The centre of Alkharj sits about 439 m above sea level, which means the city's roofs and drains are shaped by a dry, elevated landscape rather than low coastal ground. For apartment buildings, the first thing we check is the roof surface itself: the waterproofing membrane, the screeds, and the edges where the roof meets parapets and stair housings. Sun and heat are the usual cause of wear on exposed roofs, so cracks, lifted edges, and bare patches are looked at before anything else. Where a membrane has aged or split, the crew notes the affected area so the owner or building committee can see exactly where the problem sits.
Next, the drainage path is traced from the roof outlets down through the downpipes to the point where water leaves the building. Outlets are cleared of grit, dust, leaves, and debris, because a blocked outlet is the most common reason water backs up and seeps into the flat below. Each visit is priced in a fixed range, SAR 150–400 per visit, depending on the size of the building and the work needed on the day. Anything beyond a routine clean and inspection, such as repairing a section of membrane, is quoted separately after the site visit, with restoration priced at SAR 50–150 per m² once the area has been measured on site.
Some matters can only be settled on site, including the true condition of the waterproofing beneath the surface, whether the slope of the roof is directing water correctly, and how much of a repair is needed. Technicians will need to know when the building was last treated, whether any leaks have appeared inside the apartments, and where the access hatch and roof keys are kept. It helps to point out the spots that stay wet after rain, any staining on ceilings below, and whether shared tanks or rooftop units sit near drains. With this information ready, the technician can work efficiently and give the owner a clear picture of what the roof needs.
In apartment buildings, the floor below is often where a leak shows first.

Common questions about roof & drain maintenance in Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
