If you’re looking for a durable and long-lasting roofing solution for your home, metal roofing over shingles is an excellent option. Not only is it cost-effective, but it’s also energy-efficient and fire-resistant. However, installing metal roofing over shingles requires proper planning and execution to ensure a successful installation. In this article, we’ll guide you through the process of installing metal roofing over shingles, step-by-step.

Preparation

Before you start installing metal roofing over shingles, you need to make sure that your roof is in good condition and able to support the weight of the new roofing material. Here are the steps you should follow during the preparation stage:

Inspection of the old shingles

Inspect the old shingles to identify any damage or areas that need repair. Check for any loose, cracked, or missing shingles. If you notice any issues, fix them before proceeding with the installation. It’s important to have a stable base for the metal roofing panels.

Cleaning of the surface

Clean the surface of the roof to remove any dirt, debris, or moss. A clean surface will ensure that the metal panels adhere well and that the roof’s edges are sealed properly. Use a pressure washer or a garden hose to get rid of any buildup on the roof.

Repair of damaged areas

Repair any damaged areas of the roof, including the underlayment, flashings, and vents. Replace any damaged or missing shingles, and make sure that the roof is level and smooth. Any bumps or uneven surfaces can cause problems during the installation process.

Installation

Once the preparation stage is complete, you can start the installation process. Here are the steps you should follow when installing metal roofing over shingles:

Measuring and cutting the metal panels

Measure the length and width of the roof to determine the number of metal panels you’ll need. Cut the panels to size using a metal cutting tool or a circular saw. Make sure that the panels fit the dimensions of the roof and that they overlap each other by at least two inches.

Attaching the metal panels to the roof deck

Attach the metal panels to the roof deck using screws and washers. Make sure that the panels are secured tightly to prevent them from moving or shifting during high winds or heavy rainfall. Use roofing tape or caulking to seal the edges and seams of the metal panels.

Overlapping the panels

Overlap the metal panels by at least two inches to create a watertight seal. This will prevent any moisture from entering the roof and causing damage. Use a metal roofing clip or a hidden fastener system to secure the panels in place. Make sure that the clips are evenly spaced and that the panels are level.

Finishing

Once you’ve installed the metal roofing panels, you need to finish the roof to ensure that it’s weather-resistant and aesthetically pleasing. Here are the steps you should follow during the finishing stage:

Installing trim and flashing

Install trim and flashing around the edges of the roof to create a finished look and prevent water from entering the roof. Use metal trim that matches the color of the roofing panels to create a cohesive look. Install drip edges along the eaves and gables of the roof to direct water away from the roof.

Sealing the edges and seams

Seal the edges and seams of the metal roofing panels using roofing tape or caulking. This will prevent water from seeping into the roof and causing damage. Make sure that the sealant is applied evenly and that all gaps are filled.

Applying protective coatings

Apply a protective coating to the metal roofing panels to prolong their lifespan and protect them from the elements. Choose a coating that’s designed for metal roofing, and make sure to follow the manufacturer’s instructions for application. The coating will also help to reflect sunlight, making the roof more energy-efficient.

Maintenance

To ensure the longevity of your metal roofing over shingles, regular inspections and maintenance are necessary. Here are some maintenance tips that you should follow:

Regular inspection

Inspect your roof at least twice a year, especially after extreme weather conditions. Check for any signs of damage or corrosion on the metal panels. Inspect the seams and edges to ensure that they’re still sealed properly. Look for any debris or buildup on the roof that could damage the panels.

Cleaning and maintenance tips

Clean your roof periodically to prevent dirt, debris, and moss from accumulating on the surface. Use a soft-bristled brush or a pressure washer to remove any buildup on the panels. Avoid using abrasive materials that could scratch or damage the surface of the metal.
