If you own your house or supposing you owned a house, do you/would you inspect your roof occasionally or just wait till it leaks before....

I had it replaced about 8 years ago as some tiles had blown away in a wind storm. I didn't wait for leaks.

I not only would wait for leaks, I would wait until I ran out of buckets.

I'm good, I had my roof replaced about 5 years ago. 

I don't go up on the roof. My contractor has a roofing guy who does that.

Every year just before the cool weather sets in (but not while it's so hot up there I fry), I climb up on my roof and thoroughly inspect it.  I clean and seal any places around vents, the chimney, nail holes, or valleys that show signs of wear or fatigue.  I also clear out the gutters, wash out the rain gauge, inspect the solar panel, battery, and connections to the weather station, check the guy wires to the anemometer (seal if needed), and adjust the directional on the old mermaid wind vane.   

My husband handles that stuff.

Thanks for the prompt; it's probably time to get my roofer to check it out, not that there's any leakage or damage immediately evident.
