Problem: Article: Go into your attic and find a spot at least 2 feet (0.61m) down from the peak of your roof. Use a hammer to pound a nail through to the roof. The nail will either visibly stick out from the roof or raise shingles so you know where it is. Make sure the nail is in between the rafters so you can fit the vent between them. If you don't have the room to swing a hammer, use a drill and a long screw. Get on your roof using a ladder and locate the nail. Use a claw hammer to loosen and remove the shingles around the nail to clear a space equal to the opening on the bottom of the vent. Otherwise, cut out the shingles using a utility knife. Once you're finished, draw a square outline the same size as your vent on the roof. Only get on your roof if you're comfortable doing it. Otherwise, hire a professional roofing service to come install the vents for you. Set the saw depth so it only cuts through the top of your roof and not any rafters. Turn the saw on and follow along with your outline until the square is completely cut out. Lift the boards out or push them into your attic to throw away later. Wear protective eye gear to prevent getting sawdust in your eyes. You can saw through your shingles and roofing at the same time if you have a roofing cutting blade for your saw. The flanges on your vent should slide underneath the surrounding shingles easily. Use a caulk gun to squeeze out an even layer of the adhesive around the edges of the hole. Set your vent on top of the hole so it lines up and press it down so it adheres completely. Roofing tar and caulk can be purchased in an easy applicator tube at your local hardware or home improvement store. Nail down the corners of the vent first to keep it in place. Add more nails along the sides every 45in (1013cm) so it doesn't come loose. Some vents will have holes where you can place nails, but some will not. Place a line of roofing tar or caulk on top of the vent's flange, or its bottom flap, using a caulk gun. Press new shingles onto the caulk and use nails at the top of each shingle to fully secure them to the roof. Cover the entire flange with shingles to integrate it better into the roof. Cut the shingles to fit around the vent with a utility knife if you need to.
Summary: Drive a nail through your attic to mark where you want your vent. Clear the shingles in the area to make room for the vent. Use a circular or reciprocating saw to cut through your roof. Place a layer of roofing tar or caulk around the hole and press the vent down. Secure the vent in place with nails. Glue down shingles to cover the bottom of the vent.

Problem: Article: Scientists research and develop flu vaccines that are designed to prevent infection from the most likely strains of flu viruses. Every year the vaccine is different, so getting it one year does not protect you for the next round of flu season. Getting the flu vaccine is key in controlling the spread of the flu. The flu vaccine protects you from the flu, not from other contagious illnesses you may be exposed to. Upper respiratory illnesses, like a cold or the flu, are spread from person to person. A common way these illnesses are spread is by touching someone or something that has been contaminated with the virus. Wash with warm water and soap placed in the palm of your hand. Lather your hands by rubbing them together for at least 20 seconds. Be sure to cover all surfaces of your hand, including between your fingers, under your nails, and your wrists. Then rinse your hands well, use a paper towel to dry, and use a towel to turn off the faucet. Discard in the towel in the trash can.germs off your hands by wash Squirt gel into the palm of your dry hand. Rub your hands together covering all surfaces until the gel dries. This takes about 15 to 20 seconds. The flu virus can be spread by someone sick as far as six feet away. Coughing and sneezing creates tiny droplets that can travel through the air, landing on someone's hands, their mouth, nose, or inhaled directly into their lungs. Door knobs, desks, pencils, and other objects can carry the virus germs from one person to another. Once you touch an object that has been contaminated with the virus, it is easy to then touch your mouth, eyes, or nose. This provides a way for that unwanted virus to enter your body. The flu virus can live for two to eight hours on surfaces. If you get sick, avoid contact with other people until your symptoms improve or your doctor says you are not contagious. In the United States, estimates show that between 5% and 20% of the population get the flu every year. More than 200,000 people are hospitalized each year for complications and, each year, thousands of people die. The elderly, babies, pregnant women, and people that have compromised immune systems, or have asthma or other lung diseases, are at the greatest risk of developing complications. Protecting yourself from exposure, and preventing exposure to other people if you do get sick, can possibly save lives. Try to stay in an isolated room at home, separate from other family members (especially kids) to avoid spreading the illness. Don't go to work or school, and don't send your children to school or daycare when they are contagious. Coughing and sneezing into a tissue, or even into the bent part of your arm near your elbow, is better than spreading the infected droplets into the air. Bed sheets, towels, dishes, and utensils should be washed carefully before being used by other people.
Summary:
Get the flu vaccine yearly. Wash your hands. Use soap and water. Clean your hands with alcohol gel. Avoid contact with people that are sick. Be aware of surfaces you touch. Protect yourself and other people from exposure. Stay at home, isolated from other people. Cover your mouth when coughing or sneezing. Avoid sharing items.
