Before we start: what we know about Qatif

The centre of Qatif sits about 5 m above sea level (SRTM open elevation data). Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Team note on Qatif: 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..

A roof rain leak is the most common emergency we see in Qatif, usually starting at the joints where the roof slab meets a parapet, around drainage outlets, or along hairline cracks that open up over time. Water often appears first as a stain on a ceiling or inside a wall, and it can reach the interior long before the source is obvious from above. Because the leak tends to come and go with the weather, many homeowners wait until the damage is severe. A periodic check before the rainy season is the simplest way to catch these weak points early.

Qatif sits about 5 m above sea level, so drainage from a flat roof has little natural fall to move water away quickly, and standing water can sit on the surface longer than owners expect. The town is also about 2.5 km from the sea coast, so salt-laden air can accelerate wear on sealants and exposed surfaces. For a roof, this means the approach is not only to patch the visible crack but to inspect the drainage path, the upstand edges and the condition of the surface coating. Where the roof is small or the leak is limited to one area, a liquid roof waterproofing system, typically SAR 8–25 per m², or a bitumen membrane, typically SAR 15–35 per m², may be suitable, while crack injection, typically SAR 40–120 per metre, can address a single open line. If the water is reaching a basement or a bathroom below, the scope of repair changes accordingly.

Before the visit, ask the provider to confirm which area of the roof they will inspect and whether they will check the drainage outlets and parapet joints as well as the surface. Ask how they plan to test the repair after completion, and whether the quote lists the material type and the area or length being treated. Request a clear breakdown of each item priced per m² or per metre, so you can compare the work against the ranges above. Finally, ask how the work will be scheduled around the rainy season, since a repair applied just before rain may need time to cure. Clear answers to these questions will help you judge whether the visit will address the cause of the leak rather than only its symptoms.

Preventive checks follow a written schedule instead of waiting for a fault.

1. Protect what is below: Move belongings and contain the water first.
2. Drain the roof: Clear the roof drains so water can leave.
