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 that roof inspection for another year may be tempting, but undetected problems may come back to haunt you if you don't catch them quickly. Roof repairs should ideally always be done as soon as possible. If you want a better understanding of your roof's condition, and catch issues before they become severe problems, get a professional inspection at least once every two years.
