How to Install Metal Roofing in Toledo, Ohio

Most Toledo homeowners who search how to install metal roofing aren’t picking up a drill. They want to know what a good crew does on the roof, so they can spot a bad install before it leaks. These are the steps we follow.

We’re a Roser Certified installer and a Decra Partner in Quality, and our own crews handle every metal roofing installation in Toledo. Here’s the job from tear-off to ridge cap.

Step 1: Tear Off the Old Roof and Check the Deck

A metal roof over shingles can trap moisture and hide soft decking, so we strip the old roofing down to the deck on every metal roof installation. Toledo’s freeze-thaw cycles work on trapped moisture all winter.

With the deck bare, we check every sheet and photograph soft spots, stains, and gaps. Bad decking shows up as waves under metal panels, so we show you what we find and price any repair before we do it.

Step 2: Lay Metal Roof Underlayment and Ice and Water Shield

Underlayment made for metal roofing goes down first. The felt and asphalt-rated synthetic used under shingles breaks down under hot metal panels, and cold panels collect condensation on their underside in winter.

Ice and water shield runs along every eave, at least 24 inches inside the exterior wall line, and through the valleys and around penetrations. The drip edge goes on in the order the panel maker specifies.

Step 3: Lay Out the Panels and Set the First One

The first panel sets the line for the whole roof, so we snap a square reference line before it goes down. A panel that starts crooked drifts further with every panel after it.

Panels are cut to the length of each slope, eave to ridge when we can, to avoid seams. We cut them off the roof, trim the burrs, and sweep up metal shavings, which rust and stain the finish.

 

Step 4: Standing Seam Metal Roof Installation

Standing seam panels lock together along raised seams, with concealed clips holding them down. There are no exposed screws, so there are no rubber washers to dry out and leak later.

The panels also move on those clips as temperatures swing. We set clip spacing and seam engagement to allow for it, since a panel fixed too tight creaks and strains its seams. This is the part Roser certification covers.

Step 5: Stone-Coated Metal Roofing Installation

Decra stone-coated steel goes on in courses from the eave up. Each panel overlaps the one below and is nailed through its top hem. From the street it looks like shingles, but the steel base installs differently.

As a Decra Partner in Quality, we hold the course offset and overlap depth the system calls for. We tie the panels tightly into the valleys, chimneys, and penetrations.

Step 6: Metal Roof Flashing, Valleys, and Trim

Metal roof flashing isn’t asphalt flashing. A chimney on a standing seam roof needs step flashing that works with the clips, and a metal roof valley needs a pan that matches the panel profile.

Pipe boots have to flex as the panels expand and contract. We make the flashing for each roof and photograph it before the panels cover it. Request a free metal roofing quote or call 419.475.9600.

 

Step 7: Metal Roof Ridge Cap and Ridge Vent

The ridge cap closes the top of the roof. On standing seam it uses the same concealed fasteners as the field panels, and stone-coated systems use matching ridge and hip pieces.

A metal roof ridge vent needs a baffled design so wind-driven rain and snow stay out. Before we install it, we check the attic’s ventilation against the roof maker’s requirements.

Toledo Permit for Metal Roof Installation

The City of Toledo requires a permit for a roof replacement with a complete tear-off in a one, two, or three unit home. The city says a homeowner who hires a contractor doesn’t apply, and the contractor does.

We handle the permit, and the fee is in our written estimate. You can see the full range of our metal roofing services in Toledo or our wider roof replacement work.

Can You Install Metal Roofing Yourself?

A skilled homeowner can put a corrugated, exposed-fastener metal roof on a shed or garage. A house is different. Standing seam needs seaming tools and a careful clip layout, and a fall from a metal roof is serious.

Stone-coated and standing seam systems also carry manufacturer warranty conditions tied to who installs them, and a permit applies either way. If you’re weighing it, we’ll walk you through the job before you decide.

Questions to Ask Before You Sign a Metal Roofing Contract

Ask which metal roofing certifications the contractor holds, because shingle certifications don’t cover metal. Ask what underlayment goes under the panels, and how the crew sets clips and handles thermal movement at the ridge.

We answer each one in writing before you sign. We’re Roser Certified and a Decra Partner in Quality, we use our own crews on every job, and we’ve held a BBB A+ rating since 2005. Call 419.475.9600 or get a free metal roofing assessment. Financing is available as low as $99 a month.

Frequently Asked Questions

Can you install metal roofing over existing shingles?

Sometimes, but we don’t do it on Toledo homes. Old shingles trap moisture under the panels and hide soft decking, and Toledo’s freeze-thaw cycles stress the attachment every winter. We tear off to the deck and put the panels on a clean, inspected surface.

How long does metal roof installation take?

Most Toledo homes take one to three days. A simple roofline with few penetrations goes faster, and a roof with several dormers, chimneys, or deck repairs takes longer. We tell you about any timeline change before the install date.

Do you need underlayment under a metal roof?

Yes. We use a synthetic underlayment made for metal roofing, with ice and water shield along the eaves, in the valleys, and around penetrations. Felt paper and asphalt-rated underlayment aren’t built for the heat and condensation under metal panels.

What fasteners are used to install a metal roof?

It depends on the system. Standing seam panels are held by concealed clips. Corrugated panels use screws with rubber washers along the ribs. Decra stone-coated panels are nailed through the top hem of each course.

What is the difference between standing seam and exposed fastener metal roofing?

Standing seam hides its fasteners under raised seams and moves on clips as temperatures change. Exposed fastener panels are screwed through the surface, so their washers need checking over the years. Our guide to standing seam vs corrugated metal roofing goes through the differences.

Do you need a permit to install a metal roof in Toledo?

Yes, for a roof replacement with a complete tear-off in a one, two, or three unit home. The City of Toledo says the contractor applies when you hire one. We handle the permit and include the fee in the written estimate.

How much does metal roof installation cost in Toledo?

Most metal roofs we install in Toledo cost $25,000 to $35,000. Where yours lands depends on the size and pitch of the roof, how many valleys and chimneys it has, and whether any decking needs replacing. Your free written estimate lists every cost, and financing is available as low as $99 a month. See our guide on whether metal roofs cost more than shingles.
