   Remove former shingles and flashing. Starting time removing the shingles at the peak farthest from the trash container or the corner y'all desire to collect the shingles in.

Make sure that you protect the sides of the house and the windows during this process, like past leaning a large piece of plywood against the firm below where y'all are working. Otherwise yous might break a window or damage the siding.

   • Pry upwardly the nails and loosening the ridge caps. Information technology'south okay if you lot don't go all the nails at outset considering yous'll take a hazard to go dorsum through and remove them subsequently.
   • Remove the metallic flashing effectually chimneys, vents, and valleys in the roof. Flashing in the valleys will about e'er be trashed especially. Some roofers will proceed some of the flashing that's in expert shape but it'south probably worth junking information technology all when you've got the chance.

4. 4

   Clean the roof. Sweep the roof as clean every bit possible. Remove nails that didn't come up earlier. Reattach loose boards in the sheathing. Examine the sheathing for harm and rotted boards, replacing the damaged sections.^[ii]

5. five

   Install underlayment and new flashing. ^[three] Lay cobblestone, felt-paper, or special waterproof underlayment, such as a cocky healing membrane, over the roof. Some roofers will utilize 15-pound (6.8 kg) roofing paper, which is an constructive method, although the best method is a cocky sealing membrane with a rain screen. Staple this felt downwards, starting at the lowest point of your roof and working upward. Overlap each row at least 3 inches. Use plenty of staples and work carefully to avert tearing the paper. Be generous with the staples while attaching the paper to the roof deck. Use "tin can caps" under staples if the roof may be exposed to wind before shingles are to be practical.

   • Use sticky back ice and water shield as underlayment where ice dams, leaf and twig dams are likely to build up, and at valleys or where the roof ends at a wall (wide metal flashing may as well exist used at that place).
   • Install new flashing. Nail metallic flashing chosen "drip edge" along the bottom edge of the roof deck most the gutters. You will likewise need rake edge flashing for the sides of the roof.

Y'all tin can utilize narrow tab-less starter shingles if you bought some (GAF Pro-Offset is i such make) or will be cut your own starter shingles to fit the item projection. Some people like to just accept to buy one multifariousness of shingle and cut them to fit, while others prefer the ease of the pre-cutting starter shingles without tabs.

7. 7

   Use chalk lines to make a guide for yourself. Depending on the type of shingles you're using and the roof y'all're working on, you may need to marking a chalk guideline showtime vii inches (17.8cm) from the bottom roof edge. In either instance, the glue strip of the starter grade is and so placed along the drip edge and at the rake edges as well.^[4]

   • Mark from the left to right edge of the roof and then the chalk line will be seen immediately above each course every bit a guideline.

   Cut your starter-grade shingles if necessary. If you are making your own starter shingles, cutting the tabs off for the "starter course" (bottom row) of shingles. To ready the tabs and lay the starter class, shorten the first starter shingle by 6 inches (or about a half of one tab).^[5] Place the mucilage strip at and all along the drip edge equally well as the rake edges. You volition shingle over this starter course, then the lesser grade volition be double thickness.

   • Instead of cutting off all three tabs, you tin besides reverse the shingles for a starter course and so that the entire shingle with tabs turned upward are under your get-go course of shingles. With either method, putting the solid border at the drip edge and cutting 6 inches off the length of first starter shingle prevents the slots between the tabs from lining up with the first regular class laid over the starter, thus non to betrayal the cobblestone roofing paper through the slots of that bottom row.
   • Smash the shingles with no tabs, such as precut Pro-Start shingles,^[6] and apply asphalt cement from a caulk gun in many dots along the drip edge under the edge, then press the tab-less shingles downwardly onto the line of cobblestone cement dots with acceptable spaces betwixt the dots. A continuous dewdrop of cobblestone could trap condensation or windblown water under the roofing at some bespeak.

   Cut five different lengths for staggering slots. To make sure you've got the correct sizes to lay courses correctly, cut several sizes of shingles from the three-tab variety you purchased. Cut off one-half tab-width of the first tab to start the first course. Each cut is needed to shift the slots of the shingles on the course of shingles a one/ii tab from aligning with the slots in shingles above and below. Go on all scrap, especially any single tabs for utilize on the ridge cap shingles. Make the following cuts:

   • Cutting a half tab off for your get-go form shingles,
   • Cut off a full tab for your second course shingles
   • Cut one and a half tabs off of your third course shingles,
   • Cut ii tabs off your 4th grade shingles
   • For your fifth course, cut off half of the final tab
   • Keep your sixth course tabs intact

3. three

   Start laying courses. Nail the "cut off shingle" into identify, about 6 inches from its lower border. Hammer in one nail near 2 inches from each end of each shingle and another smash nigh 1 inch above each cutout. Make sure to continue nails out of the tar strip equally you lot work.

   • The adjacent shingles above should comprehend the nails past about 1 inch vertically. Horizontally, end nails volition exist covered past up to about ane/2 of a tab, of the shingle(southward) above. Exist sure that these nails volition hold the top border of the course of shingles immediately below.

4. 4

   Put a full shingle up against the cut shingle and nail into identify. Repeat this basic design, alternating shingles across the roof, working toward the right side, using the chalk line to proceed 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.

5. 5

   Cut the final 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 downwards after it is nailed on, if you similar. Keep this process to the 5th row then brainstorm the aforementioned procedure as the showtime row beginning with a full shingle and a chalk mark. Repeat all of the way to the ridge.

   • If information technology is a hip roof, let about a tab width to overhang onto the next section of roof at the hip to help strengthen the articulation in that location.

   Install the last form. Bend the last course of shingles over the ridge, up to about half-dozen inches, and blast it onto the other side and so that the roofing extends over the acme of the ridge, where nails will exist covered, leaving no exposed nails. However, do not do this if a ridge vent organization is being installed as well. About all modern roofs use ridge venting – the sheeting stops brusk on each side. Finish your concluding shingle row hither, 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, first at the end putting a bead of asphalt under the first ridge shingle to hold downwards the tab. Nail information technology where the side by side ridge shingle volition cover the nails about an inch horizontally and vertically.

2. 2

   Install the ridge shingles. With the asphalt granules exposed, across to the other terminate, boom 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.

3. three

   Utilise a heavy bead of cobblestone cement. Dot the cement under and around the border of the terminal ridge shingle where you removed the smash line. Nail at the 4 corners to the end of the ridge and add a little dab of tar to cover the nail heads.
