It is highly recommended to have a professional roof inspection and possibly repaired by a professional at least once every three years. If you live in an area with extreme weather conditions such as high winds, hail and heavy snowfall, it’s a good idea to inspect your roof more frequently. Doing so can help ensure that any damage caused by extreme weather conditions can be seen and taken care of sooner rather than later, helping you avoid costly repairs down the road. A professional roofer will be able to identify any signs or problems with your roof that could indicate it needs repair or replacement. They may also be able to provide maintenance services such as cleaning out gutters, removing debris from the roofing surface and sealing exposed nail heads if necessary.
