Roof waterproofing for rest houses & farms in Baish

Before we start: what we know about Baish

The centre of Baish sits about 84 m above sea level (SRTM open elevation data). Team note on Baish: 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 we see on rest houses and farms in Baish. Water tends to find its way in through small cracks and worn joints in the roof surface, and because these buildings are often used only at weekends or during seasonal visits, damp can go unnoticed until stains appear on ceilings or walls. Left alone, that moisture slowly damages plaster, paint and the fittings below, so it is worth checking the roof before the rainy months rather than after.

Baish sits about 84 m above sea level, which is a useful detail when planning the work. The town is not on a high plateau, so rainwater from surrounding ground and from the roof itself can pool or run towards low points on a farm, and some sites collect water near walls and foundations. For a rest house roof, this means the drainage route matters as much as the membrane itself. A liquid roof waterproofing system at SAR 8–25 per m² is often suitable for flat roofs with simple shapes, while a bitumen membrane at SAR 15–35 per m² may suit roofs that see heavier use. For cracks that are already visible, crack injection is priced at SAR 40–120 per metre, and it is usually a good first step before any coating is applied. Where a roof sits over living space and needs extra insulation, XPS boards at SAR 12–30 per m² can be added as part of the system.

Before the visit, ask the provider which system they recommend for your roof type and why, and whether they will inspect the drainage as well as the surface. Ask how they will handle existing cracks and where the water will be directed during and after the work. Request a clear breakdown of the per-square-metre rate, the measured area and any extra items such as crack injection, and ask how they will measure the roof on the day. It also helps to ask whether they will walk the roof with you, point out the problem areas and explain what they found, so you know exactly what you are paying for.

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

Signs worth paying attention to

If you notice one of these signs in Baish, it is a good moment to talk to the team:

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

Where the problem usually comes from

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

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.
