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 schools in Taif starts with the height of the site. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), and that elevation shapes what a technician looks at before any material goes down. On a roof that is exposed to strong sun and sudden temperature swings, the first check is the condition of the existing surface: whether it is sound, dry, and free of loose material. Bitumen membrane for roofs is priced at SAR 15–35 per m², and that range reflects how much preparation the surface needs, so the first inspection is about what is already there rather than what the job might look like on paper.

Several points can only be settled at the site visit. The technician has to walk the roof, note the falls and low spots where water would collect, check drainage outlets, and look at the edges and upstands where the membrane meets walls and parapets. Cracks and joints are measured on the spot, since crack injection is priced separately at SAR 40–115 per metre and may be needed before the membrane is laid. Access to the roof, the time school operations allow for work, and the condition of any adjoining areas such as tanks or basements are also judged in person. Where a school has more than one building, each roof is assessed on its own, because the same membrane can perform very differently depending on exposure, age and slope.

Information that helps the technician is worth gathering before the visit. Bring the age of the roof, any past leak history, and records of earlier repairs or coatings. Note whether the roof holds water after rain, whether there is insulation below the surface, and whether any part is used for water storage that might need a separate tank coating at SAR 25–55 per m². Clear guidance on which areas are occupied and when they are quiet makes scheduling practical. With these details in hand, the technician can match the membrane scope to the real condition of the building and give the school a clear picture of the work involved.

For schools, the larger jobs are planned for weekends and holidays.

Signs that call for bitumen membrane

These are the signs most often linked to bitumen membrane:

• A flat concrete roof that needs waterproofing
• Old rolls that are cracking

Where the problem usually comes from

• A common cause: no protection layer.
• Seams that were not welded properly — we check this before anything else.

How we choose the tool in Taif

The steps in order

1. Preparation: Cleaning, priming and repairs.
2. Torch welding: Overlaps are welded and checked.
3. Details: Upstands, drains and bases.
4. Protection and flood test: Protection is laid after a successful flood test.
