When information technology'south time to replace your roof, the amount of data available can exist overwhelming. Lots of websites and videos become into keen particular on how to shingle a roof. This article from the experts at IKO Covering will aid you lot make sense of it all by highlighting the bones steps and outlining the primal purpose for each covering system component. This article is non a substitute for proper alive preparation and IKO recommends that merely properly trained professional person covering contractors appoint in the shingling of roofs.

The next time you read the package instructions or sentinel a how-to video on YouTube, y'all'll have a much better agreement of why roof shingles are installed the style they are.

Here are the basic steps to shingle a roof.

i. Pace one in whatsoever roofing project is ever rubber first. Working at heights on a roof presents fall hazard risks and other safety concerns. IKO recommends that roofing piece of work exist washed by qualified professionals who know the best way to shingle a roof and accept been fully trained in all aspects of roof structure safety. Further, information technology'south important to review local applicative edifice codes and ensure the roof conforms to all requirements.

2. Understand the physics of how a sloped shingle roof works. Cobblestone roofing shingles simply rely on the strength of gravity to shed h2o from rain or snow melt. If the roof shingles and all accessory roof components are arranged and overlapped with this in mind, the roof should successfully shed water. In the dictionary, "to shingle" is defined every bit "to lay out or arrange so as to overlap." And so now let'southward look at the sequence of overlapping roof construction components to come across how this applies.

3. Deck training. Before installing whatsoever roofing materials, make certain that the roof deck is smooth, properly attached to the roof trusses, dry out and free of whatsoever gaps or holes. Having a make clean, flat deck surface volition help ensure that the newly shingled roof will likewise appear shine and apartment when finished.

4. Piece of work from the bottom upwards. Non just are we working from the bottom of the roof, we're likewise starting with the bottom-most layer, in terms of roofing components. The asphalt roof shingles are the visible role and the first line of defense against inclement weather, simply what's underneath them really counts.The outset material installed at the eave is the drip edge. Information technology literally provides a make clean, precipitous edge for the get-go of the roof and protects the lower border of the roof deck from water damage by preventing water from "defying gravity" and wicking back "up" earlier it leaves the roof.

Baste edge is installed under the ice and water at the eaves and on top of the ice and water and underlayment on the rakes.

five. Water ice dam protection at the eaves. If you live in an surface area where the climate includes significant cold winter weather, you'd article of clothing boots to protect your feet from ice, slush and puddles, right? Well, your roof and the dwelling house under it demand the same kind of protection that an ice and water protector is engineered to provide. This thin, cocky-adhering membrane is the next component and it gets installed over the drip border. Water ice dam germination is best prevented by having a proper attic vapor bulwark, adequate cranium insulation and thorough ventilation; all the same, an ice protection membrane is a wise roofing system component and is likely required by your local building code in cold climates. This water ice and h2o membrane is typically practical to overhang the eaves past ane/4″-three/4″. To be fully effective, it should extend upwards the roof to a betoken at to the lowest degree 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 work on the principle that their rubberized asphalt coating seals around the shanks of the overlying shingle fasteners, adding an extra degree of water-shedding protection.

Ice dams form when melted snow runs downwards the roof to the eaves and freezes again, which forces water back upward underneath the shingles.

6. Underlayment for overall secondary roof protection. Adjacent it's time for the roof underlayment, which can either be an asphalt-saturated felt or a synthetic roof underlayment. Both offer you peace-of-listen protection beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, at that place are many benefits to installing a roof underlayment. The felt is laid in horizontal courses, overlapping the eave water ice and water protector by 4″ and the valley membrane flashing by 6″. Annotation: If your home is in a region where water ice and water protector is not required, kickoff the underlayment installation at the eave, overhanging the baste edge by ane/4″- 3/4″. Remember that drip border we installed at the bottom of the roof? When going up the sloped edges of the roof (called the "rakes") information technology goes on top of the underlayment. Although this seems to contradict the overlapping principle, installing the drip edge over the underlayment at the rakes creates a clean roof edge and provides the underlayment attachment with increased resistance against current of air uplift. Also, whatsoever wind-driven pelting blowing on the rake border would cross the top flange of the baste edge and become on meridian of the underlayment instead of beneath the underlayment where information technology could potentially cause a problem.

