Weather Protection

For durable, long-lasting roof or wall cladding systems that will stand up to weather extremes, look no further than metal. Steel and aluminum metal panels come in a variety of profiles and colors to suit any creative vision. They are environmentally friendly, can be made from recycled materials and are 100% recyclable at the end of life, which often is 40 years or more. Metal roofs and walls contribute to earning LEED building credits, utilize durable coatings that endure harsh climates and help reflect the heat of the sun. Additionally, the strength and durability of metal provides excellent resistance to high winds, even at hurricane-level force, and resist damage from flying debris. When properly installed by a professional, interlocking panels provide a watertight seal to prevent damage during heavy rains and hurricanes.

Answers to Questions about Metal Roofing

Is metal roofing energy-efficient?

Yes! Metal roofing has many energy-efficient features:

Reflectivity: High-quality “cool roof” coatings and finishes reflect the sun’s rays, reducing the amount of solar heat absorbed by the roof and its thermal emittance. This keeps buildings cooler and reduces the urban heat island effect, which is particularly beneficial in hot climates.
Longevity: The longer lifespan of a metal roof (compared to other roofing materials) reduces the frequency of replacement, making it more sustainable and cost-effective.
Insulation compatibility: Metal roofs are compatible with a variety of insulation materials. When properly insulated, a metal roof helps prevent heat loss, keeping buildings warmer in winter and reducing heating costs.

How does metal roofing perform in high winds and rain?

Properly installed metal roofing is highly wind-resistant, watertight and able to withstand impact from hail or other debris. No roof is hurricane-proof, however metal roofs provide a great solution in areas with extreme weather conditions. Look for metal roof systems that perform well under testing conditions, including:

Wind uplift resistance testing: The ability of a metal roof to resist uplift caused by high winds. This assesses the structural integrity of the roofing system and its attachment to the roof deck.
Water penetration testing: The ability of the roof to shed water and prevent leaks under simulated rainfall, including wind-driven rain.
Impact resistance testing: The ability of a metal roof system to withstand impact from hail or other debris.
Fire resistance testing: The ability of the metal roof to resist ignition, flame spread and the transmission of heat.
Corrosion resistance testing: The ability of metal roof systems to resist rust and corrosion in harsh environments, such as near saltwater.

Metal roofing systems also can be tested for other performance features such as fire resistance, overall durability, thermal performance, material strength, and adhesion and coating testing. Are metal roofs compatible with solar panels?

Are metal roofs compatible with solar panels?

Yes! Metal roofs are a popular choice for solar panel installations. Here is why they are a good match:

Structural strength: Metal roofs provide a stable, secure platform with a robust structure that provides good support for solar panels.
Long lifespan: A properly maintained metal roof likely will outlast the lifespan of the solar panels, reducing the need for roof replacement during that time.
Ease of installation: Some solar panel mounting systems can be easily and securely attached to metal roofing without compromising the roof’s integrity.
Lightweight construction: Metal roofing is lighter than some other roofing materials, minimizing the stress on the roof structure.

What is the lifespan of a metal roof or wall panel system?

Metal roofing and wall systems are known for their longevity and low maintenance. The overall lifespan depends on a variety of factors including the type of metal used, quality of installation, coating and finish quality, climate conditions and maintenance practices. In general, metal walls and roofs have an expected lifespan of 20-40 years, and possibly even longer depending on location and other factors.
