Be sure that these nails will hold the top edge of the course of shingles immediately below. Put a full shingle up against the cut shingle and nail into place. Repeat this basic pattern, alternating shingles across the roof, working toward the right side, using the chalk line to keep the shingles straight horizontally.
Use 4 nails per shingle and 6 nails on the prevailing windward sides of the roof, as wind resistance nailing. Some local codes require the 6 nails on all sides. Cut the last shingle to the size you need when you reach the end of the row. You can let the excess extend off the side end of the roof and trim it down after it is nailed on, if you like.
Continue this process to the 5th row then begin the same process as the first row beginning with a full shingle and a chalk mark. Repeat all of the way to the ridge. If it is a hip roof, allow about a tab width to overhang onto the next section of roof at the hip to help strengthen the joint there. Part 3. Install the last course. Bend the last course of shingles over the ridge, up to about 6 inches, and nail it onto the other side so that the roofing extends over the top of the ridge, where nails will be covered, leaving no exposed nails.
However, do not do this if a ridge vent system is being installed as well. Nearly all modern roofs use ridge venting — the sheeting stops short on each side. End your final shingle row here, using the hook-blade for cutting. To cover the ridge, install vented cap shingles or continuous ridge vent. Bend single tabs or special ridge shingles over the ridge, beginning at the end putting a bead of asphalt under the first ridge shingle to hold down the tab.
Nail it where the next ridge shingle will cover the nails about an inch horizontally and vertically. Install the ridge shingles. With the asphalt granules exposed, across to the other end, nail the shingles on both sides of the ridge as before.
Cut off the asphalt nail line from a ridge shingle when you get to the other end. Apply a heavy bead of asphalt cement. Dot the cement under and around the edge of the last ridge shingle where you removed the nail line. Nail at the four corners to the end of the ridge and add a little dab of tar to cover the nail heads. Also apply asphalt cement over the nail heads exposed on the last ridge shingle to prevent water leaks. Did you know you can get expert answers for this article?

Before you begin to install the asphalt shingles, spread the bundles of shingles out over the roof so work will flow continuously. Helpful 0 Not Helpful 0. There is a smaller dashed line of stick down spots which is not ever covered by plastic tape that helps at the edge of shingles, but the main sticky strip is 2 or 3 times bigger, thus stronger and always needs to be uncovered!
Helpful 1 Not Helpful 0. Some experts will tell you to begin in the middle in a pyramid and work both ways which allows two shingling workers to work on that same section to achieve a more balanced look. Either way is fine. The roofing "felt" paper is asphalt impregnated material that acts as additional waterproofing. There are also "non-tabbed" shingle with laminated layers for a simulated wood shingle look that are, obviously, not "3 tab" but still require cutting to 5 different lengths for staggering the slots.
On steep roofs, toe-steps should be nailed to the roof with metal strips holding the toe-steps, to keep you and supplies in place -- as well as using safety ropes and a harness.
Helpful 11 Not Helpful Work from the bottom up. The first material installed at the eave is the drip edge. 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. Ice dam protection at the eaves. Well, your roof and the home under it need the same kind of protection that an ice and water protector is engineered to provide. This thin, self-adhering membrane is the next component and it gets installed over the drip edge.
Ice dam formation is best prevented by having a proper attic vapor barrier, adequate attic insulation and thorough ventilation ; however, an ice protection membrane is a wise roofing system component and is likely required by your local building code in cold climates.
At this time, any valleys on the roof should also 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. Underlayment for overall secondary roof protection.
Both offer you peace-of-mind protection beneath the shingles. While the asphalt shingles will be the primary water-shedding roof layer, there are many benefits to installing a roof underlayment. Remember that drip edge we installed at the bottom of the roof? 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 wind uplift.
Also, any wind-driven rain blowing on the rake edge would cross the top flange of the drip edge and go on top of the underlayment instead of beneath the underlayment where it could potentially cause a problem. 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 help keep the water running downslope.
Valleys can either be open 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 metal. Closed valleys are completed during shingle installation. The following table shows the high, average, and low costs of installing a shingle roof.
The average cost of installing a shingle roof includes materials and labor. However, you may have to include the cost of tearing down the old structure in various instances. You can install the new shingles over the existing structure in some cases.
Here, you will not incur additional labor costs. If only a part of the roof is damaged, you don't have to replace the entire roof. Sometimes a simple repair will suffice. Roof shingle repairs can be cheap or costly, depending on the extent of the damage. For instance, a minor problem such as a broken shingle can lead to water leakage or other extensive damage that may be expensive to repair. Do you want a shingle roof but are unsure what type suits your budget needs best?
You can compare the prices of different options available on the market as shown above. Remember, the final cost may vary depending on several factors, such as the area of the roof, location, and the contractor. Use an asphalt shingle roof cost calculator to get a more accurate estimate. The cost of roof shingles will vary depending on the material and style. For instance, asphalt shingles are cheap to buy and install.
Relatively, metal shingles are an expensive option. The lifespan of a shingle roof depends on the material and style. An asphalt shingle roof can only last for 15 to 20 years. Materials such as metal can last between 75 to years. Save my name, email, and website in this browser for the next time I comment. How long does a shingle roof last?
