Speaker 1 (00:00):
KFI AM six forty. You're listening to Dean Sharp the
House Whisper on demand on the Ihearted Radio app. We're
talking about roofs, because if your roof is in bad
shape or in need of being fixed or changed or replaced,
now is the time to start working on that before
(00:21):
the heavy rains that are predicted for this El Nino
season end up showing up. You do not want to
wait till the last minute. Not saying that you can't
get you your roof done at the last minute before
the rainy season starts, but it's going to cost you more.
And so the wise homeowner is dealing with their roof
issues now here, even in late spring, as opposed to
(00:45):
waiting till the fall. And so we're talking roofs today
just so you can get a head start on all
of that. Also, we're about to go to the phone,
so just hang on for a second. But I do
want to mention this if your home needs some personal
house Whisper attention. If you're listening to the show and
you're thinking, you know what we really need. I love
(01:06):
to listen to this guy's advice, but we just need them.
If he saw the mess that we're dealing with here,
he would sing a different tune. No, I wouldn't, actually
not at all. But the point is this, you can
have some more personal house Whisper attention. You can book
an in home design consult with me and the tea.
All you have to do is go to house whisperer
(01:28):
dot Design for more info house Whisper dot Design, and
before you know it, we will be standing in your
name of troubled space inserted here, helping you figure out
the path toward making it extraordinary, I promise. Okay, all right,
it's time to go to the phones. Let's talk to Natalie. Hey, Natalie,
(01:52):
welcome home.
Speaker 2 (01:53):
Yeah, hi, thank you for taking my phone call. We
hired a contractor to put in a vinyl retrofit double
pain sliding door. The problem we have is that we
can hear a low frequency pitch. We had the contractor
return and they recocked everything very well. We live relatively
(02:16):
close to a freeway. It's most prevalent at night, whereas
during the day there are other noises that seem to
wash it out. Is there anything we can do about
this problem?
Speaker 3 (02:30):
Maybe? Maybe?
Speaker 1 (02:32):
And uh, okay, so brand new door. We've already resolved
So if we're doing diagnosis here, we've already resolved the
idea that maybe there were gaps between the slider and
the wall. That's all been caked and sealed and done
in my thinking, And you might think, Okay, what's he
going to say about this one? In my thinking, that
(02:54):
probably leaves one culprit left. And it's a pretty easy
diagnosis if it is in fact this culprit. Okay, Now
I'm going to assume it's a brand new sliding door,
and I'm gonna assume that the door itself is sealed.
Speaker 3 (03:09):
Well.
Speaker 1 (03:09):
I don't mean just on the outside. I mean that
the one active panel slides and interlocks well with the
fixed panel and so that there's no air whistling through there.
But believe it or not, I've heard of this before,
We've encountered it before. It's not actually all that uncommon,
and it's what we call arrow acoustic resonance. What arrow
(03:33):
acoustic resonance almost certainly is probably what's going on with
your door. The door here's the good news, is not broken,
nor is the install ineffective. The door is behaving like
a giant whistle. Okay, so what's happening a sliding door
has an interior cavity in the frame. That's where the
(03:56):
track is right that the pocket that the panel sits in,
and there are a bunch of intentional gaps at the
bottom of that cavity that we call weepholes. They are
weepholes so that they're there for drainage and operational integrity
of the door. Those wheepholes are there so that if
(04:17):
water collects in any of the tracks, that that water
finds its way outside, that they don't just fill up
like a little bucket. Okay, those weepholes on some doors
in some locations, depending on how the wind or the
breeze moves across the openings at just the right speed
(04:37):
and just the right angle, you get this thing.
Speaker 3 (04:40):
I could remember the name. Okay, I do this right, Dean.
Speaker 1 (04:44):
I'm pretty sure it's called a gnome as the helm
Holtz resonance effect. Okay, I know it's a lot of
sciencey stuff, but it's the point is this. It's the
volume of the cavity down there, and it's the orifice
geometry of the weepholes that are essentially causing and they
(05:04):
always do cause a low frequency hum. And the whole
assembly seems to hum. It's basically this It's the same
physics as blowing across the top of a beer bottle,
and you get that, except it's a hum that is continuous, right,
And it's a hum on the scale of a door,
(05:25):
not a beer bottle.
