Roof waterproofing for warehouses in Baqiq starts with the height of the site and the roof itself. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data), so the first check is how the roof drains and where standing water could collect. A flat warehouse roof with a poor fall will hold rainwater against every joint, and that is the first thing a technician looks at before quoting any system. Liquid roof waterproofing is typically priced at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m², so the cost of a system depends on what the roof needs rather than on the area alone.

Several points can only be judged on the site visit. The technician needs to walk the roof and see the condition of the existing surface, the number and size of cracks, and any blistering or lifting at the edges. Crack repair is measured separately, at SAR 40–120 per metre, so the length and depth of each crack must be recorded on the day. The state of the parapets, roof penetrations, drains and the junction with rooftop equipment also cannot be assessed from a description. Where a warehouse has old coatings, the technician will decide whether they can be overcoated or must be removed. Access arrangements, the loading of goods below and the need to keep operations running are likewise settled on the visit.

To help the technician prepare, the client should note the approximate roof area, the age of the existing covering, any history of leaks and the locations where water has been seen inside. A simple sketch showing drains, skylights, and any plant or pipework on the roof saves time. It also helps to say whether the building has a basement or water tanks on the roof, since those are priced separately. For comparison, XPS boards cost SAR 12–30 per m² and spray foam SAR 20–45 per m², so knowing the intended finish early allows the site visit to focus on the right option for the warehouse.

For warehouses, work is phased around operations and stored goods.

When do you need roof waterproofing?

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

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

Where the problem usually comes from

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

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.
