Switching From Shingle to Tile or Metal: What Changes on Your Roof

Can your home carry tile or metal? Weight and structure

The biggest difference between the three materials is weight, and it's the first thing to sort out.

Metal is the lightest of the three. Most metal roof systems weigh less than the shingles they replace, so a home built to carry shingles can usually carry metal without structural changes.

Tile is a different story. Concrete and clay tile weigh much more than shingles. That doesn't rule tile out, but it does mean the roof framing has to be up to the job. Neal's team checks the structure during the estimate, so you'll know whether your home is ready for tile before you choose one.

Before

After

Why does this matter so much? A home's roof framing was designed around the roof it was built with. Moving to a lighter roof asks nothing extra of that framing. Moving to a heavier one asks it to carry more weight every day for the life of the roof, so it's worth confirming the framing can do that comfortably.

If tile is your goal, it's better to learn this early, before you've picked a color or a profile.

What happens to your roof deck

The roof deck is the layer of wood sheathing your roof sits on. When you switch materials, the old shingles and underlayment come off, so the deck is exposed.

That's a good thing. It's the one time you get a clear look at the deck. On an older home, the original deck fastening may not match what today's Florida code expects for a replacement. Our crew will check the deck and re-nail it where needed before the new underlayment goes on. That way the new roof starts on a solid, well-fastened base, whichever material you choose.

Underlayment, flashing and edges change too

The underlayment is the layer between the deck and the finished roof, and it's not one-size-fits-all. Florida's building code sets separate requirements for each roof covering, so a tile roof and a metal roof each get their own underlayment and installation details.

The trim changes too. Flashing at walls, valleys and chimneys, along with the metal at the roof's edges, is shaped and installed to suit the new material. Tile roofs have their own edge and ridge details. Metal roofs use trim made to work with the panels. Your proposal should describe these details for the material you choose, not just the material on top. This is also where workmanship shows most. Careful flashing at walls, valleys and roof edges is a big part of how well any new roof performs over the years.

Permits and HOA approval

A full roof replacement generally needs a building permit from your city or county, and inspectors check the work along the way. Your roofer should pull the permit and schedule the inspections. In many areas, an inspector checks the work partway through, often once the new underlayment is on, and again when the roof is finished. In Florida, roofing products, including tiles, metal panels and underlayments, also have to be approved for use under the state's product approval rules.

If you live in a community with an HOA, changing materials usually needs the association's approval first. Florida law lets an HOA review a home's exterior appearance to the extent its governing documents allow, and many associations keep lists of approved roof materials, profiles and colors. Check your HOA's rules early, before you settle on a look. Many associations ask to see the material, profile and color you plan to use, so have those details ready when you apply. Your roofer can help you gather the product information the HOA needs.

Timeline: what to expect

Every home is different, so your proposal should lay out the expected schedule for your roof. In general, a switch follows these steps:

1. Estimate and structure check. During your estimate, we look at your roof, talk through materials and check the structure.
2. Approvals. Your HOA approves the new material, if needed, and the permit is issued.
3. Tear-off and deck check. The old roof comes off, and the crew will check the deck and re-nail it where needed.
4. New underlayment and roof. The underlayment, flashing and new tile or metal go on.
5. Inspections and cleanup. Inspections are completed, and the site is cleaned up.

Tile and metal installs usually take longer than a shingle replacement. Throughout the job, you'll get photo updates, so you can see the progress even when you're not home.

Tile or metal: a quick way to decide

If you're still choosing between the two, these questions can help:

• Do you love the classic Mediterranean look? Tile is a natural fit, as long as your structure checks out.
• Do you want the lightest roof, with no structural changes? Metal is the simpler switch.
• Does your HOA limit your options? Start with its approved list.
• Do you live close to salt water? Ask how the metal parts of either roof are chosen for the coast.

Paying for the upgrade

Tile and metal are premium materials, and many homeowners prefer to spread the investment over time. Roof financing is available, subject to credit approval.
