Signs Your Roof Needs Help
Knowing when to replace your roof is crucial to avoiding bigger problems. Roofs over 20 years old, or those with significant wear, should be evaluated by a professional to make sure your home stays well-protected.

01 — the basics
Understanding Your Roofing System
Your roof does more than cover your home — it protects, insulates, and supports your house's overall structure, with several layers and materials working together against rain, wind, and temperature swings.
Asphalt shingles
Affordable and widely used — a solid fit for most climates.
Metal roofing
Long-lasting and energy-efficient, ideal for extreme weather.
Clay tiles
Perfect for warm regions — durable and great at reflecting heat.
Wood shakes
A rustic look, though they ask for more upkeep over time.
Homes in harsher conditions often do best with durable materials like metal or tile, while milder climates leave more room to choose asphalt or wood on looks alone.
02 — How It's Built
How Your Roofing System Works
A roofing system isn't just what you see on the surface — it's a combination of layers, each with its own job to do.
01
Roof deck
The foundation of your roof, supporting every other layer.
02
Underlayment
A protective barrier that keeps moisture from reaching the deck.
03
Roofing material
The outer layer — shingles, metal, or tile — protecting your home and adding insulation.
04
Ventilation & insulation
Keeps airflow and temperature in check, preventing mold and moisture buildup.
Together, these layers keep your home safe, comfortable, and energy-efficient.

Consider Roofing Material Options
Asphalt shingles are the most common thanks to their affordability and durability. Metal roofing offers long-lasting protection and energy efficiency, while clay or concrete tile brings a classic, weather-resistant option. For something more sustainable, slate or wood shakes add natural beauty and longevity. The best material for your roof comes down to your budget, climate, and desired look.
