Installing a new roof yourself is not recommended. But if you're considering whether or not you can do it, it's absolutely possible. Tearing off the old roof is just muscle and sweat. The truth is that anyone can replace their own roof with the help of the many DIY websites.
For residential homes, roof replacements usually take two days: the first day to remove the old roof and the second day to install the new one. Here's when you should and when you shouldn't, and what you should know about roof replacements and repairs to help you decide. If you have T-lock shingles, you'll need to replace the entire roof, as they're discontinued, but your insurance will normally cover the costs. If you have more technical experience, replacing a roof on your own will save you thousands of dollars in labor costs, but be realistic about your skills and strength.
Maybe you've seen how the roofs in your neighborhood have changed in two or three days and you assume that doing the work yourself may require another day or two, but that you can still finish it in less than a week, especially if you can get some friends to collaborate and help you. This synthetic layer, which replaces felt paper, covers the entire roof covering and is the second line of defense against leaks, after shingles. If you're a novice DIYer, doing small repair jobs, such as replacing shingles, is a smart way to learn more about how your roof works and save money.
