Thompson Water Seal applications on roof shingles involves considerations of waterproofing. Asphalt shingles specifically, may react differently. The primary function of Thompson Water Seal is waterproofing, however roof shingles already provide a level of protection against water, and thus, the application might not be necessary or even advisable. Asphalt shingles may degrade when Thompson water seal is applied to it.

Asphalt Shingles 101: Understanding Their Waterproofing Needs
Let’s dive into the world of asphalt shingles, shall we? Think of them as the reliable workhorses of the roofing world, commonly found protecting homes far and wide. These shingles are not just pretty faces; they’re carefully crafted layers designed to keep the elements at bay.
At their core, asphalt shingles are made up of a fiberglass mat, which acts as the backbone, saturated with asphalt for water resistance, and then topped off with mineral granules. Those granules? They’re not just there for looks; they shield the asphalt from the sun’s harsh UV rays, which can otherwise cause it to break down. So, right off the bat, they’re designed to inherently resist water, like a well-prepared umbrella!
However, and this is a big however, life isn’t always sunshine and rainbows, is it? Just like our favorite jeans fade over time, asphalt shingles can also degrade. Think of it as a slow and steady battle against the elements. The sun beats down on them, rain washes over them, and snow piles up, all taking their toll.
And let’s not forget the wild card: climate. If you live in a place with scorching summers and freezing winters, your shingles are going to face a tougher challenge than those chilling in a mild climate. The constant expansion and contraction can lead to cracks and loss of those crucial granules. This is why maintaining their water-resistant properties is so important. In harsh climates, think of it as giving your shingles a fighting chance, because without that extra bit of protection, you might be facing leaks and a whole lot of trouble down the road!
Thompson Water Seal: Decoding the Label – It’s More Than Just Water, Right?
So, you’ve probably seen Thompson Water Seal at your local hardware store, maybe even grabbed a can or two. But what exactly is this stuff? Think of it as a raincoat… for your wood. Thompson Water Seal is a popular water repellent and sealant designed to protect surfaces from the damaging effects of moisture. It’s formulated to penetrate the surface, creating a barrier that helps prevent water from soaking in.
But let’s get real, the label mostly shows decks, fences, and other wooden structures gleefully shedding water. The marketing materials highlight its ability to prevent water damage, resist mildew, and protect against fading and discoloration caused by the sun’s UV rays. They paint a picture of perfectly preserved wood, standing strong against the relentless assault of Mother Nature.
Now, here’s the kicker. While Thompson Water Seal boasts impressive waterproofing capabilities, it’s primarily intended for wood. Specifically, things like wood shingles, shakes, decks, fences, and siding are its jam. The product is formulated to work with the unique characteristics of wood, allowing it to breathe while repelling water. This “breathability” is key – it prevents moisture from getting trapped inside the wood, which can lead to rot and decay. The manufacturer’s claims center on keeping your wooden surfaces looking good as new, longer. But what about asphalt shingles? Well, that’s what we’re here to find out.
The Compatibility Conundrum: Why Asphalt Shingles and Thompson Water Seal May Not Mix
Okay, so you’re thinking of giving your asphalt shingles a little extra “oomph” with Thompson Water Seal, huh? Hold your horses! Before you go slathering it on, let’s talk about why this might not be the match made in roofing heaven you’re hoping for. Think of it like trying to fit a square peg in a round hole—or maybe more accurately, trying to get oil and water to play nice.
At the heart of the matter is the potential for some serious chemical chaos. Thompson Water Seal is designed with specific materials in mind (primarily wood, as we’ve mentioned), and its ingredients may not play well with the asphalt in your shingles. It’s like introducing two rival gangs—you might end up with a turf war on your roof!
Specifically, you need to consider what this sealant could do to your shingles long term.
Shingle Flexibility: Bending But Not Breaking… Until Now?
Asphalt shingles are designed to be flexible, allowing them to expand and contract with temperature changes. This flexibility is crucial for preventing cracks and leaks. However, Thompson Water Seal could potentially cause the shingles to become brittle and stiff, making them more susceptible to damage from the elements. Imagine trying to do yoga after being encased in cement – not pretty!
Granule Adhesion: Losing Your Grip (Literally!)
Those tiny granules on your asphalt shingles are there for a reason: they protect the asphalt layer from the sun’s harmful UV rays and give your roof its color. When you apply a sealant like Thompson Water Seal it might interfere with the granules ability to stick to the shingle, causing them to loosen and wash away over time. This leaves your roof exposed and vulnerable, like a knight losing his armor piece by piece.
Overall Lifespan: Shortening Your Roof’s Retirement Plan
Ultimately, using Thompson Water Seal on asphalt shingles could significantly reduce the overall lifespan of your roof. Instead of lasting for 20-30 years, you might find yourself needing to replace your roof much sooner than expected. Think of it as prematurely aging your roof, turning it into a grumpy old-timer before its time. Replacing a roof is expensive, so you want to do whatever you can to avoid that!
Application Caveats and Best Practices (If You Proceed)
Okay, so you’ve read all the warnings, consulted the experts, and still think Thompson Water Seal is the answer for your asphalt shingles? Alright, alright, I can’t stop you. But, since you’re determined, let’s at least make sure you do it the safest way possible. Think of this section as your “damage control” guide. Remember, I’m not recommending this, but if you’re going to do it, let’s do it responsibly.