Speaker 3 (05:27):
And that's why it.
Speaker 1 (05:28):
Likely shows up at certain wind directions and it disappears
in totally calm Mayer or when the wind shifts, okay,
or when the breeze shifts.
Speaker 3 (05:38):
Okay.
Speaker 1 (05:39):
So the way to diagnose this, to make sure is
locate the weepholes. And I'm not going to tell you
to plug them permanently. I just want you to. Okay,
it's not going to rain today, right, and it's not
going to rain tomorrow. So locate those weepholes at the
bottom of the doorframe, and you know, take a piece
(06:01):
of tape, a piece of masking tape or whatever, and
just tape over them. Okay, just for today, for today
and tonight. If I'm right, and if this is the
Helmholtz effect coming through those wheepholes, then that's simply I mean,
we're basically taking the flute and we're plugging up the
openings on the flute, and the flute is not going
(06:22):
to make any more music, okay, And so if I'm right,
it'll stop. And if that's the case, if it kills
it instantly, that's the diagnostic all right. Now, I don't
want you to permanently block the wheepholes. But here's the thing.
There's the things you can do. It's the fact that
the airflow over the track, moving linearly along the track
(06:44):
is blowing over those wheepholes just in their particular alignment.
That's making that. And so what we have to do
is we just have to on the outside of the
door where it doesn't matter, we have to do a
slight disruption of the airflow over the whelphole. That means
there is some manufacturers make little tiny little fins that
(07:05):
can be installed on the outside track right outside the wheephole,
just like a little barrier wall right in front of
the wheephole. Sometimes we fixed them ourselves by just putting
a little bit of bead of call right next to
the weak wheephole, so that the wind has to jump
up over that little bead of calk and it doesn't
pass over the wheephole like air passing over the holes
(07:27):
of a flute. And so Natalie, do that check it out.
If it stops, all you have is an instrumental, a
musical instrument problem to solve, and you can do that
by disrupting the airflow over the door.
Speaker 3 (07:42):
How's that.
Speaker 2 (07:44):
Thank you so much for the insformation.
Speaker 3 (07:47):
You are so very very welcome. All Right, everybody, we
got to go to break. When we come back, more
of your calls.
Speaker 4 (07:52):
You're listening to Home with Dean Sharp on demand from
KFI AM six forty.
Speaker 1 (07:59):
We're talking about our roofs today. But right now we're
mid show, which means we're taking calls, and I'm going
to go back to the phones. Let's talk to Monica.
Hey Monica, welcome home.
Speaker 5 (08:12):
Thanks for taking my call on I was suggested because
I have such a cold house, and that's the nineteen fifties,
that the family room, which is a little downstairs the
floor should be like lifted seven inches at least and
put insulation and then there's no het in there anymore.
(08:32):
I'm a little afraid that's going to ruin the integrity
or the look of the sound proof on the sliding door.
It's real nice now, but I'm just afraid after hearing
about flighting doors.
Speaker 6 (08:43):
But I just wonder it really makes florance. You know,
it's pretty cold from that room.
Speaker 7 (08:50):
Yeah.
Speaker 1 (08:50):
Okay, So so the living room, it's a nineteen fifties house,
and I'm assuming that.
Speaker 6 (08:57):
It's the family room.
Speaker 1 (08:58):
It's a family room, and it's it's on slab. It's
on slab. It's not a raised foundation. Yeah, it's on cement.
Speaker 3 (09:06):
Yeah.
Speaker 1 (09:06):
And and you've got a tile floor, so you've got
you know, the cement, the cold of the ground transmitting
through the cement and right up into that tile and
uh and it cools that room.
Speaker 3 (09:17):
Out large quite a bit, right.
Speaker 1 (09:19):
Okay, well yeah, uh So here's the thing I would
do if if you're committed to changing that vibe in
that room, then how big is the room by the.
Speaker 6 (09:31):
Way, by fifteen?
Speaker 1 (09:37):
Okay, all right, so it's it's a good sized room.
But it's not like crazy out of control. It's not
a basketball court.
Speaker 3 (09:42):
Right.
