When it's time to change your roofing, the amount of details readily available can be frustrating. Lots of websites and videos go into fantastic detail on how to shingle a roofing system. This short article from the specialists at IKO Roofing will help you make sense of everything by highlighting the fundamental actions and laying out the basic function 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 roofing shingles are set up the way they are. Operating at heights on a roofing provides fall risk risks and other security concerns. IKO recommends that roof work be done by qualified specialists who understand the very best way to shingle a roof and have been fully trained in all aspects of roofing system building security.
Asphalt roof shingles merely depend on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roof parts are organized 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 organize so regarding overlap." So now let's take a look at the sequence of overlapping roofing building elements to see how this applies.
Having a clean, flat deck surface will assist make sure that the newly shingled roof will similarly appear smooth and flat when completed. Not only are we working from the bottom of the roofing system, we're likewise starting with the bottom-most layer, in terms of roof parts - house shingles. The asphalt roofing shingles are the visible part and the very first line of defense versus severe weather, however what's underneath them really counts.
It actually offers a tidy, sharp edge for the start of the roofing system and protects the lower edge of the roofing system deck from water damage by preventing water from "defying gravity" and wicking back "up" before it leaves the roofing. Drip 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 element and it gets installed over the drip edge. Ice dam development is best avoided by having a correct attic vapor barrier, sufficient attic insulation and extensive ventilation; however, an ice security membrane is a sensible roof component and is most likely required by your local building regulations in cold environments.
To be totally effective, it ought to extend up the roofing system 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 system should likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes deal with the principle that their rubberized asphalt finishing seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding security.
Both offer you peace-of-mind security underneath the shingles. While the asphalt shingles will be the main water-shedding roofing system layer, there are lots of advantages 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.
Remember that drip edge we set up at the bottom of the roof? When going up the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping concept, installing the drip edge over the underlayment at the rakes produces a clean roofing system edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment provides your roofing secondary layer of protection. asphalt roof shingles. If a roof is going to leak, it will probably happen wherever the shingle layer is penetrated, disturbed or fulfills a wall. These are the special areas that need flashing an added layer of water-shedding material to assist keep the water running downslope.
If your roofing will have open valleys, which IKO advises, now is when the valleys need to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle setup. For longer roof efficiency, IKO highly suggests open metal valleys. Complete the application of underlayment and valley flashing before 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 added in place briefly 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 ).
