Metal Roof Over Shingles?
Metal roofs are a symbol of durability, energy efficiency, and lasting beauty. They're a dream come true for many homeowners. But what if your dream home already has a shingle roof? While installing a metal roof directly over your existing shingles might seem like a quick fix, it can lead to hidden problems that turn into a costly headache down the road.
Why Skipping Shingle Removal Can Be a Costly Mistake
Here's why experts strongly advise against installing a metal roof over shingles:
- Building Code Violations: There can only be so many layers of roofing in Florida. In some cases, there may already be two layers. If this is the case you cannot add any more roofing layers. Sometimes it is difficult to tell if there are multiple layers without tearing off.
- Uneven Surfaces: Without tearing off it is difficult to fix uneven surfaces. When there are uneven surfaces or imperfections in the deck this can cause oil canning. This is not the aesthetic you are going for when we install a metal roof.
- Nailable Substrate: Without tearing off there is no way to tell the deck's condition. When nailing into a deck that is rotten or weakened in any way this can compromise the structural integrity of the roof.
- Reduced Longevity: Metal conducts heat and cold more readily than shingles. Trapped moisture between the layers can cause condensation, leading to rust, mold growth, and premature deterioration of both the metal roof and your underlying shingles.
- Warranty Woes: There are some manufacturers that do not want to offer warranties on these roof overs. It can be difficult in some cases to meet their install requirement to get the warranty
The Better Way: A Long-Term Investment
For a successful and long-lasting metal roof, removing the existing shingles is the best course of action. This allows for a thorough inspection of the roof deck, proper ventilation installation, and a clean, secure base for your new metal roof.
