When it's time to change your roofing system, the amount of details available can be overwhelming. Lots of sites and videos enter into excellent information on how to shingle a roofing system. This article from the specialists at IKO Roofing will help you understand all of it by highlighting the fundamental actions and laying out the basic function for each roof part.
The next time you check out the package instructions or see 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 roofing presents fall hazard threats and other security issues. IKO suggests that roof work be done by certified professionals who understand the very best method to shingle a roofing system and have been fully trained in all aspects of roof building and construction safety.
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 roofing system parts are set up and overlapped with this in mind, the roof needs to successfully shed water. In the dictionary, "to shingle" is specified as "to lay out or arrange so regarding overlap." So now let's look at the series of overlapping roofing building parts to see how this uses.
Having a clean, flat deck surface will assist guarantee that the newly shingled roofing system will similarly appear smooth and flat when ended up. Not only are we working from the bottom of the roofing, we're also starting with the bottom-most layer, in regards to roof components - replacing shingles. The asphalt roofing system shingles are the noticeable part and the first line of defense versus inclement weather condition, however what's below them really counts.
It actually offers a tidy, sharp edge for the start of the roofing and safeguards the lower edge of the roofing deck from water damage by preventing water from "levitating" and wicking back "up" prior to it leaves the roofing. 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 component and it gets installed over the drip edge. Ice dam formation is finest prevented by having an appropriate attic vapor barrier, sufficient attic insulation and comprehensive ventilation; nevertheless, an ice security membrane is a wise roof system part and is most likely needed by your local building code in cold climates.
To be totally reliable, it must 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 must 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 covering seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding security.
Both offer you peace-of-mind security beneath the shingles. While the asphalt shingles will be the primary water-shedding roof 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.
Bear in mind that drip edge we set up at the bottom of the roofing system? When increasing the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this appears to oppose the overlapping principle, installing the drip edge over the underlayment at the rakes creates a tidy roofing edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing Underlayment offers your roof secondary layer of protection. asphalt roof shingles. If a roof is going to leakage, it will most likely happen anywhere the shingle layer is penetrated, disturbed or satisfies a wall. These are the unique areas that require flashing an added layer of water-shedding product to assist keep the water running downslope.
If your roof will have open valleys, which IKO suggests, now is when the valleys need to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished during shingle installation. For longer roofing system performance, IKO highly recommends open metal valleys. Total 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 briefly along one edge. Thoroughly peel away the support, and put it in location, smoothing out any wrinkles. Start working from the eave, permitting extra pieces to overlap by a minimum of 150 mm (6 ).
