Picture a restaurant owner in Ahad Rafida who has just opened for the season. The kitchen is busy, the dining room is full, and then a stain appears on the ceiling above the tables after a heavy storm. The roof is the part of the building nobody sees until water starts coming through, and for a restaurant that can mean lost covers, stained furnishings, and a health inspector asking questions. Many owners in this position want the problem solved quickly, but a clear plan saves more money than a rushed repair.

The local facts shape that plan. The centre of Ahad Rafida sits about 2055 m above sea level, so the roof of a restaurant here faces a different climate and exposure from a coastal building. Liquid roof waterproofing costs SAR 8–25 per m², bitumen membrane costs SAR 15–35 per m², and XPS boards cost SAR 12–30 per m², so the choice of system depends on how the roof is used and how much access you need to it. If the restaurant uses the roof for ventilation units or outdoor seating, a system that can be walked on and repaired easily will suit better than one that is hard to reach. Crack injection, priced at SAR 40–120 per metre, is often the right first step where the leak is traced to a single line of cracking rather than the whole surface.

Start by having the roof inspected and marking every place where water has entered, including areas where ceiling staining appears away from the obvious edges. Next, decide whether the roof needs spot repairs or a full new layer, and compare the per-square-metre quotes for the system that matches your use. Ask for the work to cover the drainage outlets and upstands, since those are common leak points. Then schedule the work outside your busiest trading hours, and check the finished surface with a hose test before the next rain. Finally, keep a simple record of the inspection, the repairs, and the date, so that future maintenance is planned rather than reactive.

For restaurants, visits are planned outside service hours and recorded for the premises file.

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

The most common causes

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

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.
