Here is a picture of a vent that is leaking. You can see the wood getting wet, which will rot it over time. Don’t let this happen, get some Critter Quitters and stop the leak before its a real problem.
Sorry to be so long in replying, but I just got the guards installed. The pre-cut was to the correct pitch, and they installed very easily. Makes the roof look much better and were immediately tested by two days of rain. You can count me as a satisfied customer.
Its worth noting that we don't get many testimonials anymore. Most of our units are now sold through Home Depot, so we very rarely get any feedback other than what is given to the Home Depot. But also the sales through Home Depot are easily three times that we were doing directly.
"Critter Quitters® are installed on my roof. Looks good. Awesome product!"
