How to Install Metal Roofing Over Shingles?

How to Install Metal Roofing Over Shingles?

Metal roofing has become increasingly popular in recent years due to its durability, energy efficiency, and aesthetic appeal. If you already have shingles on your roof, you may be wondering if it’s possible to install metal roofing over them. The good news is that in many cases, it is possible to install metal roofing over shingles. This can save you time and money by eliminating the need to remove the existing shingles. However, there are some important considerations and steps to follow to ensure a successful installation.

Step 1: Assess the Condition of the Shingles

Before installing metal roofing over shingles, it’s crucial to assess the condition of the existing shingles. If the shingles are in poor condition, such as being curled, cracked, or missing, they should be replaced before installing the metal roofing. It’s important to have a solid, even surface to ensure proper installation and prevent any issues down the line. Additionally, if the shingles are more than one layer thick, it’s generally recommended to remove them before installing the metal roofing.

Step 1.1: Replacing Damaged Shingles

If you do need to replace any damaged shingles, start by removing the old shingle using a pry bar. Carefully lift the shingle and remove any nails or adhesive holding it in place. Once the old shingle is removed, position the new shingle in its place and secure it with nails or adhesive according to the manufacturer’s instructions. Make sure the new shingle is aligned properly with the surrounding shingles to maintain a uniform appearance.

Step 1.2: Removing Multiple Layers of Shingles

If you have multiple layers of shingles and decide to remove them before installing the metal roofing, it’s important to exercise caution. Start by removing the top layer of shingles using a pry bar. Take care to avoid damaging the underlying layers or the roof deck. Once the top layer is removed, repeat the process for any additional layers. It may be necessary to use a roofing shovel or other specialized tools to remove stubborn shingles or adhesive.

Step 2: Prepare the Roof Surface

After assessing and addressing the condition of the shingles, the next step is to prepare the roof surface for the metal roofing. This involves cleaning the roof of any debris, dirt, or moss that could interfere with the installation process. Use a broom or leaf blower to remove loose debris and then scrub the roof surface with a mixture of water and mild detergent. Rinse the roof thoroughly to remove any remaining soap residue. Allow the roof to dry completely before proceeding with the installation.

Step 2.1: Inspecting the Roof Deck

While preparing the roof surface, it’s also a good idea to inspect the roof deck for any signs of damage or deterioration. Look for areas of rot, sagging, or water damage, as these issues should be addressed before installing the metal roofing. If any repairs are necessary, consult a professional roofer to ensure they are done correctly and the roof deck is structurally sound.

Step 2.2: Applying Underlayment

To provide an extra layer of protection against water infiltration, it’s recommended to install an underlayment before placing the metal roofing. This can help prevent leaks and prolong the lifespan of the roof. There are different types of underlayment available, such as synthetic or asphalt-saturated felt. Follow the manufacturer’s instructions for proper installation, ensuring that the underlayment is properly aligned and secured to the roof deck.

Step 3: Install the Metal Roofing

Now that the roof surface is prepared, it’s time to install the metal roofing. Start by measuring and marking the roof to determine the placement of the first metal sheet. It’s important to ensure that the metal sheets are installed with the correct overlap and alignment to create a watertight seal. Use a chalk line or other marking tool to guide the installation process. Begin at one corner of the roof and work your way across, securing each metal sheet with screws or nails according to the manufacturer’s instructions.

Step 3.1: Overlapping the Metal Sheets

As you install each metal sheet, make sure to overlap them properly to prevent water from seeping through the gaps. The amount of overlap required will depend on the specific type of metal roofing you are using, so refer to the manufacturer’s instructions for guidance. Use roofing screws or nails to secure the metal sheets in place, ensuring they are tightly fastened to the roof deck.

Step 3.2: Finishing Touches

Once all the metal sheets are installed, it’s important to add finishing touches to ensure a professional and weather-resistant installation. This includes installing metal ridge caps to cover the peaks of the roof and prevent water penetration. Use roofing screws or nails to secure the ridge caps in place, making sure they are aligned properly with the metal sheets. Additionally, seal any gaps or joints with appropriate sealant to prevent leaks and enhance the overall durability of the roof.

Overall, installing metal roofing over shingles can be a cost-effective and efficient solution for homeowners. By following these steps and taking the necessary precautions, you can enjoy the benefits of a durable and stylish metal roof while saving time and money on the installation process.
