So, you’re thinking about installing a metal roof? Good choice. We’ve worked with homeowners across New York, and one thing we hear often is, “I wish I had done this sooner.” Why? Because a metal roof isn’t just tough—it’s long-lasting, energy-efficient, and actually looks pretty sharp on a home.
Thinking about swapping out your roof or just poking around at different options? This metal roofing guide’s got your back. At AKT Construction NY Inc, we’ve installed metal roofs on hundreds of homes.
We’ll spill the beans on what tools you actually need, the rookie mistakes everyone seems to make, and toss in a few tips from the trenches—so you won’t feel totally lost (or, hey, at least you’ll know if your contractor’s full of it).
No fluff, no jargon. Just the straight-up info, the way we’d explain it to a friend over coffee.
Tools & Materials You’ll Need for Metal Roof Installation
First things first—get your gear sorted. Don’t just grab whatever’s nearby and hope it works out. I’ve tried that, and it was a disaster.
If you skip getting the right stuff or use the wrong tools, things will go wrong. Take it from me – it’s a pain, and you’ll regret it.
Essential Metal Roofing Tools
Here’s what we use on-site every time at AKT Construction NY Inc:
| Tool | Use |

Best Metal Roofing Materials
When it comes to residential metal roofing, quality matters. Here’s what you need:
- Metal Panels – Steel, aluminum, or copper ,depending on your budget
- Underlayment – Synthetic or felt (we recommend synthetic for durability)
- Fasteners – Galvanized screws with rubber washers
We typically recommend standing seam panels for their clean aesthetic and durability. Not sure if metal is right for you? Explore What Is the Best Material for a Flat Roof in Brooklyn for 2025? if you’re comparing options.
Pre-Installation Checklist: Don’t Skip These Steps!
Before the panels go up, there’s some prep work. And trust us, this is where many DIY metal roof jobs go wrong.
Measuring Your Roof Accurately
Incorrect measurements can mess up your whole project—and the cost of a metal roof isn’t cheap. Double-check length, width, and slope. Use this simple formula:
Length x Width ÷ 100 = Square footage (in roofing squares)
We always measure twice, even with our years of experience.
Removing Old Roofing & Inspecting the Deck
Tear off all shingles and check for rot or weak spots. If your deck isn’t solid, your new roof won’t hold. We once had a client in Queens whose plywood had water damage—it nearly collapsed when we walked on it. Fixing it first saved them from a total roof failure.

Installing Drip Edge & Roof Underlayment
Drip edge helps water flow into the gutters, not under your roof. Then lay your underlayment from the bottom up, overlapping each row. This step protects against leaks—especially in New York winters.
Step-by-Step Metal Roof Installation Guide
Here’s where we get to the heart of it—how to install a metal roof from start to finish.
Step 1: Installing the Starter Strip
This is the base for your panels. It keeps them aligned and stops wind from getting under the edges. Make sure it’s level.
Step 2: Laying Metal Panels Correctly
Overlap each panel by one ridge and align it straight with the edge. A chalk line helps here. At AKT Construction NY Inc, we always triple-check panel alignment because once it’s screwed in, it’s not easy to fix.
Step 3: Securing Panels with Screws
Use screws at each rib and avoid overtightening, which can warp the panels. We see this mistake often on DIY metal roofs. A good rule? Tighten until the washer slightly compresses—no more.
Step 4: Adding Flashing Around Vents & Chimneys
Water always finds the weakest point, and this is it. Flashing must go under the panel above and over the panel below. Caulk well.
Step 5: Installing Ridge Caps for a Finished Look
This covers the peak and gives a clean look. It also helps air to flow and moisture to escape.
Pro Tips for a Flawless Metal Roof Installation
Even after hundreds of jobs, we still follow these simple rules.
Best Fastening Techniques
- Use the right screw spacing (usually every 12-18 inches)
- Don’t screw into the panel valleys—only the ridges
- Keep screws in a straight line—it just looks better
How to Cut Metal Roofing Panels Safely
Use aviation snips for small cuts and a circular saw with a metal blade for large panels. Wear safety glasses—the shards fly fast.
Preventing Condensation & Thermal Expansion Issues
Leave a gap under ridge caps for ventilation. Also, don’t screw panels too tight—they need a little room to move with temperature changes.
Metal Roof Maintenance Tips for Longevity
Metal roof benefits include low maintenance, but it’s not totally hands-off.
Cleaning & Inspecting Your Roof (Twice a Year)
We recommend checking in the spring and fall. Look for:
- Debris buildup
- Loose screws
- Damaged panels or rust
Fixing Minor Scratches & Rust Spots
Even experienced DIYers know when to call in the pros. If you’re dealing with:
- Leaks or water stains
- Soft or sagging spots
- Improper flashing
It’s time to hire a certified Roofing Contractor who knows how to do the job right.
