Guess The Roof Shingle Age

[Marcel R. Cyr]

In the past, some made comments that they could guess the roof shingle age to within five years +/-, Well, here is one for you I was working on today.

How old would this one be?

[Bob Elliott]

15 plus
I just usually mention on something like that to replace but otherwise might mention in thirds of life span.
Looks like it was an easy climb at least.
What is that a manufactured home?

Bob, you scared the hell out of me with that Avatar

Nope, stick built. Got to inspect the attic tomorrow to see if I need to add ridge venting or advise on insulation and the regular stuff we normally do.
Do that for the client while I am working there.

I see so many older places without venting and no issues that I feel like a deal breaker telling them to spend money on adding vents .
Lets see now....insulation and no moisture barrier and wood looks fine after 50 years so dig it all up and add some.

15-18 years
Standard weight asphalt 3 tab
with tree cover
No curl visible from photos on the tab...
but
assume
shingles shaded and stay wet

I agree Bob, and I will take more pictures of this one on the venting that is existing and the attic tomorrow.

Good point, there are a lot of variables that affect the age and condition of roof shingles. The scientific data is not always correct in factual existing conditions. It is correct in theory.

My guess is 25 years

Trees are 50' away in two directions and 100' away in another Joe. Good guess though.

You're good Joe. Recognize the color-lok siding by masonite did you?
Let us see who can guess the age.
