How long did the new roof last compared to what was promised?
Roofs usually outlast the warranty, not the promise.
Most asphalt shingle roofs last 20 to 30 years, and the warranty often covers 25 to 30. The promise is usually the warranty, so if yours failed early, that's the exception, not

Why?
Warranty is the promise Roofers usually promise the warranty length, not a specific lifespan, so compare against that.

What type of roof is it: Tile or slate. 50 years or more, but installation matters. If it failed in 20, that's a workmanship issue, not wear.

What's the biggest roof lifespan versus warranty mistake?
The biggest mistake is assuming the roof's lifespan is the promise. The warranty is the promise, and it usually covers defects, not normal aging. If your roof failed early, check the warranty terms and your installation contract first, not the calendar. Get a professional inspection to document the cause before filing a claim.
How do you decide if your roof's lifespan is fair?
- Find your original roof contract and warranty paperwork.
- Note the warranty length and what it covers, like defects or workmanship.
- Compare the failure date to the warranty end date, not the typical lifespan.
- If it failed early, get a written inspection report and photos before contacting the roofer.

What does the warranty actually cover?
It covers defects, not wear and tear. Roof warranties typically cover manufacturing defects and workmanship for a set period, but not storm damage, poor maintenance, or normal aging. Check the fine print for what's
How do I prove it wasn't storm damage?
Get the weather report for the day it failed. Storm damage claims hinge on whether a storm actually hit your roof that day. Pull the official weather data for your address and the date, then compare it to the damage pattern.
Should I get a second opinion from another roofer?
Yes, get a second opinion. If the first roofer's estimate feels high or the sales pitch was pushy, another set of eyes is cheap insurance on a five-figure job.
