Before we start: what we know about Alquwayiyah
The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).
Roof waterproofing in Alquwayiyah starts with the town's setting. The centre of Alquwayiyah sits about 811 m above sea level, so a technician will first look at how the roof sheds rain and how the surface has weathered under strong sun and temperature swings. The first checks are on the roof itself: the condition of the existing membrane, any cracks or blistering, and whether ponding water is sitting on the slab. These are quick to see and tell the technician whether the problem is local or spread across the whole surface.
Several things are left to the site visit, because they cannot be judged from a description. The technician will need to measure the roof area in square metres, since most roof systems are priced per m², and to measure any cracks in metres, because crack injection is charged per metre. A liquid roof waterproofing system is usually priced per m² within a range of SAR 8–25, while a bitumen membrane is SAR 15–35 per m², so the choice of system depends on the slab, the access and the level of exposure. The technician will also check whether water is coming through the roof into a room below, and whether it links with a basement, a bathroom or a water tank that may need separate work. Each of these has its own rate, so the visit is where the scope is confirmed.
Information that helps the technician is simple but useful. Tell them when the leak first appeared, whether it is worse after rain, and which room or area shows the damage. Share any previous repair records, the age of the roof, and whether the roof is used for water storage, foot traffic or equipment. Photographs taken during a storm help a great deal. With this information ready, the technician can arrive prepared, check the roof with clear questions in mind, and give a clear proposal that matches the actual condition of your building.
Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
