Before we start: what we know about Khobar

The centre of Khobar sits about 9 m above sea level (SRTM open elevation data). Khobar is about 1.8 km from the sea coast (OpenStreetMap).

Team note on Khobar: 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..

For rest houses and farms in Khobar, the most common roof leak is water getting in through the joints around skylights, parapet walls, and where the roof meets the wall, rather than through the open roof surface itself. A leak that appears after a storm often starts at a small crack or a lifted seam that lets water track sideways under the finish. Because these buildings are often used seasonally, a leak can sit unnoticed for weeks, soaking ceilings and insulation before anyone sees a stain. The first step is usually to trace where the water actually enters, then decide whether a targeted crack repair or a full roof treatment is the right response.

Khobar's location shapes that approach. The centre of the city sits about 9 m above sea level, and it is about 1.8 km from the sea coast, so roofs here are exposed to salty, humid air that breaks down sealants and coatings faster than inland properties. Repairs therefore need materials chosen for that exposure, and a patch that looks sound on the day can fail after a few seasons if the surface was not prepared properly. For a farm or rest house with a large flat roof, liquid roof waterproofing typically runs SAR 10–25 per m², bitumen membrane SAR 15–35 per m², and XPS boards SAR 10–30 per m². Where a crack runs along the roof, crack injection is priced at SAR 40–120 per metre, which is often the most economical fix when the damage is localised. Any water tanks on the property can also be affected, and tank internal coating is priced at SAR 25–60 per m².

Before the visit, ask the provider to confirm which part of the roof is leaking and whether they will inspect the joints, parapets and skylights as well as the main surface. Ask how the area will be measured and whether the quote is per square metre or per metre of crack, so you can compare figures on the same basis. Check whether the quote includes surface preparation, and ask what material they propose and how it performs in coastal humidity. Find out how long the work will take and whether the property will need to be unused during it, since rest houses and farms often have guests or stock to plan around. Finally, ask for a written quote that separates the repair from any extra work, 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

The following signs are worth checking before they grow:

• Drips from the ceiling during rain
• Water standing on the roof that does not drain
• A stain growing on the top-floor ceiling

The most common causes

• A common cause: a split in the waterproofing around a tank or AC base.
• A blocked roof drain.
• Damaged waterproofing at the edges.

Tools and methods, and when we use them

How the work is done, step by step

1. Protect what is below: Move belongings and contain the water first.
2. Drain the roof: Clear the roof drains so water can leave.
3. Inspection after the rain stops: The entry point is found on a dry roof.
4. Treatment: A local repair or a waterproofing plan, as the inspection shows.
