Why Fire-Resistant Roofing Matters
If you live in an area prone to wildfires, you understand the importance of choosing materials to protect your home. The roof is one of the most vulnerable parts of any house during a fire. Near-fire embers can travel miles, landing on rooftops and igniting flammable materials. Choosing a fire-resistant roofing system isn’t just a precaution—it’s a necessity.
The Power of Class A Fire-Rated Roofing
Interlock® Metal Roofing Systems are engineered with fire safety in mind — delivering high-performance protection for homes in wildfire-prone and rural areas. Our non-combustible aluminum shingles are designed to resist ignition from embers, sparks, and direct flame exposure, offering critical defense where structural fire risk is elevated.
When installed with two layers of GAF VersaShield® underlayment over a 15/32” plywood deck, Interlock Metal Roofing Systems can achieve a Class A fire rating — the highest standard for residential roofing in North America.
Unlike combustible materials such as wood or asphalt, which can accelerate fire spread, an Interlock roof helps slow ignition and buy you precious time — and peace of mind. Built to withstand extreme heat and designed to protect, our roofing system gives your home the fire resistance it deserves.

The Great Fire of 1830 and Interlock Metal Roofing: Past Lessons, Present Protection in Gloucester, MA
Although Gloucester purchased its first fire engines in 1793, it was the catastrophic ‘Great Fire of 1830’ that served as a wake-up call to the town’s residents, highlighting the urgent need for improved fire protection measures. On Thursday, September 16, 1830, a house owned and occupied by Mr. Samuel Gilbert on the western end of Front Street (now Main Street) caught fire. The blaze quickly spread, engulfing at least 27 dwelling houses and 43 stores and workshops, most with their contents, from the town landing to Porter Street.
The Samuel Gilbert House, originally built in 1750 by Nathaniel Ellery and later home to the prominent merchant Samuel Gilbert, stands today at the corner of Angle Street and Western Avenue. The historic structure now features Interlock Metal Roofing, a fire-resistant roofing system that exemplifies today’s commitment to fire safety in historic preservation. This modern addition to the historic house serves as a reassuring symbol of our town’s commitment to preserving its architectural heritage while ensuring the safety of its community.

Following the fire, the town’s citizens voted to purchase one of the newer types of engines. This engine, the Hydraylion, was a significant advancement in fire protection. It pumped water from the well or cistern, through a hose, to the hand tub, where the men then pumped the water onto the fire. This new method of firefighting, using a hose line instead of buckets, was a game-changer. The fire also led to the formation of the first Hook, Ladder, and Axe Company. Previously, the ladders had been stored in boxes, which were located in various sections of the town. The early ladder trucks were called fire escapes. Gloucester, MA Chamber of Commerce
The General Court passed a Special Act in 1831 “to establish a Fire Department in the First or Harbor Parish, in the town of Gloucester,” Addison Gilbert Hospital in Gloucester, MA 01930 – 978-283… marking the beginning of organized fire protection that continues to serve the community today through four fire stations and 83 professional firefighters.
