You might think a tin roof isn’t very stable or doable. However, when people talk about a tin roof, it rarely means a roof that is made entirely from tin. Like a steel roof, a tin roof is usually made up of multiple types of metals and coated with an extra layer of protective material to ensure the roof will last for an extended period of time.
Although not very common in Vancouver’s rainforest climate, there are some reasons you might consider them. We’ve given you a list of pros and cons so you can decide for yourself.
A Longer Roof Life
Metal roofing will last as long as your home since it’s very durable and it also resists to all kinds of weather, including high winds which we occasionally get here in Vancouver. Tests have shown that these roofs can last up to 60 years or more and most manufacturers often offer up to 50 years of warranty.
For comparison, an asphalt shingle roof needs replacement within 20 years while a tile roof will give you at least 80 years so tin roofs last somewhere in the middle.
If you compare it with regular tile or asphalt roofing, metal roofing is a lot less heavy. This means some of the necessary roof support given to other types of roofs may not be necessary, which can be a major bonus, depending on how your home is built.
Having a lightweight roof reduces the chance of it collapsing if under some sort of pressure, say a snowstorm or a fallen tree.
Tin roofing is generally easy to install and an experienced roofing contractor can get the job done a lot faster than say a cedar shake roof or a tile roof. This means you can cut the installation time, easing the disruption to your home life, not to mention that you also get to save on the engineering and supporting structure costs.
Tin roofs are better at keeping sunshine out of the house while keeping heat in. This means tin roofs are great for retaining heat into your home which is great, especially in the damp, rainy winters.
While all metal roofs are extremely well suited to resisting the elements, and most can keep your house from getting too warm while it is under the hot sun, some materials are better suited than others. A traditional coated tin roof provides a home with heat resistance that is comparable to the most expensive materials that are currently on the market. While Vancouver isn’t known for it’s heat, it can come in useful in July and August.
If you coat your tin roof with terne, you can actually do a better job of reducing the midday peak temperature of a house in the summer than a regular steel roof, due to the improvements made in the coating itself.
Metal roofing is one of the few roofing materials that are truly fire resistant. Asphalt Unlike other types of roofing, tin roofs are very resistant to fire which makes them safer. Every year homeowners in Vancouver lose their home and possessions due to fire. In fact, there are countless stories of house fires igniting the homes of their neighbors, again due to wind-blown embers. In northern B.C. entire neighborhoods have been destroyed because of forest fire. Homes with wooden tiles, unfortunately give fire the idea conditions to burn.
Shingles and wood shakes may be engineered or treated to be somewhat fire resistant when first installed, but as these roofs dry out and age, they become more and more vulnerable. It only takes one ember from a nearby wildfire, house fire, or even a tree struck by lightning, and the roof is ignited.
A metal roof is green in more ways than one. Manufacturers can make metal roofs with up to 95% recycled material, and if you do ever replace your roof, they are entirely recyclable. Installing a metal roof comes with plenty of indirect ecological benefits, too.
Maximum Snow Shedding
One thing to note here is that metal roofing will make it very easy for snow and rain to run off. This basically means you won’t have to deal with massive snow accumulations or gutter problems, something that can be a major problem with other roof types.
Tin roofs can unfortunately be expensive to build. While there are many factors that go into installing a tin roof, average price is between $14,000 and $16,000. By comparison, an asphalt shingle roof is around $8,000 to $11,000 so there is a significant difference you want to consider.
However, when you put it into perspective to other metal roofs like copper or aluminium, a tin roof coated with terne is among the most affordable types of metal roofs on the market.
For a tin roof to get the maximum lifespan, it is important to make sure the roof is well looked after over its entire lifespan. While some metal roofs require little to no maintenance, such as a copper roof, a tin roof will need to be painted regularly to ensure it doesn’t succumb to weather and heat damage prematurely. Before you decide on this type of roof, be sure to take the additional cost of regular maintenance into account.
In the end, getting a good metal roof can help you improve the appeal and safety of your home. If you can afford to spend a little extra money up front, tin roofing offers some extraordinary benefits and you should definitely consider giving it a try right away. The roofing materials are solid and overall the quality is very good.
