When it's time to change your roofing, the amount of information offered can be frustrating. Great deals of sites and videos go into great information on how to shingle a roof. This post from the experts at IKO Roof will help you understand all of it by highlighting the standard actions and laying out the essential purpose for each roof 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 system shingles are installed the way they are. Working at heights on a roofing system presents fall hazard threats and other safety issues. IKO suggests that roofing work be done by qualified professionals who know the very best way to shingle a roofing system and have actually been fully trained in all aspects of roof building security.
Asphalt roofing shingles just rely on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing system elements are organized and overlapped with this in mind, the roof should successfully shed water. In the dictionary, "to shingle" is specified as "to set out or set up so as to overlap." So now let's look at the series of overlapping roofing construction elements to see how this uses.
Having a tidy, flat deck surface will assist guarantee 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 likewise beginning with the bottom-most layer, in regards to roofing elements - asphalt roof shingles. The asphalt roofing system shingles are the visible part and the first line of defense versus severe weather, however what's beneath them truly counts.
It literally supplies a tidy, sharp edge for the start of the roofing system and safeguards the lower edge of the roofing system deck from water damage by avoiding water from "levitating" and wicking back "up" before it leaves the roofing system. Leak edge is set up 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 development is finest avoided by having an appropriate attic vapor barrier, sufficient attic insulation and thorough ventilation; nevertheless, an ice protection membrane is a sensible roof system component and is most likely needed by your local building regulations in cold environments.
To be totally 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 ought to likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes work on the principle that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding security.
Both offer you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the main water-shedding roof 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 going up the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping principle, installing the drip edge over the underlayment at the rakes creates a tidy roofing system edge and supplies the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment gives your roofing secondary layer of defense. installing shingles. If a roofing is going to leakage, it will probably occur anywhere the shingle layer is permeated, disturbed or fulfills a wall. These are the special locations that require flashing an added layer of water-shedding product to help keep the water running downslope.
If your roofing will have open valleys, which IKO suggests, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle setup. For longer roof efficiency, IKO strongly suggests open metal valleys. Total the application of underlayment and valley flashing prior to the roof shingles are used.
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. Thoroughly peel away the support, and put it in place, raveling any wrinkles. Start working from the eave, allowing additional pieces to overlap by a minimum of 150 mm (6 ).
