydah: 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 for offices and commercial complexes in Buraydah starts with the basics of the site itself. The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data), so a technician begins by noting how the roof falls and where water is likely to collect across a large flat area. Before any product is discussed, the first check is the existing membrane: whether it is lifting, blistered, or split along seams, and whether the drainage outlets and parapet edges are clear. For liquid roof waterproofing, the price range is SAR 10–25 per m², and for bitumen membrane it is SAR 15–35 per m². Those rates are a starting reference only, because the choice depends on what the roof already has underneath.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to measure the true roof area and the length of any cracks that need injecting, since crack injection is priced at SAR 40–115 per metre. The condition of the substrate must be inspected on foot, including any ponding, rust on metal fixings, and places where foot traffic or rooftop units have worn the surface. Access to the roof, the presence of equipment that must be lifted or protected, and the timing of work around occupied floors below are also settled on site. If the roof area adjoins a water tank or a basement wall, those are assessed separately, with tank internal coating at SAR 25–55 per m² and basement waterproofing at SAR 50–145 per m², and the scope is confirmed only after inspection.

To help the technician, the client should have ready any previous waterproofing records, roof drawings showing outlets and levels, and a note of recent leaks with the rooms they affected. Information about the roof's use, such as whether it carries heavy plant or is walked on regularly, shapes the choice between a liquid system and a membrane. Where insulation is planned, XPS boards at SAR 10–30 per m² can be considered as part of the build-up, and spray foam at SAR 20–45 per m² is another option to weigh against the existing structure. Clear answers to these questions let the technician arrive with the right materials and give a realistic scope on the first visit.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

Signs worth paying attention to

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

Where the problem usually comes from

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

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.
