Performing a Roof Inspection with Russ Ackerman CMI®

Hi. My name is Russ Ackerman. I'm a Certified Master Inspector through

InterNACHI. I'm here to do a roof inspection. Today we're going to cover a typical

inspection of a roof from the exterior. My roof inspection starts from the

ground. As I'm as I'm inspecting the exterior of the home, I'll usually start

by documenting attic ventilation which might not otherwise be visible from the

roof that would include gable and soffit vents. So I'm going to walk around the

house now and try to look for those and here in the side of the house we can see

we have a gable bent so I'm going to take a picture and document that on my

report when I set up my ladder I typically look for a place where I got a

nice flat surface to set the ladder anytime you're setting up the ladders I

always want to look for wasps nests that might be around always looking for

overhead power lines as well as you get up in the ladder we're always going to

tie off our butt ladders with a bungee cord as you see up there I always want

to keep your ladder tied once we get up at the gutter line I usually want to

check for any drip edge flashing that might be here this one does not have any

because the gutter is serving as the drip flashing or gently pull up on the

shingles I can see that there's underlayment going over the flashing

make this sure to bond it down it's not the wind is not going to take and pull

it up once we're on the roof here I'm going to continue looking for attic

ventilation so I'm going to be looking for a roof vents will go overlooked for

that here we can see we have roof vents for the Attic so I'm going to talking

about that take a picture of that make sure all the nails are sealed down as

well next we take some overview shots of the roof I always like to make my

pictures look great so if I have a mountain view versus another house I'm

going to take the mountain view so I'll go over here and take a couple photos

and I'll take some photos some more overview shots and I'll get one overview

of justice ingles in general and then as we were looking over the conditional

roof I am seeing some granule laws I'll go over look for exposed nails the

flashings this is all sealed up good you come over here we have some exposed

nails at the ridge line here so I make sure those are all set and sealed

they're popping out get over here you can see one exposed nail some granule

law so the Hale kind of hits sometimes it shows up on the ridge shingles versus

the rest of the roof plane and as we get to the valleys I want to check to make

sure they're properly bonded and we want to these shingles sealed against cross

wash so the water doesn't wash over and under so I'll give a little Cub going

down the valley just to make sure they sealed and these are pretty good

these are sealed pretty well also in order to document other flashing around

that roof besides a drip edge flashing any roof penetrations I always want to

document those look making sure they're properly installed make us your nails

are sealed take pictures of everything document everything because this is a

area that the client is not going to follow you up on the roof your HVAC vent

over here as well check again for flashing issues exposed nails want to

make sure there's no cracks in the bed here which might allow water that's

actually drain and back into the furnace you come around here you can see some

nails popping up the flashing is popping up you got a big gap here on make sure

this one have a roofer come in here seal these nails seal that flashing back down

same with the skylight here as well got the flashing popping up wanna have that

secured and nailed

here you can see over the sunroom in the back of the house there there's still

asphalt shingles but it's definitely newer it's been installed recently the

owner actually said it was 1/2 years old I put it on my report one to five years

old so we're to check that out first thing I noticed is some flashing issues

where this addition is going against the original roof kind of hard to see here

but I'll take some pictures there's a metal flashing and then they just have

it covered with tar paper which is a indication this things might have had

leaking problems at at one point this plastic is improperly installed on top

of the singles should be like a counter flashing installed here so I did take a

couple pictures and document that we recommend evaluation repair by a

qualified roofer potential leaking point here that's an issue

continuing with flashing down here you can see on the lower roof they have

actually a piece of wood glued to the chimney or talked to the chimney working

as a counter flash and that's improper install but the counter flashing should

be going into the motor joints of the chimney which it's not this is a

potential issue it's something I would recommend the sellers to caulk or the

buyers to have them check the seals make sure this is sealed annually or replace

by a qualified roofer also at the bottom of this flashing that we're looking at

right now you can see we're missing a kick-out flashing where the flashing

ends at the gutter line there that's going to allow water to just pour down

along the side of the chimney we want to have a proper kick-out flashing

installed there as well on this roof surface you can see that there's a

broken there's a low sluice missing tab here on the roof and I recommend having

that checked out replaced by a qualified roofer and then we'll check out the last

portion of the roof which is this rolled asphalt valley towards the front of the

house we'll go check that out right now here we have a little rolled asphalt in

this valley here you can see there's a lot of granule loss there's a lot of

cracking this foot this portion of the roof is at or near the end of its

lifespan I'm going to recommend having this evaluated replaced by a qualified

roofer here we have tree branches in contact with a roof surface and several

I always recommend trimming trees at least 10 feet away from the roof surface

that's not always possible but we just don't want them when they're blown in

the wind we don't want to be causing abrasion against the shingles against

the fascia so we're going to recommend having these trim back over here we have

more tree branches close to the roof surface going to recommend trimming

those back and on the back of the house as well

you see tree branches in contact with the North corner of the home then we're

going to look at the skylights we're looking for proper flashing at the head

wall flashing the counter flashing the apron flashing everything looks pretty

good here again we made note earlier that the flashing was curling up at the

corners here on both these corners would recommend having be sealed secured down

also if you look at all three skylights there's condensation moisture between

the glass and all three of them these are all failed window seals I'm going to

recommend replacing all three of these skylights right here and down here you

can see it's all fogged up that's just going to continue to fog up more and

it's going to be you won't even be able to see all of them eventually and here

you can see the moisture it's in between the panes of glass once you get inside

the house we're not going to do that today but once we get inside the house

you're going to want to check closely for any moisture stains on the insides

of these skylights if they're already you want to confirm it with a moisture

meter make sure it's not an active leak either way you would put in your report

that evidence of past leaking recommend repaired by a qualified roofer last

thing on the roof is the plumbing weather boots I want to make sure that

weather boots are intact they're not all cracked up a lot of times it will be on

older homes allowing water penetration in the Attic again well makes your nails

are sealed up if you find these all bleeped up with tar that's indication

that they've been leaking and they need to be replaced by a qualified roofer

these are in good shape though the chimney is normally part of my exterior

inspection but because there are roof flashing who stuff we'll do a quickie on

here we did notice it's a 60-inch wide chimney so we want to make sure we have

some kind of cricket or flashing at the head of the chimneys keep water from

pouring against it which it does a couple things I'm noting here is the

flashing improperly installed here should be inserted into the motor joints

there should be a groove cut inserted into the motor joints these are just

slapped up against the chimney cocked that's going to wear out eventually

cause leakage that's something I'm going to recommend sealing annually until we

have proper flashing installed also we'll notice there's a lot of loose

missing mortar at the joints these are water penetration these are potential

water entry points as rain can get down inside the chimney chase you'll see a

lot of that here and all over the side of the chimney here as well there's a

lots of gaps in the mortar I'm going to recommend having that tuck pointed

sealed up properly getting the side of the chimney again you've got a piece of

wood kind of like we head down below you know a piece of wood caulk to the

chimney serving as a counter flashing this is not a proper installation we do

have proper step flashing underneath but we going to recommend having proper

counter flashing installed otherwise this is going to need sealing annually

to prevent water entry and as we continued with our roof inspection over

the main house we did notice one nail pop on the on the roof here it wasn't

set properly it was actually it was actually set where it was supposed to be

just wasn't sunk down all the way so I don't have that secured make sure this

is sealed down so we don't have nailed poking through the top of the shingle

later on and this concludes our inspection of the exterior portion of

the roof thank you for watching
