When it's time to replace your roofing system, the amount of info readily available can be overwhelming. Great deals of websites and videos enter into great information on how to shingle a roof. This article from the specialists at IKO Roof will assist you make sense of everything by highlighting the basic actions and outlining the basic purpose for each roof system part.
The next time you read the package directions or watch a how-to video on YouTube, you'll have a much better understanding of why roofing shingles are set up the method they are. Working at heights on a roofing provides fall risk dangers and other safety issues. IKO advises that roofing work be done by qualified specialists who know the finest way to shingle a roofing system and have been fully trained in all aspects of roofing system building security.
Asphalt roofing shingles just count on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing system components are set up and overlapped with this in mind, the roofing needs to successfully shed water. In the dictionary, "to shingle" is specified as "to set out or arrange so as to overlap." So now let's look at the sequence of overlapping roofing building and construction parts to see how this applies.
Having a tidy, flat deck surface will assist ensure that the recently shingled roofing will also appear smooth and flat when finished. Not only are we working from the bottom of the roof, we're likewise beginning with the bottom-most layer, in terms of roofing elements - asphalt roof shingles. The asphalt roofing shingles are the visible part and the very first line of defense against severe weather, however what's below them really counts.
It actually supplies a tidy, sharp edge for the start of the roof and protects the lower edge of the roofing deck from water damage by preventing water from "levitating" and wicking back "up" prior to it leaves the roof. 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 component and it gets set up over the drip edge. Ice dam development is finest avoided by having an appropriate attic vapor barrier, adequate attic insulation and thorough ventilation; however, an ice defense membrane is a smart roofing system component and is most likely needed by your local building code in cold climates.
To be totally reliable, it should 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 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 coating seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding defense.
Both offer you peace-of-mind protection below the shingles. While the asphalt shingles will be the main water-shedding roofing system 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.
Bear in mind that drip edge we set up at the bottom of the roof? When increasing the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping principle, installing the drip edge over the underlayment at the rakes produces a tidy roof edge and supplies the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment gives your roof secondary layer of defense. house shingles. If a roofing system is going to leak, it will most likely occur anywhere the shingle layer is permeated, interrupted or meets 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 advises, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle setup. For longer roofing system efficiency, IKO highly advises open metal valleys. Total the application of underlayment and valley flashing before the roofing shingles are used.
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. Thoroughly peel away the support, and put it in location, smoothing out any wrinkles. Start working from the eave, enabling additional pieces to overlap by a minimum of 150 mm (6 ).