Prep is Key!
First things first: Surface Preparation is absolutely crucial. You wouldn’t paint a dirty car, would you? Same principle here. We’re talking about a thorough cleaning. Get rid of all that moss, algae, dirt, and loose granules. A gentle scrub with a soft brush and some mild detergent is your best bet. Avoid harsh chemicals or power washing, as these can damage the shingles even further. Now, this is important: let those shingles dry completely! Water Seal over moisture is a recipe for disaster. Give it a good 24-48 hours of dry weather before you even think about opening that can.
Application 101: A Light Touch Is Best
If you can, test a small area of the shingle for compatibility issues. If everything goes well, apply with an airless sprayer or roller, thin coats are better than thick coats. Avoid heavy saturation and allow each coat to dry completely before considering another. Remember, you’re aiming for a light barrier, not an encapsulation. Overdoing it can lead to cracking and peeling, which is exactly what we’re trying to avoid!
Safety First, Always!
Let’s talk safety, shall we? Thompson Water Seal, like most sealants, has some fumes you don’t want to be breathing in all day. So, ventilation is your best friend! Open windows, use fans, or even better, wear a respirator. Protect your skin with gloves and eye protection. And for the love of all that is holy, keep children and pets away from the area until the sealant is completely dry.
Decoding the Fine Print: Manufacturer Guidelines and Warranty
Let’s get down to brass tacks, shall we? We’ve talked a lot about the what-ifs and maybes of Thompson Water Seal on your asphalt shingles. But what does the actual source say? It’s time to pull out the magnifying glass and decode the fine print – the manufacturer’s instructions and warranty information. Think of it as reading the ancient scrolls for roofing wisdom (minus the dusty library and questionable librarians).
First, you’ll need to grab your Thompson Water Seal can or head to their website, because this information is gold. We’re looking for the “Application” section and the “Warranty” details. You’ll want to scrutinize it for any mention of asphalt shingles. Does it specifically say, “Great for asphalt shingles!”? Or does it list every surface except the one you’re interested in? More often than not, the absence of a mention speaks volumes.
Does the Warranty Cover Asphalt Shingles? Don’t Bet the Roof on It!
This is the million-dollar question: Does the Thompson Water Seal warranty cover applications on asphalt shingles? Sadly, the answer is almost always a resounding “no.”
Think of it this way: warranties are essentially promises. The manufacturer is promising that their product will perform as expected on approved surfaces. If you use it on something they haven’t approved, that promise is null and void. It’s like buying a phone case guaranteed to protect your phone, then using it as a coaster and complaining when your coffee spills.
Disclaimers and Warnings: The Red Flags You Can’t Ignore
Pay close attention to any disclaimers or warnings related to using the product on non-recommended surfaces. These are often buried in the smallest font imaginable, but they’re crucial.
These disclaimers might say things like: “Use on non-recommended surfaces may result in product failure,” or “Manufacturer is not responsible for damage resulting from improper application.” Basically, they’re saying, “We told you so!” if things go south.
Bottom Line: Always, always, ALWAYS read the manufacturer’s instructions and warranty information before applying any product to your roof. It could save you a lot of heartache (and money) down the road. Because in the end, reading the instructions, is a lot easier than replacing your roof.

The Good, the Bad, and the Leaky
So, what did we find? Well, it’s a mixed bag, to say the least.
-
The Occasional “Win”: Some homeowners report initial satisfaction, noting a temporary improvement in water repellency and a perceived darkening of the shingles that made them look “newer.” These folks often live in areas with mild climates and may have applied the sealant to relatively new roofs. But here’s the kicker: these positive reviews are often followed by updates months later that aren’t so rosy…
-
The “Oops, It’s Worse Now” Club: This is where things get interesting (and a little sad). Many users report that after a year or two, problems start popping up. We’re talking about issues like:
- Granule Loss Gone Wild: Asphalt shingles have those little granules for a reason—UV protection! Some homeowners noticed significant granule loss after applying Thompson Water Seal, essentially leaving their roofs more vulnerable to sun damage.
- Cracking and Curling: Others reported that their shingles became brittle and started to crack or curl. Not a good look and definitely not good for water protection.
- A Sticky Situation: Then there’s the issue of the sealant becoming tacky over time, attracting dirt and debris. Imagine a roof covered in a layer of sticky grime – not exactly the picture of curb appeal.
-
The “Never Again” Brigade: These are the folks who learned the hard way. They might have started with good intentions, but the end result was a roof in worse shape than before. Their advice? “Don’t do it!”
The Bottom Line: Proceed with Caution (Seriously!)
Based on our research, the overwhelming consensus from homeowners is that using Thompson Water Seal on asphalt shingles is a risky move. While some might experience temporary benefits, the potential long-term consequences – granule loss, cracking, and decreased lifespan – simply aren’t worth it.
Of course, individual experiences can vary depending on factors like climate, shingle type, and application technique. But the general trend suggests that this is one DIY project best left undone.
So, can you use Thompson Water Seal on your shingles? Technically, yeah, you can, but should you? Probably not. There are much better options out there specifically designed for roofs that will likely give you better, longer-lasting results and save you headaches (and potentially money!) down the road. Happy sealing!
