There's more to roofing than fulfills the eye. Let's talk about what goes on, under the shingles.
The Roof Deck
We find out to crawl prior to we walk, so when talking about roofing let's start with fresh start, the area of your roof which is made from wood. Your wood roofing deck is equivalent to an autos metal body. It is set up on top of the basic house frame to provide an area on which to install Shingles. Without a roofing system deck set up on your house, there would be nowhere to install your Shingles. And of course without the shingles, your roofing system deck would rot away due to direct exposure to the sun, snow, rain and ice and etc. not a comfy home at all!
On Newer Houses, sheets of plywood or OSB boards are attached on top of wood trusses in your attic to form the roofing system deck. Plywood or OSB boards are set up in a staggered formation with small spaces in between them to permit wood to expand and contract as the wood heats up in the summer and cools in the winter season. Older houses frequently have lengths of 2" x 6" set up rather of plywood or OSB board. When the time comes for you to replace your Roof System, remember to have your Calgary Roofing Contractor change any and all damaged wood.
Remember, if your roofing deck is decomposing or harmed in any method, individuals walking on your roof could possibly break or split through the wood, causing further damage to the roofing system, such as to the shingles ... and to the person who strolled on it! Most roofing decks can hold up against a little bit of exposure to water or ice prior to it needs to be replaced.
Metal: Drip Edge and Rake Edge
Leak edge and Rake edge is the first part of the Roofing system System to be set up. 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 location regional building codes require the setup of Drip Edge and Rake Edge and other structure codes do not. Contact your local city building workplaces to discover.

Every chimney and skylight requires what is referred to as "a back pan", which consists of sheet metal folded at around a 90 degree angle (depending upon the slope of your roofing system) and tucks under the shingles and up under the siding, stucco or counter flashing on the chimney or skylight. Every back pan requires 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.
Metal: Valleys
In the exact same way water runs along the valleys in between two mountains, water runs along the valleys on your roofing peaks. Valleys normally receive the greatest concentration of water flowing through them, for that reason installing them correctly is very essential!
As mentioned in the Leakage Barrier section, valleys have actually leak barriers set up below them. Despite the fact that some Structure Codes do not need such a leakage barrier to be installed, we recommend installing one constantly in every valley.

Ask your Roofing Contractor to utilize the 'open' design of installation for your roofs valleys, this could conserve you from having to replace your roof system prematurely and likewise can prevent headaches in the long run.

Leak Barrier
Consider a leakage barrier as a "second layer" of defense for your Roof Deck. A backup strategy, if you will, and also a defense against moisture develop. Drip barriers are nearly constantly installed on top of the Drip Edge and Rake Edge metal along eaves trough areas, gable areas and valleys since of the risk these locations present for leaks, ice develop, shingle wear and tear and water back circulation.
If you've ever taken a look at your roof during winter season, you'll notice how ice and snow develops along the length of your eaves troughs and inside the roofing valleys. Just Like Rake Edge and Drip Edge, some Structure codes require Leak Barriers to be set up and some Structure Codes do not. In Alberta, the Building regulations needs a leak Barrier to be installed on all eaves trough and valley locations of a Roof Systems since of concerns connected to such snow and ice develop up. As an optional upgrade, some high-end roof systems even have leakage barriers set up on top of the entire Roofing system Deck (rather than only along the special locations we simply mentioned) where typically a basic Roof Deck Security would usually have actually been installed.
