What is specific about Aljumum for roof waterproofing
Team note on Aljumum: 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.. The centre of Aljumum sits about 200 m above sea level (SRTM open elevation data).
A clinic owner in Aljumum usually has a flat or low-slope roof that carries air-conditioning units, plumbing vents and sometimes a water tank. Medical staff and patients depend on the building being dry and quiet, so a small leak can quickly turn into a ceiling stain, a damp treatment room or an electrical problem. The owner often has to plan repairs around opening hours, which makes timing and the choice of system just as important as the price.
The centre of Aljumum sits about 200 m above sea level, according to SRTM open elevation data. That height matters for roofs because it places the property in an area where rooftop exposure to sun, wind and temperature swings is significant, and these conditions wear down surface coatings over time. For a clinic, this means a roof system should be chosen for durability as well as first cost, and any old coating should be inspected before a new one is applied. Liquid roof waterproofing is commonly priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 12–30 per m², so owners can compare options within a clear budget range.
A practical approach starts with a site walk to mark cracks, ponding areas, blocked drains and the condition of the parapets. Next, repair any cracks, since crack injection is priced at SAR 40–120 per metre and should be finished before the roof is coated. Then clean the surface and let it dry fully before applying the chosen system. Once the work is complete, schedule a follow-up inspection after the first heavy rain and keep a simple record of the roof area, materials used and the date of each repair, so future maintenance can be planned without disrupting patient care.
For clinics, work is scheduled around patient hours and kept to the areas that need it.
