Roofing/Siding Screws

 

 

Roofing screws play a key role in keeping a metal roof secure and watertight. Each screw is

designed with a rubber washer that compresses when fastened, creating a tight seal that helps

prevent water from getting through the roof.

 

Using the correct type and quantity of screws ensures the panels stay firmly in place andperform as intended over time.

 

Proper screw selection and spacing help protect against leaks, wind movement, and long-term

wear!

How to Calculate Screw Quantity

As a general guideline, plan on one bag of screws for every 100 linear feet of panel, which works out to approximately one bag per 300 square feet of panel coverage.

 

This allowance covers standard fastening patterns for panels and trim while providing a small buffer for waste.Screw length is also important.

 

For roof applications, it is recommended to use 2" screws to ensure proper penetration into the wood substrate. For siding applications, 1" screws are typically sufficient.

 

Keep in mind that roof complexity, additional trim, and tighter fastening requirements may increase screw usage.

 

When in doubt, it’s always better to have a few extra screws on hand than to run short during installation.
