Common Commercial Products to Know

Commercial metal roofing is a different world than residential metal roofing, with its own common products, procedures, and requirements that you need to be aware of before you take on a commercial job.
The resources below detail some of the most common types of panels used in commercial metal roofing – the 1.5” Mechanical Seam, 1.75” Snap-Lock, and the 2.0 Mechanical Seam.

The Bidding Process

One of the key differences between residential and commercial projects is the bidding process. Bidding in the commercial space is very competitive, and knowing ways to make your bid stand out – like including value engineering and all the necessary spec information – enables you to win projects and gain momentum.
The following content draws out the bidding process in easy-to-follow steps. We offer strategies for how to put together a winning bid and develop relationships with general contractors that will help you get more jobs in the future.
Weathertight Warranties
Commercial metal roofing projects will often require weathertight warranties, which ensure that a roof is protected should leaking occur. The weathertight warranty process is an added step that isn’t typically a part of residential projects. Below, you’ll find content that covers everything you need to know about weathertight warranties, from its basic definition to how to apply for one.
Portable Rollformers

Commercial projects can be huge, sprawling jobs, with double or triple the footage of a residential project. To remain efficient and keep the profit margin sustainable, it makes sense for some contractors to invest in a portable rollforming machine, which enables you to form the panels you need onsite. This can cut down on wasted time and give you control over the fabrication arm of your business.
