But it can be extremely difficult to match new materials to old.
How to match a roof addition.
Tying a gable roof into an existing roof is a long expensive project usually undertaken only when there is a major addition or renovation to a house.
Rather than a single slope a gable roof consists of two slopes that meet at a peak running down the middle of the roof.
If the ceiling of the new addition can be lowered an inch or 2 this gives us room to build a truss to match on the roof top.
When matched to the angle and proportions of other rooflines on the house your gable roof will add visual interest and character to the home making the addition look like an asset that belongs with the house.
The best way to tie your addition s roof in with the rest of the house is to take cues from the existing architecture.
Or if the addition is for a garage a lot of times the floor is lower than the house floor anyway and it can be adjusted up or down to make a regular framed wall come out slightly lower than the existing house wall.
Also try to match finish materials such as siding roofing and trim.