seven. Covering the joints and valleys. If a roof is going to leak, it will most likely occur wherever the shingle layer is penetrated, interrupted or meets a wall. These are the special areas that require flashing – an added layer of water-shedding material to assist keep the water running downslope. Valleys tin either be open up or closed – open valleys are not covered with shingles, closed valleys are. If your roof will have open valleys, which IKO recommends, now is when the valleys should be lined with a pre-formed width of corrosion-resistant metallic. Closed valleys are completed during shingle installation. For longer roof operation, IKO strongly recommends open metal valleys. Consummate the awarding of underlayment and valley flashing earlier the roofing shingles are applied. The recommended flashing fabric is a 28-gauge galvanized metal or an equivalent corrosion resistant, non-staining fabric (check with local codes). Middle a 914 mm (36″) width strip of an water ice and h2o protector membrane in the valley. The production is tacked in place temporarily forth one edge. Carefully peel away the backing, and put it in place, smoothing out any wrinkles. Start working from the eave, allowing additional pieces to overlap past at least 150 mm (half dozen″). Remove the temporary nails. Center a minimum 610 mm (24″) wide, minimum 28 estimate pre-finished/galvanized metal valley liner in the valley, and fasten with merely enough nails to hold it in identify, nailing at the edges only. Overlap each metal piece past at least 150 mm (6″) and use asphalt plastic cement nether each department of overlap. Snap two chalk lines the full length of the valley, 150 mm (six″) apart at the top 75 mm (iii″) on each side of the valley and increasing in width three mm (1/8″) per 300 mm (12″) towards the bottom to a maximum of 200 mm (8″). When the shingles are being applied, lay them over the valley flashing, trim the ends to the chalk line and nail the shingles at least 50 mm (2″) dorsum from the chalk line. Cut a 50 mm (2″) triangle off the peak corner to direct water into the valley and embed the valley end of each shingle into a 75 mm (3″) ring of cobblestone plastic cement. It's critical to flash around plumbing stacks and attic vents because they are the most mutual roof penetrations. Install metal flashings where shingles see walls or chimneys, as well. Ice and water protector membranes work well to flash and help protect around skylights, dormers, turbines and other tricky roof areas. Utilise flashing materials in concert with the shingle installation procedure, with both the flashing and the shingles arranged to work together to protect around the articulation areas.

Various Roof Vents

Roof planes that butt against vertical walls at the end of the shingle course are protected by metallic step flashing at least 125 mm high and 125 mm wide (5″ high and v″ broad). When applying the new shingles, each shingle course will exist covered past a step flashing.

Metallic Step Flashing Pieces

There are ii simple rules to follow:

• Each flashing should overlap the one below by at to the lowest degree 75 mm (3″), but non exist visible below the shingle top lap.
• Imbed each footstep flashing in a 75 mm (3″) wide awarding of asphaltic plastic cement, and blast in place. Then the end of each shingle overlapping a stride flashing must also be well embedded in plastic cement.

The metal step flashing pieces are rectangular in shape and mode, approximately 250 mm (10″) long and at least 50 mm (2″) wider than the face of the shingle being used. For instance, when using metal flashing with shingles with a typical 143 mm (5 5/viii″) exposure (such every bit traditional 3-tab shingles), the size of the flashing will exist 250 mm x 200 mm (ten″ 10 eight″). The 250 mm (10″) length is bent in half so that 125 mm (five″) volition attain up the wall surface and the other 125 mm (v″) will extend onto the roof deck. Annotation: Other step flashing sizes are also acceptable. For IKO'due south Cambridge shingle, with its larger 5 7/8″ exposure, a 10″ x 8″ flashing piece is nevertheless suitable, since the eight″ dimension is still at least 2″ larger than the shingle'southward exposure dimension. However, when flashing Crowne Slate, with its much larger 10″ exposure, the flashing piece would demand to exist 10″ 10 12″.

