Roofing problems are something most homeowners in Tacoma, Washington will deal with eventually — thanks to our wet winters, moss-loving climate, and ever-changing Pacific Northwest weather. But the good news? Many of the most common roofing issues are preventable if you know what to look out for.
Let’s break down what goes wrong (and how to make it right before it becomes a major headache).
1. Leaks and Water Damage
The Issue:
With all the rainfall we get in Tacoma, roof leaks are at the top of the list. They often stem from broken shingles, flashing failures, or clogged gutters.
How to Avoid It:
✅ Schedule annual inspections
✅ Clean your gutters regularly
✅ Watch for water stains inside your attic or ceiling
2. Missing or Damaged Shingles
The Issue:
Shingles can blow off during windstorms or curl and crack with age. Once damaged, they leave your roof vulnerable to leaks and UV damage.
How to Avoid It:
✅ Use high-quality shingles (like GAF or Malarkey)
✅ Have repairs done immediately after a storm
✅ Don’t ignore loose or flapping shingles
3. Poor Ventilation ️
The Issue:
Improper attic ventilation can lead to mold, rotting wood, and even higher energy bills. In winter, it contributes to ice dams; in summer, to heat damage.
How to Avoid It:
✅ Ensure balanced airflow: 50% intake + 50% exhaust
✅ Have a roofer check ridge vents, soffits, and attic air movement
4. Moss and Algae Growth
The Issue:
Especially on the shaded north-facing sides of roofs in Tacoma, moss traps moisture and slowly breaks down shingles.
How to Avoid It:
✅ Trim overhanging branches
✅ Use zinc or copper strips near the ridge
✅ Schedule professional cleaning (skip the pressure washer!)
5. Flashing Failures
The Issue:
Flashing seals the most vulnerable areas: chimneys, skylights, and vents. If improperly installed or deteriorated, it’s a major source of leaks.
How to Avoid It:
✅ Make sure flashing is part of your routine inspections
✅ Always hire professionals to install or repair flashing properly
6. Ponding Water on Flat Roofs ️
The Issue:
If your home or garage has a flat roof, standing water can indicate poor drainage and lead to leaks or sagging.
How to Avoid It:
✅ Have a proper slope designed into your flat roof
✅ Install internal drains or scuppers
✅ Use a quality membrane like Duro-Last or Duro-Tuff®
7. Improper Installation
The Issue:
Even the best materials can fail if the roof isn’t installed correctly — and it’s one of the leading causes of premature roofing issues.
How to Avoid It:
✅ Work with licensed, insured, and certified contractors
✅ Look for manufacturer certifications (like GAF Master Elite or Malarkey Emerald Pro)
✅ Read reviews and ask to see recent local jobs
Final Thoughts
Most common roofing issues don’t start with a major failure — they begin small. Whether it’s a little moss, a cracked shingle, or a poorly vented attic, ignoring those warning signs can turn a $200 repair into a $15,000 replacement.
That’s why regular inspections, quality materials, and trusted local professionals are key.
