Can You Install a Metal Roof Over Shingles in Florida? Here’s What to Know

If your roof is aging but the structure is still solid, a metal roof overlay could be your smartest move. Instead of tearing off the old shingles, we install the new metal roof right over them. At Roof Nuts FL, we help homeowners across Jacksonville, Tampa, and the rest of Florida save time and money with this efficient roofing solution.

Here’s what to know before going with a metal-over-shingle installation.

What Is a Metal Roof Overlay?

A metal roof overlay is when we install a new metal roofing system directly over your existing shingle roof. This is allowed in Florida as long as:

• There’s only one layer of existing roofing

• The decking is in good condition

• The structure meets local wind uplift codes

It’s a great option for homeowners who want the benefits of metal without the mess and cost of a full tear-off.

5 Reasons Florida Homeowners Choose Metal Overlays

1. Faster Installation

• Skipping tear-off cuts days off the project timeline.

• Less labor means less disruption to your home.

2. Lower Cost

• No dump fees for removing shingles.

• Less labor and disposal equals more savings.

3. Extra Insulation

• Existing shingles add a layer of thermal and sound insulation.

• Can reduce noise and improve energy efficiency.

4. Less Risk to Your Home

• Your roof stays protected during installation.

• No chance of exposed decking during Florida’s unpredictable weather.

5. Hurricane-Ready

• We use 4-way interlocking metal panels and proper fasteners.

• Meets Florida Building Code for wind resistance up to 140+ mph.

When Is a Metal Overlay NOT Recommended?

A metal roof overlay may not be the right option if:

• There are multiple shingle layers

• Your roof deck is rotted or damaged

• The existing roof has poor ventilation or insulation

In these cases, a full tear-off and replacement is the better long-term solution.

FAQs

Is a metal roof overlay legal in Florida?
Yes, as long as there’s only one layer of roofing and your structure meets local code.

Will it look bulky?
No. Metal panels are thin and low-profile. Most people can’t tell the roof was installed over shingles.

Can I walk on a metal roof overlay?
Yes, but always with caution. The existing shingles beneath provide some extra support.
