What is specific about Abha for bitumen membrane
The centre of Abha sits about 2230 m above sea level (SRTM open elevation data). Team note on Abha: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..
A school owner in Abha usually manages a large flat roof that must stay dry through heavy seasonal rain while the building is in constant daily use. Classrooms, corridors and the staff areas below depend on that roof, and any leak can interrupt lessons and create costly damage to ceilings and equipment. Because the work often has to fit around term dates, the owner needs a clear plan before the first drop of water appears.
Abha sits at about 2230 m above sea level, which shapes how a roof behaves. The high altitude means the sun and temperature swings can stress a roof surface, so the waterproof layer must be able to handle expansion and contraction over time. For a school, bitumen membrane is a common option for flat roofs, priced at SAR 15–35 per m². The per-square-metre rate makes it easier to compare the cost of covering the full roof against smaller repairs, such as liquid roof waterproofing at SAR 10–25 per m², and to decide which approach suits the building's age and condition.
Start by walking the roof after a rain event and marking every puddle, crack and damaged drain outlet. Measure the roof area in square metres so you can estimate the membrane cost across the full surface. Next, arrange a site survey with a qualified contractor who can check the existing substrate, drainage slope and upstands before any material is ordered. Plan the works for school holidays so that noise, access and safety risks stay away from pupils. Finally, ask for a written schedule, a clear description of the materials to be used, and a plan for inspection after completion, then book a follow-up check at the start of the next wet season.
For schools, the larger jobs are planned for weekends and holidays.

Questions from Abha
What happens after the leak location is found?
The service provider gives you a report showing the leak's location and cause, along with a recommended repair method. You can request the repair from the same provider or ask for other offers through the platform.
How can I tell if the leak is inside the wall and not caused by humidity in Abha?
Humidity usually shows up spread out and fades with ventilation, while a leak concentrates in one spot and gets worse over time. Testing with moisture meters and thermal imaging can settle the difference.
Can a bathroom leak cause structural damage?
Yes. Ongoing leaks allow water to reach concrete and steel, causing rust that weakens the structure. Persistent moisture also promotes harmful mold growth. We recommend inspection at the first sign of a leak.
