Another aspect of a residential roof replacement cost to consider is if your roofing company accounted for unexpected issues that may arise. This is something that varies from company to company and there are pros and cons to factoring in the cost of unexpected issues before a job begins.
If your cost is higher for your roof repairs because the roofing company likes to add in a portion that covers unexpected difficulties (as most jobs have something arise that they didn’t anticipate) this can be beneficial so you’re not caught off guard later and scraping to cover the new repairs. However, if your roof repairs are straightforward and nothing goes awry, you paid more upfront for a job you didn’t need to have completed.
Talk over your roof’s history with your roofing company if this is part of your roofing estimate to make sure the roofing estimate has everything you want it to have and doesn’t include anything extra you don’t want to worry about.
