When it's time to change your roofing, the amount of information readily available can be frustrating. Lots of websites and videos go into excellent information on how to shingle a roof. This short article from the specialists at IKO Roof will assist you understand it all by highlighting the fundamental actions and outlining the basic function for each roof component.
The next time you check out the bundle directions or see a how-to video on YouTube, you'll have a far better understanding of why roofing system shingles are set up the method they are. Operating at heights on a roofing system provides fall danger dangers and other security concerns. IKO recommends that roof work be done by qualified professionals who understand the best method to shingle a roof and have been totally trained in all aspects of roof building and construction safety.
Asphalt roofing shingles simply count on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing system components are arranged and overlapped with this in mind, the roofing needs to effectively shed water. In the dictionary, "to shingle" is defined as "to set out or arrange so regarding overlap." So now let's take a look at the series of overlapping roofing building and construction parts to see how this uses.
Having a tidy, flat deck surface area will assist make sure that the freshly shingled roofing system will similarly appear smooth and flat when completed. Not just are we working from the bottom of the roofing system, we're also starting with the bottom-most layer, in regards to roof components - replacing shingles. The asphalt roofing shingles are the noticeable part and the very first line of defense against severe weather condition, but what's beneath them actually counts.
It literally provides a tidy, 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 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 component and it gets set up over the drip edge. Ice dam formation is best prevented by having a correct attic vapor barrier, adequate attic insulation and comprehensive ventilation; nevertheless, an ice defense membrane is a smart roof system element and is likely needed by your local building regulations in cold environments.
To be totally effective, it should 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 roof must also 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, including an extra degree of water-shedding defense.
Both use you peace-of-mind security below the shingles. While the asphalt shingles will be the primary water-shedding roofing layer, there are many 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.
Keep in mind that drip edge we set up at the bottom of the roofing? 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 principle, installing the drip edge over the underlayment at the rakes creates a clean roofing system edge and provides the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment provides your roofing secondary layer of protection. installing shingles. If a roofing is going to leakage, it will more than likely take place any place the shingle layer is permeated, disrupted or satisfies a wall. These are the special locations that require flashing an included layer of water-shedding material to assist keep the water running downslope.
If your roof will have open valleys, which IKO suggests, now is when the valleys should be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed during shingle installation. For longer roofing system performance, IKO strongly recommends open metal valleys. Total 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 item is added in place momentarily along one edge. Carefully peel away the support, and put it in place, smoothing out any wrinkles. Start working from the eave, allowing additional pieces to overlap by a minimum of 150 mm (6 ).
