Metal Roof Gable Overhang

The gable trim combined with sealant provides a watertight seal for your roof system.

Metal roof gable overhang.

Rake trim can be flat with no overhang or it can overhang the gable end like an eave. However for larger extensions you ll need to hire a professional to get up there and remove large portions of the roof before extending the overhang. Rake trim also known as gable trim is a metal flashing finishing piece placed along the roofline at the sloped sides at the end of a residence s dormer or gable. A rake on the gable end of the roof can be created with the construction of additional roof framing.

Then a 2 4 outlooker is placed over the dropped gable and butted into the side of the adjacent full height truss. Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. In extreme versions they appear to create the prow of a ship and are thus known also as prow overhangs.

Gable end overhangs also known as rake overhangs extend all the way to the peak of the roof. It can be made of metal. A typical metal roof overhang may be 2 to 4 inches or even less. It is cut angled and folded onto the roof line and fasteners usually evenly spaced between 12 and 24 inches apart set it in place.

Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials. If a truss roof is used with this method the gable truss is manufactured 3 shorter than the others. For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves. That means you will have 4 of materials loss.

The 6 inches of rigid insulation added to the top of the existing roof deck needed to be done in a manner that was invisible. Three inches is needed for overlaps and a minimum of 1 for ridge preparation. A brow roof is a narrow roof attached to the wall at the level of the first floor ceiling. Striations and bends on the flashing provide strength and match the lines of your other edge trims.

Then the barge or fly rafter is attached to the end of the cantilevered outlooker. Prior to preparing gable trim you will need to know the pitch of your roof. For example if you had 10 0 of coverage then you would need a 10 4 piece of gable trim. Now comes the really really big point.
