When it's time to change your roof, the amount of details offered can be frustrating. Lots of websites and videos enter into excellent information on how to shingle a roofing system. This post from the professionals at IKO Roofing will assist you understand everything by highlighting the basic steps and describing the fundamental purpose for each roof system element.
The next time you check out the bundle directions or view a how-to video on YouTube, you'll have a much better understanding of why roofing system shingles are installed the method they are. Working at heights on a roof provides fall risk risks and other security concerns. IKO advises that roofing work be done by qualified specialists who understand the best method to shingle a roofing and have actually been fully trained in all elements of roofing construction security.
Asphalt roof shingles just depend on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roof parts are set up and overlapped with this in mind, the roofing must effectively shed water. In the dictionary, "to shingle" is defined as "to lay out or arrange so as to overlap." So now let's look at the series of overlapping roofing system construction parts to see how this applies.
Having a tidy, flat deck surface area will help make sure that the freshly shingled roofing will similarly appear smooth and flat when finished. Not just are we working from the bottom of the roof, we're also beginning with the bottom-most layer, in terms of roof elements - house shingles. The asphalt roofing shingles are the noticeable part and the very first line of defense versus inclement weather, but what's beneath them actually counts.
It actually offers a clean, sharp edge for the start of the roofing system and secures the lower edge of the roof deck from water damage by avoiding 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 element and it gets installed over the drip edge. Ice dam formation is best prevented by having a correct attic vapor barrier, adequate attic insulation and thorough ventilation; nevertheless, an ice protection membrane is a smart roof part and is likely required by your regional building code in cold environments.
To be fully effective, it should extend up the roofing system 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 should also be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes deal with the concept that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding security.
Both use you peace-of-mind protection underneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are lots of benefits to installing a roof underlayment. The felt is laid in horizontal courses, overlapping the eave ice and water protector by 4 and the valley membrane flashing by 6.
Remember that drip edge we set up at the bottom of the roof? When going up the sloped edges of the roof (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping principle, setting up the drip edge over the underlayment at the rakes creates a tidy roofing edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment offers your roof secondary layer of security. house shingles. If a roof is going to leak, it will more than likely occur wherever the shingle layer is permeated, cut off or satisfies a wall. These are the unique areas that need flashing an included layer of water-shedding material to help keep the water running downslope.
If your roofing 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 setup. For longer roofing performance, IKO strongly recommends 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 place briefly along one edge. Carefully peel away the support, and put it in location, smoothing out any wrinkles. Start working from the eave, enabling extra pieces to overlap by at least 150 mm (6 ).
