Roof waterproofing in Arar: the local context
The centre of Arar sits about 553 m above sea level (SRTM open elevation data).
Wondering whether your apartment building's roof needs waterproofing before the next rains, and what it might cost? In Arar, which sits about 553 m above sea level, roof work is usually priced per square metre, and the range depends on the system chosen. Liquid roof waterproofing typically falls between SAR 8 and SAR 25 per m², while a bitumen membrane runs SAR 15–35 per m². XPS boards sit at SAR 12–30 per m², and spray foam at SAR 20–45 per m². Knowing these ranges helps you compare quotes on equal terms before anyone sets foot on the roof.
A proper inspection starts with a walk over the whole roof surface to look for ponding, cracks, blistered old coatings and weak points around drains, parapets and roof access hatches. The assessor will note where water has already entered the top floor, since staining on ceilings often shows the route the water has taken. Where cracks are present, crack injection is priced per metre at SAR 40–120 per m, so the length of each crack is measured. The assessor then matches the finding to a system and provides a per-m² estimate based on the measured roof area, rather than a single flat figure for the whole building.
Before the visit, gather the building's documents, including any earlier roof repair invoices, warranty papers and the previous coating type if you know it. Note the dates when leaks appeared, and photograph any stains inside the apartment, as this history helps the assessor judge how long the problem has been developing. Clear access to the roof, the stairwell and any locked hatch, and tell the assessor if tenants use the roof for water tanks or equipment. Having these details ready lets the inspection focus on the actual problem and produces a quote you can check line by line.
In apartment buildings, the floor below is often where a leak shows first.
