I’ve fallen a couple times, but no serious damage is visible on the helmet except for a couple divots here and there.
Should I consistently be replacing my helmet after a certain amount of time? After every relatively serious fall?
Welcome to Bicycles Stack Exchange
Bicycles is a question and answer site for people who ride, repair, or build bicycles. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about bicycles and bicycling.
We're a little bit different from other sites. Here's how:
Ask questions, get answers, no distractions
This site is all about getting answers. It's not a discussion forum. There's no chit-chat.
Just questions...
...and answers.
up vote
Good answers are voted up and rise to the top.
The best answers show up first so that they are always easy to find.
accept
The person who asked can mark one answer as "accepted".
Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.
When or how often should I replace my bike helmet?

Helmets should be replaced roughly every 5 years and after any crash where your head makes contact with the ground.
Helmets will crumble, compress or otherwise deform in sometimes hard to see ways when you hit the deck. The structural integrity of the thing will be massively diminished after even a relatively tame fall. This is one area where you don't want to mess around much.

The general rule is every 3-4 years or after a crash. Some people say that excessive sweat or UV exposure can also degrade your helmet, but no one has proven that so far.

Get answers to practical, detailed questions
Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.
Ask about...
- Specific issues with bicycles
- Specific issues with bicycling
- Real problems or questions that you’ve encountered
Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.
Questions that need improvement may be closed until someone fixes them.
Don't ask about...
- Anything not directly related to bicycles or bicycling
- Questions that are primarily opinion-based
- Questions with too many possible answers or that would require an extremely long answer
Tags make it easy to find interesting questions
All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.
Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

@neilfein - check your helmet's warranty and manual to see exactly what kind of solid objects it recommends crashing into. ;-) - matt smillie Sep 2 '10 at 23:22
