Why Choose a Metal Roof?

If you’re not sure why you should install metal roofing panels, here are a few reasons why:

1. Durability

Metal roofs can last 50 years or more, outlasting traditional asphalt shingles by several decades. They withstand severe weather conditions, including heavy snow, hail, and high winds, making them ideal for various climates.

2. Energy Efficiency

Metal roofs reflect solar radiant heat, which can reduce cooling costs by up to 25%. They also provide excellent insulation during the winter months, making your home more energy-efficient year-round.

3. Low Maintenance

Unlike other roofing materials, metal roofs require minimal maintenance. Regular inspections and occasional cleaning are typically all that’s needed to keep a metal roof in excellent condition.

4. Aesthetic Versatility

Available in a variety of styles, colors, and finishes, metal roofs can complement any architectural design, enhancing your home’s curb appeal.

5. Environmental Sustainability

Metal roofs are often made from recycled materials and are fully recyclable at the end of their life, reducing their environmental impact.

Preparing for Metal Roof Installation

Before installing your new metal roof, there are a few things you should do to prepare, including:

Planning and Design

The first step in installing a metal roof is planning. This involves selecting the type of metal, finish, and style that best suits your needs and preferences. Popular choices include:

Standing Seam: Features vertical panels with concealed fasteners for a sleek look.

Corrugated Metal: Known for its distinctive wavy pattern, offering both strength and style.

Metal Shingles: Designed to mimic the look of traditional shingles, slate, or tile.

Measuring and Ordering Materials

Accurate measurements of your roof are essential to ensure you order the correct amount of materials. This includes not only the metal panels or shingles, but also underlayment, flashing, fasteners, and sealants.

Removing the Old Roof

In most cases, the existing roofing material needs to be removed. This allows for a thorough inspection of the roof deck to ensure it is in good condition and ready for the new installation.

Inspecting and Repairing the Roof Deck

The roof deck should be free of rot and mold. Any necessary repairs should be made before proceeding with the installation. A solid, flat surface is crucial for a successful metal roof installation.

Installing the Underlayment

Before you install the metal roofing materials, focus on the underlayment. Here’s how:

Choosing the Right Underlayment

Underlayment provides an additional layer of protection against moisture and leaks. Common types include:

Synthetic Underlayment: Offers superior water resistance and durability compared to traditional felt.

Self-Adhering Membranes: Ideal for areas prone to ice dams and heavy rainfall, providing a watertight seal.

Installing the Underlayment

Underlayment is typically rolled out in horizontal courses, starting at the eaves and working up to the ridge. It should overlap each course by a minimum of 4 inches to ensure complete coverage. Fasteners or adhesive strips secure the underlayment to the roof deck.

Installing the Metal Panels or Shingles in 5 Steps

Take a look below to get a basic understanding of how to install metal roofing:

1. Starting at the Eaves

Begin installation at the eaves, working your way up to the ridge. This ensures that each panel overlaps the one below, directing water runoff away from the roof.

2. Aligning and Securing Panels

Align the first panel with the edge of the roof and secure it with the appropriate fasteners. Fasteners should be driven straight and flush to avoid leaks. Follow the manufacturer’s guidelines for spacing and placement of fasteners.

3. Overlapping Panels

Each subsequent panel should overlap the previous one by at least one ridge. This overlap helps to prevent water infiltration. Use sealant or butyl tape between the overlapping sections for added protection.

4. Installing Flashing

Flashing is installed around roof penetrations, such as chimneys, vents, and skylights, to prevent leaks. Flashing should be installed before the surrounding panels to ensure a watertight seal.

5. Trimming and Cutting Panels

Panels may need to be cut to fit around roof features or to match the roof’s dimensions. Use metal shears or a power saw with a metal cutting blade to make clean cuts. Ensure that cut edges are treated with a rust-inhibiting primer or sealant.

Maintenance and Care

If you want to get the most out of your metal roofing installation, these maintenance tips will help:

  • Regular Inspections: Inspect your metal roof at least twice a year, ideally in the spring and fall. Look for loose fasteners, damaged panels, and any signs of rust or corrosion.
  • Cleaning: Keep the roof free of debris, such as leaves and branches, which can trap moisture and cause damage. Clean the roof with a gentle detergent and water to remove dirt and grime. Avoid using harsh chemicals or abrasive tools that could scratch the surface.
  • Addressing Rust and Corrosion: If you notice any rust or corrosion, address it promptly. Sand the affected area, apply a rust-inhibiting primer, and repaint if necessary.
  • Checking Sealants and Flashing: Regularly check the condition of sealants and flashing. Reapply or replace as needed to maintain a watertight seal.
