The roof is one of the most important parts of your home. If you don't take steps to maintain it, problems can develop quickly. If your roof is in relatively decent shape, putting off a roof inspection for another year may be tempting, but some issues may come back to haunt you if you fail to notice them in time. Roof repairs should ideally be done as soon as a problem is recognized. If you want to get a good understanding of the state of your roof and also make sure that there are no developing issues that may impact your home in the future, ask for a professional inspection at least once every two years.
