Terracotta roof wildlife exclusion in Belford, NJ

Before	After

As any roofer will tell you, terracotta clay-based ceramic roofing tiles can be challenging to work with. Although they are heavy and durable, if accidentally dropped or stepped on, these types of tiles can easily be broken. Terracotta tiles are installed by placing overlapping and interlocking rows of them on the roof. Although clay roofs are built to last and have been around long before asphalt shingles, repairing them can be a big hassle.

In order to access any tiles that are further up the roof from the eaves, you have to get to them without breaking any.  Because the weight of a person walking on the roof is more than enough to break these clay tiles, roofers often use boom trucks. When pieces have to be replaced, if the tiles are hooked over fasteners, you have to go under the piece and cut the fasteners since the overlapping tiles cover the fasteners. If the tiles are glued down, you may need a hammer and chisel. When I think of what roofers who work with terracotta tiles have to do, it makes me glad that I’m just a wildlife technician who only risks getting bitten or scratched by a nasty raccoon or sprayed by a skunk!

I was sent to a home in Belford, NJ to perform a wildlife exclusion along with one of our home improvement specialists. A wildlife exclusion is any project where we seal wildlife entry points (often on or around the roof) to prevent a re-infestation. With this home, raccoons were gaining access through a small area of a terracotta roof that had been damaged. According to the homeowner, this area had been previously patched, but the person doing the repairs failed to secure it properly leaving the gap vulnerable to wildlife.

We were asked by the homeowner to perform an exclusion to this area to ensure that any raccoons in the neighborhood stayed out. For this project, we measured and fit a piece of “trim cool,” aluminum fascia trim, in place that fit together like a puzzle piece. This trim blended into the roof, and just as important, was able to be secured correctly in order to prevent any wildlife access.

We often use trim cool to do repairs because of its flexibility. More and more, we are seeing fascia boards are covered with this product because of its resiliency to the outdoor elements. Homeowners don’t have to worry about peeling paint, wood rot, or wildlife gaining access to your attic by clawing their way through weakened wood.

Large opening attracts rats in Belford, NJ.

Before	After

Recently, a homeowner residing in the coastal community of Belford, NJ contacted Cowleys because of a suspected mouse infestation. Upon arrival, I inspected the areas where there were rodent droppings. The size and shape of droppings contain a wealth of information (in addition to a wealth of pathogens and parasites!). As you’d expect, the size of the droppings is related to the size of the animal. A house mouse, which weigh less than an ounce, produce very small droppings, about the size of a grain of rice, and their droppings often have pointed ends. Rat droppings. Rats weigh many multiples more than a mouse, averaging 8 ounces or so, and not surprisingly their droppings are much larger and often have blunted, rounded ends. The holes I found were big enough for a rat. Although rats need a larger entry hole, it’s not by much. A mouse can enter a hold about the diaper of a dime while rats need a space about the size of a quarter. I told the homeowner the bad news that this was a rat infestation, but the good news is that this infestation would be resolved, and resolved quickly.

I started by cleaning up all of the droppings, which pose a serious health risk. When rodent droppings dry out, particles can become airborne carrying aerosolized viruses including Hantavirus, a potentially fatal respiratory disease. We can’t stress enough the dangers of rodent droppings in an enclosed area. They are a serious biohazard. After finishing up with cleaning the rat mess, I sealed the two entryways being used to access the living areas of the home, one in the kitchen and one in the closet. Because these holes were so large, I used hardware cloth instead of plugging the holes with copper mesh. 

Mice and rats typically enter homes through openings around the foundation, first finding their way into the crawl space or basement. From there, thy travel through wall voids to forage for food and water throughout the home. I located potential access points in the crawl space and also baited the areas where there were indicators of rodent activity. I’m confident that this rat infestation will be resolved quickly with their entry points sealed and the bait stations set up. There should be no more rodent activity in the home’s living areas. I scheduled a two-week follow-up to re-inspect, replenish bait as needed, and apply additional treatments if necessary. Before leaving, I assured the homeowner that there should be an immediate reduction in the quantity of droppings, and if not, to contact us immediately. Although rodent treatments work quickly, they are not instantaneous. It takes some time for those rats inside the home to be eliminated.

Squirrels Ruin the Gable Vent in Belford, NJ

Before	After

This homeowner in Belford, NJ, had an infestation of squirrels in her attic. How did they get in? They ripped a portion of the gable vent off and entered that way. Nuisance wildlife infesting a home through the gable vents is very common. Over time, the gable vents get weathered so nuisance wildlife like raccoons, squirrels, birds, and bats have no problem ripping away these vents to find shelter inside a home.

A short while ago, we successfully retrieved all the squirrels and relocated them to a new, humane location. All that's left is exclude the main access in order to prevent future intrusions! First, we disinfected the attic area, went back to our trucks to fashion a louvered gable vent, and then installed it over the gable vent. This material is made out of heavy-duty Galvannealed steel (which means it won't rust) and is customized to accommodate vents of all shapes and sizes! Now the gable vent is properly protected from squirrels as well as all nuisance wildlife!
