Performing a Roof Inspection with Russ Ackerman CMI庐 - YouTube

Hi. My name is Russ Ackerman. I'm a
Certified Master Inspector through
[10]
InterNACHI. I'm here to do a roof inspection. Today we're going to cover a typical
[15]
inspection of a roof from the exterior. My roof inspection starts from the
[18]
ground. As I'm as I'm inspecting the
exterior of the home, I'll usually start
[23]
by documenting attic ventilation which
might not otherwise be visible from the
[28]
roof that would include gable and soffit
vents. So I'm going to walk around the
[32]
house now and try to look for those and
here in the side of the house we can see
[36]
we have a gable bent so I'm going to
take a picture and document that on my
[39]
report when I set up my ladder I
typically look for a place where I got a
[43]
nice flat surface to set the ladder
anytime you're setting up the ladders I
[47]
always want to look for wasps nests that
might be around always looking for
[50]
overhead power lines as well as you get
up in the ladder we're always going to
[53]
tie off our butt ladders with a bungee
cord as you see up there I always want
[58]
to keep your ladder tied once we get up
at the gutter line I usually want to
[62]
check for any drip edge flashing that
might be here this one does not have any
[65]
because the gutter is serving as the
drip flashing or gently pull up on the
[69]
shingles I can see that there's
underlayment going over the flashing
[72]
make this sure to bond it down it's not
the wind is not going to take and pull
[75]
it up once we're on the roof here I'm
going to continue looking for attic
[80]
ventilation so I'm going to be looking
for a roof vents will go overlooked for
[83]
that here we can see we have roof vents
for the Attic so I'm going to talking
[90]
about that take a picture of that make
sure all the nails are sealed down as
[95]
well next we take some overview shots of
the roof I always like to make my
[99]
pictures look great so if I have a
mountain view versus another house I'm
[102]
going to take the mountain view so I'll
go over here and take a couple photos
[112]
and I'll take some photos some more
overview shots and I'll get one overview
[120]
of justice ingles in general and then as
we were looking over the conditional
[124]
roof I am seeing some granule laws I'll
go over look for exposed nails the
[129]
flashings this is all sealed up good you
come over here we have some exposed
[135]
nails at the ridge line here so I make
sure those are all set and sealed
[140]
they're popping out get over here you
can see one exposed nail some granule
[146]
law so the Hale kind of hits sometimes
it shows up on the ridge shingles versus
[150]
the rest of the roof plane and as we get
to the valleys I want to check to make
[153]
sure they're properly bonded and we want
to these shingles sealed against cross
[157]
wash so the water doesn't wash over and
under so I'll give a little Cub going
[162]
down the valley just to make sure they
sealed and these are pretty good
[166]
these are sealed pretty well also in
order to document other flashing around
[171]
that roof besides a drip edge flashing
any roof penetrations I always want to
[175]
document those look making sure they're
properly installed make us your nails
[179]
are sealed take pictures of everything
document everything because this is a
[183]
area that the client is not going to
follow you up on the roof your HVAC vent
[189]
over here as well check again for
flashing issues exposed nails want to
[195]
make sure there's no cracks in the bed
here which might allow water that's
[198]
actually drain and back into the furnace
you come around here you can see some
[203]
nails popping up the flashing is popping
up you got a big gap here on make sure
[207]
this one have a roofer come in here seal
these nails seal that flashing back down
[212]
same with the skylight here as well got
the flashing popping up wanna have that
[217]
secured and nailed
[222]
here you can see over the sunroom in the
back of the house there there's still
[226]
asphalt shingles but it's definitely
newer it's been installed recently the
[230]
owner actually said it was 1/2 years old
I put it on my report one to five years
[234]
old so we're to check that out first
thing I noticed is some flashing issues
[239]
where this addition is going against the
original roof kind of hard to see here
[245]
but I'll take some pictures there's a
metal flashing and then they just have
[249]
it covered with tar paper which is a
indication this things might have had
[254]
leaking problems at at one point this
plastic is improperly installed on top
[258]
of the singles should be like a counter
flashing installed here so I did take a
[263]
couple pictures and document that we
recommend evaluation repair by a
[270]
qualified roofer potential leaking point
here that's an issue
[275]
continuing with flashing down here you
can see on the lower roof they have
[283]
actually a piece of wood glued to the
chimney or talked to the chimney working
[287]
as a counter flash and that's improper
install but the counter flashing should
[292]
be going into the motor joints of the
chimney which it's not this is a
[295]
potential issue it's something I would
recommend the sellers to caulk or the
[299]
buyers to have them check the seals make
sure this is sealed annually or replace
[304]
