Is a bitumen membrane the right choice for a duplex roof in Hafr Albatin, and what does it cost? In this city, bitumen membrane sits in the middle of our price range, at SAR 15–35 per m², which makes it a practical option for flat roofs on duplex homes. Hafr Albatin's centre sits about 312 m above sea level, so the same membrane service applies across the town, and the price range is what you should plan around before a contractor visits.
Before any quote is written, the inspection should cover the whole roof surface so the scope matches what the membrane actually has to protect. The inspector checks the existing surface for cracks, ponding areas, and any old coating that is lifting or peeling. Where the roof meets walls, parapets, and drains, the inspector looks at the joints closely, because these are the places where water most often gets in. The inspector also notes how the roof is laid out and how much area needs covering, so the quote can be measured per square metre rather than estimated from the outside.
To make the visit useful, prepare a few things in advance. Clear the roof of water tanks, loose items, and stored materials so the surface can be inspected in full. Note any past leaks, including where they appeared inside the home and after which rains, since that history tells the inspector where to look first. Have your property papers ready, and be ready to say whether the roof is used for anything, such as a water tank stand or a seating area, because that affects how the membrane is laid. If other waterproofing is being considered for the same home, such as a bathroom or a basement, raise it at the same visit so everything can be quoted together and the work scheduled in one visit.
In a duplex, the two floors often share lines, so tests are done floor by floor.
