When it's time to change your roofing system, the amount of information offered can be frustrating. Lots of sites and videos go into great information on how to shingle a roof. This article from the professionals at IKO Roofing will help you make sense of everything by highlighting the standard steps and laying out the essential purpose for each roof element.
The next time you read the package directions or watch a how-to video on YouTube, you'll have a better understanding of why roof shingles are set up the way they are. Operating at heights on a roofing system provides fall threat dangers and other safety issues. IKO recommends that roofing work be done by qualified specialists who know the very best way to shingle a roofing and have actually been completely trained in all elements of roofing building and construction security.
Asphalt roof shingles just depend on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing system parts are arranged and overlapped with this in mind, the roof ought to successfully shed water. In the dictionary, "to shingle" is defined as "to set out or set up so regarding overlap." So now let's look at the series of overlapping roofing system construction parts to see how this uses.
Having a clean, flat deck surface area will assist make sure that the newly shingled roofing system will similarly appear smooth and flat when finished. Not only are we working from the bottom of the roof, we're likewise beginning with the bottom-most layer, in terms of roof elements - house shingles. The asphalt roofing shingles are the noticeable part and the very first line of defense against severe weather condition, however what's beneath them really 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 avoiding water from "levitating" and wicking back "up" before it leaves the roof. 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 best avoided by having a proper attic vapor barrier, adequate attic insulation and thorough ventilation; nevertheless, an ice protection membrane is a wise roofing system element and is most likely needed by your local building regulations in cold climates.
To be fully efficient, it must extend up the roofing 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 also be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes deal with the principle that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding protection.
Both offer you peace-of-mind security below the shingles. While the asphalt shingles will be the primary water-shedding roofing system layer, there are many benefits to installing 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 roof (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping concept, setting up the drip edge over the underlayment at the rakes produces a tidy roof edge and offers the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment gives your roof secondary layer of security. replacing shingles. If a roofing system is going to leakage, it will most likely take place wherever the shingle layer is permeated, interrupted or satisfies a wall. These are the special areas that require flashing an included layer of water-shedding product to assist keep the water running downslope.
If your roofing system will have open valleys, which IKO suggests, now is when the valleys ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished during shingle installation. For longer roof efficiency, IKO highly recommends 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 location momentarily along one edge. Carefully peel away the backing, and put it in place, raveling any wrinkles. Start working from the eave, allowing additional pieces to overlap by a minimum of 150 mm (6 ).
