Metal Roofing Is Great for Spokane Area Climate

Choosing the right roofing material is crucial for homeowners in Spokane, given the unique climate conditions of the area. Metal roofing emerges as an exceptional choice for several compelling reasons.

First and foremost, its durability stands up to the varied Spokane weather, from heavy snowfall in winter to the hot, dry summers. Metal roofs are known for their ability to shed snow and ice quickly, preventing buildup and potential damage.

Metal roofing offers superior energy efficiency. Reflecting solar radiant heat rather than absorbing it, metal roofs can significantly reduce cooling costs during the warm months. This is particularly beneficial in Spokane, where summer temperatures can soar, making energy efficiency a priority for many homeowners.

Another advantage is the longevity of metal roofing. With a lifespan of 40 to 70 years, it far outlasts traditional roofing materials like asphalt shingles, which often require replacement every 15 to 20 years. This makes metal roofing a cost-effective solution in the long term, despite the higher initial investment.

Metal roofing is highly resistant to fire, wind, and impact, providing an extra layer of safety for homes in areas prone to wildfires, strong winds, and storm-related debris. This resilience is especially valuable in Spokane’s diverse climate, offering homeowners peace of mind regardless of the season.

History of Metal Roofing

A timeline of metal roofing evolution, from ancient to modern techniques, showcased with various metal roof styles and applications

Metal roofing has a long and fascinating history. The first recorded use of metal roofing dates back to the third century BCE when copper roof shingles were installed atop the Lovamahapaya Temple in Sri Lanka.

The Romans also used copper as roof covering for the Pantheon in 27 BCE. Centuries later, copper and its alloys were integral in European medieval architecture.

During the American Revolutionary War, sheet metal roofing was developed by Robert Morris for use in his mansion in Philadelphia. It grew in popularity after being used to replace the roof of Princeton’s Nassau Hall in 1802. In the 19th century, sheet metal roofing became the first metal to be made in American rolling facilities.
