When it's time to replace your roofing system, the amount of details available can be frustrating. Great deals of websites and videos go into great information on how to shingle a roofing system. This article from the specialists at IKO Roofing will assist you make sense of all of it by highlighting the basic steps and outlining the essential function for each roof part.
The next time you check out the plan directions or enjoy a how-to video on YouTube, you'll have a far better understanding of why roof shingles are installed the way they are. Operating at heights on a roofing presents fall danger dangers and other security concerns. IKO advises that roofing work be done by qualified professionals who know the very best method to shingle a roofing and have been fully trained in all elements of roofing system building security.
Asphalt roofing shingles simply rely on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roof parts are arranged and overlapped with this in mind, the roofing ought to effectively shed water. In the dictionary, "to shingle" is specified as "to set out or set up so regarding overlap." So now let's take a look at the sequence of overlapping roofing system building and construction parts to see how this applies.
Having a clean, flat deck surface area will help ensure that the recently shingled roofing will also appear smooth and flat when completed. Not only are we working from the bottom of the roofing system, we're also starting with the bottom-most layer, in terms of roof elements - installing shingles. The asphalt roofing system shingles are the noticeable part and the first line of defense against severe weather, however what's beneath them truly counts.
It literally supplies a tidy, sharp edge for the start of the roofing and safeguards the lower edge of the roof deck from water damage by preventing 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 component and it gets set up over the drip edge. Ice dam development is best prevented by having a proper attic vapor barrier, appropriate attic insulation and comprehensive ventilation; nevertheless, an ice defense membrane is a sensible roof element and is most likely needed by your regional building regulations in cold environments.
To be fully reliable, it needs to 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 work on 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 use you peace-of-mind security underneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are many advantages to setting up 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.
Bear in mind that drip edge we set up at the bottom of the roofing? When increasing the sloped edges of the roof (called the "rakes") it goes on top of the underlayment. Although this appears to oppose the overlapping principle, installing the drip edge over the underlayment at the rakes creates a tidy roofing system edge and provides the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment gives your roofing secondary layer of protection. replacing shingles. If a roofing system is going to leak, it will most likely occur wherever the shingle layer is permeated, cut off or meets a wall. These are the unique areas that require flashing an included 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 ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle installation. For longer roof efficiency, IKO highly suggests open metal valleys. Complete the application of underlayment and valley flashing prior to 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 added 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 extra pieces to overlap by at least 150 mm (6 ).
