Roof waterproofing in Alqurayyat: the local context

The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). Team note on Alqurayyat: 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 waterproofing emergencies in Alqurayyat are first checked for where water is entering and how far it has spread, because the answer decides how quickly the roof needs covering. Alqurayyat's centre sits about 497 m above sea level, so the technician starts by confirming the roof surface, the parapet edges and any drainage outlets that could be channelling water into the building. Before anything else, the team notes whether the leak is at a single point, along a seam or across a wide area, since a single failed patch needs a different approach from a roof that has lost its membrane in several places. Because pricing for liquid roof waterproofing is commonly quoted at SAR 8–25 per m², the scope of the damaged area is also measured early so the client understands the likely range before work begins.

The site visit settles the points that cannot be judged from a description. The technician examines the condition of the existing membrane, whether it is bitumen, liquid-applied or an older layer that has become brittle, and decides whether it can be repaired or must be stripped back. Substrate moisture, the state of any cracks in the screed and the slope needed to move water to the outlets are all assessed on the roof itself. Materials such as bitumen membrane at SAR 15–35 per m² or XPS boards at SAR 12–30 per m² are chosen only after this inspection, and the final method depends on what the surface can take. Work that reaches into the rooms below, such as ceiling staining or water tracking down walls, is noted but its scope is confirmed on site.

To help the technician arrive prepared, it is useful to tell us when the leak began, whether it worsens after rain or after the afternoon heat, and which rooms show staining. Photographs of the ceiling marks and of the roof access point are valuable, as are details of any previous repairs and the age of the building. Note whether a water tank sits on the roof and whether it has been opened or cleaned recently, since that can change how the surrounding area is treated. Clear access to the roof, and a note of any items that must be moved, will let the visit focus on finding the source rather than preparing the space.

If water is flowing, close the main valve first, then call or message with photos.

Signs that call for 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

The most common causes

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

The steps in order

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
