Thanks for stopping by to see how we liked our new Duraflo roof vent guards. When we called DeLuca roofing to install new shingles on our house we were very happy to hear that Mike Strecker had a new product to show us to protect the vents. We have raccoons, squirrels, chipmunks etc. in our neighbourhood and the evidence was there on our roof that they were attempting entry into the house. The new Duraflo vent covers are working like a charm. My only comment would be that it would have been nice to have a colour choice. As our roof is a two tone brown, brown covers would have been nice. However, colour is NOT a issue when it comes to protecting the house. Not only did we get a stellar roof with DeLuca, everyone from Mike, to roofers to the flashing guy, were great. We are very impressed with both the roof and “critter guards”. Thanks again for taking the time to survey your product on location.
