Yes, you can install metal roofing over asphalt shingles. This method, called an overlay, allows homeowners to add a new metal roof without removing their old shingles. However, there are important considerations before proceeding. Indiana Metal Roofing Systems provides comprehensive roofing solutions in Fort Wayne and ensures your roof installation is done correctly. Indiana Metal Roofing Systems offers expert insights and installations that guarantee your roof’s longevity.
What is a Metal Roof Overlay?
A metal roof overlay involves installing a metal roof directly over an existing asphalt shingle roof. This is typically done when the asphalt shingles are in good condition, and homeowners want to upgrade to the durability of metal without the added cost of removing the old roof. While overlays save time and money upfront, they are not always the best option in the long term.
Fun Fact: Metal roofs last up to 50 years or more, making them one of the longest-lasting roofing materials available today!
When is an Overlay a Good Idea?
A metal roof overlay is suitable in specific situations:
The asphalt shingles are in good condition with no visible damage.
There are only one or two layers of roofing material already in place.
The roof’s structure is strong enough to support the additional weight of a metal roof.
Before proceeding, it's crucial to have a professional roof inspection to assess whether your existing roof can handle the added weight of a metal overlay.
Pros and Cons of Installing Metal Roofing Over Shingles
Pros
Cost Savings: Installing metal over shingles is cheaper than a full roof replacement since there is no need to remove the existing roof.
Quick Installation: The overlay process is faster and requires less cleanup.
Additional Protection: By adding another layer of roofing material, you get extra coverage from the elements.
Cons
Can Only Be Done Once: If you need another roof replacement, the extra layers will make the process more complicated and costly.
Underlying Damage May Be Missed: Without removing the old shingles, underlying issues like rot or mold may go unnoticed.
Weight Concerns: Adding a metal roof on top of shingles increases the overall weight on the roof, which may not be suitable for older homes.
Less Visual Appeal: While metal roofs are visually striking, installing them over old shingles may not offer the cleanest look.
Alternatives to Metal Roof Overlays
In some cases, a full roof replacement is a better option. Removing the old shingles allows for a thorough inspection of the roof’s underlayment and deck, ensuring no hidden problems are left unaddressed. This option also provides better long-term durability and a cleaner aesthetic.
