Installing a metal roof over shingles is a great way to upgrade your home’s look and reduce energy costs. However, the process does require you to remove the existing shingles before you begin. This can be a time-consuming and physically demanding task, but it’s necessary to ensure a successful installation.

To start, begin by removing the row of shingles at the eave or edge of your roof. Depending on the type of shingle, you may need to use a crowbar or pry bar to loosen them. Once you’ve removed a few rows, you should be able to remove the rest of the shingles by hand. As you work, be sure to inspect the plywood beneath for any signs of damage, such as rot or water damage. Replace any damaged boards before continuing. Once all of the shingles have been removed, you’re ready to move on to the next step.

2) Inspect the plywood for damage

When installing metal roofing over existing shingles, it is essential to inspect the plywood of your roof for any damage or weak spots. Start by removing a few rows of shingles and examine the plywood underneath. Look for any signs of rot, warping, cracking, or other damage. If you find any of these issues, you may need to replace that piece of plywood before you move forward with the installation.

If the plywood looks in good condition, you can continue with the installation. It’s important to note that you will need to create a flat surface for the metal panels to sit on, so if the plywood is warped or uneven, you may need to add additional support before laying down the panels.

3) Install the drip edge

Installing the drip edge is an important step when installing metal roofing over shingles. The drip edge serves two main purposes; firstly, it helps divert rainwater away from the edges of the roof and secondly, it helps hold the metal panels in place. Start by measuring the length of the eaves and use tin snips to cut a piece of drip edge that is slightly longer than the measurement. Position the drip edge at the eaves, with the lower part facing down and the upper part facing up.

Use roofing nails to attach it to the plywood. Next, attach a second piece of drip edge along the rake edge. Make sure that the upper part of the rake edge is facing up so that the metal roofing panels will be able to slide underneath it. Finally, attach a third piece of drip edge along the gable end. Secure it with roofing nails, making sure that it is tight against the plywood.

4) Nail down the metal panels

Once you’ve inspected the plywood and installed the drip edge, it’s time to start nailing down the metal panels. Start at the bottom edge of the roof, working up from left to right. Make sure to line up the panels so that the top and side edges are even.

Make sure to use galvanized nails when attaching the metal panels to the plywood. Use one nail every 6 inches along each seam. If you are using screws instead of nails, use one screw every 18 inches.

It is important to leave a 1/8 inch gap between each panel to allow for expansion and contraction. When you reach the end of the roof, use a tin snips to cut off any excess material.

Finally, make sure to caulk or seal any gaps around nails and screws to prevent water from getting in. This will advantage keep your roof in good condition for years to come!

5) Seal the seams

Once you have all the metal panels in place, it’s time to seal the seams. Sealing the seams of your new metal roofing is an essential step in the installation process, as it will ensure that your roof is waterproof and able to withstand the elements.

First, you’ll need to use a sealant specifically designed for metal roofing. There are several types of sealants available, so make sure to read the labels to find one that will work for your particular application.

Once you’ve chosen a sealant, apply it along the edges of the panels where they meet. Be sure to cover the entire seam for maximum protection.

Next, use a heavy-duty caulk gun to apply a thick bead of sealant to each seam. Make sure to fill any gaps or cracks that may have developed during the installation process. When finished, press down on the sealant with a putty knife or roller to make sure it adheres firmly to the surface.

Finally, use a metal brush or steel wool to scuff the seams and remove any remaining dust and dirt particles. This will ensure that the sealant will stick properly and last longer. With this step complete, you’re now ready to enjoy your new metal roof!
