Top 5 Signs You Need a New Roof in Spanaway

A healthy roof does more than keep you dry — it protects your entire home from water intrusion, mold, insulation issues, and structural damage. In a place like Spanaway, where wind, rain, and seasonal storms are common, your roof takes a beating year-round.

If you’re wondering whether it’s time to replace yours, here are the top five signs Spanaway homeowners should never ignore.

Missing, Curling, or Damaged Shingles

Shingles are your roof’s first layer of protection. If you notice patches where they’re missing, curled up at the edges, cracked, or losing granules, that’s your roof waving a red flag.

Over time, shingles can weaken due to weather, improper installation, or age. In the Pacific Northwest, heavy rains and moss growth only speed up the wear.

Why it matters: Exposed underlayment or decking leads to leaks — and eventually rot. Early action saves money.

Pro Tip: After every big storm or windy day, take a quick look at your roof or your lawn for stray shingles.

Leaks or Water Stains Inside Your Home

Brown spots on your ceiling, paint bubbling, or that faint mildew smell in the attic? These are signs that water is finding its way inside — even if you don’t see a direct drip.

Often, leaks begin small and stay hidden. But over time, they weaken drywall, flooring, and even your home’s frame.

Spanaway homes with older roofs are especially vulnerable. Even a tiny breach can let in enough moisture to cause mold or insulation damage behind the scenes.

Don’t wait until it’s pouring inside — a leak is often the last symptom of an old or failing roof.

Sagging or Drooping Roof Line

If your roof is starting to look uneven, wavy, or sagging in certain areas, that’s a serious warning sign. It typically means moisture has compromised the structure underneath — often the plywood decking or framing beams.

This can happen due to:

Prolonged roof leaks
Rotting wood under old shingles
Poor ventilation in attic spaces

Sagging is a structural issue, not just cosmetic. It usually requires a full replacement and should be evaluated immediately.

Your Roof Is Over 20 Years Old

Even a roof that looks fine on the outside may be nearing the end of its life.

Most asphalt shingle roofs last between 20–25 years depending on the material and installation. If your home was built in the early 2000s (or earlier), your roof might already be past its prime.

Can’t remember the last time your roof was replaced? A professional inspection can help you determine age and condition — at no cost.

Moss, Algae, and Black Streaks

In Spanaway’s moist climate, moss and algae thrive. While they might seem harmless, they hold moisture on the surface of your shingles — which breaks them down faster.

Moss also creeps into the spaces between shingles, lifting them and making room for leaks.

You might see:
• Green fuzzy moss on shady parts of the roof
• Black streaks caused by algae
• Discoloration or uneven wear

While cleaning moss can help temporarily, a roof showing excessive biological growth is often nearing the end of its life cycle.

Should You Repair or Replace?

If you’re only seeing one or two isolated issues, repairs might get the job done. But if your roof has multiple signs — or is older than 20 years — a roof replacement in Spanaway could be the smarter investment.

A new roof:
• Increases resale value
• Improves energy efficiency
• Boosts curb appeal
• Comes with manufacturer warranties
