- Today on Q&A Mondays we talk
about metal roofing in hot weather climates.
(intense rock music)
What's up guys?
Welcome to the Metal Roofing Channel
and welcome back to Q&A Mondays.
I'm here in Dallas, Texas with Doug Markle
from Sheffield Metals.
Doug, thank you so much for being on the show today.
Really appreciate it.
- You bet.
Thank you for bringing the Metal Roofing Channel to Texas.
- Yeah, absolutely.
I'm excited to be here.
My first time in Texas and I've had a good time so far.
So first of all, can you tell me
a little bit about yourself?
Who you are and what you do here at Sheffield.
- Sure, again I'm Doug Markle with Sheffield Metals.
I'm the general manager of the Southwest Division.
I've been responsible for sales
for this area for, be 10 years in December.
- Okay, very nice.
So again, today we're talking about metal roofing
in a hot weather climate.
Here in Texas there's humid areas, gets very hot
most of the year round.
Tell me a little bit first, is metal roofing popular
in hot weather climates and why or why not?
- Absolutely, I think metal roofing is gaining
popularity regardless of climate,
but especially in hot climates.
You have products like acrylic coated Galvalume
that has high solar reflective indexes.
It bounces the heat back
off of the roof almost immediately.
In your WeatherXL and Kynar paint systems,
you have cool pigments in there that help
keep the surface temperature of the roof cooler.
The whole idea in metal roofing in warm weather climates
is to get that heat transferred off of the roof system.
Which in turn helps you not spend as much time and energy
lowering the temperature inside the house
and it helps you save on your energy costs.
- Exactly, and we're gonna talk about solar reflectance
SRI values a little bit later.
But first can you tell me about why does the durability
of metal roofing make sense for an area here like
Texas and Dallas area?
- If it's installed properly, standing seam metal roof
regardless of paint system,
should probably last you 50 or 60 years.
So you're really buying a lifetime roof system.
- Yeah.
- I think people are really drawn to that
because with your shingle, your asphalt shingle systems,
especially in an area like here,
you're probably looking at replacing your roof
every 8 to 10 years.
- Okay, yeah.
So I think one thing that people think about
when they think about metal is that metal holds heat.
Is that true with metal roofing or is that a myth?
- I think it's a myth.
It's probably going to be a warmer initial surface
temperature if you're up working on it.
But again like we talked about with the solar reflective
index and the emissivity properties
of metal and various paint systems,
whether it's bare metal or painted metal,
the aspects that you're looking for in a metal roof system
is something that's going to push back the heat
as it's coming down on there and with the paint systems,
again, we talked about lowering the surface
temperature of the roof.
So, it's a myth.
- And we've got a great video series going on right now,
Standing Seam Metal Roof Design,
where we talk about this exact topic,
cool roofing and how metal solar reflectance, emissivity,
all those different properties of metal roofing.
So, definitely check that out in the next couple of weeks.
So talk to me about UV exposure in a climate like this.
If someone has concerns that their roof
will have extreme fading, what would you say to that?
- I would say that is definitely a concern.
Especially in a state like Texas, where we probably average
310 to 320 plus days of sunshine a year.
I would advise that if you have concerns about UV exposure
and how your paint system is going to react
to all of that direct sunlight,
consult your roofing contractor
and make sure that they're installing a system
that is designed to be in that much direct light.
Something similar to a silicone modified polyester system
or a PVDF paint finish system.
- Yeah, great.
And we have a video about PVDF versus SMP.
Definitely, check that out as well.
So talk to me about what type of metal roofing system
should someone be looking for if they live
in an area like, Texas.
- Obviously, standing seam is very popular
in an area like Texas.
Can be done in steel or an aluminum substrate.
There are other metal roofing products out there.
Aluminum shingles, stone coated steel.
It's basically, it's gonna boil down to the aesthetic
that you're looking for.
The benefit with standing seam again, if installed properly,
the performance characteristics of it are off the charts.
You have superior paint systems on all of your colors.
And you have a variety of substrates.
If you're more inland, you would wanna go
with a steel substrate.
But however, if you're along the coast
you can get it in an aluminum substrate
which helps protect it against the exposure to saltwater.
- Yeah, that's a great point.
Let's talk about some other types of weather
that Texas experiences other than just heat.
- Absolutely, the other primary weather concern
that we have here in Texas is hail.
Your metal roofing systems are designed
to be hail impact resistant.
Number of panel profiles,
depending upon which one you go with,
have a class four hail impact resistance rating
from Underwriters Laboratories.
And we also have miles and miles of coastline in Texas.
So at various times of the year,
hurricanes and strong winds are a consideration as well.
Occasionally in the spring,
we are prone to tornadoes in parts of the state.
So again, you need to consult with your roofing contactor
and make sure you're choosing the correct metal roofing
system that is designed to protect your property.
Whether it's residential or commercial,
against any sort of adverse weather condition.
- Alright Doug, well, I really appreciate it.
I think we covered a lot here.
