When it's time to replace your roofing, the amount of info offered can be overwhelming. Great deals of websites and videos enter into excellent information on how to shingle a roof. This post from the experts at IKO Roofing will help you make sense of all of it by highlighting the standard steps and describing the essential purpose for each roof component.
The next time you check out the package instructions or view a how-to video on YouTube, you'll have a much better understanding of why roofing system shingles are set up the method they are. Operating at heights on a roof provides fall hazard risks and other safety issues. IKO recommends that roofing work be done by qualified experts who know the very best way to shingle a roofing and have been completely trained in all elements of roofing building 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 system elements are arranged and overlapped with this in mind, the roof needs to successfully shed water. In the dictionary, "to shingle" is defined as "to lay out or set up so as to overlap." So now let's take a look at the sequence of overlapping roof construction elements to see how this uses.
Having a clean, flat deck surface area will assist make sure that the recently shingled roof will also appear smooth and flat when finished. Not only are we working from the bottom of the roofing, we're likewise starting with the bottom-most layer, in regards to roof parts - replacing shingles. The asphalt roofing shingles are the noticeable part and the first line of defense against harsh weather, but what's beneath them actually counts.
It literally provides a clean, sharp edge for the start of the roofing and secures the lower edge of the roofing deck from water damage by avoiding water from "levitating" and wicking back "up" prior to it leaves the roof. 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 development is finest prevented by having a proper attic vapor barrier, adequate attic insulation and extensive ventilation; nevertheless, an ice security membrane is a wise roof part and is likely needed by your local building code in cold environments.
To be fully reliable, it must extend up the roof 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 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 covering seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding defense.
Both provide you peace-of-mind protection below the shingles. While the asphalt shingles will be the main water-shedding roofing system layer, there are lots of benefits to installing 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.
Keep 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 seems to oppose the overlapping principle, installing the drip edge over the underlayment at the rakes develops a clean roofing edge and supplies the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment gives your roofing system secondary layer of defense. asphalt roof shingles. If a roofing is going to leakage, it will most likely take place wherever the shingle layer is permeated, disturbed or fulfills a wall. These are the special areas that require flashing an added layer of water-shedding product to assist keep the water running downslope.
If your roof will have open valleys, which IKO advises, now is when the valleys need to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished during shingle installation. For longer roof performance, IKO strongly suggests 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 briefly along one edge. Thoroughly peel away the backing, and put it in place, raveling any wrinkles. Start working from the eave, enabling extra pieces to overlap by at least 150 mm (6 ).
