There are a couple of things you can do to prevent premature deterioration of your roof. You should always schedule routine roof inspections. At the very least you should schedule roof inspections at least once a year and perform preventive maintenance when needed. This will help ensure your roof stays in its best condition and prolong its life. Other important things to do to prevent deterioration is to ensure you have proper attic insulation and ventilation, clean out any debris build up such as leaves, cut and trim overhanging tree branches, always address any gutter problems and clogs, and always fix active leaks as soon as you notice them.
