Thinking about upgrading to a metal roof? Great choice! A metal roof installation offers durability, energy efficiency, and a sleek, modern look. But not all metal roofs are created equal. This guide will walk you through everything you need to know—especially the differences between standing seam panels and corrugated sheets, cost breakdowns, timeline expectations, and certified techniques.
We’ll also explore common questions, key materials like fasteners, underlayment, and insulation layers, and expert advice to help you choose the right system for your home or business.
Why Choose Metal Roofing?
A metal roofing installation can last 40 to 70 years, making it one of the most long-term roofing options available. It’s ideal for both homes and commercial buildings, offering:
- High durability against wind, fire, and hail
- Excellent energy efficiency with reflective coatings
- Resistance to mildew, pests, and rot
- Sleek aesthetics with modern or rustic looks
You’ll find options like steel roof installation, tin roof installation, and coated aluminum among others. Manufacturers like EDCO, DECRA, McElroy Metal, and Classic Metal Roofing offer plenty of choices.
Standing Seam vs. Corrugated Metal Roofing
Let’s compare the two most popular options:
Standing Seam Panels
- Hidden fasteners (no screws exposed)
- Clean, modern look
- Often used in residential and commercial projects
- Costs more but lasts longer with fewer maintenance issues
Corrugated Metal Sheets
- Exposed fasteners (visible screws)
- Budget-friendly
- Classic and rugged style
- Requires routine inspection of fasteners and sealants
ATAS International and Fabral are top producers of both panel styles. Your choice will depend on your budget, roof pitch, and long-term expectations.
If you’re investing in a metal roof replacement, understanding proper roof installation techniques will ensure optimal performance and longevity.
How Much Does a Metal Roof Cost to Install?
Metal roofing isn’t cheap—but it pays off over time. Here’s what to expect:
- Corrugated Panels: $4 to $8 per sq. ft.
- Standing Seam Panels: $8 to $14 per sq. ft.
- Additional costs: underlayment, flashing, snow guards, labor, and disposal
The final price can vary based on:
- Roof size and pitch
- Labor costs in your area
- Chosen metal type (galvanized steel, aluminum, copper)

Installation Timeline: What to Expect
Most metal roofs take 2 to 5 days to install. However, larger or more complex roofs may take a week or more. Here’s a general breakdown:
- Tear-off (if needed): 1 day
- Prep work: Install underlayment & insulation
- Panel installation: 2–3 days
- Detailing: Flashing, ridge caps, snow guards, and cleanup
Incorrect slope during flat roof installations often leads to ponding water repairs within 2–3 years.
Can You Install a Metal Roof Over Shingles?
Yes, it’s possible. Metal roofs are lightweight enough to be installed over existing shingles, provided:
- The existing roof is flat and not damaged
- Building codes in your area allow it
- Additional furring strips or underlayment are added to prevent moisture issues
That said, a full tear-off is usually better for inspecting decking and applying new flashing.
While replacing roof shingles can be a temporary fix, a full roof installation may be necessary if underlying damage is found.
How to Prepare for a Metal Roof Installation
Here’s how to make the process smooth:
- Clear your attic and move fragile items
- Remove vehicles from the driveway
- Inform neighbors of potential noise
- Confirm dumpster placement and staging areas with your contractor
This is especially important for commercial roof replacement jobs where downtime matters. For businesses considering a commercial roof replacement, proper roof installation is key to minimizing downtime and maximizing durability.
Homeowners planning a residential roof replacement should review best practices for new roof installation to avoid common pitfalls.
What’s Involved in the Installation Process?
Materials Used
- Underlayment: Usually synthetic or felt, laid before panels
- Fasteners: Corrosion-resistant screws with rubber washers
- Sealants: For seams and joints to prevent leaks
- Insulation: Optional for added energy efficiency
- Flashing & Snow Guards: Protect edges and manage snow buildup
Certified Roof Installers
Use certified installers trained by manufacturers. Check for Metal Roofing Alliance (MRA) membership or factory certification. You can also search metal roof installers near me for trusted local pros.
Are Metal Roofs Noisy or Hot?
Let’s clear this up:
Are They Noisy?
Not with proper insulation. When installed correctly, metal roofs aren’t louder than shingles during rain or hail.
Do They Make Your Home Hotter?
Actually, no. Most metal roofs have Energy Star rated coatings that reflect sunlight, reducing heat absorption and lowering your AC bill.
How Long Does a Metal Roof Last?
- Corrugated panels: 30–50 years
- Standing seam panels: 40–70 years
- Copper or zinc systems: Up to 100 years
Routine inspection and re-sealing of fasteners can extend lifespan, especially for exposed systems.
