Does the roof pitch meet the manufacturers minimum roof slope?
Many architectural roof systems are hydrokinetic, which means these systems are designed to perform only in a water shedding capacity. Consequently, the minimum recommended roof slope is usually 3:12. However, there are also some hydrostatic systems that are designed to perform under standing water. The minimum roof slope for these systems can be as low as 1/4:12. 4. Will the roof handle the expected amount of thermal movement? On extremely long runs, the roof may expand and contract more than the panel clip is designed to handle. In this instance, a step up in the eave height will be required. This step up in eave height can also be a very attractive design element. In some cases, the panel may be attached to the substructure at mid span, allowing it to float toward both the eave and ridge, thereby doubling the total amount of allowable roof movement. 5. How well can the panel handle hips, valleys, dormers, roof to fascia transitions, etc., that are typically incorporated into archite
