When it's time to replace your roofing, the amount of info available can be overwhelming. Great deals of sites and videos enter into great detail on how to shingle a roofing. This post from the specialists at IKO Roofing will help you make sense of all of it by highlighting the fundamental actions and describing the fundamental function for each roof element.
The next time you read the plan directions or view a how-to video on YouTube, you'll have a better understanding of why roof shingles are installed the way they are. Operating at heights on a roofing presents fall danger risks and other security concerns. IKO advises that roof work be done by certified professionals who understand the finest method to shingle a roof and have actually been completely trained in all aspects of roof building safety.
Asphalt roof shingles merely count on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing system parts are arranged and overlapped with this in mind, the roofing must successfully shed water. In the dictionary, "to shingle" is defined as "to lay out or arrange so regarding overlap." So now let's take a look at the series of overlapping roofing building elements to see how this uses.
Having a tidy, flat deck surface area will help make sure that the newly shingled roofing will likewise appear smooth and flat when ended up. Not only are we working from the bottom of the roofing, we're likewise starting with the bottom-most layer, in terms of roofing parts - asphalt roof shingles. The asphalt roofing system shingles are the visible part and the very first line of defense versus severe weather condition, however what's beneath them actually counts.
It actually offers a tidy, sharp edge for the start of the roofing system and safeguards the lower edge of the roofing system deck from water damage by avoiding water from "levitating" and wicking back "up" prior to it leaves the roofing. 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 component and it gets set up over the drip edge. Ice dam formation is finest prevented by having an appropriate attic vapor barrier, appropriate attic insulation and thorough ventilation; however, an ice protection membrane is a smart roofing system element and is most likely needed by your local building code in cold environments.
To be completely reliable, it must 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 also 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 finish seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding protection.
Both use you peace-of-mind protection below the shingles. While the asphalt shingles will be the primary water-shedding roofing system layer, there are lots of advantages 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 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, setting up the drip edge over the underlayment at the rakes creates a tidy roofing edge and provides the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment provides your roofing secondary layer of security. installing shingles. If a roof is going to leak, it will probably occur anywhere the shingle layer is penetrated, disrupted or satisfies a wall. These are the special areas that require flashing an added layer of water-shedding material to assist keep the water running downslope.
If your roofing system will have open valleys, which IKO suggests, now is when the valleys must be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle installation. For longer roofing system performance, IKO highly advises open metal valleys. Complete 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 item is added in location momentarily along one edge. Carefully peel away the support, and put it in location, smoothing out any wrinkles. Start working from the eave, enabling extra pieces to overlap by a minimum of 150 mm (6 ).
