Understanding Roof Warranties:

What San Diego Property Owners Need to Know 

At TWM Roofing, we believe that a well-informed homeowner or property manager is a confident one. When it comes to roofing, warranties can be confusing, especially when you hear terms like "lifetime shingles" or "limited lifetime warranty."

What Does "Shingle Lifetime" Really Mean?

The term "lifetime shingles" is commonly used in the roofing industry, but it doesn't mean your roof will last forever. Manufacturers typically define "lifetime" as the period during which the original homeowner owns the home. In reality, most asphalt shingles last 20 to 30 years under normal conditions.

Several factors can influence shingle longevity:

• San Diego's sunny climate (UV exposure)
• Roof slope and ventilation
• Quality of installation
• Material grade (3-tab vs. architectural shingles)

The Truth About Limited Lifetime Warranties

Most shingle warranties are limited lifetime, meaning:

• The warranty lasts as long as you own your home (for single-family homes only).
• It covers manufacturer defects in the shingles, not damage from storms, poor ventilation, or improper installation.
• The warranty often offers full coverage for the first 10 years, then becomes prorated, reducing the value each year afterward.
• Many warranties require you to register your roof to receive full benefits.

Transferable? Sometimes. If you sell your home, the warranty may transfer once to the next owner, but usually only for a limited period (e.g., 10 years).

Don’t Overlook Workmanship Warranties

In addition to manufacturer warranties, you should consider the workmanship warranty offered by the roofing contractor.

Workmanship warranties cover installation-related issues, like:

• Flashing mistakes
• Poor sealing
• Improper shingle alignment

TWM Roofing offers an industry-leading workmanship warranty that gives you peace of mind knowing your roof was installed right the first time.

Home Warranty with Roof Coverage

A home warranty with roof coverage is a separate type of protection often included in service contracts provided by third-party warranty companies. Unlike manufacturer or contractor warranties, these plans are typically designed to cover basic roof leak repairs caused by normal wear and tear and not full roof replacements or issues due to poor installation. Coverage is usually capped by a dollar amount per year and may not include all roofing materials or systems. While this can be a helpful option for budget-conscious homeowners, it’s important to read the fine print and understand the limitations. At TWM Roofing, we recommend pairing any home warranty with a properly installed roofing system and a contractor warranty, ensuring your roof is fully covered from both a repair and structural standpoint.

5-Year Workmanship Warranty Roofing

A 5-year workmanship warranty for roofing provides homeowners with valuable protection against installation errors or defects that could lead to leaks, structural issues, or premature roof failure. This type of warranty is offered by the roofing contractor, not the manufacturer and guarantees that the roof was installed according to professional standards. At TWM Roofing, our 5-year workmanship warranty reflects our confidence in the skill and care we bring to every project. If any problems arise due to installation within the warranty period, we’ll make it right at no additional cost. This level of coverage offers homeowners peace of mind, knowing that their investment is backed not just by materials, but by quality craftsmanship.

Mule-Hide Warranty

The Mule-Hide Warranty is a trusted protection plan for low-slope and flat roofing systems, commonly used in commercial buildings and residential structures with flat or low-pitched roofs. Mule-Hide offers several levels of warranty coverage, including membrane-only warranties and system warranties that cover materials and labor when installed by an authorized contractor like TWM Roofing. Warranty durations range from 10 to 30 years, depending on the product and system used.

As an experienced roofing contractor familiar with Mule-Hide systems, TWM Roofing ensures each project meets the manufacturer’s specifications, helping property owners qualify for full warranty benefits. This warranty is especially valuable for protecting against membrane defects, seam failures, and water infiltration, providing long-term durability in even the toughest environments.
