Before we start: what we know about Alquwayiyah
The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).
Does roof waterproofing in Alquwayiyah have to mean tearing up the whole roof and disrupting your household? Not always. The centre of Alquwayiyah sits about 811 m above sea level, and a number of roof systems can be applied over the existing surface without full removal. Liquid roof waterproofing is priced at SAR 8–25 per m², while bitumen membrane is priced at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Each option has a different footprint on your daily routine, so the choice depends on how much of the roof is affected and how long you can accept work on site.
Before any material is chosen, the inspection starts by walking the full roof surface to find ponding areas, cracked screeds, and failed joints around parapets and drains. Where cracks are present, crack injection is measured per metre and priced at SAR 40–120 per m, which lets the surveyor estimate the repair length before work begins. The surface is then checked for moisture and for loose or blistered old coatings that would stop a new layer bonding properly. The inspector also notes the roof's slope and drainage outlets, because water that stands for long periods will challenge any membrane. The result is a written scope that lists each zone, its treatment, and its cost range, so you can compare options on paper before anything starts.
To make the visit efficient, clear the roof access route and move any rooftop equipment, water tanks, or stored items away from the working areas. Note where leaks have appeared inside the building, including the rooms below and the dates they were first seen, since this helps the inspector trace water paths. If you have earlier waterproofing records or photographs, have them ready, along with the approximate roof area in square metres if you know it. Confirm access times with anyone living on the floor below. Having these details prepared helps the visit stay focused and gives you a clearer, more useful estimate.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
