When it's time to change your roofing system, the amount of information readily available can be overwhelming. Great deals of websites and videos go into fantastic information on how to shingle a roofing system. This article from the experts at IKO Roof will help you understand everything by highlighting the basic steps and describing the essential purpose for each roof system component.
The next time you read the plan guidelines or watch a how-to video on YouTube, you'll have a better understanding of why roofing shingles are installed the method they are. Operating at heights on a roofing system provides fall hazard risks and other security concerns. IKO suggests that roof work be done by certified experts who know the very best way to shingle a roof and have actually been completely trained in all aspects of roofing system building safety.
Asphalt roof shingles just depend on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roof parts are set up and overlapped with this in mind, the roofing 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 look at the sequence of overlapping roof construction elements to see how this applies.
Having a tidy, flat deck surface will assist guarantee that the recently shingled roof will likewise appear smooth and flat when finished. Not just are we working from the bottom of the roofing system, we're also beginning with the bottom-most layer, in terms of roof elements - replacing shingles. The asphalt roof shingles are the noticeable part and the very first line of defense against harsh weather, but what's underneath them really counts.
It actually supplies a clean, sharp edge for the start of the roof and safeguards the lower edge of the roof deck from water damage by avoiding water from "levitating" and wicking back "up" prior to 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 formation is finest prevented by having a proper attic vapor barrier, appropriate attic insulation and thorough ventilation; nevertheless, an ice protection membrane is a wise roof part and is likely required by your regional building regulations in cold climates.
To be totally effective, it needs to extend up the roofing system 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 need to also be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes work on the concept that their rubberized asphalt finish seals around the shanks of the overlying shingle fasteners, including an extra degree of water-shedding protection.
Both use you peace-of-mind security beneath the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are numerous 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.
Bear in mind that drip edge we set up at the bottom of the roofing system? When going up the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to oppose the overlapping concept, setting up the drip edge over the underlayment at the rakes creates a clean roof edge and provides the underlayment attachment with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment offers your roofing system secondary layer of defense. installing shingles. If a roofing system is going to leak, it will probably happen any place the shingle layer is penetrated, cut off or meets a wall. These are the special areas that need flashing an added 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 completed during shingle setup. For longer roofing performance, IKO highly suggests open metal valleys. Complete the application of underlayment and valley flashing before the roof shingles are used.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The item is added 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, enabling additional pieces to overlap by at least 150 mm (6 ).
