One of the most regularly overlooked features of a flat roof is the relative safety involved in maintaining said roof. With a slanted roof, the chances of injury are significantly higher, on account of it being pretty easy to fall off. As long as a flat roof has a safe access point,t he chances of you falling off the roof are extremely low.
The downside to flat roofs is that they can deteriorate much faster than a more traditional roof. This is because flat roofs, unlike slanted ones, aren’t designed to have water just slide off. If the roof has been made well, it should be perfectly flat and made with highly water-proof materials, so it isn’t a massive problem. If this isn’t the case, or even just when sufficient time has passed, water can easily build up on the surface of the flat roof and begin to cause an exponential growth in damage.
So to maintain a flat roof in light of this situation, having ease of access to the roof is essential. Once up on the roof, you can then begin to diagnose where water may start to build up and try and prevent it from doing so, or you can go up there regularly and make sure that you remove any water build up.
