How Many Screws Will I Need for my Metal Roof?
Are you considering replacing your asphalt roof with metal roofing instead? More and more homeowners, contractors, and commercial businesses are starting to turn to metal for their roofing needs and there’s plenty of reasons why it’s such a popular choice.
Metal roofing is long-lasting, durable, resistant to the elements, and far more energy-efficient than asphalt roofing. However, as with any style of roofing you need fasteners to install it properly and avoid leaks and constant upkeep. People often get stuck trying to determine how many fasteners they need to purchase and what types to get. This article will explain the different types of metal roofing, its benefits, how many fasteners you need, and the correct spacing and installation.
How to Determine the Correct Fastener Spacing & Installation
When you want to determine the exact placement and screw spacing for metal roofing there is several factors to consider. Correctly installing your metal roof begins with using the correct tools, and that means using a screw gun and placing the screws properly.
You should attach the screws for metal roofing at both sides of the ribs on both eaves and anywhere the panels overlap. It is recommended to place the screws on the inside flat of the panel--not on the top of the rib. If you attach it on the top of the rib it can prevent a tight seal from forming and could cause leaks.
Attaching the screw on the rib could also cause it to tilt, stretching the screw hole until it’s bigger than the washer hole which then breaks the seal. Rib placement could also cause the screw to pull out of the roof if the wind is high or the conditions extreme. That’s why it’s better to fasten the screw on the inside flat area where it will easily and securely fasten to the panel. But how many screws do you need exactly?

Advantages of Using Screws Instead of Nails for Your Metal Roofing Project
Using screws instead of nails as a fastener when installing a metal roof offers several benefits. For starters, screws just plain have better holding power than nails. After a few years, nails can actually work themselves loose due to the roof contracting and expanding with the weather. Screws will never work themselves loose because of their thread patterns. They also will not bend when put under intense heat like a nail does.
Not only are screws stronger, but they also stay put better due to their threads and can be easily reversed out and replaced if necessary. When they’re installed using a screw gun, screws are much faster than hammering a nail and actually provide better, more accurate control over placement.
