Your roof should be inspected at least once a year, according to Zillow. However, it's also important to check the roof after any extreme weather event, such as hail, snow or wind, and look for any leaks inside. The National Association of Roofing Contractors recommends that you have your roof inspected twice a year. This will help detect and prevent any major problems before they become too serious.
If you've experienced a major weather event, such as a snowstorm, it's best to have your roof inspected as soon as possible. The standard rule in the roofing industry is that you should inspect your commercial roof twice a year - in spring and fall - before each extreme season. This will ensure that the roof is prepared for the upcoming change in temperature and other potential dramatic weather conditions. It may be difficult to inspect your roof as often as recommended, but it will pay off in the long run.
If there's a major storm or other threat to the roof, make sure to follow up with a quick inspection. As the sun's rays hit the roof, the roofing material expands and then contracts when the sun sets. This can cause the roof to become less stable, leading to leaks, cracks and other problems. Immediately after damage to the roof is noticed or a major weather event occurs, it's best to call a contractor for an inspection.
This applies to any other material your roof is made of - make sure it's all there and not damaged. Hail can cause very serious issues that affect the roof in many ways. You don't need to physically climb onto your roof, and without the safety equipment that professionals use, it can be dangerous. Each of these different factors will affect the quality and stability of your roof in various ways.
Even new roofs should be inspected after these types of situations, because bad weather can damage or ruin a roof regardless of its age. If you have asphalt shingles, check the gutters for granules too. It's easy to overlook your roof, but it's what protects you from the elements. That's why it's important to have it inspected regularly by a professional.
