Roof rejuvenation is a process that extends the life of your asphalt shingles by restoring their natural oils and flexibility. At Green Shield Bio-Tech, we use a 99% bio-based formula to achieve this.


Our rejuvenator penetrates deeply into the shingles, restoring lost oils and providing UV protection. It’s applied using a soft wash system for even coverage.


No, our application method does not require the removal of solar panels, saving you time and money.


Our treatment comes with a 5-year warranty, but many customers report extended benefits beyond that period.


Yes, our formula is 99% bio-based and low in VOCs, and free of microplastics making it an eco-friendly choice for roof maintenance.


Heavy damage may require repair/replacement, but our free inspection determines if soft washing or rejuvenation is suitable.


Soft wash annually; rejuvenate asphalt every 5–7 years (up to 3 times), cedar every 5–10 years.


Calgary-owned, eco-focused, using biodegradable solutions and bio-based rejuvenators.
