Read comparison scope and maintenance notes
Same project, same scope. Summit’s displayed rate is an installation planning base, not a complete replacement quote. Tear-off, disposal, decking repairs, engineering, freight and travel are quoted separately. The 29-gauge rate is local pricing reported by Summit, not an independent market survey or guaranteed quote. Other alternatives need a local project quote. Lifespans are general reference figures, not promised replacement dates. Salt exposure, weather, pitch, ventilation, workmanship and maintenance affect actual performance.
Exposed-fastener maintenance costs
Lower upfront cost brings added maintenance exposure. Plan for exposed screw replacement around 20 years, with regular inspections and earlier repairs when needed. Failed washers, loose screws and enlarged holes can allow water into the building. Re-screw work adds labor and access costs beyond the original installation price. Summit’s concealed panel attachment reduces these exposed washer-dependent seals; its 24-gauge steel and PVDF finish also address rigidity and finish aging. These are separate performance advantages, not equivalent roof specifications.

Siding cost & care
Compare the purchase price.
Then compare the upkeep.
Summit’s standard 24-gauge AZ50/PVDF steel siding starts at $17.99 per square foot of gross wall area, plus opening details. Our custom flashed BB750 package uses a $28 per gross square foot planning rate including wind-cleat bands and wider window and door trims on prepared walls up to 10 ft high. Vinyl often costs less upfront; fiber cement and cedar bring different finish-maintenance needs. Compare matching project scopes before choosing.

Read lifespan together with upkeep. These are published general material benchmarks, not matching field studies or Cordova/Valdez forecasts. Installation, salt exposure, drainage, damage and maintenance affect actual life. Finish appearance, sealants and fasteners can need attention before the siding needs replacement. The steel figure describes another manufacturer’s system; it is a reference, not a tested Summit service-life claim.
Siding price scope and comparison inputs
Vinyl, fiber-cement and cedar prices are national installed-cost references. Summit pricing uses gross wall area without deducting openings. The $28 custom BB750 package includes wind-cleat bands and wider window / entry-door trims on prepared walls up to 10 ft. Height allowances are additional. Garage or oversized openings, exceptional trim layouts, demolition, sheathing, weather barrier, wall straightening, soffit, freight and travel are quoted separately.
Summit’s PVDF steel combines a durable factory finish with heavier metal and custom flashing. Regular washing and inspection replace the recurring stain work associated with finished cedar.

