Why roof waterproofing differs in Riyadh

The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data). Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah.

Team note on Riyadh: 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..

Roof waterproofing work for hotels and serviced apartments in Riyadh starts with a few basic checks that shape everything else. The city centre sits about 637 m above sea level, so the roof is exposed to strong sun, high daytime heat and sudden rain when storms do arrive. Technicians therefore look first at the condition of the existing surface, noting any blistering, cracking or ponding water, and at how the roof has handled heat over the years. Liquid roof waterproofing is usually priced from SAR 10–25 per m², and bitumen membrane from SAR 15–35 per m², so the first check helps decide which system suits the roof and budget. Where the roof meets walls, parapets and drainage outlets, these joints are inspected closely, because they are the usual points where water finds its way in.

Some matters can only be settled at the site visit. The technician will measure the true roof area, confirm the number of drain outlets and their condition, and look for hidden moisture under the surface. Access arrangements matter too, since hotel and serviced apartment roofs often hold rooftop plant, tanks or guest facilities that must be planned around. Where cracks are visible, crack injection is quoted per metre at SAR 40–125 per m, and the length can only be confirmed on the roof itself. If the roof sits above guest rooms, the site visit also settles how much work can be done during quiet hours and how much protection is needed for occupied floors below.

Some information helps the technician prepare before arriving. It is useful to share the building's age, any previous waterproofing records, recent leak reports from the rooms below, and the typical occupancy pattern so work can be scheduled with minimal disruption to guests. Notes on whether a water tank sits on the roof are helpful, since tank internal coating is priced separately at SAR 25–65 per m². Photographs of ceilings and walls showing damp patches, and the dates they appeared, allow the technician to trace likely water paths. Clear details on these points make the visit faster and the proposed solution more accurate for the building in question.

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

When do you need roof waterproofing?

These are the signs most often linked to roof waterproofing:

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

Where the problem usually comes from

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

Tools we use in Riyadh

How the work is done, step by step

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
