10 Best Chemical Roof Cleaning Solutions 2025 in the United States

The 30 SECONDS Pro Mold and Mildew Stain Remover is designed to tackle mold and mildew stains both indoors and outdoors without scrubbing, making it user-friendly and ideal for those seeking to avoid tough physical work. Its formula is twice as strong as the original 30 SECONDS Outdoor Cleaner, promising faster and brighter results. This product works on various surfaces such as wood, concrete, vinyl siding, and tile, making it versatile enough for roof cleaning and other household mold issues. The fresh scent is a nice touch since some chemical cleaners can have overpowering odors.

It comes ready to use in a large refill bottle, which makes application straightforward and convenient, although the product dimensions and weight suggest it may be somewhat bulky to handle. Since the effectiveness duration or how long the mold stays away after application isn't specified, repeated treatments might be necessary in damp conditions.

This cleaner is well suited for someone seeking a powerful, scrub-free solution for mold and mildew with easy application, but it is recommended to test a small area first on roofing materials before full use.

The Dicor RP-RC-1GL Deep Cleaning Rubber RV Roof Cleanser is designed specifically for cleaning RV roofs and exteriors, making it a good fit for RV owners who need a gentle but effective cleaner. It is biodegradable and unscented, which means it is safer for the environment and won’t leave a strong chemical smell during application. The product is sprayed on, brushed lightly, then rinsed off, so the application process is relatively simple and doesn’t require specialized tools.

It is also safe for all types of RV roofing materials, which reduces the risk of damage that some harsher chemicals might cause. Since it is meant to be used before applying roof coatings, it may be best suited as a preparatory cleaner rather than a standalone solution for deep or persistent stains.

This cleaner provides a user-friendly, environmentally conscious option for RV roof maintenance but may need to be paired with other products for ongoing roof protection.
