Asphalt Shingles

The price is by far the greatest advantage of composition asphalt shingles. This is one of the most affordable roofing options in the short term, which is why so many homeowners favor it. Asphalt shingles provide adequate protection from the elements for 8 to 12 years, at a relatively low upfront cost.


Disadvantages of asphalt shingles

“You get what you pay for” is a tried and true saying in the roofing industry. For their low prices, asphalt shingles have a considerable number of disadvantages that must be taken into consideration when purchasing a new roof. These are some of the common issues that are associated with asphalt shingles:
– Cold weather compromises the integrity of asphalt shingles; they may crack if installed in cold temperatures.
– Asphalt shingles can be damaged by ventilation issues in the attic.
– Wind uplift is a prominent issue with asphalt shingles, especially those of poor quality.
– Expansion and contraction of the roof due to temperature fluctuations can cause extensive cracking of asphalt shingles.
– Extreme heat can cause shingles to crack and loose colour, they can only perform in moderate temperatures and climates.
– Regular maintenance and repairs are required and are better done before it rains or snows to prevent further damage to the shingles.
– Asphalt shingles have a very limited lifespan, they start deteriorating, losing granules and becoming more brittle, as soon as they are exposed to the elements.
– By and large, asphalt shingles do not get recycled and end up in the landfill as construction waste. They are a petroleum based product and they require a great deal of energy to produce. Given their relatively short lifespan, it is clear that asphalt shingles are not a very environmentally friendly product.

Ask Mike Holmes: What Roofing Material is Best?

Here’s the second in our series of fan questions for Mike Holmes, host of Holmes Makes it Right and our go-to for everything reno related.

Our Facebook fan Janet C asked, “We live just north of Toronto. We'll need to replace our roof in a couple of years. Is it worth the cost to get a steel roof versus asphalt shingles? We plan on living here until we retire - about 25 years.”

Mike Holmes replied, “I love metal roofs. It’s one of my favourite roofing materials (I also love a flat green roof). But I like metal for a few reasons. One, it lasts. A metal roof is one of the most durable roofs you can have. It can last up to 50 years. Two, it’s resistant. It resists insects, mildew, rot, UV rays—not to mention fire-resistant. And it won’t crack or curl like asphalt.

If you go with asphalt, you’ll need to replace your shingles at least twice. I don’t care what the warranty says: An asphalt shingle will last 10-15 years—maximum. They start to break down as soon as they’re exposed to weather. And if you don’t replace them you expose your home to the elements, making it vulnerable.

If you’re staying put—and it sounds like you are—you want a metal roof. Is it more expensive? Yes. It can cost more than twice as much as asphalt. But it’s an investment. You save money in the long run because you won’t need to replace it—and you protect your home. A metal roof can last 3 times longer, raise the value of your home and reduce maintenance. All pluses.”
