Why Your Roof Needs Great Flashing: A Friendly Guide to Keeping Your Home Dry

 Hey there! If you’re a homeowner, you’ve probably thought about your roof at some point—especially when it’s pouring rain or after a big storm. You might picture those asphalt shingles up there, doing their job to keep your home dry. But here’s something you might not think about often: the unsung hero of your roof, called flashing. Trust me, it’s a big deal, and I’m gonna break it down for you like we’re just hanging out. By the end, you’ll see why working with a solid roofing company like Republic Exteriors is the way to go for keeping your roof in tip-top shape.

So, What’s This Flashing Thing?

Picture flashing as the raincoat for your roof. It’s usually made of metal—like aluminum, steel, or copper—and it’s placed in spots where your shingles alone can’t keep water out. Think of it as a guide that steers rainwater away from tricky areas and sends it safely to your gutters. Without flashing, water could sneak into your home, and nobody wants that!

These tricky spots include places like:

  • Where two parts of your roof slope together (called valleys)

  • Around your chimney

  • Near skylights or vents

  • Where your roof meets a wall (like at a dormer)

  • Along the edges of your roof

Basically, anywhere your roof changes direction or has something poking through it, flashing steps in to save the day.

Why Flashing Matters for Your Asphalt Roof

You might be thinking, “My shingles look fine, so why do I need flashing?” Great question! Asphalt shingles are awesome for covering big, flat areas of your roof. They overlap and use gravity to shed water like champs. But in those weird corners, edges, or spots where things like chimneys pop up, shingles need a little help. That’s where flashing comes in.

If you skip flashing or it’s not done right, here’s what could happen:

  • Water sneaks under your shingles and soaks the wood underneath.

  • Leaks start, and you might not notice until your ceiling’s stained.

  • Mold or rot sets in, which is a headache to fix.

  • Your roof wears out way faster than it should.

Even the fanciest shingles won’t last without good flashing. It’s like trying to bake a cake without a pan—things just fall apart.

The Different Kinds of Flashing

Not all flashing is the same. Each type has a specific job, like players on a team. Here’s a quick rundown:

  • Step Flashing: This goes where your roof bumps into a wall, like around a chimney or dormer. It’s layered with the shingles like steps on a staircase to keep water out.

  • Valley Flashing: This sits in the V-shape where two roof slopes meet. It handles a ton of water during storms.

  • Drip Edge Flashing: You’ll find this along the edges of your roof. It makes sure water flows into your gutters instead of sneaking under the shingles.

  • Counter Flashing: This works with step flashing, tucking into walls or chimneys for extra protection.

  • Vent Pipe Flashing: This wraps around pipes or vents sticking out of your roof, sealing them tight.

Each piece is like a puzzle part, making sure your roof stays watertight.

What Happens When Flashing Goes Wrong?

Bad flashing is one of the top reasons roofs leak. I’ve seen it happen, and it’s not pretty. Here’s what can go wrong:

  • Rusty or Missing Flashing: Over time, metal can rust or get blown off if it’s not secured well.

  • Sloppy Installation: If the flashing isn’t layered right with the shingles, water can slip through.

  • Old Sealant: Flashing often uses caulk or sealant that wears out. If it’s not replaced, leaks can start.

  • Reusing Old Flashing: Some roofing companies cut corners by leaving old flashing when they put on new shingles. That’s a big no-no and can even void your warranty.

Even a tiny mistake can let water in, and over time, that adds up to big problems. That’s why you want a roofing company that knows their stuff, like Republic Exteriors.

Flashing and the Rules

Here’s something else to know: most places have building codes that say flashing is a must in certain spots, like along the edges or where walls meet the roof. If your roofing company skips this, you could end up with a roofing protection  that doesn’t pass inspection—or worse, one that leaks. A good roofing company follows these rules and makes sure everything’s done right. At Republic Exteriors, they stick to local codes and manufacturer guidelines, so you’re covered.

How to Keep Your Flashing in Great Shape

Your flashing isn’t high-maintenance, but it needs a little love now and then. Here’s what you can do:

  • Check it out once a year, especially after big storms. Look for rust, warping, or anything that looks loose.

  • If you see old caulk cracking, get it replaced.

  • When it’s time for a new roof, make sure the roofing company swaps out the old flashing for new stuff.

  • For tricky spots like valleys or chimneys, call in a pro to take a look.

Taking care of your flashing means your roof will last longer, saving you money in the long run.
