Your Stained Roof Can Look New Again! Clean & Protect Your Roof With DEFY Roof Cleaner® and DEFY Stain Blocker For Roofs®

The most common culprit causing unsightly stains on asphalt roofs is a blue-green algae. Roof stains caused by algae attack start out as areas of light discoloration then turn to unsightly black or dark brown streaks.

Algae growth can cause damage to your shingles and shorten the life of your asphalt roof. Its growth holds water on the roof's surfaces which intensify the sun's ultraviolet rays like a magnifying glass.

Roofs darkened by algae growth can increase cooling cost by as much as several hundred dollars a year.

The increased moisture and UV rays work to dislodge the protective granules and attack the shingles asphalt coating. Moisture, UV rays, and thermal movement from temperature extremes are your roof's greatest enemies. All three are intensified by algae growth. It can suck the life from your asphalt roof leading to earlier than necessary roof replacement.

DEFY Roof Cleaner is the first effective roof cleaning product that does not rely on chlorine bleach or sodium hydroxide. These harsh chemicals can cause damage to your roof and kill surrounding vegetation. DEFY Roof Cleaner strikes the perfect balance between aggressive cleaning and not being harmful to the roof or surrounding vegetation. It's made of an optimized blend of detergents, coupled with a unique buffered chemical made from sand and soda ash, which is recognized as a non-pollutant.

DEFY Stain Blocker deep cleans the roof to prevent ugly stains from returning. Once the roof has been properly cleaned and rinsed it should be treated with DEFY Stain Blocker. It helps maintain the appearance of recently cleaned asphalt roof shingles, tile roofs, cedar roofs, and more. Maintenance coats should be re-applied about every 2-3 years or at the first sign of the stains return. The frequency of maintenance coats will depend on many factors such as climate, orientation of the roof and surrounding trees, etc. In extreme cases, maintenance coats may need to be applied yearly. In ideal situations, maintenance coats may only be needed once every five years.

Three Steps To A Cleaner Roof:

Clean - Apply DEFY Roof Cleaner. The Roof Cleaning Applicator can automatically dilute the cleaner 1:6. Allow the Cleaner to work for about 20 minutes.
Rinse - Rinse the roof clean. Using a 3 Head Roof Rinsing Tool will speed the rinsing process without damaging the shingles.
Protect - To help keep the roof looking new longer, apply a saturation coat of DEFY Stain Blocker.
