What do you do when rain starts pouring through the ceiling of a classroom in Riyadh, and the school day cannot simply stop? The centre of Riyadh sits about 637 m above sea level, and while altitude does not cause leaks, the city's sudden downpours can overwhelm an old roof within minutes. For a school, the first priority is to protect the people inside, move students away from the dripping area, and then get a qualified team onto the roof as quickly as possible. Pricing for roof work in this city is usually set per square metre, and liquid roof waterproofing typically falls in the range of SAR 10–25 per m², while bitumen membrane sits at SAR 15–35 per m². Knowing these reference figures helps the school make an informed decision once the immediate danger has passed.

Once the team arrives, the inspection usually follows a clear sequence. They begin by tracing the water path, because the spot where water appears inside is often not directly below the source on the roof. They then check the surface for cracks and failed joints, and where cracks are found, crack injection is priced at SAR 40–125 per metre, which is one reason early detection saves money. The roof surface is assessed for blistering or ponding, and the team decides between a liquid coating, a membrane, or spray foam at SAR 20–45 per m², depending on the condition found. Any water tanks on the roof are also examined, and internal tank coating, at SAR 25–65 per m², is considered if the tank itself is a suspected source. Each step is recorded so the school receives a clear account of what was found.

Before the visit, the school can make the inspection faster and more useful. Gather the building plans or any previous roofing records, note the exact rooms and dates where leaks have appeared, and take photographs of stains, cracks, or damp patches. Clear access to the roof and keep the area beneath the leak clear of furniture and electrical equipment. Identify a staff member who can open the roof hatch and accompany the team, and make sure the building's water tank and drainage points are accessible. Having this information ready allows the team to focus on the real cause, reduces the time classrooms are disrupted, and gives the school a solid basis for planning the repair.

For schools, the larger jobs are planned for weekends and holidays.
