Many states and municipalities require a building permit to install a skylight since it affects the roof structure. If you hire a VELUX installer, they will be able to tell you whether you need a permit. Otherwise, check with your local government on building rules and regulations before moving forward with installation. If approved and you opt for do-it-yourself, installation instructions and videos are available.
Unless you are an expert, VELUX recommends requesting a consultation with an installer in your area. You can find one using our installer search tool.
