This article from the experts at IKO Roofing will assist you make sense of everything by highlighting the fundamental steps and describing the fundamental purpose for each roofing system component.
The next time you check out the bundle instructions or view a how-to video on YouTube, you'll have a better understanding of why roofing system shingles are set up the method they are. Working at heights on a roof presents fall threat dangers and other security issues. IKO advises that roofing work be done by qualified professionals who know the very best method to shingle a roofing and have been completely trained in all aspects of roofing system building and construction safety.
Asphalt roof shingles just count on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roof parts are organized and overlapped with this in mind, the roofing system must effectively shed water. In the dictionary, "to shingle" is specified as "to lay out or set up so as to overlap." So now let's take a look at the series of overlapping roof building and construction components to see how this uses.
Having a clean, flat deck surface area will assist guarantee that the recently shingled roof will likewise appear smooth and flat when ended up. Not just are we working from the bottom of the roof, we're likewise starting with the bottom-most layer, in terms of roofing components - installing shingles. The asphalt roofing shingles are the noticeable part and the very first line of defense versus severe weather, however what's underneath them truly counts.
It literally supplies a tidy, sharp edge for the start of the roofing system and safeguards the lower edge of the roof deck from water damage by preventing water from "defying gravity" and wicking back "up" before it leaves the roofing. Drip 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 part and it gets installed over the drip edge. Ice dam formation is finest prevented by having a proper attic vapor barrier, sufficient attic insulation and extensive ventilation; however, an ice protection membrane is a sensible roof element and is most likely needed by your local structure code in cold climates.
To be fully effective, it ought to extend up the roof to a point at least 24 inside the vertical extension of the interior side of the wall. At this time, any valleys on the roofing should likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes deal with the principle that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, including an extra degree of water-shedding security.
Both offer you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are many benefits to installing 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 installed at the bottom of the roofing system? When increasing the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping concept, setting up the drip edge over the underlayment at the rakes produces a tidy roof edge and supplies the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment offers your roofing system secondary layer of protection. house shingles. If a roofing is going to leakage, it will more than likely occur wherever the shingle layer is penetrated, disrupted or fulfills a wall. These are the special locations that require flashing an included layer of water-shedding product to help keep the water running downslope.
If your roofing system will have open valleys, which IKO advises, now is when the valleys ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed during shingle installation. For longer roof efficiency, IKO strongly recommends open metal valleys. Complete the application of underlayment and valley flashing prior to the roof shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The item is tacked in place temporarily along one edge. Carefully peel away the support, and put it in place, raveling any wrinkles. Start working from the eave, enabling additional pieces to overlap by at least 150 mm (6 ).
