The insurer actually flies planes over insured properties looking for hazards and unmaintained items. It was such a flight that they pinged me for roof replacement. While it was not an expense I was expecting to have this year, if my roof really does show wear or damage and needs to be replaced I'd rather do it before it actually becomes an issue with leaks or whatever.
That's common although aerials by plane I didn't see as much but obviously tech has improved a lot over the years. If I'm just talking out loud it's possible they saw a lot of granular loss on your roof or aged appearance then they matched up with how old your roof was and suspected it was getting to the end of its
usable lifespan. What a roofer may think will last isn't necessarily the same as what the insurance company is looking at because usable life span and overall lifespan kinda mean two different things. It's not as commonly used as much but on wood shake roofs curling was a common reason for a new roof being needed.
For homes there's actually fairly little that an insurance company can cancel you for once you are past discovery period (that occurs when the policy is considered new business) something I know probably gets lost when talking about the insurance companies canceling policies. It's very regulated industry even in states that are more lax. On auto there are more reasons for non-renewals. On home it was mostly frequency of claims and unacceptable business on premises that I saw. Some policies were non-renewed because the home was written many years ago (and just never caught) incorrectly as in the product it was written in was not appropriate. It had to be pretty egregious for a cancel with legal notice which is done when the policy is not close to its renewal date but whatever the issue is warrants an immediate action.
I dealt a lot with that where we would get photos from the contracted out company the insurance company I worked for used where they would show what needed to be repaired such as wood rot, missing or peeling paint, roof curling or granulation, etc. They would use google maps aerial views for some things like how a property might be kept or additions to the home. It's an expense that an insurance company utilizes every so often to either send physical people out or use aerial footage. Technically insurance agents are also supposed to be doing their own inspections both at new business and over time. Couldn't tell you how many times agents would be surprised at the condition of their insureds property but couldn't deny the photos the 3rd party was taking.
I totally get not wanting that expense especially if it's not something you're having the insurance company pay for minus your deductible.
The bold is what I don't understand. Why call it a 30, 40, 50 year if that isn't the life expectancy of the darn thing. I can't say for sure how old my roof is either. When I had the home inspection, the inspector said the roof appeared newer and that it should last another 20 years. It have been in the house 15 years. So I was expecting another 5 years or so before I had to consider replacement.
I totally understand you on that one. The higher the warranty the stronger the materials are generally speaking. Another example of strength in materials is architectural shingles are stronger than normal 3-tab ones (part of the reasons our HOA requires architectural although aesthetics is also part of it, although looking at it we can only use either Owens Corning or GAF branded shingles anyhow).
The warranty is mostly about an "up to" timeframe. So a 50 year roofing warranty means coverage for the roof up to 50 years usually manufacturing defects, labor and materials, etc but it doesn't mean the roof itself is being warranted to last 50 years. However the higher warranty, the materials used are typically going to be tougher in consideration of things like wind, for hail impact resistance as well as there's also fire resistance ratings too (digging further into it our HOA requires the shingles have at least a B rating for fire which means moderate fire exposure but I don't know that it was a requirement when we moved in, it is now a requirement at least since 2018).
