Standing seam metal · Our specialty
Concealed-fastener standing seam metal: no exposed screws to back out, panels that move with the heat, and seam lines you can sight down. This is the work we take the most pride in.
Who this is for
Desert-modern and custom homes, hillside properties, ramadas and patio covers, barns and shops, low-slope sections, and anyone who wants a roof that outlasts the next two shingle roofs.
The detail
Standing seam is a different craft from tile or shingle. The panels are run to length, the fasteners are hidden inside the seam, and the panels are clipped so they can expand and contract as the roof swings sixty degrees between a July afternoon and a January night. Nothing penetrates the water plane. That is why a properly installed standing seam roof does not develop the slow rash of leaking screw holes that exposed-fastener panel roofs get after a decade in this sun.
It is also why the install has to be right. Panel layout has to be set before the first panel goes down so the seams land where they should and the ridge closes symmetrically. Hips, valleys and headwalls get formed metal, not sealant. Penetrations get proper curbs and boots. Eave and rake trim have to hold a straight line across sixty feet of panel — on a roof this reflective, every wave shows.
We install standing seam in the full range of finishes — matte black, bronze, tan, light and dark grays, and the deep blues you will see in our gallery — on desert-contemporary homes, poolside ramadas, hillside properties with real wind exposure, working barns and commercial buildings. We also run metal alongside tile on the same house, which is now standard on a lot of Valley new construction: panel on the low-slope and modern wings, tile on the pitched planes.
There is a practical case too. Metal sheds monsoon rain fast, it takes wind-driven debris without cracking, it reflects a serious share of the solar load off the deck, and it is one of the few residential roofs in Arizona with a genuinely long service life. It is not the cheapest roof you can buy. It is often the last one you buy.
What's included
Why our standing seam looks like that
A standing seam roof is the least forgiving surface in residential construction. It is reflective, it is uninterrupted, and every decision made before the first panel goes down stays visible from the street for as long as the roof is up.
Every clip that holds the roof down sits under the fold, behind the water plane. Nothing structural passes through the surface the rain runs across — which is the whole reason standing seam does not develop the slow rash of weeping screw holes that exposed-fastener panel roofs get after a decade in this sun.
A long panel measurably grows and shrinks between a July afternoon and a January night. Clipped panels slide with that movement. Panels pinned at both ends do not — they oil-can, they distort at the fastener, and eventually something has to give.
Hips, valleys, headwalls and skylight curbs get metal shaped to the condition they are closing. Sealant is a gasket with a shelf life, and Arizona UV finds every bead of it. If a detail on our roof is holding water out, it is because of a piece of metal, not a tube.
Panel module is set at the start so the seams run square to the ridge, the ridge closes symmetrically, and the panel at the rake is not a two-inch sliver. On a surface this reflective, a seam that wanders is visible from the driveway — so it gets resolved on the ground.

Questions about this work
Not the way people expect. Over a solid deck with underlayment — which is how we install it on a house — rain on standing seam sounds much like rain on any other roof. The barn-roof sound comes from panels over open purlins with nothing underneath.
Exposed-fastener panels are screwed through the face of the metal, so every screw is a hole in the water plane with a rubber washer holding it back. In Arizona sun those washers harden and the screws back out. Standing seam hides the fastener inside the seam, so the water plane is unbroken.
The opposite. Metal reflects a large share of solar radiation instead of absorbing it, and with the right finish and a vented assembly it puts noticeably less heat into the deck than a dark shingle roof does.
Yes, and it is common on Valley new construction and remodels — panel on low-slope and modern wings, tile on the pitched planes. The transition detail between the two is the part that has to be right.
Arizona hail can dent a panel the same way it dents a car. Denting is cosmetic; the roof still sheds water. Heavier-gauge panel resists it better.
