What is specific about Alnuayriyah for roof waterproofing

Team note on Alnuayriyah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Main roads in or near Alnuayriyah: King Abdulaziz Road.

The centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

Roof waterproofing work for hotels and serviced apartments in Alnuayriyah starts with a practical check of the site's setting. The centre of Alnuayriyah sits about 49 m above sea level, which is a useful reference point when a technician plans drainage and considers how water will run off a flat or low-pitched roof. Before any material is chosen, the team looks at the existing surface, the upstands, the outlets and the joints around plant equipment, because these are the places where water most often finds a way in. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while bitumen membrane falls within SAR 15–35 per m², and these ranges help guests and property managers understand the options before the visit.

Several points are left to the site visit, because they depend on what is physically on the roof. The technician needs to see the actual condition of the substrate, whether there are cracks that call for crack injection (priced at SAR 40–120 per metre), and whether insulation such as XPS boards at SAR 12–30 per m² would suit the building. The age of previous coatings, the slope, the number of penetrations and any ponding after rain can only be judged on the roof itself. Where a building also has a basement or wet rooms, the team will check those areas separately, since basement waterproofing sits at SAR 50–150 per m² and bathroom waterproofing at SAR 15–40 per m², and the scope may change once the full picture is clear.

To help the technician prepare, it is worth gathering the building's existing records, any earlier waterproofing invoices, and a note of where leaks have appeared inside the rooms below, including which floor and which ceiling. Access arrangements matter too: hotels and serviced apartments usually need the work scheduled around guest occupancy, so a clear contact and access window saves time. Photographs of the roof and of any staining are useful, as are details of roof drains and water tanks, since tank internal coating is priced at SAR 25–60 per m² and may be part of the same job. With this information in hand, the technician can plan the visit efficiently and explain the options clearly to the property team.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs worth paying attention to

The following signs are worth checking before they grow:

• The old waterproofing is cracking
• Water pooling on the roof
• Stains on the top-floor ceiling after rain

Where the problem usually comes from

• Cracks in the roof slab — we check this before anything else.
• Wrong falls towards the drains.
• Damaged waterproofing around tank and AC bases — we check this before anything else.
