The Lowdown on Fibered vs. Non-Fibered Roof Coatings

The Lowdown on Fibered vs. Non-Fibered Roof Coatings

If you’re like me, you want to make sure your commercial roof is in tip-top shape and can withstand whatever Mother Nature throws its way.

One crucial decision you’ll face is whether to go with a fibered or non-fibered roof coating. Don’t worry. I’ve got you covered with all the details you need to make an informed choice.

Key Takeaways

  • Fibered coatings are tough and resistant to tears and abrasions, but they sacrifice some flexibility and elasticity.
  • Non-fibered coatings are super stretchy and can cover large areas, but they might not be as durable against physical damage.
  • Consider factors like your roof type, surface area, and climate when deciding which coating is best for your needs.
  • Don’t be afraid to ask the experts (like yours truly) for guidance on choosing the right coating for your commercial roof.

What’s the Deal with Fibered Coatings?

A fibered roof coating is like a superhero cape for your roof – it’s infused with tough little fibers (usually fiberglass) that give it extra strength and resistance against tears and abrasions. These fibers can be teeny-tiny or a bit chunkier, but either way, they act like a protective barrier for your roof.

The downside? All that added muscle means fibered coatings aren’t as flexible or elastic as their non-fibered counterparts. But hey, sometimes you gotta sacrifice a little stretch for some serious durability.

The Scoop on Non-Fibered Coatings

On the other hand, non-fibered roof coatings are like yoga pants for your roof. They’re super stretchy and can roll with the punches (or should I say the weather?).

Without those fibers holding them back, these coatings can flex and bend over a larger surface area without cracking or breaking.

The trade-off here is that non-fibered coatings might not be as tough against tears and abrasions as their fibered cousins. But if flexibility is your top priority, these coatings could be the way to go.

Which One Should You Choose?

Which One Should You Choose

Now, this is where things get a little tricky. There’s no one-size-fits-all answer because every roof is a special snowflake with its own unique needs. Here are a few factors to consider:

  • Type of roof/substrate: Some materials play better with fibered or non-fibered coatings.
  • Surface area: If you’ve got a massive roof, a non-fibered coating might be better at stretching to cover that bad boy.
  • Climate and weather conditions: Harsh environments might call for the added strength of a fibered coating.

As a general rule of thumb, lean towards fibered coatings if you’re looking for rugged strength and tear resistance. But if flexibility and stretchability are your top priorities, a non-fibered option could be the way to go.

Popular Polyglass Coatings: Fibered vs. Non-Fibered

Disclaimer: I’m not sponsored by Polyglass or anything, but they’ve got some solid coating options in both the fibered and non-fibered realms. Here’s a quick rundown:

Non-Fibered Coatings:

  • PG 600: A non-fibered aluminum coating that’s great for elastomeric roofs, asphalt BUR roofs, and metal roofs. It’s designed to play nice with asphalt, so no worries about damage.
  • PolyPlus® 60: Similar to PG 600 but a premium grade with longer-lasting durability.
  • PG 200: A modified asphalt coating that works on various roof types, but it’s especially great for metal roofing, masonry, stucco, and more. It can even act as a damp-proofing compound for below-grade walls.

Fibered Coatings:

  • PG 650: The fibered version of PG 600, with added durability and reflectivity thanks to those tough little fibers.
  • PolyPlus® 65: The premium, fibered counterpart to PolyPlus 60. It’s got extra strength and longer-lasting reflectivity.
  • PG 300: Like the fibered big brother of PG 200. It’s great for various roof surfaces and can be used as an adhesive for mineral granules and organic roll membranes. Just remember that it’s not quite as flexible as PG 200.

FAQs

Can I apply a fibered coating over a non-fibered one (or vice versa)

Yep, you can mix and match as long as the coatings are compatible. Just follow the manufacturer’s instructions and get professional advice if you’re unsure.

How long do these coatings typically last?

It varies based on factors like the specific product, application, and environmental conditions. But generally, you can expect anywhere from 5 to 10+ years of protection with proper maintenance and recoating as needed.

Are there any special application considerations for fibered vs. non-fibered coatings?

Fibered coatings might require a bit more elbow grease during application due to their thicker, less fluid consistency. But as long as you follow the manufacturer’s guidelines, you should be golden.

Can I use these coatings on residential roofs, or are they just for commercial buildings?

While they’re most commonly used on commercial roofs, many of these coatings can also be used for residential applications. Just double-check the product specifications and get professional advice if you’re unsure.

How do I properly maintain and care for my coated roof?

Regular inspections, cleaning, and recoating as needed are key. I’d also recommend working with a reputable roofing contractor who can provide specific maintenance guidelines based on your roof type and coating.

Well, there you have it, folks – everything you need to know about fibered vs. non-fibered roof coatings! Remember, the right choice ultimately depends on your unique roof and its specific needs. But with this guide in your back pocket, you’re well on your way to making an informed decision.
