Three Tips To Help With Installing Metal Roofing Panels Over Existing Shingles

by Lorraine Fisher

If you have an asphalt shingle roof, you may want to replace it with metal. Roofing panels can be a great option that will last for years. Metal roofing can even be installed over existing shingles to help reduce the cost of removal and protect your home from leaks. If you are planning on installing metal roofing over an existing asphalt shingle roof, here are some tips to help you with the installation:

1. Add Felt Paper For Addition Moisture Barrier

When installing metal roofing on shingles, the old roofing can often be left in place. It is damaged, this can leave it exposed to leaks. It can also cause the surface to be uneven for the metal roofing. You may want to consider installing felt paper or a rubber membrane over the shingles. This will help to give your home more protection from leaks, as well as make the surface smoother for the installation of the metal panels.

2. Install Nailers To Reduce Leaks And Add Air Space

Nailers can be installed to fasten the metal roofing to your home. These are boards that are nailed on the existing roof to provide something to nail to. The nailers will make it easier to install the panels and ensure that they are well fastened. It will also help provide a gap between the metal roofing and your existing roof. This can help to allow air to flow and reduce energy loss in your home. In warmer climates, this can help reduce the heat gain caused by metal roofs during the hot summer months.

3. Use Ventilation To Improve Energy Efficiency Of Metal Roofing

Ventilation is also important, which you will want to have the common roof vent systems in place. If you have a space between the old shingles and new roof, it is a good idea to also have ventilation at the bottom of the roof and at the ridge. This will allow air to flow freely beneath the new roofing, and prevent problems with moisture and humidity building up beneath the metal panels. You may want to leave gaps between nailers to allow air to flow where you have vents installed on your roof.

These are some tips to help you with the installation of metal panels on asphalt shingles. If you need help with the installation of metal roofing, contact a roofing contractor (such as Amick Roofing Inc) and talk with them about the best options for the needs of your home.