Speaker 1 (09:43):
Uh So here's the thing, if you're committed to, uh,
if you're committed to changing the vibe of that room
and you don't want it to be cold anymore, there's
actually a relatively simple solution that that you're already thinking
about pulling up the tile and doing something extreme like
raising the level of the floor and insulating under there
(10:05):
and all of that, and I applaud you for being
committed to that level. Here's the thing. If we're gonna
pull up the tile, then to me, it's a no brainer.
Pull up the tile and don't do anything about changing
floor levels. Don't mess with your walls, don't mess with anything.
I want to make a one eighth of an inch
(10:26):
change in the level of your floor. How's that sound.
Speaker 3 (10:29):
Okay.
Speaker 1 (10:30):
I want you to pull up the tile, and I
want you to lay down a electric radiant heat flooring
pad underneath that floor. Electric radiant heat pad. It's gonna
be an eighth of an inch thick. It's gonna go
all over the cont go go right to the concrete,
and then you're gonna reinstall or put new tile down,
(10:52):
whatever you want to put down in that living room,
and it's gonna raise the existing level of the floor
just the thickness of that pad. That's going to be
tied into a power supply that's, you know, running out
the electricity of your house. It doesn't take a lot
of electricity, and it'll be set to a little thermostatic
control in the room. And that family room, my friend
(11:15):
will become your favorite place to be in the house
on a cool day, because you will walk in there
on a cold day in your bare feet and the
floor will be warm under your feet. Radiant heat will
be coming up out of that floor and filtering its
(11:36):
way through the room, warming the sofas, warming the furniture,
and rising up past your body, and it won't be hot,
it won't be out of control. It's not a sauna
or anything like that. It's radiant floor heating is the
most lovely, most efficient, most energy efficient, most most comfortable
(11:59):
kind of heating that can never be done in a
residential space period. Okay, better than forest air heating, better
than wall heater, is better, better, better than everything, and
it solves the problem of a cold tile. We often
in a retrofit or a remodel will do it in
a bathroom because people are like, how do I make
(12:21):
my bathroom more luxurious. I'm like, well, if we're going
to retile that bathroom floor, let's make it a warm floor.
Never once in my career has anyone ever come back
to me and said, you know, it was a real
mistake putting in that radiant flooring. All they say is,
you know what the mistake was that I didn't do
it in the whole frickin' house.
Speaker 6 (12:39):
And the cost for the electricity versus like gas heat.
Speaker 1 (12:43):
Oh, the cost of the cost for the electricity is
it is such efficient heat. It is such a massively
efficient heat because it's putting it all over the room,
rising up across you as heat should. The cost for
electricity versus the gas will either be leus or a
wash less or what or a wash It'll either be
(13:06):
the same or less.
Speaker 5 (13:08):
Oh, that's good.
Speaker 6 (13:10):
And also a dean, I wanted to say that your sermon,
but after your after your class last week, fantastic. Oh yeah,
thank you.
Speaker 1 (13:22):
I'm very I'm very, very touched when people enjoy the
closing thought at the end.
Speaker 3 (13:28):
Of the show.
Speaker 6 (13:30):
It's wonderful. Thank you so much, tean.
Speaker 3 (13:33):
You are so welcome, and so investigate that.
Speaker 1 (13:36):
And to just go ahead and do a Google search
for for uh electric uh uh you know floor heating
layers under that go underneath the level floors, and uh
you'll find them and you'll see how well they work.
And you know what, you're not going to regret it.
You're going to love it. You're gonna love it. And
(13:57):
it solves the problem just right on the nose. All right,
y'all when we come back, more of your calls your
Home with Dean Sharp, the house Whisper.
Speaker 4 (14:11):
You're listening to Home with Dean Sharp on demand from
KFI AM six forty.
Speaker 1 (14:17):
We're talking roofs today, but right now we're in mid show,
which means we are taking calls and we'll return to
our conversations on roofs at the top of the hour.
So I'm going to get back to the phones. Let's
see here, let's talk to Mike. Hey, Mike, welcome home.
Speaker 8 (14:39):
Hello, you said, Mike, right, I did?
Speaker 3 (14:42):
I did? How you doing?
