#*Pry up the nails and loosening the ridge caps. It's ok if you don't get all the nails at first, because you'll have a chance to go back through and remove them later. | #*Pry up the nails and loosening the ridge caps.

#*Remove the metal flashing around chimneys, vents, and valleys in the roof. Flashing in the valleys will almost always be trashed, especially. Some roofers will keep some of the flashing that's in good shape, but it's probably worth junking it all when you've got the chance. | #*Remove the metal flashing around chimneys, vents, and valleys in the roof.

| − | #Clean the roof. Sweep the roof as clean as possible. Remove nails that didn't come up earlier. Reattach loose boards in the sheathing.

#Install underlayment and new flashing. Lay asphalt, felt-paper, or special waterproof underlayment, over the roof. Some roofers will use 15-pound (6.8 kg) roofing paper, which is an effective method. Be generous with the staples while attaching the paper to the roof deck. Use "tin caps" under staples, if the roof may be exposed to wind before shingles are to be applied. | #Install underlayment and new flashing.

#Choose the kind of starter course you will use. You can use narrow tab-less starter shingles if you bought some (GAF Pro-Start is one such brand), or will be cutting your own starter shingles to fit the particular project. Some people like to only have to buy one variety of shingle and cut them to fit, while others prefer the ease of the pre-cut starter shingles without tabs. | #Choose the kind of starter course you will use.

| − | #Use chalk lines to make a guide for yourself. Depending on the type of shingles you're using and the roof you're working on, you may need to marking a chalk guideline beginning 7 inches (17.8cm) from the bottom roof edge. In either case the glue strip of the starter course is then placed along the drip edge, and at the rake edges as well.<ref>http://www.gaf.com/Roofing/Residential/Products/Starter_Strip_Shingles</ref> | + | #Use chalk lines to make a guide for yourself.

#*Mark from the left to right edge of the roof so the chalk line will be seen immediately above each course as a guideline. Continue to chalk additional guidelines based on the width of the shingle through at least four courses (rows) across the roof. | #*Mark from the left to right edge of the roof so the chalk line will be seen immediately above each course as a guideline.

| − | #Cut your starter-course shingles if necessary. If you are making your own starter shingles, cut the tabs off for the "starter course" (bottom row) of shingles. To prepare the tabs and lay the starter course, shorten the first starter shingle by 6 inches (or about a half of one tab).<ref>http://www.gaf.com/Roofing/Residential/Products</ref> Place the glue strip at and all along the drip edge, and the rake edges as well. You will shingle over this starter course, so the bottom course will be double thickness. | + | #Cut your starter-course shingles if necessary.

#*Instead of cutting off all three tabs, you can also reverse the shingles for a starter course, so that the entire shingle with tabs turned upward are under your first course of shingles. With either method, putting the solid edge 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 course laid over the starter, thus not to expose the asphalt roofing paper through the slots of that bottom row. | #*Instead of cutting off all three tabs, you can also reverse the shingles for a starter course, so that the entire shingle with tabs turned upward are under your first course of shingles.

A continuous bead of asphalt could trap condensation or windblown water under the roofing at some point. |
#Cut five different lengths for staggering slots. To make sure you've got the right 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 1/2 tab from aligning with the slots in shingles above and below. Keep all scrap, especially any single tabs for use on the ridge cap shingles. Make the following cuts: | #Cut five different lengths for staggering slots.
