Do I need a permit to add a 10' w x 6' D shed dormer x30'' H in my top floor ? what companies would provide the construction and reroofing?
You must get a permit & it must be engineered as well. Any alteration to a building structure will always require building and usually development permits. Ask your local development and planning dept. on requirements for this addition. Any General contractor specializing in "additions" can do this job
