Is roof waterproofing in Alquwayiyah expensive, and what should an owner expect to pay? The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data), and roof work here is priced per square metre. Liquid roof waterproofing is listed at SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m². XPS boards fall in the range of SAR 12–30 per m². Spray foam is priced at SAR 20–45 per m², and epoxy coating at SAR 35–90 per m². These are the published offers for the roof, so the final figure depends on which system suits the surface and on the total area to be treated.
A visit usually begins with a walk across the roof to note the surface type, the slope, and any ponding water after rain. The inspector looks for cracks and checks the joints around parapets, drains, and roof penetrations, since these are the most common leak points. Where cracks are found, crack injection is priced separately at SAR 40–120 per metre, so the length of each crack is measured and recorded. Any bathroom or tank located directly beneath the roof is noted as well, because water that reaches those areas will show up there first. The inspector then compares the roof's condition with the options listed above and sets out which system fits the building.
Before the visit, it helps to gather a few details that make the quote more accurate. Measure the roof area roughly in square metres, and note the number of roof drains and any rooftop tanks or units. Record where leaks have appeared inside the building and when they occur, whether during heavy rain or after it. Keep any earlier repair records or invoices, since they show what has already been tried. Clear loose debris from the roof and make sure the access route is safe for someone to walk. With these details ready, the site visit can move quickly and the price comparison will be far more reliable.
