Roof waterproofing for warehouses in Al Yasmyn, Riyadh starts with the location itself. The centre of Al Yasmyn sits at 24.8169, 46.6361, about 12.2 km from the centre of Riyadh, and it lies roughly 655 m above sea level. That height matters for a flat warehouse roof because it sets the local climate context in which the roof is exposed to sun and heat, and the nearest wadi channel is about 2.1 km from the centre of the district. Because a wadi can carry sudden runoff after rain, our technicians first look at how water would move off the roof and away from the building, including the outlets, drains and parapet edges, before they consider the membrane itself. Al Yasmyn also has both villas and apartment buildings, so warehouses often sit alongside residential areas, and the drainage and access plan should respect that mix.
Several things are left to the site visit, because they cannot be judged from a distance. The technician will check the condition of the existing roof covering, look for blisters, cracks and ponding, and examine the joints around skylights, roof hatches, plant bases and wall upstands. They will confirm the slope and whether it directs water to the outlets, measure the roof area, and assess whether the structure can take the weight of the chosen system. The choice between a liquid roof waterproofing system, a bitumen membrane and insulation boards such as XPS is made on site, after the roof has been seen. Price guidance for each option is shown as a range, and the final figure depends on what the inspection finds.
To help the technician prepare, it is useful to have the building plan or roof layout, the age of the existing roof and any previous repair records, and a note of any known leaks or areas where water collects after rain. Information on how the warehouse is used, including whether heavy equipment or foot traffic crosses the roof, will also shape the recommendation. Clear access arrangements for the roof, the times when work can be carried out without disturbing operations, and the location of any water tanks or rooftop units all help the visit run smoothly and keep the proposal accurate.
For warehouses, work is phased around operations and stored goods.
Signs worth paying attention to

The most common causes

- A common cause: wrong falls towards the drains.
- Cracks in the roof slab — we check this before anything else.