by a qualified roofer also at the bottom
of this flashing that we're looking at
[309]
right now you can see we're missing a
kick-out flashing where the flashing
[313]
ends at the gutter line there that's
going to allow water to just pour down
[316]
along the side of the chimney we want to
have a proper kick-out flashing
[319]
installed there as well on this roof
surface you can see that there's a
[325]
broken there's a low sluice missing tab
here on the roof and I recommend having
[330]
that checked out replaced by a qualified
roofer and then we'll check out the last
[334]
portion of the roof which is this rolled
asphalt valley towards the front of the
[338]
house we'll go check that out right now
here we have a little rolled asphalt in
[342]
this valley here you can see there's a
lot of granule loss there's a lot of
[345]
cracking this foot this portion of the
roof is at or near the end of its
[348]
lifespan I'm going to recommend having
this evaluated replaced by a qualified
[352]
roofer here we have tree branches in
contact with a roof surface and several
[356]
I always recommend trimming trees at
least 10 feet away from the roof surface
[360]
that's not always possible but we just
don't want them when they're blown in
[363]
the wind we don't want to be causing
abrasion against the shingles against
[366]
the fascia so we're going to recommend
having these trim back over here we have
[370]
more tree branches close to the roof
surface going to recommend trimming
[373]
those back and on the back of the house
as well
[378]
you see tree branches in contact with
the North corner of the home then we're
[383]
going to look at the skylights we're
looking for proper flashing at the head
[387]
wall flashing the counter flashing the
apron flashing everything looks pretty
[390]
good here again we made note earlier
that the flashing was curling up at the
[396]
corners here on both these corners would
recommend having be sealed secured down
[400]
also if you look at all three skylights
there's condensation moisture between
[405]
the glass and all three of them these
are all failed window seals I'm going to
[409]
recommend replacing all three of these
skylights right here and down here you
[415]
can see it's all fogged up that's just
going to continue to fog up more and
[419]
it's going to be you won't even be able
to see all of them eventually and here
[423]
you can see the moisture it's in between
the panes of glass once you get inside
[429]
the house we're not going to do that
today but once we get inside the house
[432]
you're going to want to check closely
for any moisture stains on the insides
[436]
of these skylights if they're already
you want to confirm it with a moisture
[439]
meter make sure it's not an active leak
either way you would put in your report
[443]
that evidence of past leaking recommend
repaired by a qualified roofer last
[448]
thing on the roof is the plumbing
weather boots I want to make sure that
[451]
weather boots are intact they're not all
cracked up a lot of times it will be on
[454]
older homes allowing water penetration
in the Attic again well makes your nails
[458]
are sealed up if you find these all
bleeped up with tar that's indication
[462]
that they've been leaking and they need
to be replaced by a qualified roofer
[465]
these are in good shape though the
chimney is normally part of my exterior
[469]
inspection but because there are roof
flashing who stuff we'll do a quickie on
[473]
here we did notice it's a 60-inch wide
chimney so we want to make sure we have
[477]
some kind of cricket or flashing at the
head of the chimneys keep water from
[481]
pouring against it which it does a
couple things I'm noting here is the
[487]
flashing improperly installed here
should be inserted into the motor joints
[492]
there should be a groove cut inserted
into the motor joints these are just
[495]
slapped up against the chimney cocked
that's going to wear out eventually
[498]
cause leakage that's something I'm going
to recommend sealing annually until we
[503]
have proper flashing installed also
we'll notice there's a lot of loose
[507]
missing mortar at the joints these are
water penetration these are potential
[512]
water entry points as rain can get down
inside the chimney chase you'll see a
[516]
lot of that here and all over the side
of the chimney here as well there's a
[521]
lots of gaps in the mortar I'm going to
recommend having that tuck pointed
[524]
sealed up properly getting the side of
the chimney again you've got a piece of
[528]
wood kind of like we head down below you
know a piece of wood caulk to the
[531]
chimney serving as a counter flashing
this is not a proper installation we do
[535]
have proper step flashing underneath but
we going to recommend having proper
[539]
counter flashing installed otherwise
this is going to need sealing annually
[543]
to prevent water entry and as we
continued with our roof inspection over
[546]
the main house we did notice one nail
pop on the on the roof here it wasn't
[550]
set properly it was actually it was
actually set where it was supposed to be
[555]
just wasn't sunk down all the way so I
don't have that secured make sure this
[558]
is sealed down so we don't have nailed
poking through the top of the shingle
[562]
later on and this concludes our
inspection of the exterior portion of
[566]
the roof thank you for watching
