  • Hemming tool
  • Metal snips or shears
  • Pitch gauge
  • Drill with metal cutting wheel attachment
  • Roofing screws
  • Butyl tape

  • Circular saw with compatible blade

Step-By-Step Metal Roof Installation Process

To install a metal roof on your own, you will need to obtain necessary permits, take measurements of the roof area, purchase the correct materials, remove old roofing and make any necessary repairs, install roof underlayment, and then proceed with installing the metal panels and flashing.

Obtain Necessary Permits

Before you get started, obtaining the necessary permits is essential. You’ll need to check with your local jurisdiction about specific regulations and building codes on how to install a metal roof.

The requirement for such permits ensures that every step aligns with safety standards and measures. Neglecting this phase may lead to legal consequences, including fines for noncompliance as per some jurisdictions’ rules.

Once you have detailed plans ready, submit them along with any required documents to your local building department for review.

Take Measurements of the Roof Area

To ensure a proper fit, having the right measurements is key. Start by measuring along the eave, three feet from the corner, or any multiple of three.

Then, at the marked point, measure four feet or the same multiple. Next, snap chalk lines on the panels to mark screw points. These lines should begin six inches from the top of each panel, and additional lines should be snapped every two inches.

Purchase Correct Materials

Having the correct materials is essential for a successful metal roof installation. This includes items such as metal roofing panels, roofing nails, ice and water shield, gable trim, eave trim, self-tapping screws, sidewall flashing, and ridge cap.

By selecting the right materials from the start, you can prevent any delays or issues during the installation process. Take measurements of your roof area beforehand and make a detailed list of everything you need.

Remove Old Roofing and Make Repairs

Before installing your new metal roof, it is crucial to remove the old roofing materials and make any necessary repairs. This step ensures a clean deck for the installation process.

Taking care of these repairs beforehand will ensure a smooth and successful metal roof installation. So, don’t skip this important step—replace, upgrade, or fix any damaged areas before moving forward with your project.

Install Roof Underlayment

The underlayment acts as a waterproof barrier, protecting your home from water infiltration.

It is typically adhesive-backed and is unrolled across the roof, overlapping the previous layer by six to eight inches, providing an extra layer of protection between the metal roof panels and the roof deck.

Properly attaching the underlayment ensures the integrity and longevity of your metal roof, giving you peace of mind knowing that your home will stay dry and protected for years to come.

Install Metal Panels

To install metal panels on your roof, begin by ordering the panels in the correct dimensions. Once you have the panels, trim the ends and overlap them for a secure installation. Make sure to accurately align the panels using a square reference line.

Then, securely fasten each panel to the roof using screws or clips. Finally, check that all panels are properly installed before moving on to the next step in your metal roof installation process.

Install Flashing

Flashing is typically placed at the base of the roof, against the wall, to create a watertight seal and prevent any leakage.

To ensure a secure fit, roofing cement should be applied where the flashing will sit. Properly installed flashing helps protect your home from water damage and ensures that your metal roof remains sturdy and durable for years to come.

Common Mistakes To Avoid During Metal Roof Installation

  • Hire qualified roofing contractors with metal roofing expertise.
  • Plan for expansion and contraction due to temperature changes. 
  • Repair any damaged roof structures before installing a metal roof.

Benefits of Installing a Metal Roof

A metal roof is a smart choice for your home. Why? Because it offers many benefits, such as:

  • Long-lasting: It can last up to 70 years, much longer than other roofs.
  • Weather-resistant: It can handle rain, snow, wind, and hail without damage.
  • Strong: It can support your home’s structure and resist external forces.
  • Lightweight: It is easy to install and does not need extra support.
  • Eco-friendly: It is made from recycled materials and can be recycled again.
  • Energy-efficient: It reflects heat and sunlight, keeping your home cool and saving you money.

With these benefits in mind, it’s no wonder many homeowners choose a metal roof for their homes.

Closing Remarks

A metal roof is a great investment for your home, as it offers durability, style, and energy efficiency. However, installing a metal roof can be challenging if you don’t have the right guidance and tools. By following this 7-step guide, you’re closer than ever to improving your home’s curb appeal with a sleek metal roofing system.
