If you have decided to install a brand new beautiful roof, then start learning and create a list of what you need to do. Being disorganized is the fast path to losing money and maybe even getting sued if someone gets hurt on the job. Your list of what needs to happen should have priorities on it for the things that are a little more important than others. All contractors (in the US) are regulated to some extent, and at least all your state and find out if there are any official complaints about the contractor you’re dealing with.
It is possible to have eroded areas or any kind of early signs of damage visible when you’re on the roof itself. What you need to do is survey all those places on your roof where there is something coming up from below as these tend to be the problematic areas. So you do have options available to you, and if you’re not afraid to be on the roof then that’s great because you can do this yourself. The reason for discovering problems on the roof is there may be other types of repair actions that need to be done from on the roof. There are all kinds of different situations in which the homeowner thinks a new roof is needed. There are too many nuances involved, and a good visual inspection is probably in order. If you bring in a roofing contractor, depending on who he is you may get a recommendation to replace the roof, completely. What you have to realize is that it’s your money and your roof, and obviously that entitles you to be in control. The best solution is to get several opinions, or ideally maybe someone you know or a friend of a friend type of situation.
If you are adventurous and capable, then consider doing the roofing job yourself. This is done all the time but not so much the majority of the time, and if you want to do your own work, then obviously you’ll need to do a lot of research. Probably the biggest expense for you will be buying the shingles, but you don’t need to buy the most expensive. It’s great to see your new roof being installed, but you need to keep your eye on the ball for issues. Sometimes the unforeseen can occur, and you just deal with it as it happens. Don’t be afraid to ask the installers about anything, and keeping you informed is part of their job, too. And do pay attention to what is being done each day, but it’s really not necessary to camp out on the lawn.
