Roof Education

To Maintain A Strong Working Roof, You Can't Set-And-ForgetWe offer repair, replacement and service for the four main types of roofs: Concrete/Clay Tile, Asphalt Shingle, TPO Flat Roofing, and Wood/Cedar Shake. In the Northern California climate we have seen these roofs to typically last anywhere from 20-50 years (see below for more details). Regular maintenance every 2-3 years is crucial to maximize the lifespan of these roofs. Signs of needing a replacement include leaks, worn materials, and aged appearance or color fading.

CONCRETE / CLAY TILE

Very common in the area. These roofs are a “50-year roof” in best-case conditions. In the Northern California climate, we typically see them last for 40-45 years before a replacement is needed. This lifetime is only reached when routine maintenance is done every 2-3 years. If routine maintenance is not completed, the lifetime will decrease significantly.

Common signs when ready to replace:

  • 40+ years old
  • Current Leaks in multiple areas
  • Tiles will look relatively unaged, but the underlaying materials will be very worn (felt, wooden bats, etc.)

Asphalt Shingle / Composition

Very common for the area. The standard for these roofs are a “30-year roof” in best-case conditions. In the Northern California climate, we typically see them last for 20-25 years before a replacement is needed. However, there are several upgraded options for a 40 or 50 year lifetime. This lifetime is only reached when routine maintenance is done every 2-3 years. If routine maintenance is not completed, the lifetime will decrease significantly.

Common signs when ready to replace:

  • 20+ years old
  • Current Leaks in multiple areas
  • Shingles will change color with age. They appear to look darker and scuffed; and even have silver edging.

TPO Flat Roofing Membrane

When it comes to flat roofing, there are a few options: rolled asphalt, tar, gravel, etc. If your roof pitch is below 2/12, Loveland Roofing strongly recommends using TPO. Also known as “thermoplastic polyolefin” membrane. This is a single ply roofing system often used for flat roofs both residential and commercial.

TPO is a blend of ethylene propylene rubber and polypropylene that’s reinforced with polyester and heat-weldable at the seams. It’s often white and highly reflective, which can help save energy.

TPO roofs have many benefits, including:

  • Durability: TPO is resistant to heat, UV, and fungus, and can last 20–30 years if properly maintained.
  • Flexibility: TPO is flexible in colder temperatures and doesn’t require plasticizers.
  • Cost-effectiveness: TPO is affordable and considered one of the most budget-friendly ways to improve a building’s energy efficiency.

Wood / Cedar Shake

Much less common in the area. These roofs are not the most modern form of roofing, and are therefore phasing out. These roofs are a “30-year roof” in best-case conditions. In the Northern California climate, we typically see them last for 20-25 years before a replacement is needed. This lifetime is only reached when routine maintenance is done every 2-3 years. If routine maintenance is not completed, the lifetime will decrease significantly.

Common signs when ready to replace:

  • 20+ years old
  • Current Leaks in multiple areas
  • Wood shake shingles will look much darker and very aged. At this point, they crack and fall apart.