Speaker 5 (14:44):
Hi?
Speaker 8 (14:44):
So I got an estimate for thirty nine dollars for
soybean oil roof rejuvenator, and my roof has been on
for twenty five fifteen years. It's a forty year moof.
The guy said, it looks like it's good for can
but yeah, you should get it quoted. And it's only
good for five years, and then we've got to come
back and quote it again. I mean, it's going to
(15:06):
be more than you know, sixty nine hundred dollars by
five more years. And I'm just wondering, is this a scam.
I can't really find much online about it.
Speaker 1 (15:17):
It's not a scam, but I want to be really clear,
Uh it is is so Okay, the technology, the concept
is not a scam. The uh, the and I don't
want to mention any uh don't. You don't need to
mention any brand names today. I'm going to mention one,
but I don't need to.
Speaker 3 (15:36):
You don't need to mention any but uh.
Speaker 1 (15:39):
But there are a lot of franchise business out there
that that don't necessarily apply it ethically, okay.
Speaker 5 (15:49):
Uh.
Speaker 1 (15:49):
In other words, they're just out to make the money
and so. And basically what it comes down to is
that the the it might get pushed on you on
your roof before you actually need it. Okay, So you
said you've got a forty year roof, and how old
is it now?
Speaker 3 (16:07):
Fifteen fifteen?
Speaker 1 (16:09):
So you're not even you know, you're you're basically halfway
into the life span of your roof. Are there is
any evidence whatsoever on your roof that it's starting to fail?
Is it curling? Is it letting go of granules in
an extreme amount?
Speaker 8 (16:28):
Well, not an extreme I think it's probably regular granule
lusage on a heavy rain. But it just I don't know.
I just thought, you know, what can it hurt to
get an expert in here to say, you know, how
is my roof? And he did say it's good for
ten more years, you know, but yeah you need the
code on there.
Speaker 3 (16:44):
Yeah.
Speaker 8 (16:44):
Yeah, So that's gould take them, you know, for four
thousand square feet. He said, it take them a little
over two hours. And I'm like, that's a lot of
money for two hours spraying.
Speaker 1 (16:54):
It is a lot of money for two hours spry
and so all right, so again I don't know. You know,
the company that I have recommended the most here on
the program is roof Max, Roof maa XX. I don't
know if that's the company that quoted you.
Speaker 8 (17:11):
But I'll just say no, but I won't say who.
Speaker 1 (17:14):
Okay, So so I would call them if you if
you have a question about it, because it's not just
the technology, it's not just the spray. It's the fact
that these companies come in way too early, okay. And
that's my opinion on your roof is that it's just
too early. You got a forty year warranty, roof, it
hasn't damaged. You're only you know, fifteen years into it
(17:37):
and could it, you know, benefit from a little moisturization. Sure,
but you know, and if you got the money to
spend on it, oh okay, fine. But the point is
you have at least another ten plus years out of
that roof before I would consider doing the soybean moisturization
(17:57):
or the the you know, the for it, because the
real point of coming in and using the moisturization product.
And they're they're completely legit, well some of them. Some
of them are a little nasty and caustic, but like
the one that roof max uses is the most proven one. Uh,
they're very legit. They'll take a curling tile and make
it calm down and lay down. They'll re refresh that
(18:21):
asphalt embedded fiberglass paper and it is it's legitimately. I mean,
we've seen it happen and I've recommended it. You can
get another five years extension out of the life of
that roof. And then sometimes you do it again, you
can get another five years out of it, but not
if you're applying not if you're applying it mid life span.
(18:41):
The idea is that we want to take an aged
roof that's nearing the end of its its usefulness and
kick the can of a reroof another five plus years
down the road. We're not trying to do it right
in the middle.
Speaker 3 (18:58):
Right.
Speaker 1 (18:58):
So it's it's like, you know, you know, I don't
want to give a you know, a twenty year old
a face lift. Okay, that's that's not the time. If
I don't know, I'm not saying there is a time
for a facelift. But I'll tell you this, it's definitely
not a twenty year old, okay. And so your roof
is young still, it's not even middle aged yet. And again,
(19:19):
if it hasn't been damaged or if it's for some reason,
it's not prematurely uh, you know, messing up on you.
