Gable roofs are the most commonly seen roof throughout the country. Besides a flat roof they are the easiest to install for a builder and in today’s construction may be quickly erected using pre-fabricated truss systems. Gable roofs are often done in combination with dormers or valley type connections. The connections, valleys and dormers are inspected carefully by your inspector for leaks, roof surface damage and other defects. A gable roof usually is vented at the ends and may also have other venting systems such as soffit vents, static roof vents, ridge venting or an attic fan.
