Before we start: what we know about Alqurayyat
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.. The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data).
The first thing a technician checks on a roof in Alqurayyat is the drainage and the existing surface, because the town sits about 497 m above sea level and the roof is exposed to strong sun and sudden rain. Water that stands on a flat roof finds the smallest opening, so outlets, parapets and the junction between the roof and the walls get the closest look before any product is chosen. The technician also looks for cracks and blisters in the old layer, since these decide whether the surface can be patched or must be stripped back. Knowing this order helps residents understand why a short visit often comes before any price is agreed.
Several points can only be settled on the day, once the roof is open to view. The exact area, the number of metres of cracking, the condition of the old membrane and whether the slope is enough to carry water away all need to be measured in person. The choice between liquid roof waterproofing, a bitumen membrane, spray foam or XPS boards depends on what the roof is made of and how it is used, so the final recommendation waits for that inspection. Likewise, any crack injection work is sized after the cracks have been traced along their full length rather than guessed from a photograph.
To help the technician prepare, residents can note the approximate roof size in square metres, whether the roof is used for water tanks or a terrace, and when leaks were last seen and in which rooms. Photographs of ceiling stains and any cracks in the parapet are useful, as is a record of whether the water appears after rain or after the tank has been filled. If there is a basement or a bathroom above the roof area, mention it, because the same leak can travel down. Clear information at the start lets the visit focus on the roof itself and makes the eventual quote easier to follow.
For a residential building, shared risers, tanks and pumps are checked as one system.