Made in Alaska certified
Local manufacturing.
One complete exterior.
We manufacture the panels and install the finished system. Our portable equipment makes panels right at your job site, cut to the lengths your project needs. Roofing, siding, soffit and custom flashing come together through one company. Our owner has installed steel since 2004. Since 2010, that experience has included metal roofing and siding on military projects at Fort Greely and Fort Wainwright, communities across rural Alaska, and siding and dormitory roofing at Prince William Sound College.
Our minimum steel specification is 24 gauge with an AZ50 aluminum-zinc coating and a PVDF paint finish. Panel choice, fasteners, substrate and flashing details are selected for the actual project.
Roofing
Concealed-fastener standing seam with notched and hemmed eave and valley options, captured gable edges and ridge caps attached to Z closures.
Siding & soffit
Board-and-batten siding, solid or perforated FWQ100 soffit and optional under-deck panels for a coordinated exterior. Siding is priced separately and can cost more per square foot than a simple roof.
Custom flashing
We fabricate corners, transitions, wind-cleat bands and wider window and door trims to complete the exterior as one coordinated system.
Why choose Summit?
Heavier steel.
Reinforced edges.
Fewer exposed screws.
We build with 24-gauge AZ50/PVDF steel, concealed panel attachment and custom flashing. Our hemmed option folds the raw cut underneath, reinforces the edge and captures the eave without exposed panel-face screws.
24-gauge AZ50 steel
Heavy steel with an aluminum-zinc corrosion barrier, manufactured into Summit’s roof and wall profiles.
Four-layer eave reinforcement
Our panel hem, cleat and doubled T-style drip reinforce the overlapping edge. Four equal-size 24-gauge layers can provide about 8.3× the calculated bending stiffness of one 26-gauge layer when all four layers contribute equally. See the calculation below.
Concealed panel attachment
Captured eaves and gables and ridge Z closures reduce exposed screws through the panels.
Folded steel and a sheltered cut
Notching allows the panel end to fold into a hem. At our described eave connection, four overlapping 24-gauge layers engage the cleat and doubled T-style drip. The hand-seamed connection reinforces the edge and shelters the raw cut while retaining sliding clearance for thermal movement.
Did you know? Four layers add substantial bending stiffness.
About 8.3× the calculated bending stiffness compared with a single 26-gauge flat strip of equal width and the same 1-inch unsupported overhang.
Using 0.023-inch 24-gauge steel and 0.018-inch 26-gauge steel: 4 × (0.023 ÷ 0.018)³ = 8.35.
How this eave comparison is calculated
This is an idealized elastic-bending calculation for four equal-width flat layers with the same 1-inch bending length, elastic modulus and support conditions. It adds the stiffness of four independent layers, assuming each engages equally. Under that model, deflection is about 88% lower under the same total load. The four layers are not assumed to be a bonded solid plate.
Our folded eave has different shapes and load paths. Layer engagement, slip, cleat attachment and support affect its actual response. This calculation illustrates the material advantage; it is not a tested eave rating, tear-strength rating or wind-uplift capacity. Calculation basis: MIT beam-bending theory.
Capture the edge and attach the cap to Z
Our commercial gable/J combination captures the panel edge without exposed screws through it. Ridge caps attach to Z closures rather than directly through panel ribs. These details reduce exposed panel penetrations and washer-dependent weather seals.
Did you know?
Equal size. More steel. Greater resistance to bending.
For equal-width, equal-length flat steel samples of the same grade, a 0.023-inch 24-gauge sample has about 2.09× the bending stiffness of a 0.018-inch 26-gauge sample and 4.25× that of a 0.0142-inch 29-gauge sample. Under the same small load, that means approximately 52% and 76% less deflection, respectively.
Compare deflection, bending strength and resistance to rupture
Calculated material comparisons, using the same steel properties, width, unsupported length, loading and supports. Thicknesses below are illustrative comparison inputs; gauge labels and supplier tolerances vary. Use certified base-steel thickness for a project-specific calculation.
| Material | Thickness input | Bending stiffness | Deflection under equal load | Bending moment at first yield | Tensile rupture capacity |
|---|---|---|---|---|---|
| 24 gauge — Summit’s specified gauge | 0.023 in | 100% | 100% | 100% | 100% |
| 26 gauge | 0.018 in | 48% | 209% | 61% | 78% |
| 29 gauge example | 0.0142 in | 24% | 425% | 38% | 62% |
What about tearing? At equal tensile strength and equal net width, 24-gauge steel in this example has about 28% more tensile rupture capacity than 26 gauge and 62% more than the 29-gauge example. That describes a strip pulled apart across its net section. Tearing at a screw, clip or fold is a different failure mode; its capacity requires the actual connection geometry, steel properties and applicable design method or testing.
Calculation basis: Flat-strip elastic stiffness scales with thickness cubed; deflection scales inversely with that stiffness. First-yield bending moment scales with thickness squared at equal yield strength. Net-section tensile rupture capacity scales with thickness at equal tensile strength and net width. These ratios do not describe formed-panel snow-load ratings, allowable spans or tested uplift resistance. PVDF finish and AZ50 coating are specified for protection; these strength comparisons concern the steel substrate.

Finish performance and service life
Better color retention.
Fewer exposed screw seals.
PVDF is the premium finish for long-term color retention and resistance to chalking. Sheffield identifies it as the stronger choice for preserving color over decades of exposure. Summit combines that finish with heavier 24-gauge steel, an AZ50 aluminum-zinc coating and carefully formed edge details.
| What changes over time | Summit PVDF | SMP alternative |
|---|---|---|
| Color retention | Stronger resistance to fading, including bright and vivid colors. | Pigments lose color sooner under comparable exposure. |
| Chalking | More durable resin resists chalking over long exposure. | Resin breakdown produces more visible chalk residue. |
| Long-term appearance | Premium finish selected to preserve the exterior’s color longer. | Lower initial finish cost with greater fading and chalking over time. |
Remove the screw seal from the panel face
An exposed-fastener roof relies on a weather seal at every panel screw. Loose fasteners, deteriorated washers and movement around penetrations create ongoing service work and potential water-entry points. Summit’s concealed panel attachment and captured edge details eliminate those exposed screws at the specified panel locations. Maintenance focuses on the roof’s seams, flashing, drainage and sealants.
Published manufacturer guidance
50–60 years or more
McElroy Metal publishes this service-life benchmark for properly installed metal roofing and identifies PVDF as a finish that keeps a long-lasting roof looking good for decades. Summit’s heavier steel, premium finish and reduced exposed panel penetrations address physical damage, finish aging and fastener maintenance together.
