Roof waterproofing in Alquwayiyah: the local context
The centre of Alquwayiyah sits about 811 m above sea level (SRTM open elevation data).
Roof waterproofing work in Alquwayiyah starts with a basic check of how water moves across the roof, because the town sits about 811 m above sea level and the ground and building layout shape where runoff collects. For hotels and serviced apartments, the first things a technician looks at are the roof slope, the drainage outlets, and any spots where water has already pooled or stained the ceiling below. Liquid roof waterproofing is typically priced between SAR 8 and SAR 25 per m², and bitumen membrane between SAR 15 and SAR 35 per m², so the choice of system is usually made once the roof surface and its condition are clear. Crack injection, priced at SAR 40 to SAR 120 per metre, is often the first repair to scope where hairline cracks appear around parapets or joints.
Several points can only be settled at the site visit. The technician needs to see the actual roof area, how many rooftop plant bases, tanks and access hatches must be worked around, and whether the existing layer is a membrane that can be bonded to or must be removed. The condition of the substrate, the presence of moisture under old coatings, and the state of any upstand flashings are judged on the spot and cannot be fixed from a description. Where a roof also covers water tanks or a plant room, the tank internal coating (SAR 25 to SAR 60 per m²) and any insulation needs are confirmed in person, as is whether XPS boards (SAR 12 to SAR 30 per m²) are needed for thermal protection beneath a new finish.
To help the technician prepare, the owner or property manager should note the building's age, the last time the roof was treated, and any past leak locations, especially those on upper floors of serviced apartments where guests may have reported damp. Photographs of ceiling stains, a rough sketch of the roof with its drains and equipment marked, and access arrangements for guest-occupied floors all save time. Mention whether the work must be carried out in phases so that occupied rooms are not disturbed. With this information, the visit can focus on verifying the scope and agreeing a plan that suits the hotel's operating schedule.
For hotels and serviced apartments, rooms are handled in batches to keep units available.
