Issues You Might Encounter

When installing metal roofs over shingles, you might encounter a few issues. The first issue you might encounter is how to cut the metal for an overhead ridge vent that will be installed on top of shingles; since cutting a hole in your roof can often lead to leaks, place the vent over a section of shingles and attach it with screws from below without piercing through them. You'll also encounter issues on installing a metal roof over shingles in how you attach the corners of the panels together. Other issues that you might have during the installation process might include how to secure the metal panels on top of your shingles, how to seal a seam between two pieces of metal roofing, and how you should attach flashing.

To avoid such issues, you are highly recommended to seek the help of a professional like Shield Roofing and Sheet Metal to assist you in installing a metal roof over existing shingles.

Step-by-step Guide

STEP 1: Get a precise measurement of your roof surface

To avoid issues, you should get a precise measurement of the roof surface. Once you have this, measure how much metal will be needed for a perfect fit. The last thing that you want is to run out in the middle and not know how to fix it!

STEP 2: Lay down roofing felt over the entire roof

Upon getting a precise measurement of your roof surface, you can lay down roofing felt over the entire surface. This will help protect your roof from any damage that may occur during installation.

STEP 3: Start putting the metal panels into place

The next step is to start putting the metal panels into place. You want this type of installation because it will last much longer than shingles and be less of a hassle in the long run.

STEP 4: Install rubber or foam closure strips

Once the metal panels are in place, the next step is to install rubber or foam closure strips. This will help prevent any water from entering the joint and damaging your home's interior.

STEP 5: Attach the ridge cap

Once you install the rubber or foam closure strips, the next step is to attach the ridge cap. Usually, a metal roofing installer will make this for you and get it professionally cut and installed on your roof before starting work. You can also get it installed by yourself; however, it's typically more expensive to do so.

Safety

It is essential to wear the appropriate safety gear when installing a metal roof over shingles.

●      Safety goggles to protect your eyes from any small particles or dust that may be in the air.

●      Gloves and long sleeve shirt/long pants if you are going to handle hot surfaces like molten aluminum, magnesium, etc.

If not handling these materials, wear gloves to protect against cuts from sharp objects on site (nails, wire mesh).

It is also essential to install metal roofs to not become power hazards by touching electrical wires. High voltage lines can cause fires when contacted with an energized conductor - contact local authorities before operating near power lines!
