Not sure how he does it, but Mike Holmes takes the most boring sh*t in the world and makes it seem interesting. I wish I would have had more college professors like Mike, would have made chemistry a lot more bearable. In this article, reposted from the Ottawa Citizen, Mike talks about choosing the right kind of shingles for your roof. He cautions people not to get taken by the word "organic" when it comes to asphalt shingles. In this case, the word does not mean "green" or signify a more environmentally friendly choice. Instead, it merely means non-synthetic. In some cases the asphalt singles that contain synthetic materials such as fiberglass are better, depending on the type of roof you have and what kind of climate you live in. Mike also talks about some people who chose the "organic" shingles, only to have them begin to deteriorate after 5-8 years, instead of the guaranteed 30 years they were promised by the manufacturer.
When it comes to roofs, the consumer has many options. All of them have their positives and their negatives (all depending on the type of roof and the climate), so its important to know what you're buying, and how long it's going to last. If Mike had his way, everyone would have a metal roof. Metal roofs are very expensive, but they last about 50 years, as opposed to 30 years for a well-installed shingled roof. They're also recyclable, which is a big plus for Mike. If it's time to replace your roof, read Mike's article about choosing your shingles carefully...
Take care when choosing your shingles
A couple of companies have recently come under fire with this product. What’s the problem? They’re cracking, curling and even being torn off roofs within a few years.
Most shingles come with a 25- to 30-year guarantee. The ones involved in the lawsuit did, too. But many homeowners have had to replace the shingles within eight years — sometimes even as little as five. Who’s to blame?
Homeowners say the product’s no good. Manufacturers claim it’s poor installation. What’s the verdict? In some cases, the jury’s still out. In others, settlements are being reached. But the truth is, settlement or not, homeowners just want a good product and a good roof. The hassle of re-roofing is a headache for everyone.
Booking a good roofing contractor is difficult — the best ones are booked months in advance. If you’ve already gone through the trouble once and have to go through it again within a few years — plus pay additional labour costs — it can make more than a just a couple of homeowners angry.
Are organic shingles organic?
There’s some confusion around organic shingles. Some people think they’re green, environmentally friendly or made from organic material. That’s not the case — it’s just clever marketing. When it comes to shingles, organic means non-synthetic.
Organic shingles are your regular asphalt shingles — the same petroleum-based shingles that have been on the market for decades. The reason why asphalt shingles are now being called organic is because there’s a new kid on the block: fibreglass shingles.
Most organic shingles have a layer of non-synthetic materials underneath the asphalt and granules, usually recycled newspaper and cardboard. Fibreglass shingles have a layer of synthetic material — glass fibre.
Organic and fibreglass shingles look the same. They’re both made from asphalt and granules. They’re installed exactly the same way, too. But the layer of glass fibre makes fibreglass shingles absorb less moisture and be more resistant to heat, which increases their durability in a warm climate.
Fibreglass shingles usually hold up better if a roof has poor ventilation. This can make some homeowners want to choose fibreglass — a kind of Band-Aid solution for a poorly vented roof. But I say fix the ventilation.
Roofs need to vent
Proper ventilation means the temperature difference is minimized between the attic and air outside. This prolongs the life of your roof. It also eliminates moisture that can get trapped inside the attic. If moisture stays there, it can lead to rot and mould.
Building code varies from city to city. But my roofing guys like to keep one square foot of venting for every 300 square feet of roofing.
Different types of shingles
There are plenty of different shingle products out there. Most homeowners choose based on their budget. But like everything else, you get what you pay for.
Compared to other shingle materials, asphalt is inexpensive. That makes them popular. Most roofs have them — about four out of five homes in North America. But they’re not as durable as other types of shingles.
Cedar shingles and cedar shakes are among the most expensive roofing materials you can choose. These are the real “organic” shingles and they can be composted. Why are they expensive? Partly because of the material itself — cedar looks and smells great. But labour and installation costs are also high.
Installation is slow because each cedar shingle is nailed to the roof, usually by hand. It’s also high maintenance. It’s best to keep a wood roof as dry as possible, even if it’s cedar. And you might also need to add a fire deterrent. But keep in mind: Time and weather will reduce its performance.
Some fibreglass shingles come with a 50-year warranty. They’re also more fire-resistant than organic.
Laminated or architectural shingles are thicker, making them more durable than regular asphalt shingles. But if you want top of the line, you want metal.
Metal roofs are my favourite. They’re easy to install, fire-resistant and, in terms of durability, there’s nothing better — they last about 50 years.
What’s the downside? Metal roofs aren’t cheap. But they are definitely worth the investment. They last two to three times longer than asphalt roofs. Plus metal roofs are recyclable. Some are even made from recycled metal. When you consider 10 million tons of asphalt waste ends up in landfills every year, metal roofs are the greener choice.
No matter what type of shingle you choose, quality is key. Always choose a high-quality product. It’s better to have high-quality asphalt shingles than low-quality fibreglass or cedar shingles. And make sure the shingles you choose are installed properly. You can have the best quality shingle. But if it’s installed improperly, it will not last. If you do it right, you do it once.
