No worries. The roof material is warrantied for 10 years and typically lasts 15 or more unless you tear it somehow. Awning fabric probably lasts 10+ years too, depending on the type (vinyl lasts longer than acrylic fabric). Chemicals are generally more harmful than good. Keep it clean (fresh water and mild detergent), use a good car or boat wax on the fiberglass, and inspect the roof seems and re-caulk as necessary every year and you will be fine.
