Roof rain leaks in duplexes in Jazan are first checked for their location relative to the coast, because the city sits close to the sea. The centre of Jazan sits about 7 m above sea level, and it is about 1.9 km from the sea coast, so salt-laden air and humidity can speed up wear on roof surfaces, sealants and fixings. For that reason, the first check on a leak call is the roof covering itself: whether the membrane, coating or board has cracked, lifted or pulled away at edges, parapets and drains. Where water shows up on the upper floor, the technician also looks at the points where rain can run down into the structure, since a leak on one level often starts at a roof detail rather than inside the flat.

Several things can only be settled at the site visit. The exact source of the water, the slope of the roof, the condition of old layers beneath the surface and whether moisture has already reached the ceiling or walls all need to be seen in person. The technician will decide whether a liquid roof waterproofing system, a bitumen membrane, spray foam or a combination suits the roof, and whether cracks need injecting before any coating goes on. Costs for these options vary by area, and the final scope depends on what the inspection finds, so no fixed approach can be promised from a phone call.

To help the technician arrive prepared, it is useful to note when the leak appears, whether it follows heavy rain or happens in any weather, and which room or ceiling is affected. Photographs of stains, cracks and the roof surface are helpful, as are details of any previous repairs and the age of the roof if known. Please keep the area below the leak clear, move furniture and valuables away from the wet spot, and avoid walking on the roof in wet or slippery conditions. Clear information like this lets the visit focus on finding the real cause quickly.

In a duplex, the two floors often share lines, so tests are done floor by floor.
