While asphalt shingles have long been the roofing material of choice by Canadian homeowners, metal roofs are now growing in popularity thanks to their higher durability and long-term savings potential. eieihome.com spoke with Max Guerra of New Steel Roofers Inc., a Hamilton-based metal roofing company, to discuss the benefits of metal roofs.
Asphalt shingles rose to popularity thanks to their low cost and availability, but increases in the price of petroleum (what asphalt shingles are made from), meant manufacturers began making the shingles thinner in order to maintain their low prices. This reduced the shelf life of asphalt singles to 8 to 12 years. “Asphalt shingles start deteriorating from the day they go up [as a result of exposure to the elements],” says Guerra. Metal roofs, by contrast, can withstand years of abuse from extreme weather conditions – even winds up to 120 mph – and have a lifespan of 80 to 100 years.
Metal roofs can be installed over existing asphalt and wood shake roofs, causing less disruption to homeowners by eliminating tear-off time and disposal mess.
While the word ‘metal’ may conjure images of rusty, faded barn roofs; metal roofing has undergone a number of changes in the last decade. New colours and coatings are now available, but Guerra says one of the greatest changes has been a new stone-coated slate metal roof which New Steel Roofing Inc. began supplying only six months ago. “Your typical metal roof, you can spot them right away [but] stone-coated metal looks natural. You don’t get that shiny paint look,” says Guerra. Stone-coated metal has other advantages beyond style. While snow and ice build-up on a typical metal roof results in an avalanche effect as it falls off all at once, stone-coated metal allows snow and ice to melt off naturally, eliminating slide off. Stone-coated slate metal also eliminates noise from a typical metal roof. “It won’t ping when it rains,” says Guerra.
Increase a home’s resale value
A metal roof comes with a lifetime warranty for the original homeowner and a 50 year transferrable warranty. “It’s a great selling feature when you’re selling your house to have a roof with a 50 year warranty [for the new homeowner],” says Guerra.
