- If you're experiencing any roof issues
or you just wanna educate yourself for the future,
then chances are
differentiating when a roof is improperly installed
compared to other issues,
is probably at the top of your mind.
Today, that's exactly what we're gonna be talking about
to see if you need to cash in your workmanship warranty.

Let's jump in.
(upbeat music)
Sliding shingles.
This is exactly what it sounds like.
If shingles are sliding down your roof,
and they're out of place,
then chances are they were improperly installed.
Now, there are exceptions to this.
The margin for error gets slimmer and slimmer
the steeper of a pitch your roof gets.
And when you get to a mansard roof,
or a 90 degree angle roof,
then sometimes even if it was nailed perfectly,
the shingles can still slide
just because of elements outside of the roofer's control.
However, if it's not a mansard roof,
then chances are it was improperly installed.
Poor attic ventilation.
Anytime your attic isn't properly ventilated,
your roof is not going to last its full lifespan, period.
Now, the way you can tell this is by going into your attic,
and if it's way, way to abnormally hot in the summer,
or if your decking is sweating,
that is condensation is forming on it,
and it's starting to rot, that's a telltale sign
that your attic is not properly ventilated,
and that needs to be fixed.
If you don't see any direct damage,
a good way to test your attic ventilation
is if you have a hot day and a cold night,
and the temperature changes fast,
then count about an hour after the temperature changes
to the cold part of the night and go in your attic.
If it's still hot like it was in the day,
it's not properly ventilated.
But if it's cooled down considerably
to match the outside temperature,
then it's properly ventilated.
Now, a reputable roofer, if they notice that your attic
isn't gonna be properly ventilated,
they'll at least try to give you a warning before anything.
Now, you're free to deny that.
But if the roofer has never even mentioned anything
about poor addict ventilation,
and you're experiencing just that,
then it was definitely an oversight
on the roofer's part,
or even worse, they just didn't care.
Popped nails.
The two main things that a contractor needs to get right
in order to properly drive a nail into your roof
is to hit it at the right angle
where it's straight on the roof.
And to make sure
they use the appropriate amount of pressure.
A method used much more subtlety nowadays
but used to be used all the time
is manually driving in nails with a hammer.
You're much less likely
to experience errors with this method
because every nail has to be done manually
and with proper care.
The second method is air guns.
That's used much more commonly today,
and the installers have to set
the appropriate amount of pressure for the nails,
else they risk over driving or under driving each nail
that they drive in.
Now, where there being hundreds and hundreds of nails
installed into even smaller roof systems,
there's bound to be a couple problems.
However, if you're experiencing
a ton of the same type of nail issue
and under or over driven nail,
then that means the air gun wasn't calibrated properly,
which is an installation error.
Bad weather conditions.
This is the simplest one to spot.
If your roof is ever being installed
in the rain or the snow,
it's going to have problems, period.
No contractor worth their salt should by any means
ever install it, even if it's just a light rain outside.
Something not as dire but still important to consider
is the temperature outside.
Not only for the health and safety
of the crew installing the roof,
but for the materials themselves.
In extreme temperatures, they'll break and crack much easier
than at a moderate temperature.
This used to actually be standard for shingle manufacturers.
Under the manufacturer's instructions,
it required them to be installed under certain temperatures
or else it would be considered an improper installation.
Now, for most manufacturers, that's not the case anymore.
However, the materials are still liable to break
if they're installed in cold temperatures.
For reference,
the ideal temperature to install roof shingles
is somewhere between 32 and 85 degrees Fahrenheit,
or zero and 32 degrees Celsius.
Common problems not caused by improper installation.
Now, there are also some very common roof issues
that some people can mistake for improper installation,
but actually aren't.
Some of those popular issues include,
granule loss,
shingles tearing off,
and two big ones are
leaks coming in through mortar joints in your chimneys,
or leaks happening around windows.
Now, most of these signs are problem based,
meaning you're not gonna notice them
until they actually start becoming a problem.
So if you just want that peace of mind to make sure
that your roof was installed properly,
you can always hire a good and reputable roofing contractor
to inspect the roof
and ensure that the quality is up to par.
