Why You Should Remove Your Existing Shingles Before Installing a Metal Roof
If you’re looking to install a metal roof on your home, then it is important that you remove any existing shingles before beginning the process. While this may seem like a daunting task, it is essential for ensuring that your new roof is properly and securely installed.
Keep reading to learn why removing existing shingles is so important when installing a metal roof!
Why You Should Remove Existing Shingles
One of the primary reasons for removing existing shingles before installing a metal roof has to do with stability. Metal roofs are much heavier than traditional asphalt shingles, and having multiple layers of material can significantly decrease the stability of your roof. Removing the existing shingles ensures that your metal roof will be as secure as possible once it is installed.
In addition to decreasing overall stability, not removing existing shingles can lead to potential issues down the line. When two different materials are installed together, they will expand and contract at different rates depending on temperature and weather conditions.
This means that even if you have removed all nails from the old shingle layer, over time the two materials can start to separate or pull away from one another due to different expansion rates. This can cause gaps in between the layers or even damage your new metal roof in some cases.
Finally, failing to remove existing shingles before installing a metal roof can also lead to problems with ventilation and moisture buildup in your attic space. Without proper ventilation, heat and moisture can become trapped within your attic leading to mold growth or dry rot which could damage not only your new metal roof but also other parts of your home over time.
Additionally, without proper ventilation condensation from outside moisture can build up under the layer of old shingles leading to leaks in both the old and new layers of material.
Conclusion:
Removing any existing shingles before installing a metal roof is essential for ensuring that it is properly secured and free from potential issues down the line.
Doing so will ensure increased stability as well as proper ventilation which helps prevent issues such as mold growth or dry rot in your attic space caused by heat or moisture buildup over time.
Taking these steps prior to installation will help ensure that you get maximum value out of your new metal roof!
