Layering It Up: Underlayment and Flashing
Now, we’re getting into the nitty-gritty. We lay a high-quality underlayment on the deck to keep your roof waterproof. Think of it as an extra shield against moisture. Then, we install flashing in vulnerable spots like valleys, chimneys, and vents. Flashing keeps water from sneaking in where it shouldn’t.
But why do we need these extra layers? Let’s peel back the layers and understand their importance.
Underlayment: The Moisture Barrier
Imagine you’re making a sandwich. The bread might be delicious, but it needs something to keep the moisture from your juicy fillings from making it all soggy, right? That’s where the underlayment comes in.
The underlayment is like the plastic wrap around your sandwich. It prevents moisture from seeping into your home.
If, for some reason, water gets past your shingles, the underlayment is a second line of defence. It adds an extra layer of protection against leaks.
Just as a well-wrapped sandwich stays fresh, a roof with proper underlayment can have a longer life.
Flashing: The Leak Stopper
Have you ever tried to patch up a leak in an old bucket with duct tape? It might work for a while, but it is not a long-term solution. That’s where flashing comes in.
Sealing Vulnerable Spots:
Flashing is like the silicone sealant that stops leaks. It’s used around areas prone to water intrusion, like roof valleys, chimneys, and vents.
Preventing Water Damage:
Without flashing, water could find its way into your home through these vulnerable spots. Flashing redirects water away from these areas, keeping your home dry.
Extending Roof Life:
By preventing leaks, flashing contributes to the longevity of your roof. It’s like the guardian that stands between your home and water damage.
So, while these might not be the show’s stars, underlayment and flashing are the unsung heroes that keep your roof strong and waterproof.
