Do you need to waterproof your apartment roof in Khobar, and what will it cost? Khobar's centre sits about 9 m above sea level, and the city is about 1.8 km from the sea coast, so roofs here face damp sea air and seasonal rain. Liquid roof waterproofing typically runs SAR 10–25 per m², bitumen membrane SAR 15–35 per m², spray foam SAR 25–35 per m², and XPS boards SAR 10–30 per m². For a roof with visible cracks, crack injection is priced at SAR 40–120 per m, which is a sensible first step before any full coating. Your choice depends on the roof's condition, its access, and how much of the surface needs work.
A roof waterproofing visit in an apartment building usually follows a set order. The inspector first walks the full roof surface and checks the parapet walls, drainage outlets, and the joints where the roof meets the stairwell or water tanks. Cracks and blisters are marked and measured, because crack injection is quoted per metre, while coated areas are measured per square metre. Where tanks sit on the roof, the inspector looks at their condition too, since tank internal coating is a separate service priced at SAR 25–60 per m². The inspector then records the findings and proposes a scope, so you see exactly which areas are treated and why.
Before the visit, clear the roof of loose items, planters, and stored goods so the inspector can reach every corner and see the surface clearly. Gather any previous repair records or waterproofing warranties for the building, and note where you have seen leaks, damp patches, or ceiling stains in the apartment below. If the building has a shared roof, confirm access with the building committee or caretaker in advance. Having these details ready lets the inspection focus on the real problem areas and helps you compare the proposed options against the price ranges above.
In apartment buildings, the floor below is often where a leak shows first.

This depends on the condition of the old layer. If it is intact and stable, a new layer may be applied. If it is damaged, it must be removed. A technician will determine this after inspection.
What is the best type of roof waterproofing for Khobar's climate?
The choice depends on the surface and its use. Bituminous rolls and liquid polyurethane coatings are common for exposed roofs to resist heat and humidity, while cementitious materials suit tanks and bathrooms. The contractor determines the best type after inspection.
