Our square building sat in a neighborhood that had thrived as long as it has been a neighborhood. The buildings were a mix of old and new. There were considerations for building a new building that had to be met by the local authority. It was easier and cheaper to redo the interior of a building to make it suitable for a tenant than to build something brand new. We gutted the old square building taking out the second floor entirely. The interior had high ceilings. We called a firm that does roof installation in Manhattan NY to have them tell us how much it would be to fully remove the roof and replace it. The roof was flat and was made up of metal trusses with corrugated metal sheeting and a rubber membrane and gravel on top.
The metal trusses were rusted, and so was a lot of the corrugated metal. It looked bad from the inside. No amount of flat black paint was going to hide it. The tenant was a premium lessee, and we were accommodating. Technically the trusses could be saved, but new ones would sure look a lot better. Something had bent a couple of the truss uprights on a couple of them, and someone had cut one to make room for a piece of equipment that was no longer there.
The whole roof was taken off. You could see the sky from inside the building. The new trusses had been made by a steel fabricator, and bright corrugated sheathing was put on top. It brightened up the interior when the roof was back on. It looked really nice. No more leaks either! We are very happy with the result. The construction went fast and without issue. The neighbors like that a lot, and our new premium tenant is very happy.
