What is a Flat Seam Roof Panel?

A Flat Seam Roof Panel is formed by turning up the intersecting edges, folding them over, and flattening the joint by soldering. Flat seam roofing systems are typically used on roofs that are flat or otherwise have a low pitch. They are also used on curved surfaces such as domes and barrel vaults.

When installing a flat seam roof it is important that the sheathing underneath is continous and covered with a minimum 30LB felt and building paper. This is necessary because the sun heats up the flat seam panels and the building paper hols up the integrity of the felt. Without applying the paper the felt could potentially heat up and stick to the back of the panels. This causes vulnerability to tearing once the panels cool and expand or contract.
