When it's time to change your roofing, the quantity of info offered can be frustrating. Great deals of sites and videos enter into terrific information on how to shingle a roof. This article from the specialists at IKO Roofing will assist you understand everything by highlighting the standard actions and laying out the basic purpose for each roof element.
The next time you read the bundle directions or see a how-to video on YouTube, you'll have a much better understanding of why roof shingles are set up the method they are. Working at heights on a roofing system provides fall risk risks and other security issues. IKO recommends that roofing work be done by qualified experts who know the very best way to shingle a roofing system and have actually been fully trained in all aspects of roofing system building and construction security.
Asphalt roof shingles just count on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing system parts are organized and overlapped with this in mind, the roofing ought to successfully shed water. In the dictionary, "to shingle" is specified as "to set out or organize so as to overlap." So now let's take a look at the series of overlapping roofing system building and construction parts to see how this uses.
Having a clean, flat deck surface area will assist make sure that the recently shingled roofing system will likewise appear smooth and flat when finished. Not just are we working from the bottom of the roofing, we're also starting with the bottom-most layer, in regards to roofing elements - installing shingles. The asphalt roofing shingles are the noticeable part and the very first line of defense versus harsh weather condition, however what's below them truly counts.
It actually provides a tidy, sharp edge for the start of the roofing system and protects the lower edge of the roofing system deck from water damage by preventing water from "levitating" and wicking back "up" prior to it leaves the roof. 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 component and it gets installed over the drip edge. Ice dam development is finest avoided by having a proper attic vapor barrier, adequate attic insulation and comprehensive ventilation; however, an ice protection membrane is a smart roofing system component and is most likely required by your local building regulations in cold environments.
To be completely effective, it must 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 system must likewise be flashed with an ice and water membrane. Why an ice and water protector? Because 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 protection.
Both provide you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are many benefits 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.
Remember 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 seems to contradict the overlapping concept, setting up the drip edge over the underlayment at the rakes creates a clean roof edge and provides the underlayment attachment with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment offers your roofing system secondary layer of defense. house shingles. If a roofing system is going to leak, it will most likely take place wherever the shingle layer is permeated, cut off or satisfies a wall. These are the special areas that need flashing an added layer of water-shedding material to assist keep the water running downslope.
If your roof 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 during shingle installation. For longer roof efficiency, IKO strongly advises open metal valleys. Complete the application of underlayment and valley flashing before the roof 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 location momentarily along one edge. Thoroughly peel away the support, and put it in place, raveling any wrinkles. Start working from the eave, permitting additional pieces to overlap by a minimum of 150 mm (6 ).
