Metal Roofing for The Ottawa Region
Metal roofing in Ottawa has a long history that started on Parliament Hill. Believed to be the first of it’s kind in North America, the original wrought-iron roof of the Parliamentary Library was imported from Manchester in around 1869. After progressive restorations throughout the 19th century, all of the original Parliament buildings are now adorned with copper roofs. Although beautiful and extremely long lasting, copper roofing, because of its hefty price tag, is not accessible to most Canadians. Homeowners in Ottawa wanting a durable and long lasting alternative to common asphalt shingles have the option of steel or aluminum roofs.
How Do I Chose the Right Metal Roof for For My Home?
As Metal Roofing gains popularity in The Ottawa Region, product options are growing. Homeowners wanting a truly permanent solution can get the best ROI by understanding what to look for.
Metal Roof Benefits
Residential Metal Roofing Options
In Ottawa you will find a decent range of metal roofing product options. Questions to ask yourself before trying to identify the right product are:
How long will I be living in this home?
This is an important question because you can compare cost over time for any product that you are considering. Pro Tip: try to use your own experience rather than warranty claims about how long an asphalt roofs last. Asphalt warranties are heavily pro-rated and 90% of re-roofing inquiries we see here are at year 11-12.
Is a maintenance-free product important to me?
Through fastened metal roofs that need to be installed over battens are not maintenance-free. At some point you will need to tighten and/or replace the screws and repaint exposed steel that has rusted. Systems with concealed fasteners cost more but eliminate the need to tighten and replace screws. Aluminum systems also cost more but will never rust. People on a fixed income or with mobility issues will be further ahead to pay more up front for a maintenance free option.
How much do I care about cosmetic lifespan?
Steel roofs that can functionally last 40 to 50 years will typically lose their visual appeal in a much shorter time-frame. While an old steel roof may keep your home watertight for the duration of its warranty, its appearance could diminish the resale value of your home. Currently PVDF coatings will give the longest cosmetic lifespan but won’t prevent rust on exposed edges (unavoidable for installation). Aluminum roofing with PVDF coatings cost a bit more but offer the longest cosmetic life for a metal roofing product.
