Consider the exposure
Coastal salt air, snow, wind, and roof pitch inform material and system selection.
PRIME STATE ROOFING · NEW ENGLAND
Distinctive lines.
Lasting protection.
Explore standing seam and exposed-fastener metal roofing for homes, commercial properties, and outbuildings. Understand the profiles, finishes, maintenance, and warranty choices before you decide.
ARCHITECTURAL METAL ROOFING
Good design goes
beyond the surface.
A metal roof brings a distinctive architectural finish to your property. Long-term performance comes from the whole assembly: panel profile, substrate, clips or fasteners, underlayment, flashing, ventilation, and details that allow thermal movement.
Choose the right profile
Concealed fasteners create clean standing seam lines; exposed-fastener panels offer a different budget and maintenance balance.
Plan for the years ahead
Compare coating, panel, and weathertightness warranties separately, with maintenance expectations in writing.
FIND YOUR PROFILE
Three systems.
Three different priorities.
01 / DOUBLE LOCK
Standing seam, mechanically seamed.
A double-fold seam and concealed fasteners offer a system to consider for demanding exposures. The specified clips accommodate panel movement.
- Consider for coastal properties, snow exposure, architectural projects, and eligible low-slope applications.
- Low-slope suitability is profile-specific. Minimum slope, sealants, panel lengths, and details must meet the selected manufacturer’s instructions.
- A premium option with careful attention to seam formation, fastening, and transitions.
02 / SINGLE LOCK
A clean architectural finish.
Single-lock standing seam uses a concealed-fastener appearance with a different seam configuration. It can be a candidate for homes and other appropriately pitched roofs.
- Review the manufacturer’s minimum slope and exposure limits for the exact panel.
- Our brochure uses 3:12 and steeper as a planning reference; this is not a universal specification.
- Compare installed cost, seam details, and available weathertightness coverage.
03 / EXPOSED FASTENER
A practical budget option.
Panels fasten through the face to the supporting structure. Visible screws and sealing washers create a different appearance and maintenance responsibility.
- Consider for barns, garages, workshops, outbuildings, agricultural properties, and light commercial buildings.
- Fasteners and washers need periodic inspection and service. Follow the manufacturer’s schedule rather than waiting for a leak.
- Often the most affordable metal option. Do not assume paint or panel warranties also cover leaks.

| Maintenance | Routine inspection of seams, flashing, drainage, and accessories | Routine inspection of seams, flashing, drainage, and accessories | Routine inspections plus fastener and washer service as required |

*Lifespan and cost comparisons are indicative ranges from the brochure, not a performance guarantee. A metal roof still needs inspection and maintenance. We confirm the actual profile, slope, wind-uplift requirements, coating, and warranty for your project.
The brochure includes general wind-speed and low-slope examples. These do not replace a tested assembly or project design. Your proposal should identify the specific panel system and the requirements for your location.
WHAT YOUR WARRANTY PROTECTS
The finish. The panel.
The installed roof.
These are separate types of coverage. Compare each one, along with its exclusions and maintenance requirements, before selecting a system.
COMPARE THE OPTIONS · SCROLL SIDEWAYS ON SMALL SCREENS
| Coverage | Brochure planning range | What it addresses |
|---|---|---|
| Paint & finish | Typically 30–45 years; some profile comparisons list 30–50 years | Defined coating performance such as fading and chalking. The exact finish, color, substrate, and exposure affect the terms. |
| Panel & substrate | 50 years to limited lifetime in the brochure | Defined failures of the underlying panel, such as covered perforation or corrosion. Coastal and other exclusions may apply. |
| Weathertightness | 20–30 years in the brochure for eligible standing seam systems | Specified leak protection for the installed assembly, subject to inspection, approval, exclusions, and the selected program. |
| Exposed-fastener coverage | 25–40-year paint and limited-lifetime panel examples in the brochure | Product coverage varies. Confirm whether any separate leak coverage is available; do not assume it is included. |
| Prime State Roofing workmanship | Defined in your written agreement | Installation responsibilities, including flashing, seams, underlayment, ventilation, and other specified details. |
Choose the coating deliberately.
Our brochure recommends considering a PVDF finish, including Kynar 500 or Hylar 5000 coating systems, for architectural metal. Compare color retention, chalk resistance, exposure restrictions, and the exact written finish warranty.
Compare alternatives in context.
SMP and polyester finishes may suit different budgets and applications. The brochure lists 15–25-year examples for these coatings; current product warranties and performance vary. We explain the selected finish with your proposal.
Steel, aluminum, and coated substrates such as Galvalume have different exposure and corrosion considerations. No generic “lifetime” label means every condition is covered. Request the actual manufacturer documents before final selection.
For an example of how eligibility and minimum slopes vary by panel, see manufacturer weathertightness guidance. This educational reference does not indicate a Prime State Roofing dealer affiliation.
A CLEAR PROCESS
From the first visit.
Through the final walkthrough.
One coordinated scope for assessment, tear-off, deck repairs, insulation, roofing, and sheet-metal details. Our brochure describes installation by Prime State Roofing’s own crews, with building access and site protection planned in advance.
Assess the roof
We document the roof with photographs and assess the deck, insulation, drainage, flashings, and penetrations. Drone and interior inspections can help build a fuller picture of the conditions.
Put the scope in writing
Your proposal outlines tear-off, deck repair allowances, insulation, membrane or panels, flashing, and disposal. Warranty options are explained and priced separately.
Select the complete system
Compare manufacturers, membrane types or panel profiles, colors, gauges, and coatings, with a clear explanation of how each choice affects performance and coverage.
Plan around your property
Agree on scheduling, access, staging, and dumpster placement. For occupied buildings, plan the work around tenants and daily operations.
Install with attention to detail
Installation follows the selected manufacturer’s specifications. Crews address curbs, equipment, HVAC penetrations, and roof transitions, with daily cleanup and magnetic sweeps where appropriate.
Close out with documentation
A final walkthrough, manufacturer inspection when required, photographs, product information, and registered warranties where applicable complete your project records.

COMMON QUESTIONS
Before you choose a metal roof.
Is standing seam maintenance-free?
No. Concealed fasteners reduce exposed penetrations, but drainage, flashing, seams, coatings, and roof accessories still need routine inspection and maintenance.
Can metal roofing be used on a low-slope roof?
Some specifically engineered profiles are eligible for low slopes. The minimum slope depends on the panel and assembly; seam style alone does not establish suitability.
Will a paint warranty cover a leak?
Usually a paint warranty addresses defined finish performance. Leak coverage is a separate question involving the system’s weathertightness warranty and any installation coverage.
How do I choose between steel and aluminum?
We review the location, salt exposure, roof design, finish, structural requirements, budget, and manufacturer limitations before specifying the panel material.
Can I finance the project?
You can explore the financing page and speak with our financing contact about eligibility, current rates, and available terms. Financing is subject to lender approval.
