When it's time to change your roofing, the amount of details offered can be overwhelming. Lots of sites and videos enter into great information on how to shingle a roof. This post from the experts at IKO Roof will help you make sense of it all by highlighting the basic steps and detailing the essential function for each roof system element.
The next time you check out the bundle guidelines or view a how-to video on YouTube, you'll have a better understanding of why roofing system shingles are installed the way they are. Working at heights on a roofing system provides fall danger dangers and other security concerns. IKO recommends that roofing work be done by certified experts who understand the best way to shingle a roofing system and have been fully trained in all aspects of roofing system construction security.
Asphalt roof shingles just rely on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing elements are arranged and overlapped with this in mind, the roof must successfully shed water. In the dictionary, "to shingle" is specified as "to lay out or arrange so as to overlap." So now let's take a look at the series of overlapping roof building and construction parts to see how this applies.
Having a tidy, flat deck surface area will assist make sure that the newly shingled roofing will also appear smooth and flat when ended up. Not only are we working from the bottom of the roofing system, we're also starting with the bottom-most layer, in terms of roof parts - installing shingles. The asphalt roof shingles are the noticeable part and the very first line of defense versus harsh weather, however what's below them actually counts.
It actually provides a clean, sharp edge for the start of the roofing and safeguards the lower edge of the roofing system deck from water damage by preventing water from "levitating" and wicking back "up" prior to it leaves the roofing. 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 formation is finest prevented by having a correct attic vapor barrier, sufficient attic insulation and thorough ventilation; nevertheless, an ice security membrane is a wise roofing system component and is most likely required by your regional building regulations in cold climates.
To be completely effective, it should extend up the roof 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 system must likewise be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes deal with the principle that their rubberized asphalt finish seals around the shanks of the overlying shingle fasteners, adding an extra degree of water-shedding security.
Both provide you peace-of-mind security beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are many advantages to setting up a roofing system underlayment. The felt is laid in horizontal courses, overlapping the eave ice and water protector by 4 and the valley membrane flashing by 6.
Bear in mind that drip edge we set up at the bottom of the roof? When increasing the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to oppose the overlapping principle, setting up the drip edge over the underlayment at the rakes produces a tidy roof edge and provides the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment gives your roof secondary layer of protection. asphalt roof shingles. If a roofing is going to leak, it will most likely happen anywhere the shingle layer is permeated, cut off or fulfills a wall. These are the unique locations that require flashing an included layer of water-shedding product to help keep the water running downslope.
If your roofing will have open valleys, which IKO recommends, now is when the valleys need to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle setup. For longer roof efficiency, IKO highly suggests open metal valleys. Total 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 item is added in location temporarily along one edge. Thoroughly peel away the support, and put it in place, smoothing out any wrinkles. Start working from the eave, allowing additional pieces to overlap by at least 150 mm (6 ).
