Shingle eating critters

What are they…any ideas.

Thanx in advance…

Perhaps same as roof vent eating critters…:wink:

So now we have shingle eating crabs in Florida, just great.

That looks like squirrel damage. They normally eat the tops off of the lead vent boots around here.

Funny thing is that I mentioned to client to have that vent replaced to prevent vermins like squirrel entry into the attic and later notice Realtor emailing vendor about squirrels being in the attic…

Yep, squirrels do the same to shingles and lead flashing in Illinois as well.

Squirrels are skittish enough as it is, what the heck does lead do to them? :shock:

That does not look like animal damage to me. It looks like shingles that were damaged (bent and cracked) during transport or installation and that over time broke along the line of weakness. If the roof had bonded properly there would still be pieces left along the adhesive line.
Also, the chew damage I’ve seen, they don’t chew nearly that large an area, and they chomp clean through with each bite. They don’t leave bits oft the mat hanging out, especially in a uniform manner like shown here. That said, breaking from bending is usually in a straighter line. Not repeated elsewhere on the roof? Was this near a point of squirrel access like a tree (not that they couldn’t get up there without a tree)?

That does look like chew damage. They like to get in there to have babies.

Kenton, I thought along the same lines but had to choose one. The irregular tear and my experience with hamsters and not roof forensics led me to believe critter damage.

So critters don’t eat asphalt shingles?

Thomas, Here in NH I see this all the time and it is from snow/ice removal…however I doubt in Florida that is too much of a problem for you. So I suggest tree branches rubbing on roof or perhaps prior removal of debris such as pine needles etc.

I’ve never seen chew damage bigger than a silver dollar Tom, but I’m in Colorado. Never seen photos positively identified as chew damage bigger than that either.

I don’t think any animals actually eat shingles, but birds like ravens and maybe crows will hack away at them, but that type of damage is usually at the peak near the roof edge and you’ll see bird droppings. I think at least some types of rodents have to chew to keep their teeth from growing too long.

Squirrels and raccoons sometimes try to chew and tear their way through a roof to gain access to the attic, but they usually attack weak areas like the base of valleys or roof edges where sheathing has been softened by leakage/decay. Also, the damage is usually concentrated in one small area and they can usually get through the shingles and underlayment but if they get stopped, it’s by solid sheathing.


I believe you are correct !
What next ?

Crabs are good eating! Just put a couple of rat traps up there on the roof, bait them with fish heads, tie them to the gutter and check them before dinnertime.

Uh Oh!
Hell ! They maybe the new HIT on southern menus?:smiley:
They need a name ?

They look like fiberglass shingles.
In FLA you guys get below freezing temperatures.
They are cracked like fiberglass shingles when you bend them or apply compression to a corner in cold weather, they break.
The defect even resembles thermal splitting separating the organic felt or compressed mulch Kenton.
Within the delamination layers appears to be strands of fiberglass running vertically if my memory serves me correctly. I say fiberglass shingles.
NOTE: I would have to taste one to tell if they are organic.:slight_smile:

Someone say bite marks from rodents? They may be organic I may add but Geese Louise mate get a grip.
PS: When I heard the word organic used to describe shingles the first thing I thought of," if I try to eat one either I burp after, Or I may fart…but most likely I will die because they are anything but organically eatable farm grown organic shingles that were loving nurtured from **Betty and John free spirit

Follow along every one:)…The short story of the once infamous organic shingle grown by farmers like Betty and John free spirit.
The young hippies we knew in college that are now owners of a chemical free farm and still smoke…well you know;)
They moved into a geodesic dome,like all loving hippies do wanting to see and feel if the female a s s was greener, opps…female grass, sorry for omitting letters, before they settle down to a life together.

The story goes…Betty and John free spirit inherited land. Yeaaaa they exclaimed BUT that farm needed to be certified organic when they first had the idea for income, for they wanted to grow something legal.:wink:
A friend told them :“The government pays you big time for growing (Organic Shingles)” A farmer named (Certain Teed) or (Mon Santo if you live in other parts of the world and use chemicals) , will pass by your homestead on horse and buggy and fill you in on the growing techniques need to be certified organic. He even helps with seed.
Yea they exclaimed…
To their word being founded in catholic, everything stated was true and Certain Teed the farmer told the young couple what to do.

For 5 years they did what was necessary. Farmer Certain Teed showing and helping with yearly evaluations showing no chemicals were used on the earth. No traces of chemical were in the soil. That their farm is certain distance from any farms farmer Mon Santo helps with.

Certain Teed kept records for them.

Yes organic shingle plants do exist and look like tobacco plants only 5X the size and weight.
In the old days the harvesters of Organic shingle had to be strong for each single wet leaf (shingle) weighed 18.333333333 pounds. 3 shingle leafs went into every bail weighing 55 pounds. Most harvesters carried 2 bundles per sholder. When dried and bundled the were 21 organic shingles leafs per bundle with each bundle weighing 77 pounds…

CURING shingles: The farmer would then lay them out wet leafs to dry on raised beds of imagination.
Knowing when they are about cured he sprinkling pixie dust on them to change their colors. NOTE: It had to be done at the last phase of curing as not to waste the magic fairies time for she would take away the rain bow. No more if that happened. Black and at times two tone black would be the only product you had for market that year.
Once the color applied and the drying complete the farmer did a loop de loo for they were ready for market.:slight_smile:

Bundling: 21 shingles went into each bundles and they were wrapped and labeled “100% Organic shingles” with farmer Certain Tweed doing most of the purchasing form the little markets dressed as a very pour hungry ingester of organic shingles. Most felt sorry and gave Certain Teed and lower rate than the rich city folk dwellers that drove them loop de loo fancy automobiles and not horse and buggy like farmer Teed.

All farmers & their family would celebrate every Thanksgiving and eat a batch of organic shingles. Some mysteriously died a week later but superstitions gave way later to science. This was all hushed up until Betty and John free spirit went public.

The Silencing of the spam…The whole mess was silenced with Betty and John free spirit getting a handsome some or money from the government, which latter they found out was the nice famer that got them into organic shingle farming in the first place. Mr. Teed.

An agreement signed and the two silenced.
So the government stopped making Organic shingles and farmers are happy they did.
Fairies now mostly visit young children exchanging teeth for money.
Fairies love smoking first growth teeth. It makes them do loop de loo’s.

True Robert, I don’t think there are a lot of animals out there that can digest petroleum products.
