When it's time to replace your roofing, the amount of info available can be frustrating. Lots of websites and videos go into excellent information on how to shingle a roof. This article from the experts at IKO Roof will help you make sense of all of it by highlighting the fundamental actions and describing the basic purpose for each roof system element.
The next time you read the bundle instructions or enjoy a how-to video on YouTube, you'll have a much better understanding of why roofing shingles are installed the way they are. Working at heights on a roof presents fall hazard risks and other security issues. IKO suggests that roofing work be done by qualified experts who understand the finest method to shingle a roof and have been completely trained in all elements of roof construction security.
Asphalt roof shingles simply depend on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roof elements are set up and overlapped with this in mind, the roofing should effectively shed water. In the dictionary, "to shingle" is specified as "to lay out or arrange so regarding overlap." So now let's look at the sequence of overlapping roof building elements to see how this applies.
Having a tidy, flat deck surface area will help make sure that the freshly shingled roof will likewise appear smooth and flat when completed. Not just are we working from the bottom of the roof, we're likewise starting with the bottom-most layer, in regards to roof elements - replacing shingles. The asphalt roof shingles are the noticeable part and the first line of defense versus inclement weather condition, but what's beneath them actually counts.
It literally supplies a clean, sharp edge for the start of the roofing system and protects the lower edge of the roofing 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 formation is best prevented by having an appropriate attic vapor barrier, adequate attic insulation and extensive ventilation; nevertheless, an ice security membrane is a sensible roof element and is likely needed by your regional building regulations in cold climates.
To be completely efficient, 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? Because these membranes deal with the concept that their rubberized asphalt finishing seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding security.
Both provide you peace-of-mind defense below the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are lots of benefits to installing 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.
Keep in mind that drip edge we installed at the bottom of the roof? When increasing the sloped edges of the roof (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 creates a tidy roofing edge and offers the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment provides your roofing system secondary layer of protection. asphalt roof shingles. If a roofing system is going to leak, it will more than likely happen wherever the shingle layer is penetrated, cut off or fulfills a wall. These are the unique locations that need flashing an included layer of water-shedding product 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 setup. For longer roofing performance, IKO strongly 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 item is tacked in location briefly along one edge. Thoroughly peel away the backing, and put it in location, smoothing out any wrinkles. Start working from the eave, allowing extra pieces to overlap by at least 150 mm (6 ).
