Roof waterproofing for apartments in Alula
In short: In Alula (Alula), roof waterproofing for apartments begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Pricing starts from Liquid roof waterproofing (per m²) (SAR 8–25 per m²), and other items are quoted after the visit.
Before we start: what we know about Alula
Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).
Roof leaks in apartment buildings usually start small: a hairline crack near a parapet, a blocked outlet, or a membrane that has lifted at the edges. Water then tracks down into the top-floor ceiling, and by the time stains appear, the damage has often spread. In Alula, the most common complaint we see for apartment roofs is this slow seepage rather than sudden flooding, and it tends to be ignored until plaster begins to flake.
The centre of Alula sits about 697 m above sea level, which shapes how a roof should be treated. Intense sun at that elevation and wide daily temperature swings cause surfaces to expand and contract, so repairs that rely on flexible layers tend to outlast rigid ones. For a flat apartment roof, liquid roof waterproofing at SAR 8–25 per m² is often the starting point because it bonds well to an existing surface and can be applied without stripping the whole roof. Where the substrate is sound but the slab has a few hairline cracks, crack injection at SAR 40–120 per metre can seal the weak lines before the coating goes on. A bitumen membrane at SAR 15–35 per m² is a heavier option when the roof has ponding areas, and XPS boards at SAR 12–30 per m² can be used as insulation under a protective finish, which helps with heat as well as water.
Before booking a visit, ask the company which of these methods they would use for your specific roof and why. Ask whether they will check the parapets, drainage outlets and the junction where the roof meets the wall, since most leaks start there. Request a written breakdown of the area being treated in m² and the length of any cracks in metres, so you can compare quotes on the same basis. Ask how long the roof must stay clear of foot traffic after coating and whether the building's water tanks sit on that roof, because tank coating is priced separately at SAR 25–60 per m². A clear answer to these questions tells you whether the crew understands roofs at this altitude.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
When do you need roof waterproofing?
These are the signs most often linked to roof waterproofing:

- A common cause: damaged waterproofing around tank and AC bases.
- Cracks in the roof slab.
