Imagine, you are standing on the sidewalk, watching an average home . You see the connection, the windows, the front door, and the way up, you see the roof. Has the roof has asphalt shingles? Wood shakes perhaps? Perhaps it is made of metal or rubber tiles? What you see is where the attention goes, but that's what you do not see that really matters. There's more to cover that meets the eye. So let's talk about what happens, under the tiles.
The Roof Deck
We learn to crawl before you walk, so that when it comes to covers start with the starting point, the roof surface which is made of wood. Your wooden roof deck is comparable to a body metal cars. It is installed on top of the home base frame to give a surface on which to install shingles. Without a roof deck installed on your home, there would be no place to install the shingles. And, of course, without the tiles, your roof terrace would rot due to exposure to sun, rain, snow and ice and etc ... it is not a comfortable home at all!
The newer houses, sheets of plywood or OSB are fixed on top of the wooden trusses in your attic to form the roof deck. Plywood or OSB panels are installed in a staggered formation with small spaces between them to allow the wood to expand and contract as the wood is heated in summer and cools down in winter. older homes often have lengths of 2 "x 6" installed instead of plywood or OSB. When it comes time for you to replace the cover system, remember to have your contractor Calgary Roofing replace any and all damaged wood.
Remember, if the roof deck is rotting or damaged in any way, people walking on the roof could potentially crack or break through the forest, causing further damage to the roof system, so the tiles .. . and the person who was walking on it! However, most of the platforms of the roof can withstand a bit 'exposure to water or ice before it must be replaced.
Metal: Drip Edge and Rake edge
raised edge and rake board is the first part of the roof system to be installed. It is a long and narrow piece of metal that is installed along each end of your Deck roof, that is to say, along the eaves through and along the gable ends.
some area local building codes require the installation of Drip edge and rake EDGE codes and other buildings do not. Check with your local building city offices to find out. In Alberta, for example, the building code does not require the installation of raised edge or the Rake edge. Therefore many new houses and / or low budget roofing systems have not raised edge installed so as to allow for the roof more affordable prices. It is recommended, however, that the raised edge and rake board be installed on any roof system, with no exceptions.
drip edge and rake is available in a variety of colors and sizes and can be tailored to the needs of the roof system. Installing a proper drip edge often saves hundreds and sometimes even thousands of dollars when the roof system needs replaced.
If the roof system does not currently have installed drip edge or rake, do not panic, you can survive quite well. Just be aware that if your roof needs replacing, the roofing contractor may need to replace some of your wooden roof deck on an as needed basis.
Metal: Chimneys and skylights
Probably the most important part of any complete roof system. The metal installed in the valleys, chimneys and skylights to take the weight of the water flow on every roof. Poorly installed, a new roof system can make a living off of your living room waterfall.
Each chimney and skylight needs to what is defined as "a pot again", which consists of sheet metal bent at about a 0 degree angle (depending on the slope of the roof) and slips under the tiles and up under the siding, stucco or counter flashing on chimney or skylight. Each of the back panel needs a small "of protruding metal 1" 2 or more on both sides of the chimney or skylight to divert water away from the corners. The water should hit the rear metal pan and be directed away on both sides where it can continue to swing in the eaves trough.
Metal: Valleys
In the same way water flows through the valleys between two mountains, the water runs along the valleys on your roof peaks. Valleys generally receive the highest concentration of water flowing through them, and then correctly install is extremely important!
As mentioned in the section Leak Barrier, valleys have sealing barriers installed below them. Although some building codes do not require such a barrier loss to install, it is recommended to install an always in every valley.
A word of caution: Many entrepreneurs coverage install valleys in a style known as 'closed'. A valley closed consists of shingles tissues within the valley, as opposed to an 'open' valley, which has metal running from top to bottom. Both the 'closed' style installation 'open' and are acceptable for most building codes and by most manufacturers, however, the style 'open' installation has consistently out-performed the style 'closed' .. . and costs exactly the same price to install. Ask your roofing contractor to use the 'open' style installation for your roof valleys, this could save you from having to replace the roof system prematurely and also can avoid headaches in the long run. Typically, an 'open' valley is installed with a metal plate 30 gauge, 4 'wide, reaching 10' sheets. This metal can be ordered in any color to match the tiles on the roof system.
Leak Barrier
Think of a barrier to loss as a "second level" of protection for your roof deck. A backup plan, if you will, and also a protection against moisture accumulation. barriers of losses are almost always installed on the upper part of the Drip edge and metal rake edge along the eaves of valley areas, gable areas and valleys due to the risk these areas represent the presence of leaks, ice build, the deterioration gravel and the flow of water again.
If you've ever looked at your roof during the winter, you will notice how the ice and snow accumulates along the length of the eaves troughs and into the roof valleys. As with rake and Edge Drip edge, some building codes require barriers of loss to be installed and some building codes do not. In Alberta, the Building Code requires a Barrier loss to be installed on all of the valley gutter and valley areas of a roof system due to problems related to that snow and ice accumulation. As an optional upgrade, some roofing systems also have high sealing band barriers installed on top of the entire surface of the roof (as opposed to only along the special areas that we have just mentioned) where normally normally have been installed a roof deck protection standard.
Virtually all the roofs in Calgary, Alberta have installed sealing barriers, and many different types of sealing barriers are available in the market today, each with a different level of reliability, functionality and warranty and produced by many different manufacturers.
The choice of a suitable loss Barrier and installing them properly is an important step in any roofing system. Talk with your roofing contractor for more information on loss barriers, how to choose the right one and how to choose a professional roof contractor to install it.
Protection Roof Deck
Protection Roof Deck is very similar to a loss of barrier. The difference is that the protection of the platform roof is installed over the entire roof area of the Deck instead of only on "special areas", as we remember the section Leak Barrier.
Typically, the protection of the roof deck is a step lower in terms of quality of a loss of barrier. As with the barriers leak However, there are many different types of roof deck protection available to choose from ranging from the basic felt paper / tar for advanced plastic sheets woven and rip-proof material wrinkles. The choice of a reliable platform of the overhead guard is an important part of a quality roof system.
A word of caution; most front companies used felt paper as the roof deck protection. Although using felt paper is a standard and acceptable practice, some problems may arise if the paper gets wet felt during or after installation. Have you ever noticed how paper tends to curl when it dries after it was wet? In a similar way, felt paper may curl if water or excess moisture touches. For this reason, and because the cost is quite small, it is recommended to install a protection of the superior quality of the roof platform, such as a bridge Armour GAF / ELK. For a relatively small fee, you will be rewarded with a much more robust platform overhead guard.
Ask your contractor trusted local roof whose under-layer would be best for your roof any reason system.
