Considering its energy efficiency, durability, and look of metal roofs, it's natural that you want to consider metal for your roof replacement. Because roof replacements are expensive, you might wonder if it's okay to skip removing the old shingles from your roofing and just install the metal roof on top of them.
Read on to learn more about this:
When Is It Possible to Install a Metal Roof Over Shingles?
The excellent news about metal roofing is that it is lightweight and can be easily installed over top of asphalt shingles. However, the asphalt shingles must be in good condition for the installation to be successful. If the shingles are worn, there is likely water damage and aging underneath, which means that the screws used to attach the new roofing will not be secure.
It's crucial to ensure that your roof can support a metal roof before installation. This can be done by inspecting the trusses and decking for any damage or weakness.
If your roof just needs minor repairs, it may be less expensive to fix than to remove it and put on an entirely new one. You can make repairs and then put a new roof over the old one.
When Shouldn't You Put a Metal Roof Over Your Existing Shingle Roofing?
When looking at a roof replacement, there are certain situations where you should not try to save money by reusing the old roof. These situations include:
- If the old roof is not in good condition
- If the old roof is not the right type for the new roof
- If the old roof is not the right size for the new roof
- If the old roof is not structurally sound
It's usually best to replace your shingles if most of them are damaged or deteriorating. This also goes for areas of your roof that are sagging, have rotting wood, or are leaking. By replacing everything, you can be sure that your roof will be safe and sound.
A metal roof's stability depends on the foundation it is placed on. If the foundation is unstable, the metal roof will also lack stability. To ensure a safe and long lasting roof create a solid foundation for your new roof to be placed.
Conclusion
Overall, a metal roof can be an excellent option for your home, but there are some things to keep in mind before proceeding. For starters, it's important to know that a metal roof can be placed over shingles, but there are many things to consider first. The biggest thing to take note of is that the shingles must be in good condition before the new roof can be installed. Any damaged or missing shingles will need to be repaired or replaced before the new roof can be installed.
Another thing that needs consideration is the weight of the metal roof. Metal roofs are much heavier than shingles, so it's vital to ensure that your home's structure can support the weight of the roof. If you're not sure, it's always an excellent idea to consult with a professional before proceeding.
Finally, it's important to be aware of the potential for noise with a metal roof. Metal roofs can be pretty loud, particularly when it rains, so if you're looking for a roof that's going to be quiet, shingles may be a better option.
By taking your time to research and consult with a professional, you can be certain that you are indeed making the best decision for your home.
