Roofing Materials and Costs
The type of roofing material you choose to install will significantly impact your total costs. Let’s look at the average prices for some of the most common roofing materials:

Asphalt shingles are the most common roofing material. They are known for easy installation, low costs, and decent durability, typically lasting 15 to 30 years with minimal maintenance.
Metal roofing: $8-$16 per square foot
Metal roofs are more expensive upfront but offer excellent durability, weather resistance, and energy efficiency, often lasting 40 to 70 years with proper installation and minimal upkeep.
Wood shingles: $4-$9 per square foot
Wood shingles are known for their clean, natural aesthetic and moderate durability over time. They require regular maintenance and are best suited for dry climates to avoid mold or rot.
Wood shakes: $6-$14 per square foot
Wood shakes offer a rustic appearance given they are very textured and thick. They’re also more durable than wood shingles but require higher maintenance and care.
Concrete tile: $10-$20 per square foot
Concrete tiles are incredibly long-lasting and durable, often holding form for over 50 years. They’re resistant to fire and keep away pests but are heavy and require reinforced roof framing.
Clay tile: $10-$18 per square foot
Clay tiles resist salt, fire, and rot. This roofing material is extremely durable, lasting anywhere from 50 to 100 years with proper maintenance. Clay tiles are ideal for roofs in hot, dry, or coastal climates, perfect for California!
Slate shingles: $10-$30 per square foot
Slate is a premium roofing option known for its elegant look and exceptional longevity, often lasting 75 to 100 years. It is heavy however and requires expert installation.

Repair vs Replace Roof Shingles
If only a few shingles are cracked, curling, or missing, it’s often cheaper to replace those shingles than tear off the entire roof. It’s not always necessary to replace your roof, especially if it’s relatively new (under 10 years old) and otherwise in good shape. Simply repairing those shingles that have been compromised is a lot less work and will save you money from a full roof replacement.
Can A Roof Be Repaired Instead Of Replaced?
Yes, in many cases a roof can be repaired instead of fully replaced. Choosing roof repair over replacement makes sense when the damage is limited to a small area, the roof is less than 10 years old, leaks are not ongoing, and the overall structure is still sound.
However, if the roof has widespread issues, repeated leaks, or is nearing the end of its lifespan, replacement is usually the better and longer-lasting option.
