Steel roofing versus asphalt shingles

Asphalt shingles generally cost less than metal, and the rough surface of asphalt shingles prevents snow slides.

Metal roofs can lead to large and sudden snow slides and the surface can be noisy during heavy rainfalls.

Metal roofs are quick to install, they keep rain out for many decades, and the material can be recycled when the roof is no good.

Made with petroleum-based ingredients, asphalt shingles aren’t as green a building material as roofing metal because shingles cannot be economically recycled.

Construction and renovations

Do-it-yourself (DIY) packages are available for commercial construction projects and home renovation projects.

Top brand names include Nailite, Weathershield Insulation, Royal Building Products, Metro Roofing, Quality Stone and James Hardie.
