You may have heard that roofing requires heavy lifting and a lot of muscle power, and this is true, but it’s not the whole truth. The truth is that if you get hired by a Roofing Philadelphia company that doesn’t know any better, then you will end up installing roofs as hard as possible. They’ll give you crates that are too heavy to carry with one hand, they will send you up onto the slippery slope of a steeply sloped roof without making sure they have pads in place to protect your feet from slipping off the edges and falling down.
