When it's time to change your roofing system, the amount of information readily available can be frustrating. Great deals of sites and videos enter into fantastic detail on how to shingle a roof. This post from the experts at IKO Roofing will assist you make sense of all of it by highlighting the standard actions and describing the fundamental function for each roof system component.
The next time you check out the package directions or enjoy a how-to video on YouTube, you'll have a better understanding of why roof shingles are installed the method they are. Operating at heights on a roof presents fall hazard threats and other safety concerns. IKO suggests that roofing work be done by certified experts who know the best way to shingle a roofing system and have been totally trained in all elements of roof construction safety.
Asphalt roof shingles just depend on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing parts are arranged and overlapped with this in mind, the roof must successfully shed water. In the dictionary, "to shingle" is defined as "to lay out or organize so regarding overlap." So now let's look at the series of overlapping roofing system building parts to see how this applies.
Having a clean, flat deck surface area will assist ensure that the freshly shingled roofing will likewise appear smooth and flat when ended up. Not just are we working from the bottom of the roofing system, we're also starting with the bottom-most layer, in regards to roofing parts - replacing shingles. The asphalt roof shingles are the visible part and the first line of defense versus inclement weather, but what's underneath them really counts.
It actually offers a tidy, sharp edge for the start of the roofing and safeguards the lower edge of the roofing system deck from water damage by preventing water from "defying gravity" and wicking back "up" prior to it leaves the roofing system. 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 component and it gets set up over the drip edge. Ice dam formation is best avoided by having an appropriate attic vapor barrier, appropriate attic insulation and extensive ventilation; nevertheless, an ice defense membrane is a sensible roof element and is likely needed by your regional structure code in cold environments.
To be fully reliable, it should 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 need to likewise be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes deal with the concept that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding protection.
Both provide you peace-of-mind protection underneath the shingles. While the asphalt shingles will be the main water-shedding roof layer, there are numerous advantages to installing a roof 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? When going up the sloped edges of the roofing system (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 creates a clean roofing edge and provides the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment offers your roofing system secondary layer of defense. asphalt roof shingles. If a roofing system is going to leakage, it will more than likely occur wherever the shingle layer is permeated, disrupted or fulfills a wall. These are the unique areas that require flashing an included layer of water-shedding product to assist keep the water running downslope.
If your roof 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 installation. For longer roofing efficiency, IKO highly suggests open metal valleys. Complete the application of underlayment and valley flashing before the roof 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 temporarily along one edge. Carefully peel away the backing, and put it in location, raveling any wrinkles. Start working from the eave, allowing extra pieces to overlap by a minimum of 150 mm (6 ).
