When you have a few shingles on your roof that need to be replaced, it makes sense, and cents, to do it yourself. You save quite a bit of money doing it yourself over calling in a professional roofer. However, if you are not stable on your feet while up high, then err on the side of caution and have someone with the tools and experience come in to do it for you. Should you feel fine up at the top of a ladder or walking around on a graded surface, then going through and repairing your shingles should be no problem to do!
You want to make sure before you head up that ladder that you are totally prepared. After all, once you get up there, you really are not going to want to get down to grab something you forgot. You want to make sure you have shoes on that have good traction, and you want to wear a safety hat.
You should opt for safety glasses, and you should also make sure you do not go up that ladder without any heavy-duty gloves. You will want to make sure that you are wearing a stocked tool belt when you go up there, with roofing nails and a hammer, plus plyers, some type of pry bar, and a screwdriver with multiple heads on it, just in case.
Ideally, you will also want to make sure that you have the items with you to create a roof jack, as that gives you a small, secure platform to stand on. This way, as you need to work on a small area of the top of your building, you can squat down, do your work, and then stand up when you are done without being at risk.
If the shingle is still attached, make sure you take a look around it. If not, then look where the shingle was. You want to look at the shingles that surround the area where the damaged shingle was, and make sure there is not any damage to those shingles or the roof itself. You want to make sure the flashing is still intact, and you want to make sure that there are not any tears or cuts that could let water through to the attic area underneath.
When a single shingle needs to be replaced, all you are going to have to do is slide the new shingle where the old one was, and secure it. However, if you are seeing damage to areas that surround where the damaged shingle came from, you may need to do more replacing than originally anticipated. If you find your entire roof needs to be replaced, you should opt to have the professionals do it instead, as they are going to be able to do it for less money, faster, and with a better end result than someone who has never done it before.
Ideally, when you need to replace just one or two shingles, you should try and do it when the sun is out and the weather is cool. You never want to be up on the roof in severely cold or hot weather, as that can not only be dangerous, but also make it to where the shingles do not line up properly since they shrink and expand with the weather.
If you find your shingles difficult to pull out from the rest, wet them with a little bit of water so they wiggle around easier. Use the claw part of your hammer to make sure the nails are loosened, and then wiggle the shingles out from the area they were stuck in. Once you have the old shingles out, it is time to clean up the area to ensure there is no debris in the way that could hamper the new shingle going in.
Lift the old shingles, and slide the new shingle up into the old shingle’s place, allowing the shingles to match up so it looks like there aren’t any problems with them. Nail the shingle down to the tar paper, and use a little caulk or adhesive around the outer edges to ensure that the shingle is sealed down to the roof.
If you notice any other shingles in the area that are loose, secure them down while you are on the roof. The last thing you want is to be back up their next week!
