Standing seam metal roofs are a major investment for any homeowner — and when they’re installed correctly, they’re absolutely worth it. They’re beautiful, energy efficient, durable, and can last for decades. But when they’re done wrong? They can be a nightmare.
At Roofer Chicks®, we’re often asked why our metal roof bids come in higher than some of our competitors. The short answer: we don’t cut corners. We believe in doing it right the first time, backing every installation with our Lifetime Workmanship Warranty, and protecting your investment for the long haul.
Let’s walk through what makes a standing seam metal roof such a smart choice — and what to watch for when comparing bids.
Tear-Off & Decking
We always tear off everything — shingles, underlayment, the works — to expose the decking. That’s the only way to see if there’s hidden damage from leaks, rodents, or improper construction.
Some roofers try to install new metal over old materials, but that’s asking for trouble. A clean, solid deck is the foundation of a long-lasting roof.
Older homes may have thinner 3/8” decking (today’s code requires 7/16”). Depending on where you live, a redeck might be required — it adds cost but dramatically improves stability, sound resistance, and energy efficiency.
We sometimes install retrofit systems over old metal roofs (never shingles). These use purlins to create an air pocket between the old and new roof for better ventilation and insulation.
Underlayment
Even the smallest details matter. The wrong fasteners can leave tiny imprints under metal panels, so we use the right materials and handle every stage carefully to protect your finish.
Metal Panels & Gauges
We typically install 24-gauge panels, which strike the perfect balance between strength and flexibility. (Remember: the lower the number, the thicker the metal.)
Cheap 29-gauge panels — the kind you find at home-improvement stores — dent easily and don’t hold up in Central Texas wind or hail.
Seams
There are three main seam types: single lock, double lock, and snap lock.
- Double lock seams are folded twice for superior waterproofing.
- Snap lock seams snap into place quickly and can be easier to repair later.
Each has its place, but we typically recommend double lock seams for durability and water resistance in Hill Country weather.
Fasteners & Clips
Hidden fasteners are what make standing seam roofs so clean and low-maintenance. We use manufacturer-made clips(not homemade) and proper fasteners that penetrate the deck.
This allows the panels to “float” slightly during temperature changes, preventing stress and keeping your roof secure during storms.
Panel Profiles
We roll-form panels on site for a custom fit. Our profiles include flat, pencil-rib, and striated. Flat panels look sleek but highlight imperfections; striated panels hide them beautifully.
If you’ve ever heard of oil canning (those wavy reflections on flat metal), it’s often caused by uneven decking or fastener placement — something we minimize through careful prep or backer-rod support when needed.
Flashings, Crickets & Trim
Flashing is what keeps water out where the roof meets other surfaces. We custom-bend all flashing in our shop (not on site) from the same metal as the panels.
Every chimney wider than 28” gets a cricket (also called a saddle) to divert water and debris.
We use z-closures under hip and ridge caps for a watertight finish.
Valleys & Penetrations
Valley metal must be wide enough to handle backed-up water during heavy storms. We add ice and water shield for extra protection.
For plumbing vents, we use neoprene pipe boots like Dektite — they’re flexible, UV-resistant, and safe for Galvalume. Lead or aluminum boots may corrode or rely too heavily on sealant, which eventually breaks down in the Texas sun.
Ventilation & Curbs
Metal roofs still need proper ventilation — ridge vents, power vents, or solar vents can all work. Fewer penetrations = fewer leak points, so we often recommend a single power vent instead of multiple static vents.
Larger penetrations (like skylights or solar vents) are built on curbs, which allow for proper flashing and easier maintenance down the road.
The Limits of Metal
A standing seam roof is tough, but not indestructible.
If a hailstorm dents your car, it’ll probably dent your roof too — but that doesn’t mean it’s failing. Most hail dents are cosmetic.
Still, insurance companies can be tricky. Many call dented metal “cosmetic damage” and won’t cover replacement unless there’s functional harm.
Warranties & Repairability
Unlike shingles, most metal manufacturers don’t offer material warranties. Your workmanship warranty is what really matters.
Roofer Chicks® has been around since 2016, and we stand behind our work for life.
Our Lifetime Workmanship Warranty means we’ll fix it if we did it — period.
Standing seam roofs are notoriously hard to repair (you can’t just swap out a single panel), so quality installation matters from day one.
The Bottom Line
A standing seam metal roof is an incredible investment in your home — when it’s installed right.
At Roofer Chicks®, we don’t take shortcuts. We install every roof to code (and then some), and we stand behind it for life.
If you’re in New Braunfels, Central Texas, or the Hill Country, and you’re considering a metal roof, give us a call. We’ll walk you through your options and show you what “done right” really looks like.
