Additionally, planning your installation during the off-peak roofing season might save you both time and money.

• Best time is during mild, dry weather.

• Avoid extreme cold or heat.

• Plan for the off-season to potentially save on costs.

How to Install Metal Roofing: Step-by-Step Guide

If you're ready to take on the task of installing metal roofing, this step-by-step guide will walk you through the essential processes. Following these steps will ensure that your roof is installed properly, providing you with a durable, weather-resistant structure for years to come.

Step 1 – Apply the Underlayment

Before installing your metal roofing panels, it’s crucial to first apply an underlayment to protect the roof deck from moisture and extreme temperatures. Begin by unrolling the underlayment across the roof, making sure it’s laid flat without any wrinkles. 

As you unroll, remove the adhesive backing in sections to prevent sticking or creasing. Each strip should overlap the previous one by 6 to 8 inches to create a watertight barrier. Once in place, cut the underlayment flush with the roof edge to avoid excess material sticking out.

• Ensure the underlayment is flat and smooth.

• Overlap each layer to create a solid barrier.

• Remove adhesive backing in sections to maintain control.

Step 2 – Order Panels to Fit

Measuring your roof correctly is essential to ordering the right length of metal panels. Try to order panels that run the full length of your roof to avoid seams, as they can create weak spots where leaks might occur. 

For large roofs, you may need professional assistance to lift and place the panels onto the roof, especially if they're long. Panels are typically delivered on a flatbed truck, and a lift or crane can help move them safely to the roof without damage.

• Measure roof length, width, and slope accurately.

• Order full-length panels when possible to avoid seams.

• Use a lift for panels too large to carry manually.

Step 3 – Bend Trim Ends Closed

Before you install the trim, you'll need to cut and bend the ends to create clean, sealed edges. This process helps prevent water from seeping into vulnerable areas. With aviation snips, make one-inch cuts along the trim at each bend, creating tabs. 

Use a hand seamer to fold these tabs inward, ensuring a snug fit against walls, corners, or any other interruptions in the roofline. Properly bent trim not only improves the roof’s appearance but also strengthens its water resistance.

• Make one-inch cuts to create foldable tabs.

• Bend the trim inward for a clean, water-resistant finish.

• Use a hand seamer for better precision.

Step 4 – Fasten Eave Trim

Eave trim is vital for protecting the edges of your roof from water damage and providing a finished look. Secure the eave trim along the roof’s edge, ensuring it's tightly fastened to the fascia with one-inch roofing nails. 

In colder climates, it's essential to install the eave trim over the underlayment to protect the roof from ice dams, while in warmer areas, it can go underneath. Proper placement helps keep water from penetrating beneath the metal roofing panels.

• Attach the trim securely to the fascia.

• In colder climates, install the trim over the underlayment.

• Use evenly spaced nails to ensure stability.

Step 5 – Set the Metal Roofing Panels

Now, it's time to place the metal roofing panels. Begin at the bottom edge of the roof and work your way up. Lay each panel over a foam closure strip to keep water and pests from getting underneath the metal. Position the panel so it overhangs the eave by about an inch, then line it up with your reference chalk line to ensure everything is straight. Stick the panel in place with butyl tape, ensuring it fits snugly and is consistent with the roof’s alignment.

• Use foam closure strips to block water and pests.

• Align panels with a chalk line for a straight installation.

• Overhang the panel by one inch from the eave.

When to Hire a Roofing Company

While DIY metal roofing can save on labor costs, there are instances when hiring a professional roofing company might be the better option. For those with little experience, working on a roof can be dangerous and time-consuming, especially with the complex measurements and tools involved. Additionally, professional roofing companies are familiar with local building codes and can ensure that the installation meets all regulations.

Some roofing projects, especially for larger or more complex homes, may require special tools, equipment, or expertise. Professionals are also more equipped to handle potential issues like leaks, improper sealing, or structural concerns, ensuring your roof remains protected for years to come.

• DIY roofing can lead to costly mistakes.

• Working at heights poses a safety risk.

• Professionals offer warranties and insurance coverage for their work.

Conclusion

Installing a metal roof can be rewarding for homeowners seeking a durable, long-lasting roofing solution. By following this detailed guide, you can ensure that each step is completed accurately and safely.
