What is specific about Tabarjal for roof waterproofing

The centre of Tabarjal sits about 548 m above sea level (SRTM open elevation data). Team note on Tabarjal: 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 leaks are the most common problem for hotels and serviced apartments, and they tend to show up first as stains on top-floor ceilings, bubbling paint, or damp patches near parapets and roof drains. Guests notice quickly, and a leak that is ignored for a season can spread into insulation and structural finishes. Because these buildings stay occupied year-round, most owners want repairs done with as little disruption to rooms as possible, which shapes the choice of system.

Tabarjal sits at about 548 m above sea level, so the local approach starts with that elevation in mind. At this height the site is well above the coast, and the roof is exposed to the full force of weather rather than being sheltered by surrounding buildings. For roof work, liquid roof waterproofing is typically priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m². Each option has a different disruption level and lifespan, so the choice depends on how the roof is used, whether it carries guest access or plant equipment, and how much downtime the property can accept. Where a roof has cracks or movement joints, crack injection at SAR 40–120 per metre may be needed before any surface system is applied.

Before the visit, ask the provider which roof system they recommend for your specific roof and why, and request a written scope that lists the area in m², the materials, and the treatment of drains, parapets and upstands. Ask how they will protect occupied floors and guest areas during the work, and whether they can schedule noisy or fume-producing stages outside peak check-in hours. Request a clear statement of what is included in the quoted rate per m² and what would be charged separately, such as crack repairs. Finally, ask for a site inspection before any price is confirmed, so the roof condition is checked in person rather than estimated from photos.

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

Tools and methods, and when we use them

From the first visit to the report

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.
