John Maher: Hi, I'm John Maher, and I'm here today with Brett Rogenski, general manager of Master Roofers, the most trusted roofing company in New Hampshire for over 80 years. Today we're talking about roofing myths. Welcome, Brett.

Brett Rogenski: Hey, thank you, John. I appreciate you having me.

What are Some Common Myths Associated with Roofing?

Maher: Sure. So, Brett, what are some of the most common roofing myths that you encounter as a roofing professional?

Rogenski: Gosh, there's a lot of them. And you know what, we really don't blame homeowners for that because how many people really know much about roofing and the roof and how it went down. Most of us, a lot of us have never bought a roof in our lifetime, and I think the average consumer owner only ever buys one I think it's statistically the average. So yeah, we're all not roofing professionals. That's our job. That's why you work with a company like us.

So, I would tell you, the most prevalent myth is one, and you could say it goes back to estimation and shopping is, all roofs are the same, okay? If I'm thinking about a traditional home with a shingled roof, they're all pretty much the same. Just go with the cheap roof, right, because the materials… Shingles the shingle, what goes on under, isn't that the only thing up there, or what goes on under the shingle must all be the same?

And I guess why I would tell you, the biggest misconception is that, I guess I would tell you, it's not 1952 anymore. It's not tar paper under there and some asphalt shingles on top and away we go and is kind of all the same. Every manufacturer has different lines of shingles that are appropriate for different, number one, different types of surfaces, and also number two, different homeowner needs or desires. And then the really super important part is what's going on under the shingles as well. So, the assembly system, the things that are going to ensure that your attic and your home breathe and all those things.

So, a roof isn't just a roof and go with the cheap guy because they're all the same. That would be kind of like saying, well, just buy the cheapest used car that you can find because they're all the same. That's not quite true. There's a lot more to it than that.

Talk About Roofing Materials

Maher: So, can you talk a little bit about roofing materials and explain what types of roofing materials are available and whether they're suitable for various climates or different types of homes?

Rogenski: Sure. Yeah, I mean, I guess I would tell you, a roofing system kind of starts with what we call underlayments, which are the things that go between the roof and then the roofing material. There's a whole variety of different things there and different classes of them from being very inexpensive and not very good to being a little larger investment, but providing a different experience. The next thing that's typical to any roof is ice and water shield. So, ice shield in the northeast here, that's something that's very typical for us.

Then we get into what's going on top of it. Well, there's a lot of different options. There's asphalt shingles of which every manufacturer makes different grades. Some of them are less expensive because they're not as robust a product. Some of them are more. So, there's something for every budget. There's also, you can get away from that, you can get into slate. You can also get into standing seam metal.

So, there's a whole variety of different things. I would tell you, the most common by far is asphalt shingles. And asphalt shingles kind of break down into a couple of segments, largely it's what's called three-tab, which is kind of a standard old shingle that most of us saw. And then architectural shingles, which are actually a laminated product that's more robust. It also allows the manufacturer to do different things to make it, I guess I would tell you, make it look a little prettier as well. But so, asphalt shingles are definitely the most common that's going over, but everything has its place.

Slate is a wonderful product. Cedar is a wonderful product. It's just not appropriate for every situation. Standing seam metal is popular and becoming even more popular. A lot of times we see that on commercial structures, but people do that on their homes as well, especially in areas with heavy snow loads. One of the beauties of standing seam metal is it's essentially impermeable. You're going to put that roof up there, and 50 years from now, it should be as tight as it was the day that we put it on, as long as it hasn't been damaged and it was, of course, installed properly.

Another thing that people don't necessarily think about and they need to with roofing is ventilation. There's a whole second side to your roof. There's the side that we all see, which is the shingles or standing seam. Well, guess what? Go up in your attic, that's the other side of your roof is that plywood and all the other stuff. And proper ventilation, or better said, improper ventilation is number one potentially even dangerous for the homeowner because you can have mold, mildew, all these other things, but it's also detrimental to the life of the roof as well.

So again, that second side of the roof, the part that most of us don't think about up in the attic, if that attic is not properly ventilated through ridge vent or gable end vents, whichever we're doing, we do a lot of ridge vent, it's going to lessen the life of the roof and also be a worse experience for the customer potentially in terms of home health.

Is One Type of Roofing Material Better Than Others?

Maher: Okay. And so is one particular type of roofing material better for the climate here in New England than another, or do they all work pretty well?

