Is a roof in Baqiq worth waterproofing before you buy, or at handover? Start with the place itself. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data), and that matters for how a roof is judged, because the question is not only the price of the work but the condition of the surface it will sit on. Roof waterproofing is priced by the square metre, and the range you will see depends on the system chosen. Liquid roof waterproofing runs at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m². Those figures let you estimate the cost of a roof before you commit to a contractor.

When you visit, the inspection should follow a clear order. Walk the whole roof surface first and look for cracks, ponding areas, blistering and any sign of old repair. Where a crack is visible, note its length, because crack injection is priced per metre at SAR 40–120 per m, and a long run of cracking changes the budget quickly. Check the parapets, drainage outlets and the junction with the walls, since leaks often start at the edges rather than the middle. Look at the ceiling below for staining, and ask the seller or the inspector to explain any patch they have made. If the building has a water tank on the roof, check its internal condition as well, because tank internal coating is priced at SAR 25–60 per m², and that cost is easy to overlook during a handover.

Before the visit, prepare what the inspector will need. Gather any previous repair records, warranties and invoices, and note the date of the last waterproofing work if you know it. Clear access to the roof and to the ceilings below, and arrange for the roof to be dry, since wet conditions hide defects and make a fair assessment harder. Write down your questions in advance, including which system was used before and whether the drainage has been checked. With those papers and answers ready, you can compare quotes on equal terms and decide whether the roof needs work before the sale closes or should be negotiated into the price.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Signs worth paying attention to

The following signs are worth checking before they grow:

• 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.
• A common cause: wrong falls towards the drains.
• A common cause: cracks in the roof slab.

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.
