When you have a two-story or one-and-a-half story home, and you want to add an addition to the home, you will need to hire a roofing contractor too. There are some very special considerations to be made when you placing your addition, since there are a couple of ways of dealing with the roof. Here are some examples of how the roofing can be done.
Extending the Roof in the Same Directions
When you build up and out on your home, a roof has to go over the addition. The easiest way to achieve this is to just extend the roof in the same directions and along the same parallel lines it currently heads. There is no perpendicular lines and no alteration in shape. The roof on your addition looks like it was part and parcel of the old roof all the time because there is nothing there to define that it was not there before.
Creating Perpendicular Lines in the New Section of Roof
Another option is to create perpendicular lines in the new section of roof. Instead of the new section of roof following the same exact lines as the old roof on the rest of the house, your roofing contractor constructs an entirely new roof shape and makes it meld with the old roof. In essence, he/she creates a brand-new gable, or wing, of the roof, which becomes very obvious by its disconnect from the rest of the roof. This may be done to create interest or to avoid structural damage to the old roof when the new roof may be too large and too heavy for the old roof to support. Even with reinforced extensions from the old roof, the new roof section may need to stand on its own as it covers the addition to your home.
Creating a Combination of the Above
Another option is to create a combination of the parallel and perpendicular lines of the roof. Maybe the roof on the new addition follows the lines of the old roof, but then ends in several gables or dormer windows. Maybe it goes against the angles of the old roof but visually recreates the lines of the old roof. You can discuss these options at length with your roofing contractor while the construction contractor and his/her crew are busy adding your new addition to whichever side of the house you intended to enlarge.
