When it's time to replace your roofing, the amount of information available can be frustrating. Lots of sites and videos go into terrific detail on how to shingle a roofing system. This article from the experts at IKO Roofing will assist you make sense of it all by highlighting the standard actions and describing the essential function for each roof part.
The next time you read the bundle directions or view a how-to video on YouTube, you'll have a far better understanding of why roof shingles are set up the method they are. Operating at heights on a roof provides fall hazard risks and other security issues. IKO recommends that roof work be done by certified professionals who understand the very best method to shingle a roofing system and have actually been completely trained in all elements of roofing building and construction safety.
Asphalt roofing shingles simply depend on the force of gravity to shed water from rain or snow melt. If the roofing shingles and all accessory roofing components are organized and overlapped with this in mind, the roofing system should successfully shed water. In the dictionary, "to shingle" is defined as "to set out or arrange so regarding overlap." So now let's look at the sequence of overlapping roofing building and construction components to see how this uses.
Having a clean, flat deck surface will assist ensure that the newly shingled roof will likewise appear smooth and flat when finished. Not just are we working from the bottom of the roof, we're likewise starting with the bottom-most layer, in regards to roofing components - asphalt roof shingles. The asphalt roofing system shingles are the visible part and the first line of defense against severe weather condition, however what's below them truly counts.
It literally offers a clean, sharp edge for the start of the roofing and secures the lower edge of the roofing system deck from water damage by preventing water from "levitating" and wicking back "up" before it leaves the roofing system. 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 installed over the drip edge. Ice dam formation is finest avoided by having an appropriate attic vapor barrier, sufficient attic insulation and thorough ventilation; nevertheless, an ice defense membrane is a smart roof component and is likely required by your local building code in cold environments.
To be completely effective, it should extend up the roofing system 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 likewise be flashed with an ice and water membrane. Why an ice and water protector? Since these membranes work on the concept that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, including an additional degree of water-shedding protection.
Both provide you peace-of-mind security below the shingles. While the asphalt shingles will be the main water-shedding roofing system layer, there are numerous 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 set up at the bottom of the roofing system? When going up the sloped edges of the roofing system (called the "rakes") it goes on top of the underlayment. Although this seems to contradict the overlapping principle, installing the drip edge over the underlayment at the rakes develops a tidy roofing system edge and supplies the underlayment attachment with increased resistance against wind uplift.
IKO's RoofGard-Cool Grey Synthetic Roof Underlayment offers your roofing secondary layer of security. installing shingles. If a roof is going to leakage, it will more than likely happen wherever the shingle layer is penetrated, disrupted or satisfies a wall. These are the unique areas that require flashing an added layer of water-shedding material 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 completed throughout shingle installation. For longer roof performance, IKO strongly advises open metal valleys. Total the application of underlayment and valley flashing before the roofing 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. Carefully peel away the support, and put it in place, raveling any wrinkles. Start working from the eave, allowing additional pieces to overlap by at least 150 mm (6 ).