Rogenski: I would tell you that they all have a proper place. It's kind of like anything. You just want to get the proper product, and sometimes there's more than one solution that's appropriate to a home. If you take money out of it, but let's face it, money is a real thing, if you take money out of it, there's a lot of options that can work on different homes, but most people don't want to pay significantly more for a roof to do it as a standing seam metal roof versus, say, an architectural shingle roof.

So, I would tell you, again, here in New England, by far the most common residential roof is an asphalt shingle roof that is architectural shingles, and there's a lot of really great products out there. Again, that can have warranties of up to 50 years if they're done by a certified contractor such as ourselves that they're willing to warrant that roof for up to 50 years on that product, which is really amazing.

Does the Color of Shingles Impact the Home?

Maher: Talking about myths, I know that some people believe that one color versus another color of shingles affects their home and maybe the energy efficiency of their home. Lighter roofs might reflect the sun more, so they might be better in the summer and not let as much heat in. But on the other hand, in the winter, darker shingles might allow more sun to hit the roof and warm up the home. Are lighter and darker shingles, does that actually affect the energy efficiency of your home? And if so, which one do we prefer generally here in New England?

Rogenski: Sure. You know what, in general, there's not actually a huge amount of difference. If you go back to that whole discussion that we had about ventilation, so if an attic or whatever the space beneath that roof is properly ventilated, there's not a lot of difference. Yes, a very dark shingle on a very sun exposed roof will build up some heat faster than a much lighter colored shingle on that same roof. But if that attic that is above those is properly ventilated, the difference is nominal, and it's really not lengthening or shortening the shingle life at this point.

That used to be true more so many years ago, but the manufacturers, especially when you're talking about architectural shingles, which are a laminated, multilayered product now. Old shingles used to be pretty much asphalt granules, a little bit of... there was like a matting in there, and they were more susceptible to heat damage. Current ones based on the color of the shingle, not so much. You're more likely to damage a roof of any type by having it being improperly vented. Now you're cooking it from the top, sunlight, and from the bottom, the inside. So if that attic space is not properly vented, you're going to do more damage than the difference between a light gray shingle and a dark black shingle That's going to be a lot different.

So as long as it's being installed properly, the difference is so marginal, I would tell you, it's not worth that. I tell homeowners, choose what you think would look really great, and in a case like us where we're going to ensure proper ventilation, hey, go with what makes you happy, what makes it look good to you, and you're not going to have a problem because we're going to ventilate that area properly.

Should Homeowners Inspect their Roofs Regularly?

Maher: Right. Most homeowners can probably go months or years without even hardly looking at their roof. Is that something that homeowners should be doing on a regular basis, inspecting their roofs or calling a professional to come in and inspect their roof and just make sure that it's in good shape? And if so, how often should they be doing that?

Rogenski: Sure. Great question. Yeah, you're right. Most homeowners, I would tell you, most homeowners have never been on the roof, nor do they want to, right?

Maher: Sure.

Rogenski: We all have different things that we do. So, Mr. Smith might be really great at something, but climbing up on his roof probably might not be his deal, and that's great. So yeah, I would tell you, if someone's capable and can safely perform an inspection of their roof, it's good to get up there and just give it a visual inspection every year or two years.

I would tell you, most homeowners, we really don't suggest that because they're not going to be able to do that in a safe manner. We don't want someone getting hurt going up and look at. So yeah, you can call a professional roofing company such as Master Roofers. There are also some home inspection companies that offer the service as well.

And I would tell you, if no one's been on your roof in five years, give a call, it's very inexpensive, and have someone come out and just take a look at that roof. And really at that point, if it's a newer roof... So, let's say you put it on five years ago, no one's been there since and that sort of thing, we're really looking for physical damage and proper installation. Are you having issues because it was not installed properly? Meaning do you have shingles breaking loose because they didn't use the nailing strip? What are you having going on there? We can help you with that. Did you suffer damage, a limb, hit your roof and you thought everything was fine, and it turns out it's not?

But we're happy to do those sort of things, and we're just as happy, and quite frankly, we're happiest when we can jump up there and go, "Yeah, everything looks awesome. Geeze, John, your roof, it looks like it's in great shape, it was installed well, and we see no damage unless something happens, give us a call again in five years." So that's really what we like to do.

