The next time you check out the plan instructions or enjoy a how-to video on YouTube, you'll have a much better understanding of why roofing shingles are installed the method they are. Operating at heights on a roof presents fall danger threats and other safety issues. IKO recommends that roof work be done by certified professionals who know the very best method to shingle a roofing and have actually been fully trained in all elements of roof building security.
Asphalt roofing shingles just rely on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing system elements are arranged 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 regarding overlap." So now let's take a look at the series of overlapping roofing system construction parts to see how this applies.
Having a tidy, flat deck surface area will assist ensure that the recently shingled roof will also appear smooth and flat when ended up. Not only are we working from the bottom of the roofing system, we're likewise starting with the bottom-most layer, in regards to roof elements - house shingles. The asphalt roofing system shingles are the visible part and the very first line of defense against inclement weather condition, however what's beneath them really counts.
It literally offers a clean, sharp edge for the start of the roofing system and secures the lower edge of the roof deck from water damage by avoiding water from "defying gravity" and wicking back "up" prior to it leaves the roof. Leak edge is installed 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 installed over the drip edge. Ice dam development is best prevented by having an appropriate attic vapor barrier, sufficient attic insulation and extensive ventilation; however, an ice defense membrane is a smart roof part and is most likely needed by your regional structure code in cold environments.
To be totally efficient, it ought to 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 ought to also be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes work on the concept that their rubberized asphalt finishing seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding defense.
Both offer you peace-of-mind security below the shingles. While the asphalt shingles will be the primary water-shedding roofing layer, there are numerous benefits to setting up 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 installed at the bottom of the roofing system? When going up the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping principle, setting up the drip edge over the underlayment at the rakes develops a tidy roofing edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment provides your roofing secondary layer of protection. installing shingles. If a roofing system is going to leak, it will probably occur wherever the shingle layer is penetrated, interrupted or satisfies a wall. These are the special locations that need flashing an included layer of water-shedding product to assist keep the water running downslope.
If your roofing will have open valleys, which IKO recommends, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed during shingle installation. For longer roofing efficiency, IKO highly recommends open metal valleys. Total the application of underlayment and valley flashing prior to the roof 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 location temporarily along one edge. Carefully peel away the support, and put it in place, raveling any wrinkles. Start working from the eave, permitting extra pieces to overlap by a minimum of 150 mm (6 ).
