Pinch Seam Metal Roof Details

Structural standing seam metal roof system.

Pinch seam metal roof details.

Outer fenders and inner tub panels are joined in a pinch weld along the bottom side of the jeep s body the seam runs the length of the jeep directly under the doors. These panels generally come with a painted mill finish or a clear acrylic finish. Recommended slopes are 1 12 and greater. When installing snow rail it can be attached to the seams of a standing seam metal roof or be bolted down into a roof.

A contractor can minimize the appearance of edge creep by using lap flashing hemming exposed edges when possible or using a paint pen on visible cut edges. It may be installed over open purlins with a maximum span of 5 on plywood deck or on rigid foam insulation over steel deck. Here the lower sheet is folded over and lapped at least 4 by the upper sheet. The panel has a 1 3 4 high standing seam that snaps together over concealed clips.

Roof pitch the metal roofing panels shown in this manual require a mini mum slope of 2 per foot to ensure proper drainage. Some snow retention systems use roof clamps to pinch the rib of the roof. Refer to the rain carrying table in this booklet for the maximum allowable panel length per slope that will provide adequate drainage. As with all standing seam roof systems sound attenuation example.

Many details in a standing seam metal roof have folds or hemmed edges that conceal the cut edge of the metal. Wide loose lock transverse seam low pinch this seam reduces the chance of water penetration through wind action and is recommended for slopes 3 to 6 per foot. For longer slopes and lower roof pitches contact fabral for other suitable profiles. Snap together seam reduces.

Roof pitch the metal roofing panels shown in this manual require a min imum slope of 2 ʺ per foot to ensure proper drainage. The connecting point where the two separate metal panels meet forms a vertically pointed rib or a seam that is one inch to inch and a half high. Cleats may be used at transverse seams to facilitate installation and limit movement. Standing seam consists of sheet metal roofing panels joined side by side and attached to the roofing deck with concealed fasteners.

Blanket insulation should be installed between the panels and open framing such as purlins or joists to prevent roof rumble during windy conditions. Low slope structural roofing generally used on roof pitches ranging from 12 to 3 12 consists of interlocking panels commonly called standing seam roofing that run vertically along the roof surface. For longer slopes and lower roof pitches contact fabral for other suitable profiles. Refer to the rain carrying table in this booklet for the maximum allowable panel length per slope that will provide adequate drainage.

Corrosion will happen at some point in the lifetime of the roof.
