What We Do

Definitive Development is a family owned, local Alaskan roofing and general contracting company. Gene Brooks moved to Alaska in 1970 and hasn't looked back. He has been involved in every phase of construction since the mid 70s. Ryan Brooks, his son, grew up working along side Gene. They started focusing on roofing in the late 90s and have been providing Anchorage homeowners with the highest quality roofing ever since. Definitive Development pride ourselves on addressing the entire roof system: Ventilation, Insulation, structure, and roofing. We are the best professionals to call for re-roofs, ice dams, condensation problems, and hot spots. We install and repair all types of roofing. We stand behind our work with the longest labor warranty in the state because we believe you can count on us and our quality.
