When it's time to change your roof, the quantity of details available can be frustrating. Lots of websites and videos enter into fantastic detail on how to shingle a roofing. This article from the specialists at IKO Roof will assist you make sense of it all by highlighting the basic steps and describing the basic purpose for each roofing system part.
The next time you check out the bundle guidelines or watch a how-to video on YouTube, you'll have a far better understanding of why roofing system shingles are installed the way they are. Operating at heights on a roofing presents fall danger risks and other security concerns. IKO recommends that roof work be done by qualified professionals who know the best method to shingle a roof and have actually been fully trained in all elements of roof construction security.
Asphalt roof shingles just count on the force of gravity to shed water from rain or snow melt. If the roofing system shingles and all accessory roofing parts are organized and overlapped with this in mind, the roofing must successfully shed water. In the dictionary, "to shingle" is defined as "to set out or arrange so regarding overlap." So now let's take a look at the series of overlapping roofing system building and construction elements to see how this uses.
Having a clean, flat deck surface will assist ensure that the recently shingled roofing system will similarly appear smooth and flat when completed. Not just are we working from the bottom of the roofing system, we're likewise starting with the bottom-most layer, in regards to roofing components - replacing shingles. The asphalt roof shingles are the visible part and the first line of defense versus inclement weather, however what's underneath them truly counts.
It actually provides a clean, sharp edge for the start of the roofing system and secures the lower edge of the roofing deck from water damage by avoiding water from "defying gravity" and wicking back "up" before it leaves the roof. Drip 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 part and it gets installed over the drip edge. Ice dam formation is finest avoided by having a correct attic vapor barrier, appropriate attic insulation and comprehensive ventilation; nevertheless, an ice security membrane is a smart roof element and is likely required by your local building regulations in cold environments.
To be totally reliable, 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 roof should likewise be flashed with an ice and water membrane. Why an ice and water protector? Because these membranes deal with the principle that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, adding an additional degree of water-shedding security.
Both offer you peace-of-mind defense beneath the shingles. While the asphalt shingles will be the main water-shedding roofing system layer, there are lots of benefits 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.
Remember that drip edge we installed at the bottom of the roofing system? When increasing the sloped edges of the roofing (called the "rakes") it goes on top of the underlayment. Although this appears to contradict the overlapping concept, setting up the drip edge over the underlayment at the rakes develops a tidy roofing edge and supplies the underlayment accessory with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roofing system Underlayment gives your roofing system secondary layer of security. installing shingles. If a roofing system is going to leak, it will most likely occur anywhere the shingle layer is permeated, disrupted or satisfies a wall. These are the special areas that need flashing an included 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 ought to be lined with a pre-formed width of corrosion-resistant metal. Closed valleys are finished throughout shingle setup. For longer roofing 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 product is added in place temporarily along one edge. Thoroughly peel away the backing, and put it in location, smoothing out any wrinkles. Start working from the eave, allowing additional pieces to overlap by a minimum of 150 mm (6 ).
