Yaocom 20 Pcs Metal Roofing Panels 43.3" x 17.72" Corrugated Galvanized Steel Roof Panels Metal Siding Panels with Screws 106 Sq.ft Gazebo Top Cover for Pergola Patio Garden Mobile Home, Black

Why I chose the Yaocom panels for small structures

I needed a lightweight, easy-to-handle roofing option for a backyard pergola and some siding for a small garden shed. Traditional 26–29 gauge roofing would have been overkill (and heavy) for those projects, and cutting long sheets on sawhorses in a tight yard is never fun. The Yaocom panels—short, corrugated galvanized sheets with a black finish—fit the brief: manageable size, DIY-friendly, and a clean look.

Each panel measures 43.3 by 17.72 inches, and the kit ships with 20 panels and a bag of screws. On paper, that’s about 106 square feet of coverage. In practice, your coverage will be less once you account for side-lap and end-lap. Still, for pergolas, lean-tos, chicken coops, and small outbuildings, this set hits a convenient sweet spot.

Build quality and finish

At 0.01 inches thick, these are thin steel panels—roughly in the realm of 30–31 gauge. That’s intentional. The thin stock keeps weight low and makes bending and cutting straightforward, which is perfect for small structures where you don’t need structural roofing. The galvanization offers baseline corrosion resistance, and the black topcoat (painted finish) adds a bit more protection while delivering a modern look that pairs nicely with most backyard builds.

A few practical notes from use:
- The finish is reasonably durable for DIY handling, but it will scratch if dragged across rough surfaces or cut with a grinder. I had better results cutting with aviation snips and a nibbler to protect the coating.
- As with any galvanized panel, cut edges are more susceptible to rust over time. I hit my cut lines with a cold galvanizing spray and a touch-up of black paint to be safe.
- The corrugation is consistent panel-to-panel, which made alignment and side-lap straightforward.

Size and coverage: plan your overlaps

The headline coverage (about 106 square feet for 20 panels) assumes no overlap. In real installations:
- Side-lap: I overlapped by one corrugation.
- End-lap: I used a 6-inch overlap on a low-slope pergola bay and 8 inches on a very shallow section.

With those overlaps, my effective coverage was closer to 90–95 square feet for the set. If your roof pitch is very shallow or you’re in a windy area, be conservative and plan even more overlap. Because each panel is only 43.3 inches long, multi-row installations will have more seams than full-length roofing sheets—perfectly fine for light-duty applications, but something to factor into layout and waterproofing.

Installation experience

These panels are about as DIY-friendly as metal roofing gets. A few things that worked well for me:

• Layout and supports: I ran purlins at 16 inches on center to keep the thin panels supported and avoid oil-canning. If you go wider, expect some flex and a noisier roof in the rain.
• Cutting and shaping: Snips were my go-to for trimming length and notches; a nibbler made quick work of side cuts. The panels are bendable enough to conform to slight curves or create drip edges, but keep bends gentle to avoid kinking.
• Fasteners: The kit includes screws. For roofing, I supplemented with additional roofing screws with EPDM washers to hit every purlin and secure the overlaps. On corrugated profiles like this, I prefer driving screws at the crest for roofing applications to keep water out, and at the valley for vertical siding.
• Overlaps and sealing: One-corrugation side-lap worked well. I added a bead of butyl tape under end-laps on the low-slope section. Foam closure strips at eaves and ridges help keep out wind-driven rain and pests; these aren’t included but are worth sourcing to match the profile.
• Drilling and driving: Pre-drilling through two overlapped panels kept holes clean and reduced paint chipping. Drive screws snug—don’t over-compress washers.

With two people, I installed a 100-square-foot pergola cover in an afternoon, including cutting and trim. Working solo is doable thanks to the short length and low weight.

Performance in weather

On the pergola and shed, the panels handled a couple of blustery, rainy days without issues. Proper overlap and enough fasteners are the key. A few performance observations:

• Water management: With a reasonable pitch and sealed end-laps, I saw no leaks. On very shallow pitches, I’d recommend stepping up end-lap sealing and being meticulous with fastener placement.
• Wind: Thin panels are only as wind-ready as your fastening pattern. The six screws per panel notion is light for roofing; I used more to tie into each purlin and lock down seams. Installed this way, the panels stayed put through gusty conditions common in my area.
• Noise and heat: Rain is noticeable on any metal roof, and thin panels are louder. Underlayment or even a layer of corrugated plastic under the steel can soften the sound. The black finish absorbs heat; in full sun, the panels get warm and can raise temperatures beneath a pergola. The trade-off is low glare and a sharp look.

Use cases and limitations

Where these panels shine:
- Pergolas, gazebos, lean-tos, and patio covers
- Sheds, chicken coops, and small outbuildings
- Vertical siding and windbreaks
- Temporary or seasonal structures

Where I’d think twice:
- High-wind zones or open exposures without upgrading fastener count and overlap strategy
- Heavy snow loads—these are not structural roof panels
- Coastal environments—galvanized steel will corrode faster in salt air; consider aluminum or a heavier galvalume option
- Walkable roofs—this gauge dents easily and isn’t meant for foot traffic

Practical tips to get the most from the panels

• Plan coverage with overlaps in mind. Sketch the layout, mark purlin lines, and calculate end-lap loss before you cut.
• Use closure strips and butyl tape at critical seams to improve water resistance.
• Add fasteners. Hitting every purlin and locking down overlaps makes a big difference in wind and rattle.
• Cut with snips or a nibbler to protect the finish. If you use a grinder, expect to touch up edges.
• Touch up cuts and scratches with a galvanizing primer and black paint.
• Wear gloves—the cut edges are sharp—and eye protection when cutting.

Durability and maintenance

For light-duty use, these panels should hold up well. The galvanization plus painted finish is a solid combination against rain and sun. Periodic checks help: look for lifted screws, chipped edges, or accumulated debris at overlaps. If you keep edges touched up and fasteners snug, the panels should provide several seasons of reliable service on small structures. I store leftover sheets flat and dry to avoid white rust.

Value

You get 20 panels and a bag of screws in one box, which is convenient for small projects. The manageable size reduces waste—you’re less likely to have big offcuts compared to full-length roofing sheets. While heavier-gauge panels will outlast these in harsh conditions, they come at a higher cost, require more robust framing, and are harder to DIY. For backyard builds, this kit hits a practical price-to-performance balance.

Recommendation

I recommend the Yaocom panels for light-duty roofing and siding projects where ease of handling, simple installation, and a clean look matter more than maximum strength. They’re a smart choice for pergolas, sheds, and similar structures if you plan overlaps carefully and use enough fasteners. The thin gauge, short length, and limited included hardware mean they’re not the right pick for high-wind, heavy-snow, or coastal applications without additional measures. But installed thoughtfully, they deliver solid protection, a tidy aesthetic, and a straightforward DIY experience.
