Short Answer
Acrylic and silicone are both reflective liquid coatings, but they solve different problems. Silicone handles standing water and UV exposure better than acrylic does. Acrylic costs less and is easier to recoat down the road. If your roof doesn't have a ponding water problem, acrylic is usually the more practical choice.
Side By Side
Where they actually differ
| Acrylic | Silicone | |
|---|---|---|
| Cost | Lower, our standard reflective coating | Higher, priced for its ponding water resistance |
| Lifespan | Standard recoat cycle applies | Strong UV stability, but harder to recoat once weathered |
| Disruption | Standard surface prep | Stricter prep required, doesn't bond well over a dirty or weathered surface |
| Warranty | Follows the Conklin Snow Leopard system | Varies by manufacturer, confirm before assuming NDL terms apply |
How We Decide
Why we don't default do silicone
Silicone's one real advantage is standing water tolerance, it doesn't break down the way acrylic can under prolonged ponding. But that strength comes with a real tradeoff, silicone gets slippery when wet and is notoriously difficult to recoat once it's weathered, since new coating often won't bond to old, chalked silicone without extra prep and cost. If ponding water is the actual problem, urethane is usually the better fit within our own product line before silicone even enters the conversation.

FAQ
Straight answers
Is silicone actually better than acrylic?
For standing water and UV exposure, yes. For cost and long term recoat ease, no. It depends on what your roof actually needs, not which one sounds more advanced.
Can silicone be recoated the same way acrylic can?
Not as easily. [ Placeholder: confirm specific recoat requirements and any special primer costs for aged silicone with Justin before this goes live. ]
If my roof has ponding water, should I get silicone?
Possibly, but urethane is usually the better fit within what we install, worth an inspection before deciding either way.
