When it's time to change your roof, the amount of information offered can be overwhelming. Lots of websites and videos enter into excellent information on how to shingle a roof. This short article from the specialists at IKO Roofing will help you make sense of it all by highlighting the basic steps and detailing the essential function for each roof element.
The next time you check out the plan directions or see a how-to video on YouTube, you'll have a much better understanding of why roof shingles are set up the way they are. Working at heights on a roofing system provides fall danger threats and other security issues. IKO advises that roof work be done by certified experts who understand the very best method to shingle a roofing system and have been totally trained in all aspects of roof building and construction safety.
Asphalt roofing shingles merely count on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing system parts are set up and overlapped with this in mind, the roofing system should effectively shed water. In the dictionary, "to shingle" is defined as "to set out or organize so regarding overlap." So now let's look at the sequence of overlapping roof building and construction parts to see how this applies.
Having a tidy, flat deck surface will assist guarantee that the freshly shingled roofing will also appear smooth and flat when completed. Not only are we working from the bottom of the roofing system, we're likewise beginning with the bottom-most layer, in regards to roof components - replacing shingles. The asphalt roof shingles are the noticeable part and the very first line of defense against harsh weather, but what's beneath them really counts.
It literally provides a tidy, sharp edge for the start of the roofing and secures the lower edge of the roofing system deck from water damage by avoiding water from "defying gravity" and wicking back "up" before it leaves the roofing system. Drip 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 element and it gets installed over the drip edge. Ice dam formation is finest avoided by having a correct attic vapor barrier, sufficient attic insulation and extensive ventilation; nevertheless, an ice security membrane is a smart roof element and is most likely needed by your regional building regulations in cold climates.
To be totally reliable, it needs to extend up the roof 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 roof 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 covering seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding defense.
Both provide you peace-of-mind defense beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are numerous advantages 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 installed at the bottom of the roofing system? When increasing the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this seems to oppose the overlapping principle, installing the drip edge over the underlayment at the rakes produces a clean roof edge and offers the underlayment attachment with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment provides your roof secondary layer of security. replacing shingles. If a roof is going to leakage, it will probably occur wherever the shingle layer is penetrated, interrupted or satisfies a wall. These are the unique locations that require flashing an included layer of water-shedding material to assist keep the water running downslope.
If your roofing 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 completed during shingle setup. For longer roof efficiency, IKO highly suggests open metal valleys. Total the application of underlayment and valley flashing prior to the roofing shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The item is tacked in place briefly along one edge. Thoroughly peel away the backing, and put it in place, raveling any wrinkles. Start working from the eave, allowing additional pieces to overlap by at least 150 mm (6 ).
