Will the roof of my villa in Al Shafa, Riyadh, really need waterproofing, and how do I know? Al Shafa is a largely commercial district with shops and offices, and its centre sits at 24.7969, 46.6401, about 9.9 km from the centre of Riyadh, with an approximate radius of 3 km. The centre is about 656 m above sea level, and the nearest wadi channel is about 1.1 km away. Those are the local conditions that shape how a roof is exposed to heat, dust and sudden rainfall, so a roof that looks sound from the street can still hide problems that a proper check will reveal.

A roof waterproofing visit usually follows a set sequence. The inspector first walks the full roof surface and looks for cracks, blistering, ponding water and any spots where the existing layer has lifted or split. Parapets, drainage outlets, pipe penetrations and the joints where the roof meets walls are checked next, because these are the most common routes for leaks. Where the roof has an older membrane, the inspector assesses whether it can be left in place or must be removed. The findings are then matched to a suitable system, such as liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², or XPS insulation boards at SAR 15–30 per m², and any cracks needing crack injection at SAR 40–125 per metre are marked for separate pricing.

Before the visit, gather a few things that will speed up the assessment. Note any past leaks, including the rooms affected and the season when they appeared, and keep photos of stains on ceilings or walls. Clear the roof of furniture, satellite equipment and stored items so the surface is fully accessible, and tell the inspector where access to the roof is safest. If you have earlier repair invoices or details of the existing roof layers, have them ready, since they help the inspector judge what is already there. With this information to hand, the visit will focus on your villa's roof rather than on general questions.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
