When it's time to change your roofing system, the quantity of info readily available can be overwhelming. Great deals of websites and videos enter into excellent detail on how to shingle a roof. This post from the specialists at IKO Roof will assist you understand everything by highlighting the standard actions and laying out the essential function for each roof part.
The next time you read the package instructions or enjoy a how-to video on YouTube, you'll have a much better understanding of why roofing shingles are installed the method they are. Working at heights on a roofing system presents fall danger risks and other security concerns. IKO suggests that roof work be done by qualified professionals who understand the very best way to shingle a roofing system and have actually been fully trained in all aspects of roofing building security.
Asphalt roofing shingles just rely on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing parts are set up and overlapped with this in mind, the roofing needs to effectively shed water. In the dictionary, "to shingle" is defined as "to lay out or set up so as to overlap." So now let's take a look at the sequence of overlapping roofing system building and construction components to see how this uses.
Having a clean, flat deck surface area will assist guarantee that the newly shingled roof will similarly appear smooth and flat when ended up. Not only are we working from the bottom of the roofing, we're likewise starting with the bottom-most layer, in terms of roof elements - replacing shingles. The asphalt roofing system shingles are the noticeable part and the very first line of defense versus inclement weather, however what's below them really counts.
It literally offers a clean, sharp edge for the start of the roofing and secures the lower edge of the roof deck from water damage by avoiding water from "defying gravity" and wicking back "up" prior to it leaves the roofing system. 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 set up over the drip edge. Ice dam formation is best avoided by having a proper attic vapor barrier, appropriate attic insulation and extensive ventilation; however, an ice defense membrane is a smart roofing system component and is likely required by your regional building code in cold environments.
To be completely effective, it must 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 need to also be flashed with an ice and water membrane. Why an ice and water protector? Due to the fact that these membranes deal with the principle that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding defense.
Both use you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the primary water-shedding roofing 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 going up the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this seems to contradict the overlapping concept, setting up the drip edge over the underlayment at the rakes creates a tidy roof edge and supplies the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment offers your roofing system secondary layer of defense. replacing shingles. If a roof is going to leakage, it will probably happen any place the shingle layer is permeated, disrupted or fulfills a wall. These are the unique locations that require flashing an added layer of water-shedding product to help keep the water running downslope.
If your roof will have open valleys, which IKO suggests, now is when the valleys ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle setup. For longer roofing efficiency, IKO strongly 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 product is added in location temporarily along one edge. Carefully peel away the support, and put it in place, smoothing out any wrinkles. Start working from the eave, permitting additional pieces to overlap by a minimum of 150 mm (6 ).
