What is specific about Tarout for roof waterproofing

The centre of Tarout sits about 3 m above sea level (SRTM open elevation data). Tarout is about 0.9 km from the sea coast (OpenStreetMap).

Team note on Tarout: 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.. Main roads in or near Tarout: Uhud Road, Al Khaleej Road, Al Aimmah Bridge.

Roof waterproofing work in Tarout starts with the location itself. The centre of Tarout sits about 3 m above sea level, and the town is about 0.9 km from the sea coast. Because of this low elevation and nearness to the shore, the roof, parapets and drainage outlets are checked first for standing water, salt deposits and signs that water has been finding its way through the slab. A flat roof that drains slowly in this setting can hold water for longer, so the technician looks at the falls and outlets before deciding on any coating.

Several things are left to the site visit, because they cannot be judged from a description or a map. The condition of the existing membrane, whether it is blistered, lifting or torn, needs to be seen directly. The position and width of cracks, the state of the upstands at walls and roof edges, and whether the roof is accessible for foot traffic or equipment all affect the method chosen. Prices are also set after the visit, since the finished cost depends on the area measured and the work needed. The available options include liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m². Crack injection, where it is needed, is priced at SAR 40–120 per metre. The right choice among these depends on what the visit reveals.

To help the technician prepare, it is useful to tell us about the roof before the visit. Note the rough size of the roof and whether it is flat or sloped, when the last waterproofing was done, and where you have seen leaks or damp patches inside the rest house or farm building. Photographs of the roof surface, the edges and any stains on ceilings are helpful. Mention whether there is a water tank on the roof, since tank coating is a separate job priced at SAR 25–60 per m². Clear access arrangements, such as where the keys are kept and when the property can be entered, also save time on the day.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need roof waterproofing?

The following signs are worth checking before they grow:

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

Causes we see in the field

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