First, you will need to measure the area to be covered and cut the boards to size. Then, screw the boards into place using screws that are long enough to penetrate through the metal roofing panels and provide support. Once the substrate is in place, you can start installing the metal roofing panels. This simple step on how to start metal roofing will have you set for success. 

Know Each Panel by Size

Knowing the size of the panels you'll use for metal roof installation is essential. The most common sizes are 8 feet by 4 feet and 12 feet by 6 feet.

Repeat this process for all four sides of the roof. Make sure the metal roof trim types you choose can be worked on with your tools.

Effective Way to Fix the Cornice Trim

When adding metal roofing installation details, the first thing you need to do is locate and remove the old cornice trim. Next, you'll need to measure and cut the new cornice trim to fit. Once you have the new cornice trim, install it using screws or nails. Be sure to predrill holes for the screws or nails to avoid splitting the wood. Finally, caulk gaps between the new cornice trim and the rest of the house to block the access of moisture and pests. 

Splice and Overlap Planks to Ensure an Accurate Seal

It's essential to splice and overlap planks when installing a metal roof. This will ensure that the roof is secure and will not leak. Here's a step-by-step steel roof installation guide on how to do it:

Once the panels are in place, you can install the ridge cap without worrying about a replacement alternative. Finally, you can screw in the corrugated roofing. 

Overlap the Panels for Proper Installation

The first step when figuring out how to install metal roof panels is to measure and cut your first panel to size, allowing for an overlap of at least two inches. Use a drill to create pilot holes along the overlap. Secure the panels together using screws designed for metal roofing. Seal the seams with a sealant made specifically for metal roofs. Continue measuring, cutting, and installing panels until the roof is complete. 

Attach the Gable Trim Properly

Begin by attaching the gable trim to the rake edges of the roof. Use screws and washers to secure the metal roof eave trim in place. Attach the corrugated roofing sheet to the roof, starting at the bottom edge and working your way up. Once all the panels are in place, screw them into the purlins using washers for added security. Finally, attach the metal flashing around any openings on the roof (such as skylights or vents). 

Attach Ribbed Cap Securely

Before attaching the ribbed cap, ensure the area is clean and debris-free. If you're installing the roofing over plywood, ensure the plywood is in good condition and free of any nails or screws that could come through. The easiest instructions on how to install a ridge cap on a metal roof will require you to start at one end and work your way down, using nails or screws to secure it. Make sure to overlap each piece as you go so there are no gaps.
