Who to install roof
Closed valleys are completed during shingle installation. For longer roof performance, IKO strongly recommends open metal valleys. Complete the application of underlayment and valley flashing before the roofing shingles are applied.
The recommended flashing material is a gauge galvanized metal or an equivalent corrosion resistant, non-staining material check with local codes. The product is tacked in place temporarily along one edge. Carefully peel away the backing, and put it in place, smoothing out any wrinkles. Remove the temporary nails. Install metal flashings where shingles meet walls or chimneys , too.
Ice and water protector membranes work well to flash and help protect around skylights, dormers , turbines and other tricky roof areas. Apply flashing materials in concert with the shingle installation procedure , with both the flashing and the shingles arranged to work together to protect around the joint areas. When applying the new shingles, each shingle course will be covered by a step flashing.
Metal Step Flashing Pieces. Note: Other step flashing sizes are also acceptable. To install the flashing piece on the first course, place it over the end of the starter strip. Place it 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 piece to the vertical wall. This will allow the flashing piece to move independently of any differential expansion and contraction that may occur between the roof deck and the wall.
Make sure that the tab of the shingle in the second course will cover it completely. Secure the horizontal flange to the roof.
The second and succeeding courses will follow with the end shingles flashed as in preceding courses. They provide a sealant adhesion point for the first course of shingles and provide water-shedding protection at shingle joints as well as at any cut-outs. Drive a roofing nail through the flat portion of the shingle at the top, and install a single row around the entire roof. These shingles are slightly easier to install since they fold together really cleanly, but you do need to use the starter shingle first.
Work your way up in rows to lay your shingles on top of one another. Repeat the chalk line process with your second row. Lay the first shingle down so that the bottom 5 inches 13 cm are laying over the top of your first row.
This pyramid-style layering is the safest way to protect the shingles and the roof from water. If your shingles are bigger than the traditional asphalt shingles, just try to split the difference when it comes to how much overlap there is between the columns. Cover the rest of the roof and install flashing around pipes and edges. Keep repeating this process by adding additional layers. Then, measure, cut, and bend the flashing for your chimney.
Install the flashing by laying it over the edge and around the pipes, and nail it into place. Lay exterior silicone caulk around the seams to protect them from water. Method 3. Install your drip trim if the roof has no overhang. Lay the strips of drip trim along the edge of the roof where your roof ends and use a nail gun or nail and hammer to adhere it to the roof. Lay your membrane sheets out and let them sit for 20 minutes.
Bring your sheets up to the roof. These things come in giant rolls, so remove the wrapping and lay them out. Wait at least 20 minutes for the membrane sheets to relax. This will give them time to adjust to the environment, which is essential if you want to avoid wrinkles, stretches, or sags.
This can reduce the level of protection over time. There should be at least 3—5 inches 7. Smooth it out by hand with a roller. Cut the rubber as needed with a utility knife to fit corners.
If your roof has any odd angles or you run into chimneys or odd edges, cut the membrane sheets with a utility knife or scissors. Air on the side of caution and always leave a little extra material to totally cover the flat portion of the roof.
Mix and apply the manufacturer-recommended adhesive. Follow the instructions to mix the EPDM adhesive in the container. Usually, you just mix it with a mixing stick. Wait a few minutes for the adhesive to cure a bit. Smooth out the first half of the sheet. Once the adhesive is tacky, slowly and carefully spread the sheet over the adhesive so the two surfaces are touching.
Smooth it out with your hand while you work to remove any air bubbles. Once the first half is in place, use a roller to smooth out the membrane and make it flat and uniform.
Repeat this process on the other half of the membrane sheet. Peel back the other half of the sheet and repeat this process by applying the adhesive on both the underside of the sheet, and the roof itself. Smooth it out by hand and run a roller over the surface to smooth it out.
If you have a skylight or several skylights on your roof, they will almost certainly require flanging around the edges to prevent rainwater from seeping into them. Skylights are generally shipped with the necessary flashing, but if it's not there, roofers will install it themselves to ensure a tight seal. When the roof and a wall meet, flashing is used. It's similar to continuous flashing, but it's made up of a rectangular piece of flashing that descends the roof and appears to go up the walls as it goes.
Step flashing may be used for a variety of reasons. They are necessary to offer that safety net in addition to any roof-ceiling combination. It might be a third-story or dormer window situation that needs step flashing. Flashing is required on any open area of the roof. Valley flashing will reside in the valley crevasse, ensuring that the joint between the two roofs is securely sealed against leaks.
You may choose from various colors and styles to match your shingles. The procedure for installing roof flashing depends on the flashing chosen for a specific job. Although the steps are varied, the fundamentals remain consistent. We'll concentrate on the step and kick-out flashing because they're among the most popular forms of flashing. The roofing underlayment is a substance that serves as an additional layer of protection for your roof. This must be placed beneath your shingles and on top of your underlayment.
If you have a shingled roof, this implies you'll need to remove the shingles to install the underlayment and to flash. To install kick-out flashing, you must first secure it to the roof's foundation and both the wall and the bottom of the top. Then you may begin working your way up. Once the underlayment and flashing have been installed, you must install the first shingle to keep it in place. Secure the shingle over the flashing base with nails and roofing cement for a solid seal. Specify Project Size and Options Enter the number of "square feet" required for the project.
