What is specific about Taif for bitumen membrane

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Bitumen membrane work for hotels and serviced apartments in Taif starts with the altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), which means the cooler nights and sharp day-to-night temperature swings that come with that height can stress roof and terrace surfaces. Before any quote is firmed up, the technician checks the existing membrane for blistering, lifting laps and cracked caps, because thermal movement at this elevation tends to show up first at joints and upstands. The bitumen membrane rate for this kind of work is SAR 15–35 per m², and the scope is set only after the surface condition is clear.

Other items are left to the site visit, since they depend on what is physically on the building. The technician confirms the roof falls and whether ponding water is present, inspects drains, outlets and parapets, and records where the membrane meets walls, plant bases and rooftop tanks. If the work touches a basement or a water tank, those are separate scopes: basement waterproofing runs SAR 50–145 per m², and tank internal coating runs SAR 25–55 per m², so the technician notes any such areas and quotes them separately rather than mixing them into the roof figure. Crack repairs on a substrate are priced per metre at SAR 40–115 per m, and the visit establishes how many linear metres are involved. Where insulation is being considered beneath new work, XPS boards at SAR 10–30 per m² are assessed on site against the existing build-up.

For the technician, useful notes include the building's occupancy pattern, since hotel and serviced apartment roofs are often needed with minimal disruption to guests, and the access route for materials up to the roof. Record the roof area in square metres, the number of linear metres of wall upstand, the number and type of penetrations, and any previous repairs. Photograph each elevation and the roof at the time of the visit. Note whether the bathroom or liquid roof options were discussed by the client, with bathroom waterproofing at SAR 15–40 per m² and liquid roof waterproofing at SAR 10–25 per m², so the final scope reflects the building as it is found.

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

Causes we see in the field

• No protection layer — we check this before anything else.
• Seams that were not welded properly — we check this before anything else.

Tools we use in Taif

From the first visit to the report

1. Preparation: Cleaning, priming and repairs.
2. Torch welding: Overlaps are welded and checked.
