When it's time to change your roofing, the amount of details offered can be overwhelming. Lots of sites and videos enter into excellent detail on how to shingle a roof. This short article from the professionals at IKO Roofing will help you make sense of everything by highlighting the basic steps and detailing the essential purpose for each roof system component.
The next time you check out the package guidelines or view a how-to video on YouTube, you'll have a far better understanding of why roof shingles are installed the method they are. Working at heights on a roofing system provides fall hazard threats and other security concerns. IKO advises that roofing work be done by qualified specialists who know the very best way to shingle a roof and have actually been completely trained in all aspects of roofing system building safety.
Asphalt roof shingles simply depend on the force of gravity to shed water from rain or snow melt. If the roof shingles and all accessory roofing parts are organized and overlapped with this in mind, the roofing system should successfully shed water. In the dictionary, "to shingle" is specified as "to lay out or organize so regarding overlap." So now let's take a look at the sequence of overlapping roofing system construction parts to see how this uses.
Having a clean, flat deck surface area will help make sure that the recently shingled roofing will similarly appear smooth and flat when finished. Not just are we working from the bottom of the roofing system, we're also starting with the bottom-most layer, in regards to roof components - replacing shingles. The asphalt roofing shingles are the noticeable part and the first line of defense against severe weather, however what's beneath them actually counts.
It literally 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 "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 element and it gets set up over the drip edge. Ice dam development is best avoided by having a correct attic vapor barrier, appropriate attic insulation and thorough ventilation; nevertheless, an ice defense membrane is a sensible roof system element and is likely needed by your regional building regulations in cold environments.
To be totally effective, it must 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 roofing should likewise be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes work on the principle that their rubberized asphalt finish seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding security.
Both provide you peace-of-mind protection underneath the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are lots of 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 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 creates a tidy roofing system edge and supplies the underlayment accessory with increased resistance versus wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment gives your roof secondary layer of security. house shingles. If a roofing system is going to leak, it will more than likely take place wherever the shingle layer is penetrated, interrupted or satisfies a wall. These are the special areas that require flashing an added layer of water-shedding material to help keep the water running downslope.
If your roof will have open valleys, which IKO recommends, now is when the valleys ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are completed throughout shingle installation. For longer roofing performance, IKO highly recommends open metal valleys. Total the application of underlayment and valley flashing prior to 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 backing, and put it in place, smoothing out any wrinkles. Start working from the eave, permitting additional pieces to overlap by at least 150 mm (6 ).