I don't think it's you're anywhere near time to talk
about having you.
Speaker 8 (19:31):
I go up there often, you know, I clean up
my gutters, I wash my my solar panels, and there
is no curling like you suggest that I didn't. I didn't.
I'm not a roofer, so I don't really know what
all to look out for. But those few things that
you mentioned, yeah, I don't have those issues.
Speaker 3 (19:45):
Yeah, you've got to guess if you're.
Speaker 1 (19:47):
Too early, if you've got a shingle. That is a
forty year warranty shingle. All right, then fifteen years is
not the time to think about, you know, revitalizing the roof.
Its just it's just an that is an unneess serie expense.
The day will come when it might be a really
really good idea to you know, take a supplement to
(20:09):
lose what is that the roof doesn't have anymore?
Speaker 3 (20:11):
But it is not today.
Speaker 8 (20:13):
Gotcha, Thank you very much, very much.
Speaker 1 (20:16):
You are very very welcome, my friend. Really good question,
really good call. Can I squeeze one more in here?
Let's let's talk to Rick. Hey, Rick, welcome home.
Speaker 7 (20:26):
Hell indeed, I live up in the hills where there's
a fire zone and high winds. Maybe once a month
or sorry, one month a year. I'm putting on the
old house to story. I'm putting a new group, and
I want to be tile and I really like to
talk about vented addicts and nice. But I got a
little worried when they when they the spray installation, it
(20:47):
can trap moisture. And so my thought is, what if
I had a roof for absolutely no openings, all the venting,
without the side of the side of the house and
no nail holes, and it would be spray. It would
be the spray foam that would hold down the tile
and so there'd be no chance that any moisture could
get through. So tell me what you think of that.
Speaker 1 (21:08):
Well, okay, so we are we talking about Spanish tile roof, Yes, okayish, Yeah,
the actual You know a lot of people will be
surprised by this, but the the the dominant modern method
for applying. Uh, you know that the high end way
of applying a Spanish tile roof is not to use nails.
(21:30):
Nails have always been a little bit problematic for us
when it comes to a Spanish tile roof, and now
some roofers are going to have different opinions about this,
especially guys who aren't you know who who aren't educated
and or familiar with this. But a two part polyurethane foam,
polyset pro bond, tile bond foam are the common trade
(21:52):
names of it. You put bead pattern down on the
underlayment or on the tile below, and then the tile
gets that into it and the foam cures in a
few minutes and it creates a structural bond that, by
the way, not only is better than the nail, but
it's got a better wind uplift rating than nails.
Speaker 3 (22:11):
Right.
Speaker 1 (22:12):
It's actually to just give you some peace of mind
on it. In Miami Dade County, Florida building code that
has some of the most punishing wind standards in the country.
It's actually the preferred recommended method for installing Spanish tile
roofs is the foam system, so you're not penetrating the
(22:35):
underlayment and you're setting them in place. It actually harkens
back to the original design of Spanish tile roofs. You
know what, I want to comment on this a little
bit more so people can understand it better. So Rick,
you hang tight. We're going to go to break and
when we come back, I will finish this explanation about
putting in a Spanish tile roof without nails. Your Home
(22:57):
with Dean Sharp the House Whisky.
Speaker 4 (23:00):
You're listening to Home with Dean Sharp on demand from
KFI AM six forty.
Speaker 1 (23:08):
Here to remind you your home deserves great designed why
because you live there. You live there, and if it
is home for you, then it may be time, after
all the years of you getting out of its way,
for it to get out of your way and to
become more tailored to you, to your life, and so on.
(23:29):
My opinion about what makes a truly great home is
one that both expresses and blesses the life of its inhabitants. Okay,
just let that sink in for a second. It needs
to express your life and bless your life. It needs
to serve you and also project the very very best
(23:50):
parts of who you are. And there you go. That's
our goal. That's our goal here every week to help
you with that home. Right now, we're taking calls now,
I'm I don't know if it was us or him,
but we we lost our caller that I tried to
put on hold. But I want to finish answering this question.
