Is it time to call a technician about the bitumen membrane on my roof in Khamis Mushait? The usual signs are water stains on the ceiling below the roof, blisters or lifted edges on the surface, cracks where the membrane meets parapets and drains, and ponding water that stays long after rain. The centre of Khamis Mushait sits about 1998 m above sea level, so the roofs here face strong sun, wide temperature swings between day and night, and occasional heavy rain. Those conditions stress bitumen over time, which is why a leak that looks minor can spread quickly. Bitumen membrane work in the city is priced at SAR 15–35 per m², and a technician can tell you early whether a repair or a fuller replacement makes more sense for your roof.
When the technician arrives, the inspection normally starts with a walk across the entire roof to look for splits, bubbling, exposed laps and areas where the surface has lost its granules or gloss. They will check the upstand flashings around walls, skylights, pipes and roof edges, since these joints are the most common points of failure. Next they look at drains and outlets to confirm that water can leave the roof freely. If water has already entered the building, the technician will trace the stain back up to the likely entry point, because the visible damage on the ceiling is often some distance from the actual breach. They may also mark any soft or wet areas of the insulation below the membrane. At the end of the visit you should receive a clear explanation of what is failing, which sections can be patched, and which need broader work.
Before the visit, clear the roof access so the technician can reach every section safely, and remove loose items such as planters, tiles and stored equipment from the surface. Note the dates and locations of any leaks you have seen inside, and take photographs of stains and of the roof after rain if you can. Let the technician know whether the building has had earlier repairs, and bring any previous contracts or maintenance records. If you have a water tank or rooftop plant, mention it, because these affect the layout of the work. Having this information ready helps the technician give you a more accurate assessment on the first visit.
Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
