Tile roofs have the lowest life-cycle cost of any roofing material. They’re built to last for the life of the structures they protect and to retain their appearance for decades with virtually no maintenance. Exceptional thermal insulating performance can lower energy costs by as much as 20%, and building owners can expect lower insurance premiums too, thanks to pest, wind and fire resistance.

Life Cycle Costs
Tile roofs have the lowest life-cycle cost of any roofing material. They’re built to last for the life of the structures they protect, and cost per year of use is the same or less than several other roofing options.
​
While the cost of a tile roof may appear to be a significant investment, the cost of ownership over the years for other roofing materials becomes less attractive when maintenance costs are factored into the investment. Clay and concrete tile roofs are virtually maintenance-free, while after 20 years of ownership, asphalt shingles appear worn or like a patchwork quilt of new and faded colors when worn shingles are replaced during routine maintenance. Unlike tile roofs, which often outlive the life of a structure, asphalt shingles are near the end of their life cycle, requiring replacement. Cedar shake roofing requires treatment every two to three years to maintain color and a level of fire resistance – treatment that requires professional skill to maintain properly – adding hefty maintenance costs to the life cycle cost of a roof.

Reroofing
​When reroofing costs are considered over the lifetime of a home, the advantages of a clay or concrete tile roof are clear.

Resale Value
Both clay and concrete tile add a distinctive presence to any home, providing the kind of curb appeal that adds value. Aging asphalt and wood shingles show color fade and other signs of wear, while tile weathers extremely well, retaining its original color with only a slight natural mellowing over the decades. Other value-adding features include:
​
  • Tile roofs last far longer and retain their appearance far better than other roofing types
  • Minimum maintenance requirements reduce or eliminate annual upkeep costs
  • Exceptional thermal insulating performance lowers energy costs by as much as 20%
  • Pest, wind and fire resistance lowers insurance costs
  • Most manufacturers offer warranties of 50 years or more
  • Tile is environmentally safe and easily recyclable

Maintenance
Tile roofs have minimal need for maintenance – just a visual inspection once a year. With an average moisture absorption of less than 1 percent, clay and concrete tile roofs are naturally resistant to rot, mold and insects and can handle both heavy rain and dry conditions. They stand up to freeze/thaw cycles without damage.

Minimal maintenance means harsh chemical cleaners can be avoided. If repair is required, each individually installed tile can easily be replaced. Lower maintenance keeps annual costs low and also helps satisfy LEED and ENERGY STAR requirements.
