The Roof Deck
We learn to crawl before we walk, so when talking about roofing let's start with square one, the surface area of your roof which is made of wood. Your wood roof deck is comparable to an automobiles metal body. It is installed on top of the basic house frame to give a surface area on which to install Shingles. Without a roof deck installed on your house, there would be nowhere to install your Shingles. And of course without the shingles, your roof deck would rot away due to exposure to the sun, rain, snow and ice and etc...not a comfortable home at all!
On Newer Houses, sheets of plywood or OSB boards are fastened on top of wooden trusses in your attic to form the roof deck. Plywood or OSB boards are installed in a staggered formation with small spaces between them to allow wood to expand and contract as the wood heats in the summer and cools in the winter. Older homes often have lengths of 2" x 6" installed instead of plywood or OSB board. When the time comes for you to replace your Roof System, remember to have your Calgary Roofing Contractor replace any and all damaged wood.
Remember, if your roof deck is rotting or damaged in any way, people walking on your roof could potentially crack or break through the wood, causing further damage to the roof system, such as to the shingles...and to the person who walked on it! However, most roof decks can withstand a little bit of exposure to water or ice before it needs to be replaced.
Metal: Drip Edge and Rake Edge
Drip edge and Rake edge is the first part of the Roof System to be installed. It is a long and narrow piece of metal which is installed along each end of your Roof Deck, ie: along the eaves trough and along the gable ends.
Some area local building codes require the installation of Drip Edge and Rake Edge and other building codes do not. Check with your local city building offices to find out. In Alberta for example, the Building Code does not require the installation of Drip edge or Rake edge. Therefore many new homes and/or low budget roof systems do not have drip edge installed in order to allow for more affordable roof prices. We recommend however that Drip edge and Rake edge be installed on every Roof System, no exceptions.
Drip and Rake edge is available in a variety of different colors and sizes and can be custom built for the needs of your roof system. Installing an appropriate drip edge often saves hundreds and sometimes even thousands of dollars when your roof system needs replaced.
If your Roof System does not currently have drip or rake edge installed, do not panic, you'll survive well enough. Just be aware that when your roof needs to be replaced, the Roofing Contractor you may need to replace some of your wood Roof Deck on an as needed basis.
Metal: Chimneys and Skylights
Arguably the most important part of every complete roof system. The metal installed in the valleys, chimneys and skylights take the brunt of water flow on every roof. Poorly installed, a brand new roof system can make a waterfall out of your living room.
Every chimney and skylight needs what is referred to as "a back pan", which consists of sheet metal folded at around a 90 degree angle (depending on the slope of your roof) and tucks under the shingles and up under the siding, stucco or counter flashing on the chimney or skylight. Every back pan needs a small 2" section of metal sticking out 1" or more from either side of the chimney or skylight to divert water away from the corners. Water should hit the metal back pan and be directed away on either side where it can continue its run into the eaves trough.
In the same way water runs along the valleys between two mountains, water runs along the valleys on your roof peaks. Valleys generally receive the highest concentration of water flowing through them, therefore installing them correctly is extremely important!
As mentioned in the Leak Barrier section, valleys have leak barriers installed underneath them. Even though some Building Codes do not require such a leak barrier to be installed, we recommend installing one always in every valley.
A word of caution: Many roofing contractors install valleys in a style referred to as 'closed'. A closed valley consists of Shingles woven inside the valley, as opposed to an 'open' valley which has sheet metal running from top to bottom. Both the 'open' and the 'closed' style of installation are acceptable by the most Building Codes and by most manufacturers, however, the 'open' style installation has consistently outperformed the 'closed' style...and costs exactly the same price to install. Ask your Roofing Contractor to use the 'open' style of installation for your roofs valleys, this could save you from having to replace your roof system prematurely and also can avoid headaches in the long run. Typically, an 'open' valley is installed with a 30 gauge sheet metal, 4' wide, coming in 10' sheets. This metal can be ordered in any color to match the shingles on your roof system.
Another discovery you have made was that, it was not the house itself, that was magnificent, in fact the house was rather average, but it was the metal roof that made the house look like a million bucks.
Perhaps you were not a believer just yet, but there was something that has shifted in your view towards metal roofing, the old barn metal roofing prejudice was evaporating, and the new curious interest in metal roofing was born. You told your friends about the metal roof you saw, and they were quite surprised to hear about it. All but one of them, did not have much to say about it. But, a friend of yours who tried to tell you about benefits of metal roofs before, said "See, bud, you were making fun of it, and now you are all excited about it." Indeed, your views were beginning to change. In fact, you were now becoming so curious about metal roofing that you decided to speak with a knowledgeable contractor who installs metal roofing.
Not your typical roofing job
Your friend told you that metal roofing installation is totally different form conventional roofing and that your regular roofer does not know how to install a metal roof. In fact, he told you a story of man who had conventional roofing contractor install a metal roof for somebody he knew and it was a disaster. Roofing contractor who did the installation did not know what he was doing and performed an incorrect installation. As a result, the roof was leaking badly, and a new experienced metal roofer had to be brought on the job to undo the damage, and reinstall the system from a scratch. Your friend explained to you that people who claim that metal roofing is easier to install than a conventional roof, have never installed one, and use hearsay as their frame of reference, Their misguided beliefs confuse other people and cost industry a lot money in poor and sometimes outright wrong quality of roofing installation.
If you want it done right, then you better find a contractor who is certified and specializes in metal.
The moral of your friend's story and its lesson was clear, it is better to invest time and energy to find a qualified metal roofing contractor to install your roof in the first place than, it is to hire the wrong crew that has never installed a metal roof before, and will treat it as another asphalt shingle "get it done in one day" project. Now, that there were no questions remaining as to the importance of hiring a roofing company that specializes in metal roofing, your friend advised you to use a Roofing Contractors directory broken down into categories by specialties; metal roofing contractor companies organized by location in the U.S, and by specialty categories such as standing seam and metal shingle installers.
