What’s the best type of roofing to resist hail in Calgary Alberta? Is it EPDM rubber roofing? How about a metal roof? Or a hybrid? Or a slate roof? Or an energy saving white roof? Or a new design? Or a traditional slate roof? You get the picture. for roofing in Calgary
You might think it has to do with “how much hail you get” because it can reduce the intensity of the storm, however that is not entirely true. The best type of roofing to resist hail is one that traps the fine debris so it lands on the ground rather than in your gutters and downspouts.
What if you have an old roof? Will it still hold up the next storm?
The answer is yes it will. But just like your car or RV, the older the roofing calgary , the more maintenance it requires. Consider the life of your roof. For an asphalt roof, it’s 20 years. For a metal roof, 30 years. And for a slate roof, it lasts a lifetime. And in the case of a concrete tile roof, the material is fire resistant and rated to withstand hurricane winds, providing protection for your building for decades to come.
So what’s the worst type of roofing to resist hail?
Well it depends on where you live. In areas where hail is common, the answer is very likely to be EPDM rubber roofing. For example in Arizona your options are limited to EPDM roofing or an organic roof. But if hail is a rare occurrence in your area, you might be able to get away with an EPDM rubber roof.
But if hail hits your concrete tile roof, well your options are limited. The roof can’t be reinforced because the mortar between the tile and the base sheet is just too weak. It’s either reinforce the tile roof or just take the tile off and replace it with a cheap asphalt roof.
But the best option is to install a hail resistant synthetic roof. That is what the majority of builders, contractors and building contractors recommend. In fact, the Canadian National Building Code recommends synthetic rubber roofing, stating that “rubber roofing has superior performance in hail, snow, wind and other hazardous conditions.” That’s because a synthetic rubber roof is constructed of a base of ethylene vinyl acetate, which is then coated with granules made of zinc and aluminum. The result is a durable synthetic roof that’s better able to withstand hail than an organic roof.
You might be saying to yourself, “But Steve, hail only comes up to my house and not yours.” That’s because the rubber roof is often made to fit particular types of roofs. For example, in the event that your home is made of metal, you’d use a flat base that fits over the existing roof, a pre-drilled hole in the roof, etc.
But if you don’t have a metal roof, or if you don’t have a metal roof that you want to replace, you have many other alternatives. Your roofing contractor can tell you what other roofing alternatives you have, and how these options compare to EPDM rubber roofing. The bottom line is that EPDM rubber roofing will work for most building and construction scenarios if they are used in conjunction with other materials and construction techniques.
If you want the absolute best protection against hail, you should consider the use of EP/EPDM rubber roofing. This type of roofing has been specifically designed to deal with hail. It consists of a base sheet made of ethylene propylene diene terpolymer. The roofing components are then coated in a polyester urethane. When dry, the polyester urethane forms a protective film on top of the base sheet. EP/EPDM rubber roofing will resist hail impacts by reducing the rate of expansion. This will keep the base sheet from expanding and contracting more than about 0.5 millimeters every two seconds, instead of the 10 to 15 millimeters that is typical with other roofing materials. The downside is that EP/EPDM rubber roofing is not waterproof. This means that it will leak in wet conditions, unless special preparations have been made to prevent it from doing so. If you plan to use EP/EPDM rubber roofing for an agricultural building, you can set it in a wet environment and it will not drip.
It is likely that you will want to use EP/EPDM rubber roofing for an industrial building. The roof will have a very low coefficient of thermal expansion, which will result in the roof not contracting and expanding more than about 0.5 millimeters every two seconds. This is not a problem for EP/EPDM rubber roofing, because when it is installed the roof will be covered with a dielectric, which will prevent it from contracting and expanding.
If you are building a warehouse, agricultural building, or other building that is similar to the type of building covered in an EP/EPDM rubber roof, you can add a spray foam insulation board below it. The spray foam board will be installed in exactly the same way as the base sheet, and the spray foam insulation will be glued to it. The spray foam insulation will be placed in the same way as in the factory roof. When the spray foam insulation is placed in the same way as in the factory roof, the base sheet will expand to fill the space between the spray foam insulation and the base sheet.
The spray foam insulation installed below the spray foam roof will form a nearly impervious barrier against any moisture that may seep in, and water will run through the spray foam roof without getting into the spray foam insulation.
The roofing materials will not be waterproof as a result of the spray foam insulation, but that will not matter if the spray foam roof is installed in a spray foam roofing installation method.
