Reviving a 15-Year-Old Asphalt Shingle Roof in Baden, Ontario
When Tony reached out to us about his home in Baden, his roof had reached a stage that many homeowners recognize with a sinking feeling. At 15 years old, the asphalt shingles were aging quickly, drying out, and turning brittle. Moss and algae had also begun to take hold across the surface, adding to the sense that the roof was heading toward the end of its useful life sooner than it should. For most people, that combination of symptoms points straight to a full tear-off and replacement, a project that carries a significant price tag and considerable disruption.
Rather than assume replacement was the only path forward, we looked at whether Tony's roof was a good candidate for rejuvenation instead. The shingles were deteriorating, but they were still intact and serviceable, which made this roof exactly the kind of asphalt-shingle surface that can benefit from preventative treatment. Choosing rejuvenation meant Tony could restore the health of the roof he already had, address the moss and algae growth, and postpone the expense of replacement, all without the mess of a demolition.

Project Overview
This project involved a single asphalt-shingle roof measuring approximately 2,000 square feet, finished in black shingles. Completed on August 10, 2021, the work centered on rejuvenating the existing roof rather than replacing it. The goal was straightforward: treat a roof that was drying out and losing flexibility, clear away the moss and algae that had established themselves, and extend the roof's serviceable life. At a treatment cost of $1,800 compared with an estimated $15,000 to replace the roof outright, the approach was designed to protect Tony's investment while deferring a much larger expense.
The Roof Condition
By the time we assessed Tony's roof, the signs of age were clear. The shingles were aging quickly and had become extremely brittle, having dried out to the point where the roof was deteriorating at a noticeable pace. On top of that structural aging, moss and algae had begun growing across the surface, the kind of organic growth that thrives on an older roof and tends to accelerate its decline. Taken together, these were the classic markers of a roof that still had life left in it but needed intervention to keep from failing prematurely.
The Treatment
Our team carried out a full rejuvenation of the shingle roof using Reactiv8 Shingle Rejuvenation. The treatment is applied directly to the existing asphalt shingles, working to restore the flexibility that dry, brittle shingles lose over time. Rather than covering up the problem, the process addresses the underlying condition of the shingles themselves, helping them behave more like a younger roof. As part of the work, the moss and algae that had taken hold were cleaned from the roof, and the treatment was applied to help prevent that growth from returning. The entire project was completed in a single visit on August 10, 2021, with no tear-off, no landfill waste, and none of the upheaval that comes with replacing a roof. For a 2,000-square-foot surface, this meant Tony's home was protected quickly and cleanly.
The Results
The outcome speaks to why rejuvenation made sense for this roof. The brittle, dried-out shingles regained flexibility, the moss and algae were removed, and steps were taken to keep that growth from coming back. What makes this project especially compelling is that our company owner, Larry, was able to see the results hold up over time. When he returned five years later to reapply Reactiv8, the roof, then 20 years old, was in better overall shape and noticeably more flexible than it had been in 2021 at 15 years old. The moss and algae remained under control as well. By treating rather than replacing, Tony spent $1,800 against an estimated $15,000 replacement, an estimated savings of roughly $13,200. As with any maintenance treatment, savings figures are estimates rather than guarantees, but the long-term improvement Larry personally witnessed is exactly the kind of result this approach is meant to deliver.

Homeowner Feedback
Reactiv8 is a great product. I am impressed with how it has rejuvenated the flexibility of the shingles and prevented the moss and algae from coming back.
