Rolls of steel used for metal roofing

Galvanized Metal Roofing

Up to 30% more steel for added strength

When you invest in distinctive metal, you’ll appreciate knowing we selected the highest quality for long-term performance. ProVia’s metal roofing is constructed of highly durable 26-gauge steel, providing up to 30% more galvanized steel than the industry average, while also being 3x lighter than asphalt shingles. This commitment to a heavier-gauge galvanized steel provides added strength and lifetime protection from wind, rain, hail and corrosion.

4-point locking system

Weather-resistant design

ProVia’s metal roofing system was designed and constructed for serious weather resistance. The 4-Point Locking System includes a top lock, under and over locks on the sides, and our exclusive WaveLock™ ribbed feature on the bottom that increases the rigidity and strength of the panel. Recessed water stops, water damming features, and shedding channels funnel water away, so sheeting rain cannot penetrate. 

The system provides edge-to-edge secure panel placement and field anchoring for certified protection against wind uplift speeds up to 180 mph.

This residential metal roofing system has been independently tested and approved for:

  • High-Velocity Hurricane Zones (HVHZ) within Florida, including Miami-Dade and Broward Counties
  • Application in and outside of Florida’s designated wind-borne debris areas
  • Design pressures that are equal or less than -56psf.

Our metal panel roofing system meets the following Florida testing requirements for certification in HVHZ and non-HVHZ areas:

  • TAS 100 Wind and wind-driven rain resistance
  • TAS 110 Physical properties of roof membranes, insulation, adhesives, mastics and coatings
  • TAS 125 Uplift resistance testing for roofing panels.

State-of-the-Art Steel Embossing

Texture you can see and feel

Our slate and shake roofing panels look and feel like natural slate and cedar shakes because we hand selected varying pieces of these natural products as models for our roofing. The variegated texture of the shake and slate panels is made up of tens of thousands of surface impressions that mimic the natural look and feel of classic slate and shake shingles. A state-of-the-art steel-embossing process creates the textured details, adding strength to its form, while realistic hues accentuate the authentic look of hand-split wood shake or quarried slate.

Galvatec Finish System

Unsurpassed protection & beauty

ProVia’s exclusive GalvaTec™ finish system raises the benchmark for true-to-life aesthetics and the enduring performance demanded by today’s most discerning consumer. The hardened, resin-based surface of this finish system protects the metal slate and shake shingle roofing from unsightly algae formation and black streaks that are prevalent in granular and porous roofing materials, like traditional asphalt, slate and wood shakes.

This premium architectural coating meets or exceeds ASTM performance standards for UV protection against chalking and weathering, offering long-lasting beauty and durability as long as you own your home.

Lasting Solar Defense

For energy savings

The GalvaTec finishing process also provides a highly reflective and highly emissive factory-coated finish, which keeps the roof metal cool during warmer months, thereby reducing energy consumption, enabling lower air conditioning costs, and improving indoor comfort.

Finishing Trims & Flashings

Anchoring performance & refinement

Sometimes, what you can’t see is what’s most important. The essential role of unexposed roof flashing is to protect against water infiltration and consequential damage. In simultaneous defense, roof trim components are precisely formed to anchor the overall system together and prevent uplift. Components, especially exposed rake and valley trims, provide the final edge-to-edge fit-and-finish for a refined appearance.

Environmentally friendly steel

Recycled and recyclable

Our slate and shake metal roofing panels are American-made with recycled steel and are 100% recyclable at the end of their lifespan, making ProVia’s metal roofing one of the most environmentally sound roofing materials you can buy.

Standards & Certification

Independently tested

ProVia’s metal roofing products are voluntarily third-party tested and certified, and meet or exceed stringent industry standards.
  • CRRC Rated Product—The CRRC was created in 1998 to develop accurate and credible methods for evaluating and labeling the solar reflectance and thermal emittance (radiative properties) for roofing products, to support research, and serve as an educational resource for information on roofing. Each of ProVia’s metal roofing panel colors have been rated for solar reflectance, and these values are listed by the Cool Roof Rating Council (CRRC) at
  • ENERGY STAR®—ProVia’s metal roofing products are pending completion of a 3-year certification evaluation for initial and aged solar reflectance values.
  • Metal Roofing Alliance—ProVia is a proud member of the Metal Roofing Alliance (MRA), which is the leading voice for companies and professionals involved in the residential metal roofing industry. The MRA is dedicated to helping homeowners make educated roofing decisions and connecting them with expert metal roofing professionals.
