When it's time to replace your roof, the quantity of information readily available can be overwhelming. Great deals of websites and videos go into great detail on how to shingle a roofing system. This short article from the professionals at IKO Roofing will help you understand everything by highlighting the basic actions and outlining the basic function for each roof system element.
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 roof shingles are installed the way they are. Operating at heights on a roofing presents fall risk threats and other safety issues. IKO advises that roofing work be done by qualified experts who know the best method to shingle a roofing system and have actually been completely trained in all aspects of roof construction security.
Asphalt roofing shingles just count on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roof elements are arranged 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 series of overlapping roofing construction elements to see how this applies.
Having a clean, flat deck surface area will assist make sure that the newly shingled roofing system will similarly appear smooth and flat when completed. Not just are we working from the bottom of the roof, we're likewise starting with the bottom-most layer, in regards to roof elements - replacing shingles. The asphalt roofing system shingles are the noticeable part and the first line of defense versus inclement weather condition, however what's beneath them truly counts.
It literally supplies a tidy, sharp edge for the start of the roof and secures the lower edge of the roofing deck from water damage by avoiding water from "defying gravity" 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 installed over the drip edge. Ice dam development is best prevented by having a correct attic vapor barrier, adequate attic insulation and extensive ventilation; nevertheless, an ice security membrane is a sensible roof system part and is likely required by your local building code in cold environments.
To be totally efficient, it needs 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 need to likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes work on the principle that their rubberized asphalt covering seals around the shanks of the overlying shingle fasteners, including an extra degree of water-shedding security.
Both offer you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are numerous 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.
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 seems to oppose the overlapping principle, setting up the drip edge over the underlayment at the rakes produces a clean roof edge and provides the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment gives your roof secondary layer of defense. replacing shingles. If a roof is going to leakage, it will more than likely happen any place the shingle layer is penetrated, cut off or fulfills a wall. These are the unique locations that require flashing an added layer of water-shedding product to help keep the water running downslope.
If your roofing system will have open valleys, which IKO recommends, now is when the valleys should be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle installation. For longer roofing system performance, IKO strongly recommends open metal valleys. Total the application of underlayment and valley flashing prior to the roof shingles are applied.
Center a 914 mm (36) width strip of an ice and water protector membrane in the valley. The product is tacked in place momentarily along one edge. Carefully peel away the backing, and put it in location, raveling any wrinkles. Start working from the eave, enabling extra pieces to overlap by at least 150 mm (6 ).
