When you're building an addition, you have a multitude of decisions to make. With so much work to be done, it can be easy to overlook one of the most important components of your new addition: its roof. Tying the roof of a new addition in to your existing roof can be extremely frustrating. Not only are there strategic concerns, there are material concerns as well. Not all roofing materials work well together. What's more, adding an addition could void your existing roof's warranty. Make sure you have a competent contractor who will look out for your interests. Also, consider one of these four options for tying in your roof.
Extend Your Gabled Roof
If your addition is going to be placed on a side of your home where the roof peaks, you can do a simple extension. An extension basically extends the length of your gabled roof, a roof with two sloped sides and a single peak, without changing the design overmuch. Extensions can be built at the same height as the existing roof or a bit lower for visual and architectural effect.
Create A Shed Roof
A shed roof is perhaps one of the easiest solutions for extending your roof over your new addition. A shed roof attaches to your home at the high point and extends over the addition at a slight angle, which allows water to shed off of the roof. While easy, a shed roof is the least attractive since it usually looks out of place with the architecture and roof lines of the existing home.
Add Another Gable
If the design of your home permits, you can add another gabled portion to your roof. This option makes the addition look original to the home, but it's more expensive and not always possible. If a gable addition creates a negative peak in your roof line, you will have issues with water intrusion.
Build A Dormer or Two
If you're adding space to a half story, attic, or second story, consider building dormers to raise your roof line and create more space. Dormers are ideal for upper floor expansions because they are simple to install and architecturally appealing.
As you can see, there are several types of roofs that your roofing contractor can use for your new addition. The options that's right for you will depend primarily on the current construction of your home as well as your addition goals.
