Existing Problems

Before installation, make sure to fix any leaks in the roof and replace any weak sheeting or rafters. The underlying structure must be carefully inspected for any indications of excessive weight from the old roof, such as buckled trusses or sagged decking. This makes sure that the metal roof screws have a solid surface to grip upon installation.

Follow Manufacturer Specifications

To be sure you’re installing something according to the right instructions, review the manufacturer’s specifications and warranties. Pay close attention to trim details, safety considerations, and appropriate fastener application.
