Roof waterproofing in Turaif: for companies (annual contract)

What is specific about Turaif for roof waterproofing

The centre of Turaif sits about 827 m above sea level (SRTM open elevation data).

Roof leaks are the most common problem we see on company buildings in Turaif, and they usually start with small cracks in the parapet joints and the edges where the membrane meets drainage outlets. By the time staff notice damp ceilings or stained walls in offices and storage rooms, water has often been moving under the surface for months. For a business, the cost is not only the repair but the disruption to operations, stock and equipment, which is why an annual contract that schedules inspection before the problem spreads makes more sense than reacting to each leak.

The local setting shapes the approach. The centre of Turaif sits about 827 m above sea level (SRTM open elevation data), so the site is on a raised plateau rather than low ground. That affects how rainwater moves across a roof and where it collects, so drainage points and falls need checking as part of the work, not just the membrane itself. Liquid roof waterproofing is priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m², so the right system depends on the roof's condition, access and how much insulation the building needs. For buildings with water tanks, tank internal coating at SAR 25–60 per m² is a separate line item that should be scoped at the same time, and for crack repairs, crack injection is priced at SAR 40–120 per metre.

Before the visit, ask the provider to confirm which areas of the building are in scope, including roofs, terraces, basements and any tanks, and to state the rate basis for each. Ask for a written note of the drainage points they will check and how they will record the condition of existing membranes. Find out how often inspections are included in the annual contract, how emergency call-outs are handled, and whether repairs made during a routine visit are covered under the same agreement. Finally, ask who will be on site, how access to occupied floors will be arranged, and how work will be scheduled around your business hours so operations are disturbed as little as possible.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