But by the same token, just like maintaining your car, having that inspection done is pretty cheap insurance against something larger. Unfortunately, we've had to respond to inspections like that only to find out that whoever installed the roof didn't do it properly, and now there is damage that's occurring. It's a lot easier to fix it when it's small than when of a sudden now it's raining in your dining room.

Are there Obvious Signs of Roof Damage?

Maher: Right. Are there obvious signs of roof damage that a homeowner could kind of look up on their roof maybe not necessarily without getting up on top of the roof, but just looking up? Are there obvious signs of damage that a homeowner could take a look at and say, "Oh, yeah, I need to have a professional come out and check this out"?

Rogenski: Absolutely. There's some stuff that, like you say, if you can get a fairly good look at it. Are you having curling? Are your shingles starting to curl? That's typically a sign of excessive heat, so there's probably an air flow problem probably in your attic, but have someone there and look at, but if you see curling, cupping, not good, have someone get there and look at because it's also not going to fix itself.

Maher: Yes, you want it to be nice and flat.

Rogenski: Yeah, they want to just lay there nice and flat Degranulation, so the pebbles that are on a shingle, some of them by nature just come off number one, over time, and number two, from the manufacturing process. Initially when you put it on, there's some that just come off, they're not well adhered. That's okay, that's normal, that's not something you're worried about.

But if all of a sudden, you're starting to see thin or bare spots on your shingles, spots where you can see that there's less granules or you're looking at the runoff out of your gutter if you have them and all of a sudden you're like, "Why do I have this giant pile of sand coming out of my gutter?" That's definitely something that you should probably have someone come and inspect.

Why is the degranulation occurring? May have been an inexpensive shingle that's not holding up well, maybe a manufacturer's defect, in which case that's where that warranty comes into play and holding whoever the manufacturer is accountable, and they want to be held accountable to that. They don't want to have a bad name out there.

So, I would tell you, cupping, degranulation, and then also where sometimes you can see, maybe it's not your home, but you've driven by a home where the shingles used to be nice and rectangles and the edges were fairly well-defined, and now all of a sudden, they're literally wearing down, so none of these things are no longer rectangles, the edges of our... That's actually the asphalt itself and the matting deteriorating, very bad sign. Yeah, you definitely want to do something about that.

And I guess probably the last thing is, do you have loose shingles? Is there something that's not lining up with the other ones? Meaning has it come loose? Do you have multiple that are loose, because that shouldn't happen at all? So that was either mis-nailed or maybe it was damaged by storm damage or something like that. There can be a variety of reasons, but they should all continue to line up for the life of that roof just fine. You shouldn't have one that's hanging down differently than the others and that sort of thing. So, they should be laying there nice, flat, and straight.

Is Having Moss Growing on Your Roof a Problem?

Maher: What about things like moss starting to grow on your roof, on your shingles? Is that a bad sign that it's retaining moisture or something like that?

Rogenski: Yeah, that's actually a really good point, John. And every situation is a little bit different kind of depending on your surroundings because you're surrounded by trees, are you surrounded by nothing, are you surrounded by pine trees and you're building pine thatch? But yeah, if you are starting to see moss, actual moss building on there, that definitely should be addressed. And there's a lot of different ways to address that.

Unfortunately, we've seen folks who decide that they can fix it themselves and they hop up there with the pressure washer and blow the moss off. The problem with that is they're being a little too aggressive and they're deteriorating their shingles while they're at it. So they got rid of the moss. They also got rid of a lot of the granules and the matting, and there's really starting to take that thing apart. So yeah, moss is a bad sign. That can be treated chemically, and frankly, we usually just gently, we have some tools that we do it with, can gently scrape it out of there.

In homes, I had a home in New Hampshire that accumulated a lot of pine straw. I was surrounded by pine trees. That would build up, and I would have... Number one, it actually caused me a few issues with backing up water by one of my Skylights. Wasn't anything wrong with the Skylight, it was the accumulation of pine straw. But also you can get growth in there.

So, a lot of times, if you're in an area that accumulates a lot of pine straw, might be a great idea to, once a year, have someone get up there and gently and professionally remove that pine straw so that nothing good's going to come from that. But yes, moss is a bad sign and you want to get rid of it because it's going to start to make those actual shingles deteriorate as its little fibrous roots go into them.

Maher: Okay. All right. That's really great information, Brett. Thanks again for speaking with me today.

Rogenski: Thanks, John. I appreciate you having me.