He had called in and is wanting to do a
(24:15):
roof on his house that is a Spanish tile and asked, Hey,
can we just avoid the nails all together? Can I
use some kind of you know, polyurethane to connect the
tiles down, the Spanish tiles down, and put you know,
vents on the side, and not worry about the top vent.
I don't really care about the top vent I carried.
(24:37):
I'm concerned about adequate venting near the top of the roof.
I would say that a top vent is always a
great idea and always my preferred generally speaking, when you
can do it and visually it doesn't change the appearance
of the roof. But if you want to do if
you've got big gables on the side of each of
your roof and you've got enough room for adequate venting,
(24:59):
there great. And the idea of a roof that doesn't
have any penetrations in it whatsoever. Now that's unlikely, of course,
because there's always roof vents coming up through plumbing vents
coming up through the roof, and water heater vents and
kitchen fan vents. All that kind of stuff has to
(25:19):
find its way up through roof chimneys. But if you
want to minimize the penetrations and a roof, why not.
And the thing that I think probably arrested most people
about my answer was that, yeah, it's probably best. The
best modern application of a Spanish style roof is to
not put nails through it. Nails have always been tough.
(25:40):
You got this hollow material that is brittle to start with,
and you're trying to affix it with a nail, and
that nail is going to be make a penetration through
the underlayment, which I've already told you is a critical
waterproofing component and which all roofing nails do, by the way,
but Spanish tile roof there's just a lot.
Speaker 3 (26:01):
It's a big.
Speaker 1 (26:02):
Nail, and there's a lot of leeway around it, and
most importantly, in high wind conditions, those tiles can lift
up and the roof nail doesn't do that great of
a job holding it down, which is why I was
saying that in Miami Dade County, because of hurricane code conditions,
they've actually kind of spearheaded the use of polyset pro
(26:27):
bond tile bond, you know, polyurethane foam as the means
of attaching it down. And that should, by the way,
you know, resolve any questions you have whatsoever of how well,
of how good of an attachment.
Speaker 7 (26:42):
That is.
Speaker 1 (26:43):
Okay, that's what you do when hurricanes may be an
issue for your roof is you use the foam set
systems for high velocity hurricane zone. So that tells you
all you need to know about the holding power of
polyurethane phone on Spanish tile. But I was gonna say
the last thing I wanted to add was that actually
(27:04):
harkens back to the original way of attaching a Spanish
tile roof, which just simply used to be There're no
nails were involved originally in Roman tile roofs and Spanish
tile roofs. They were simply set with the stickiness of mortar.
Which if you really want a roof to look like
(27:25):
it's old, like a brand new loof, there's nothing better
for a Spanish tile roof than to spend some extra
money and actually put a little bit of mortar bed
up underneath the front of each tile. Talk about just
instantly aging. You'd take a brand spanking new roof and
make it look like it's been there, not in a
(27:46):
decrepit way, in the most beautifully aged way, make it
look like it's, you know, two hundred years old and
hundreds of years. These roofs last with the right mortar bond. Now,
of course, eventually the tile slips, cause concrete more only
has so much adhesive power to it. But the new
polyurethane foams, that's a totally different story. That is a
(28:07):
glue downed roof, all right, that's a hurricane proof roof.
So yes, it is actually preferred these days. If you're
thinking about reroofing and you've got Spanish tile, it's preferred
these days to use polyurethane foam instead of nails. And
it's really not about the penetration through the underlayment. Because
(28:27):
the underlayment that I want you to use on all
of your roofs, take note, is a a self sealing,
self sticking, self healing membrane. Okay, a rubberized flexible membrane
that goes down, seals onto itself each course, so that
by the time you're done, you have one single uniform
(28:50):
membrane and then as roofing nails go through it, these
soft rubberized asphalt membrane seal around the nails. They self
seal around penetration, so they are the best thing that
you can do. Grace fire and ice, high heat membrane.
Check that out online. That's the kind of stuff that
I'm talking about that is just absolutely brilliant, brilliant for
(29:11):
moisture and the coldest, wettest, snowiest, iciest environments, good for
the hottest possible weather out in desert environments and everything
in between. So that underlayment is key, and yeah, using
polyurethane to see it all down is good is good?
Speaker 3 (29:29):
All right?
