Testimonials & Reviews

What You Need to Know About Roof Pitch

Selecting the ideal roof pitch for your metal building kit is an important decision that hinges on a few key considerations. If your area is prone to heavy snowfall, opting for a steeper roof pitch can help snow management. However, it’s important to balance this with the cost implications, as a higher pitch can increase the overall price of your building.

A 0.25:12 roof pitch strikes that perfect balance for most customers. This pitch is not only cost-effective but is as efficient in bearing snow weight as a 6:12 pitch. While a higher pitch can aid in shedding snow more quickly, remember that it comes with a higher cost. Our goal is to help you make an informed choice that aligns with both your environmental needs and budget, ensuring your building is both functional and financially feasible.
