Owner
- Metal roofs last 40 years or more with care, the longest of the four systems we install.
- Retrofit framing turns a ponding flat roof into a pitched metal roof, once the structure checks out.
Standing Seam And Ribbed Panels
Flagstaff Commercial Metal Roofing Contractor
We install, replace, and repair metal roofs on Flagstaff retail, office, and shop buildings. As a commercial metal roofing contractor, we plan snow guards and panel fastening for heavy snow.

Is It A Fit
Is This Roof A Fit For Metal?
Metal is at its best on pitched roofs that need to shed snow. Some low-slope buildings qualify through a retrofit.
Good Fit
- Pitched sections over retail, offices, and shops
- Hotels and lodging with pitched wings
- Flat roofs that need slope, after a structural check
- Buildings where wind resistance matters at the edges
- Owners planning for a long service life
Better Served By Another System
- Low-slope roofs with no structural room for framing
- Eaves over entrances with no room for snow guards
- Small roofs crowded with pipes and vents
- Quiet spaces below where rain noise matters and insulation is thin
Leak Signs
Metal Roof Problems Seen From Inside
Metal roofs give early warnings indoors and on the ground. Each one leads back to fasteners, laps, or snow.
Inside
Drips Along A Straight Line
Drips follow a straight line across the ceiling, matching a panel lap or purlin.
On the roof
Loose Or Backed-Out Screws
Freeze-thaw and panel movement back screws out and crack the washers. We replace them with oversized fasteners and new washers.
Inside
Water On Dry Mornings
Wet insulation or drips appear on cold mornings under clear skies.
On the roof
Condensation Under The Panels
Warm, moist air meets the cold underside of the panels. Better vapor control and insulation below the roof stop this drip.
Inside
Damage Below The Eave
Bent gutters, dented railings, or damaged cars show up below the roof edge after a snow slide.
On the roof
Sliding Snow Slabs
Snow on smooth panels lets go in one slab. Snow guards set in rows hold it on the roof over doors, walks, and parking.
Inside
Rust Streaks On The Wall
Orange streaks run down the wall below a roof edge or gutter.
On the roof
Corrosion At Cut Edges
Exposed panel ends and cut edges rust first. We treat or replace damaged panel ends and reseal the trim.
Inside
Rattling In High Wind
Occupants hear panels or trim rattling overhead during storms.
On the roof
Loose Trim And Ridge Caps
Wind works at loose trim, closures, and ridge caps. New closures and refastened trim quiet the roof and keep blowing snow out.
Your Options
Metal Roof Options For Flagstaff Buildings
Metal work ranges from new screws on an older roof to new panels over a flat one.
| Option | What it involves | When it fits |
|---|---|---|
| Fastener and trim repair | New fasteners and washers, resealed laps, refastened trim | Panels are solid and leaks come from screws and laps |
| Standing-seam replacement | New panels with hidden clips and raised seams | Pitched roofs where the old panels are rusted or damaged |
| Ribbed panel replacement | New through-fastened ribbed panels | Shops and simple buildings on a tighter budget |
| Retrofit over a flat roof | Framing builds slope over the old low-slope roof, then new panels go on | The structure passes a check for the added weight |
| Snow guard retrofit | Rows of guards added over entries, walks, and parking | Solid panels where sliding snow causes damage below |
Who Gains
Why Choose Metal In Flagstaff
Metal pays off on pitched roofs here when the snow and the fasteners are planned for from the start. Here is who gains.
Facility Manager
- Hidden clips on standing-seam panels leave far fewer exposed screws and washers to check every spring and fall.
- Smooth panels let snow slide off pitched sections instead of loading the roof all winter.
Tenants And Staff
- Snow guard rows keep slides off doors, walks, and parking, and let the snow melt in place on the roof.
- Interlocking seams and fastened clips resist uplift at the edges and corners during summer storms.
Roof Trouble
Snow Sliding Onto The Entrance?
Call and tell us where the slides land and what the roof panels look like. Snow guard placement starts from that.
How The Work Runs
How We Install Metal Roofs Around Flagstaff
Metal jobs depend on the structure as much as the panels, so the order starts with what sits under them.
Inspect Your Roof
We check fasteners, washers, laps, trim, and panel ends, and look for condensation inside. For a retrofit, the framing and structure get checked for added weight.
Lay Out Panels And Snow Guards
Panel runs, clip spacing, and snow guard rows are set for the slope and for what sits below each eave of the roof.
Install Panels In Sections
Old panels or roofing come off one section at a time, ice-barrier underlayment goes down at the eaves, and new panels are seamed or fastened.
Trim, Guard, And Walk It
Ridge caps, closures, and edge trim are fastened, and snow guards are attached. We walk the finished roof with you, eave by eave.
Roof Systems
Systems That Pair With Metal
Many Flagstaff buildings combine a metal roof with a membrane on their flat sections.
Industrial Roofing
Plants and warehouses with flat main roofs and pitched wings often combine an industrial membrane with metal sections.
EPDM Roofing
Flat areas next to metal that are crowded with pipes and vents often take EPDM, which stays flexible through hard freezes.
Common Questions
Metal Roof Questions
What owners ask about metal roofs, snow, and fasteners in Flagstaff.
Why choose a metal roof for a commercial building in Flagstaff?
Metal sheds snow well on sloped roofs, resists wind, and lasts for decades with care. Standing-seam panels are common on retail, offices, shops, and newer buildings with pitched sections.
Sliding snow is the main design concern. Snow guards, careful eave placement over entrances and walkways, and secure fastening at the panel ends keep slides from damaging gutters, vehicles, or people. Retrofit metal over a low-slope roof also works on some buildings after a structural check.
How often should metal roof fasteners be checked?
Every spring and fall on through-fastened ribbed roofs.
Freeze-thaw cycles and panel movement back screws out and age the washers, so we look for loose heads, cracked washers, and rust rings around each screw, and replace the ones that have let go.
Where should snow guards go on a metal roof?
Over every door, walkway, parking row, and lower roof that sliding snow could hit.
Guards are set in rows sized for the slope and panel length, and fastened to the seams or through to the structure so the load of a full slab stays on the roof.
Is a metal roof loud in storms?
Panels over open framing can be.
Insulation and a solid substrate under the panels quiet rain and hail noise, which matters over offices, classrooms, and guest rooms, so we plan that layer during the inspection.
Can old metal panels be fixed instead of replaced?
Often, yes. Replacing fasteners, resealing laps, and treating rust at cut edges extends a roof whose panels are still solid.
Rust-through, widespread holes, or panels bent by snow slides point to replacement of those runs or the whole roof.
What causes condensation drips under a metal roof?
Warm, moist indoor air reaching the cold underside of the panels.
The fix is insulation and vapor control below the panels, so we check for condensation before chasing a leak that turns out to be indoor moisture.
Do metal roofs need an ice barrier at the eaves?
On sloped sections, yes. Ice-barrier underlayment at the eaves keeps water that backs up behind ice from reaching the deck.
It goes down along every eave before the new panels during a replacement.
