When it's time to replace your roof, the amount of details readily available can be overwhelming. Great deals of sites and videos enter into terrific information on how to shingle a roofing. This article from the professionals at IKO Roofing will help you understand everything by highlighting the standard steps and detailing the basic function for each roofing system component.
The next time you read the bundle instructions or enjoy a how-to video on YouTube, you'll have a better understanding of why roofing system shingles are set up the way they are. Working at heights on a roof provides fall threat dangers and other security concerns. IKO suggests that roofing work be done by qualified experts who know the finest method to shingle a roofing and have actually been completely trained in all aspects of roofing building and construction safety.
Asphalt roof shingles simply depend on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing elements are set up and overlapped with this in mind, the roof needs to effectively shed water. In the dictionary, "to shingle" is defined as "to set out or set up so regarding overlap." So now let's look at the sequence of overlapping roofing building and construction components to see how this uses.
Having a tidy, flat deck surface area will help ensure that the newly shingled roofing system will similarly appear smooth and flat when completed. Not only are we working from the bottom of the roofing, we're likewise beginning with the bottom-most layer, in terms of roofing components - asphalt roof shingles. The asphalt roofing shingles are the visible part and the first line of defense versus harsh weather, however what's underneath them truly counts.
It literally supplies a clean, sharp edge for the start of the roofing and safeguards the lower edge of the roofing deck from water damage by preventing water from "defying gravity" and wicking back "up" prior to 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 set up over the drip edge. Ice dam formation is best prevented by having a correct attic vapor barrier, appropriate attic insulation and thorough ventilation; nevertheless, an ice defense membrane is a wise roof component and is most likely needed by your local building code in cold environments.
To be fully efficient, it should extend up the roofing 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 must also be flashed with an ice and water membrane. Why an ice and water protector? Due to the fact that these membranes work on the concept that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, adding an extra degree of water-shedding protection.
Both use you peace-of-mind defense underneath the shingles. While the asphalt shingles will be the main water-shedding roofing layer, there are numerous advantages to setting up a roofing system 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 installed at the bottom of the roofing? When going up 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 develops a clean roofing edge and offers the underlayment attachment with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment offers your roofing secondary layer of protection. asphalt roof shingles. If a roof is going to leak, it will most likely occur wherever the shingle layer is penetrated, disrupted or fulfills a wall. These are the special locations that require flashing an included layer of water-shedding product to help keep the water running downslope.
If your roofing system will have open valleys, which IKO suggests, now is when the valleys should be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle setup. For longer roof performance, IKO highly advises open metal valleys. Complete 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 tacked in place momentarily along one edge. Carefully peel away the backing, and put it in location, smoothing out any wrinkles. Start working from the eave, allowing additional pieces to overlap by at least 150 mm (6 ).
