When it's time to replace your roofing, the quantity of information available can be overwhelming. Great deals of sites and videos enter into terrific information on how to shingle a roofing. This short article from the professionals at IKO Roofing will help you understand it all by highlighting the standard actions and detailing the essential function for each roofing system element.
The next time you check out the plan directions or see a how-to video on YouTube, you'll have a better understanding of why roof shingles are installed the way they are. Working at heights on a roofing presents fall danger dangers and other security issues. IKO advises that roof work be done by certified professionals who understand the finest way to shingle a roofing and have been fully trained in all elements of roofing system building and construction security.
Asphalt roof shingles merely count on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing system components are set up and overlapped with this in mind, the roofing should successfully shed water. In the dictionary, "to shingle" is specified as "to lay out or arrange so as to overlap." So now let's take a look at the series of overlapping roofing system building and construction parts to see how this uses.
Having a clean, flat deck surface area will assist ensure that the freshly shingled roof will also appear smooth and flat when completed. Not just are we working from the bottom of the roof, we're likewise beginning with the bottom-most layer, in regards to roof components - installing shingles. The asphalt roofing system shingles are the noticeable part and the first line of defense versus inclement weather condition, however what's underneath them actually counts.
It actually provides a clean, sharp edge for the start of the roofing system and protects 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 system. 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 part and it gets set up over the drip edge. Ice dam development is finest prevented by having a proper attic vapor barrier, sufficient attic insulation and comprehensive ventilation; nevertheless, an ice defense membrane is a smart roofing system element and is likely required by your regional building regulations in cold environments.
To be totally effective, it must 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 system should likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes deal with the concept that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, including an extra degree of water-shedding security.
Both offer you peace-of-mind defense underneath the shingles. While the asphalt shingles will be the main water-shedding roof 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.
Bear in mind that drip edge we installed at the bottom of the roof? When going up the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping concept, installing the drip edge over the underlayment at the rakes produces a tidy roofing system edge and supplies the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment provides your roof secondary layer of defense. replacing shingles. If a roofing system is going to leakage, it will most likely occur anywhere the shingle layer is penetrated, disturbed or satisfies a wall. These are the unique areas that need flashing an included layer of water-shedding material to help keep the water running downslope.
If your roofing system will have open valleys, which IKO suggests, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle installation. For longer roofing system performance, IKO highly recommends open metal valleys. Complete the application of underlayment and valley flashing before the roofing shingles are used.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The product is tacked in place temporarily along one edge. Thoroughly peel away the support, 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 ).
