Keeping your roof in a good state is a good idea and can help you get properly prepared for major weather events, which often have destructive effects. A clean Austin roofing system has more chances to withstand harsh outside conditions.
You could start with your gutters and downspouts. Especially during the hot season, leaves, branches and debris can get accumulated in your gutters. Rainwater can overflow your gutter system, which leads to more problems such as damage to your siding, roof and trim. It is equally important to do the cleaning one more time, in the fall, when all the trees are bare. A good idea can be to install guards and screens for your gutters.
After the cleaning is done, you can check your roofs for problems such as cracked or missing shingles, frayed edges, and so on. Remember also to check your skylights, chimney, vent stacks, etc. In case you are worried about getting up on your roof, you can do the check from ground level, with the help of some good binoculars. You can use the binoculars even if you climb on top of your roof, as this can enable you to stay in just one place, without having to walk back and forth.
