When it's time to change your roof, the amount of details available can be overwhelming. Lots of websites and videos enter into fantastic information on how to shingle a roofing system. This article from the professionals at IKO Roofing will help you understand everything by highlighting the basic actions and describing the fundamental function for each roofing system part.
The next time you check out the plan guidelines or view a how-to video on YouTube, you'll have a better understanding of why roof shingles are set up the way they are. Operating at heights on a roof presents fall danger threats and other security concerns. IKO recommends that roofing work be done by qualified experts who know the best method to shingle a roofing and have actually been fully trained in all elements of roof construction security.
Asphalt roofing shingles just depend on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing elements are set up and overlapped with this in mind, the roofing system must effectively shed water. In the dictionary, "to shingle" is specified as "to set out or set up so as to overlap." So now let's look at the sequence of overlapping roofing system building and construction components to see how this applies.
Having a clean, flat deck surface area will assist ensure that the freshly shingled roof will also appear smooth and flat when completed. Not just are we working from the bottom of the roof, we're also beginning with the bottom-most layer, in regards to roof parts - asphalt roof shingles. The asphalt roofing shingles are the visible part and the very first line of defense versus inclement weather, however what's underneath them truly counts.
It actually supplies a tidy, sharp edge for the start of the roof and secures the lower edge of the roofing system deck from water damage by preventing water from "defying gravity" and wicking back "up" before it leaves the roof. Leak edge is installed under the ice and water at the eaves and on top of the ice and water and underlayment on the rakes.
This thin, self-adhering membrane is the next component and it gets installed over the drip edge. Ice dam development is best avoided by having a correct attic vapor barrier, sufficient attic insulation and thorough ventilation; however, an ice security membrane is a smart roof component and is likely required by your local structure code in cold environments.
To be totally efficient, it needs to extend up the roofing to a point a minimum of 24 inside the vertical extension of the interior side of the wall. At this time, any valleys on the roofing ought to likewise be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes work on the principle that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, adding an extra degree of water-shedding security.
Both use you peace-of-mind security below the shingles. While the asphalt shingles will be the primary water-shedding roofing layer, there are many advantages to setting up a roofing underlayment. The felt is laid in horizontal courses, overlapping the eave ice and water protector by 4 and the valley membrane flashing by 6.
Keep in mind that drip edge we installed at the bottom of the roofing? When increasing the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping concept, installing the drip edge over the underlayment at the rakes creates a clean roofing system edge and provides the underlayment attachment with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment provides your roofing secondary layer of security. house shingles. If a roof is going to leak, it will most likely take place anywhere the shingle layer is permeated, cut off or satisfies a wall. These are the special locations that need flashing an included layer of water-shedding product to assist keep the water running downslope.
If your roof will have open valleys, which IKO suggests, now is when the valleys need to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle installation. For longer roofing system performance, IKO strongly advises open metal valleys. Complete the application of underlayment and valley flashing before the roofing shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The product is tacked in place temporarily along one edge. Carefully peel away the support, and put it in place, smoothing out any wrinkles. Start working from the eave, allowing extra pieces to overlap by at least 150 mm (6 ).