To install the flashing slice on the first class, place information technology over the finish of the starter strip. Place information technology so the tab of the end shingle covers it completely. Secure the horizontal flange to the roof deck using two nails. Do not fasten the flashing slice to the vertical wall. This will allow the flashing piece to movement independently of whatsoever differential expansion and contraction that may occur between the roof deck and the wall. Place the 2d step flashing piece over the end shingle in the first class by positioning it 143 mm (v five/8″) above the bottom edge of the exposed asphalt shingle.

Make sure that the tab of the shingle in the 2d course will cover information technology completely. Secure the horizontal flange to the roof. The second and succeeding courses will follow with the end shingles flashed as in preceding courses.

viii. The shingles in the "field" of the roof. One time everything that goes beneath the shingles has been properly prepared and installed, it's finally fourth dimension to learn how to shingle a roof. Regardless of the asphalt shingle type or style you lot've chosen, the process is basically the same equally mentioned before – you start at the bottom and overlap as you lot piece of work your way across and up the roof. First – earlier you lay the field shingles ("field" referring to the large expanse of roof within the boundaries of eaves, ridge and rakes) – it's important to install a preparatory course of starter shingles which are specifically manufactured for that purpose. But, even if y'all fashion your own on-site past cutting standard shingles to size, both serve critical functions at the roof's eave. They provide a sealant adhesion signal for the first grade of shingles and provide water-shedding protection at shingle joints also as at any cut-outs. Professional contractors ofttimes recommend and use starter strips along rake edges in social club to yield a straight edge from which all the field courses can brainstorm. Furthermore, these starter strips raise the roof arrangement'southward wind-resistance at the rake. Information technology's critical to follow the manufacturer'south instructions for the specific roof shingle because not all shingles have the same exposure (the function of the shingle that'south visible once installed), offset (the lateral distance between joints in successive courses sometimes called 'stagger' or 'border-to-edge spacing') and/or nail placement. Issues may occur if the shingles are given also much exposure or too little or if they're not offset by the proper dimension in successive courses (rows of shingles). You must place nails in the proper location and drive them flush with, simply non cutting into, the shingle. Nailing the shingles correctly is disquisitional to the roof arrangement'due south air current-resistance. Proper nail placement is also a requirement for the shingles' express warranty coverage. If you've chosen closed valleys, they are completed as shingle courses approach and run through the valley. The nigh common closed valley is a "closed cut" valley, where shingles are installed on the entire roof area on ane side of the valley commencement, with each shingle course extending at to the lowest degree 12″ through the valley centerline. As shingles are installed on the adjoining roof area, the stop of each course of shingles is trimmed (cut) 2″ back of the valley centerline.

9. The hip and ridge caps. You've nailed in the last field shingle and you tin encounter the finish line from here. Well done! In this case, the terminate line is the hip and ridge capping. When you install the field shingles upwards to the peak of the roof, you lot can't just "bend them" over the peak. Instead, private ridge cap shingles are used to straddle the ridge and shed water down either slope. There are various ridge cap shingles bachelor on the market place but, once more, the procedure for installing them is based on the same fundamental principle of overlapping. For hips, start at the bottom and work upslope. Since ridges are on a horizontal aeroplane, the upslope principle doesn't apply, so ridge cap shingles are typically installed similar this: begin at the end of the ridge opposite the prevailing wind direction, for optimum ridge cap wind-resistance. On hip roofs, it's also adequate to install the ridge caps starting at each end of the ridge, with the last piece installed in the center of the ridge. The last ridge cap piece should be nailed in place and, since this will exist the only identify on the roof where the nails are directly exposed, the smash heads should exist sealed and covered with a suitable asphalt roof cement. Always remember to use longer nails for ridge cap shingles. Because the nails must penetrate the ridge caps and the last grade of roof shingles below, you'll need longer nails to fully penetrate through them to the roof deck.
