When it's time to change your roof, the quantity of information readily available can be overwhelming. Great deals of sites and videos enter into terrific detail on how to shingle a roof. This short article from the experts at IKO Roof will help you make sense of all of it by highlighting the fundamental steps and laying out the essential function for each roof system component.
The next time you read the bundle directions or enjoy a how-to video on YouTube, you'll have a much better understanding of why roofing shingles are set up the way they are. Working at heights on a roof provides fall danger dangers and other security issues. IKO advises that roof work be done by certified experts who understand the finest way to shingle a roof and have been completely trained in all elements of roofing system building security.
Asphalt roof shingles merely depend on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing parts are set up and overlapped with this in mind, the roof should successfully shed water. In the dictionary, "to shingle" is defined as "to set out or arrange so as to overlap." So now let's take a look at the series of overlapping roofing building elements to see how this applies.
Having a tidy, flat deck surface will assist make sure that the recently shingled roofing system will likewise appear smooth and flat when completed. Not just are we working from the bottom of the roofing, we're also starting with the bottom-most layer, in terms of roofing components - house shingles. The asphalt roofing shingles are the noticeable part and the first line of defense versus harsh weather, but what's beneath them actually counts.
It literally offers a clean, sharp edge for the start of the roof and protects the lower edge of the roofing system deck from water damage by avoiding water from "defying gravity" and wicking back "up" prior to it leaves the roofing system. Drip 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 element and it gets installed over the drip edge. Ice dam formation is finest avoided by having a proper attic vapor barrier, sufficient attic insulation and thorough ventilation; however, an ice defense membrane is a wise roof component and is likely required by your local building regulations in cold climates.
To be fully effective, it ought to 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 system need to likewise 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 finish seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding defense.
Both provide you peace-of-mind security below the shingles. While the asphalt shingles will be the primary water-shedding roofing system layer, there are lots of 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 set up at the bottom of the roofing? When increasing the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping concept, setting up the drip edge over the underlayment at the rakes develops a clean roofing edge and provides the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment provides your roofing secondary layer of security. replacing shingles. If a roofing system is going to leak, it will probably happen wherever the shingle layer is permeated, interrupted or fulfills 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 roofing system 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 during shingle installation. For longer roofing system efficiency, IKO highly recommends open metal valleys. Complete the application of underlayment and valley flashing prior to the roof shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The item is tacked in place briefly along one edge. Carefully 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 ).
