Answer: It generally takes three bundles of shingles to cover 100 square feet (9.29 square meters). Asphalt shingle "bundles" are actually sealed in packages (the term bundle comes from wooden shingles which actually came tied up with wire in bundles). Measure your roof and buy appropriately. Measure the length and width of the individual sections of the roof, multiplying them together to determine the area. Add the areas of each section together, then divide by 100 to get the correct number of squares. Multiply this number by 3 to get the number of bundles you'll need to buy. This will help determine how the shingles will lay on the roof width. Most asphalt shingles are 3 feet (91.4 centimeters) in length. If your roof's width is not an even multiple of the shingle's length, you will have a partial piece on one end of each row. The bottom row of shingles must hang past the edge of the roof. For a wood shingle roof you would have to cut the shingles that go on the edge to create a straight line to accommodate this. Start removing the shingles at the peak farthest from the trash container, or the corner you want to collect the shingles in. Use a garden fork or a roofing shovel to pull them off quickly, use the hammer-method and go by hand for a more thorough job. Make sure that you protect the sides of the house and the windows during this process, such as by leaning a large piece of plywood against the house below where you are working. Otherwise you might break a window or damage the siding. 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. 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. Sweep the roof as clean as possible. Remove nails that didn't come up earlier. Reattach loose boards in the sheathing. Examine the sheathing for damage and rotted boards, replacing the damaged sections. Lay asphalt, felt-paper, or special waterproof underlayment, such as a self healing membrane, over the roof. Some roofers will use 15-pound (6.8 kg) roofing paper, which is an effective method, although the best method is a self sealing membrane with a rain screen. Staple this felt down, 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 avoid tearing the paper. 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. Use sticky back ice and water shield as underlayment where ice dams or leaf and twig dams are likely to build up, and at valleys and where the roof ends at a wall (wide metal flashing may also be used there). Install new flashing. Nail metal flashing called "drip edge" along the bottom edge of the roof deck near the gutters. You will also need rake edge flashing for the sides of the roof. Make sure to install flashing around the chimneys and walls. These types of flashing are known as step flashing and turn back flashing. 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. 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. 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. When you are laying felt paper, make sure that the lines on the paper are running in a square pattern.

Problem: Write an article based on this summary: Make sure you have a fresh breath. Make sure you're looking good. Find a nice place to kiss. Try doing something to break the touch jitters away by flirting physically. Make sure that you both are ready for the kiss.

Answer:
Fresh breath is important for kissing because you want to give the boy as many excuses as possible to keep on kissing you. Try using lifesavers or mints and always brush your teeth before you meet up with him. Remember, bad breath isn't the end of the world but avoid it if you can. Try not to eat strong, spicy, or garlicky food before you see him. Again, if you can't avoid it, it's not a huge deal but it's better to avoid it altogether. You can't always plan when and where you'll kiss a boy, but you can try to be prepared. If you're dressed pretty and in a way you feel comfortable, you'll have a spring in your step. That means you will be more confident. More confidence means that there's a bigger chance the boy comes back to kiss you again. Don't necessarily wear lip-gloss, and don't wear heavy lipstick. Lip-gloss and lipstick, especially, will rub off on your partner, making him look sparkly or sloppy, depending on the situation. Stick with lip balm instead. Don't wear a bunch of accessories like hats, or wear your hair so that it gets in the way. Boys like natural beauty anyway. You may want to try kissing the boy when you have your hair up, so that he focuses only on you and the kiss, not the hair tickling his face. Public places are generally not so good for the first kiss, as you can get people staring at you or even heckling you. Try to find a place that's public, but still intimate, for you to share your first kiss. This will not only make him understand that you like him, but will also give him some time to adjust to you, so that you're not going from 0 to 100 in a second. Hold his hand or put your arms over his shoulders. Start moving your body so that he's much closer to you; it'll be awkward if you have to move a long way to kiss him. Touch his hair or face to make him know that you are interested. Gently touch his nose with your pointer finger and smile at him. You can even try hugging him first, and while you're still hugging him, lean back and go in for the kiss. This creates a connection from the very moment you hug. This means both physically and emotionally. Kissing says "I like you more than just a friend," and it's sometimes hard to save a friendship after you have a relationship. If you're not sure whether you're doing the right thing, wait until you absolutely know. Look at him in the eye. While he's watching you, look slowly towards his lips and back again. If he does the same to you, then he's ready. If he looks a bit uncomfortable and looks away, it's best to leave it for a while.
