Imagine you are standing on the sidewalk, looking at the middle house. You see the siding, the windows, the front door and upstairs, you see the roof. Is there a roof of asphalt on the roof? Wood can shake? Maybe it is made of metal or rubber tiles? What you see is focused, but it is what you do not see that really matters. There is more roof than it seems at first glance. So let's talk about what's going on, under the shingles.
Roof
We learn to crawl before you go, so when it comes to roofs, start with a square, the surface area of your roof, made of wood. Your wooden roof on the roof is comparable to a metal car body. It is installed on top of the main frame of the house to give a surface on which to install tiles. Without a roof installed on your home, you must now install your tiles. And, of course, without a tile, your roof will rot due to exposure to the sun, rain, snow and ice, etc. ... not at all a comfortable house!
In newer homes, sheets of plywood or OSB slabs are mounted on top of wooden trusses in the attic to form a roof. Plywood or OSB boards are installed in a chessboard with small spaces between them so that the wood expands and contracts when the wood heats up in the summer and cools in the winter. Older homes are often 2 "x 6" long, installed instead of plywood or OSB. When it comes time to replace your roof system, remember that your Calgary roofing contractor will replace any damaged wood.
Remember that if your deck roof is rotting or damaged in any way, people walking along your roof can crack or burst through the forest, causing further damage to the roof system ... and to the one who walked along it! However, most roof decks can withstand a little exposure to water or ice before they need to be replaced.
Metal: drip edge and comb
The drip edge and rake edge are the first part of the installed roof system. This is a long and narrow piece of metal that is installed along each end of your roof, i.e. Along the eaves and along the ends.
Some local building codes require the installation of Drip Edge and Rake Edge, while other building codes do not. Check with local city buildings to find out. For example, in Alberta, the building code does not require the installation of droplet edges or rake edges. There are many new homes and / or low-cost roof systems that do not have a drip edge to provide a more affordable roof price. However, we recommend that the edges of the droplets and the edges of the rail be installed on each roof system without any exceptions.
The edge of the dropper and comb is available in various colors and sizes and can be custom made for your roof system. Installing a suitable drip edge often saves hundreds and sometimes thousands of dollars when your roof system needs to be replaced.
If your roof system currently does not have a drip or ridge edge, do not panic, you can withstand quite well. Just keep in mind that when your roof needs to be replaced, the roofing contractor may need to replace part of your wooden roof on any basis required.
Metal: chimneys and skylights
This is probably the most important part of the entire roof system. The metal, installed in the valleys, chimneys and lanterns, assumes the brunt of the flow of water on each roof. A poorly installed, new roof system can make a waterfall from your living room.
Each chimney and manhole requires a so-called “rear pan” consisting of sheet metal, folded at a 90 degree angle (depending on the slope of your roof) and rivets under the tiles and under siding, plaster or a counter blinking on the chimney or lumen. Each back pan requires a small 2-inch section of metal sticking out of 1 "or more on either side of the chimney or lumen to divert water from the corners. The water should strike the metal back pan and be directed on both sides where may continue its passage to the eaves.
Metal: Valleys
Similarly, the water passes through the valleys between two mountains, the water passes through the valleys on your roofs. The shafts usually get the highest concentration of water flowing through them, so their proper installation is extremely important!
As mentioned in the “Leakage Barrier” section, there are leakage obstacles in the valleys located under them. Despite the fact that some building codes do not require the installation of such a leak barrier, we recommend installing it always in each valley.
Warning: many roofing contractors install valleys in a style called “closed”. A closed valley consists of tiles interwoven inside the valley, in contrast to the open one, which has sheet metal that goes from top to bottom. And the "open" and "closed" installation style is acceptable by most building codes and most manufacturers, however, open & # 39; setting style consistently closes & # 39; style ... and it costs exactly the same price to install. Ask your roofing contractor to use the open & # 39; installation style for your roof valleys, it can save you from having to replace your roof system prematurely, and can also avoid heads in the long run. As a rule, open & quot; the valley is installed with sheet metal 30 mm thick, 4 inches wide, which is included in 10 pcs. sheets. This metal can be ordered in any color to match the tile on your roof.
Leakage barrier
Think of leakage barriers as a “second layer” of protection for your roof. Contingency plan, if you want, as well as moisture protection. Leakage barriers are almost always placed on top of the metal of the drip edge and edge ridge along the eaves through areas, areas and valleys, due to the risk these areas create for leaks, ice formation, deterioration of pebbles and back flow.
If you have ever looked at your roof in winter, you will notice how ice and snow build up along the length of your eaves and inside the roof valleys. As in the case of Rake Edge and Drip Edge, some building codes require the installation of restrictive barriers, and some building codes do not. In Alberta, in the Building Code, it is necessary to establish a barrier to leakage in all parts of the eaves and valleys of the roof of buildings due to the problems associated with the creation of such snow and ice. As an additional upgrade, some high-performance roof systems even have leakage barriers installed on top of the entire roof of the roof (as opposed to only those special areas that we just mentioned) where standard roof protection was usually installed.
Virtually all roofs in Calgary, Alberta have leakage barriers installed, and many different types of leakage barriers are available on the market today, each of which offers a different level of reliability, functionality and warranty and is manufactured by many different manufacturers.
Choosing the right leak barrier and installing it properly is an important step in every roof system. Talk to your roofing contractor to learn more about leakage barriers, how to choose the right one and how to choose a professional roofing contractor to install it.
Roof protection
The roof protection is very similar to a leak barrier. The difference is that the roof protection on the roof is installed on the entire roof area, and not just on “special zones”, as we will mention in the “Leakage barrier” section.
As a rule, roof protection on the deck is lower in quality than barrier leakage. As with insulation barriers, there are many different types of roof protection from the roof, which can be chosen from the height of the base melt / resin paper to advanced plastic woven sheets of tear material and wrinkles. Choosing reliable roof protection is an important part of a quality roof system.
Word of caution; most roofing companies use felt paper to protect the roof. Although the use of paper is a standard and acceptable practice, some problems may arise if the paper becomes wet during or after installation. Have you ever noticed how paper is curled when it dries after it is wet? Similarly, the felt paper can curl if it is touched by water or excessive moisture. For this reason, and also because the cost is rather low, we recommend installing better protection from the roof deck, such as the GAF / ELK deck. For a relatively small additional fee, you will be rewarded with much more reliable roof protection.
Ask your local trusted roofing contractor what type of underlayer is best for your roof system.
Conclusion
So, life benefits tile. See how much it costs behind the curtains? Professional roofing contractors have known this material inside and out and can greatly assist in ensuring the reliability of the roof system for many years. Product providers such as GAF / Elk and IKO can also answer specific questions about products.
All the best with your roofing project, and remember, be active, make educated decisions.
