Before any quote is made for a bitumen membrane on a restaurant roof in Sabya, the first thing to note is the town's location. The centre of Sabya sits about 40 m above sea level, according to SRTM open elevation data, and the town is about 16.7 km from the sea coast, based on OpenStreetMap. Those facts shape the early checks: a roof at this elevation and distance from the coast is treated as an inland commercial roof, so the technician looks first at drainage falls, existing ponding, and how water currently leaves the kitchen extract and plant areas.
Some points can only be settled on the day of the site visit. The technician will walk the roof to judge the condition of the existing finish, the state of any laps and upstands, and whether the substrate is sound enough to take a new membrane. The visit is also where the deck is checked for cracks, the number of penetrations such as vents, hoods and pipes is counted, and the access route for materials and crew is confirmed. None of these can be fixed from a distance, so they remain open until someone stands on the roof.
For the technician, a few details help the visit go smoothly. Ask the restaurant to clear the roof of stored items and equipment, and note any rooftop areas used for bins or grease storage. Share the date of the last recoat if it is known, and mention any past leaks in the dining room or kitchen ceiling. Access to the roof should be arranged in advance, and the restaurant should mention if trading hours limit when work can be done. With this information in hand, the technician can confirm the membrane specification and give a clear, itemised estimate after the inspection.
For restaurants, visits are planned outside service hours and recorded for the premises file.
