The last step involves putting down the roof

The last step involves putting down the roof. Once it’s installed, the roofers will put down new guttering to prevent rainwater from getting into the house. This is done before putting down new tiles and then re-shingling overtop of the new roof. The tiles are put down so that they look great and don’t stick together. It may also be necessary to install flashing on the house in order to hide anything that doesn’t look right.
