The main justification most people give for doing this work by themselves is their desire or need to cut out the cost of labor and thus reduce the metal roofing pricing. Employing an experienced person really means employing his skills and superior knowledge, but that also means that he can fairly charge you much more when he puts in his valuable time on your project.
Many people feel like they can take on a big ‘do it yourself’ project like metal roof installation because of the detailed instructions that are often provided by manufacturers. There is one retailer that claims that instructions were given to a married couple who not only completed the project, but remained married in the process! Of course, this retailer is referring to such explicit instructions that the couple had no need to argue over how to complete the project.
Also, many people are worried about ‘scam artist’ contractors that seem to be popping up all over the country. These contractors will come in, give an estimate, ask for a deposit or for all of the cost up front, and then disappear. They will not return, often having done little or none of the work at all. However, using a contractor that has been in the business for awhile and has built a good reputation can solve that concern.
There are also many reasons why hiring a contractor can be a good idea. As stated before, he is going to be knowledgeable about the project. Chances are, those costly ‘first-timer’ do it yourself errors will not occur with a licensed contractor. He is likely to know what all of the metal roof installation regulations and guidelines are to pass inspection and more importantly to do a quality job. Also, he should be able to minimize materials and labor costs by doing the job efficiently.
A metal roofing contractor will be able to fix any issues that might arise with the workmanship upon completion. If a roof is done manually by himself, then any mistakes associated with it will be his own to deal with.
