Any tips for climbing with A rope that is to short?

I have two 30 meter rope and mostly stick to the same single pitch climbs that are bolted for 30 meter ropes. But as I grew in skill I wanted to branch out to other climbing areas, but most other locations in my area are bolted for 40 meter ropes. What should I do? is there a trick I can use or do I just need to bite the bullet and buy a 60 meter rope?

so many options

Are you saying your normal climbs are 15m tall, and the new climbs are 20m tall? If this is the case, you can just climb on your 30m ropes, and then tie them together at the anchor for a double rope rappel. If your belayer wants to TR the climb, you belay them from the top and then both rappel down.

You absolutely should bite the bullet and get the 60m.

It would be safe to lead a 25 meter route with one rope, and trail the second, tie em together at the anchor and rap down.

There are ways to pass a knot on toprope too.

But, and this is the big one. Nobody else will expect you to have such a short rope. Even though you’ll tell them. Mistakes are inevitable and gravity is ever present.

Keep them for the gym or other areas of a confirmed 15m or less height.

Reiterating: buy a 60m rope.

Use with very tall climbers

Every time you try "one weird trick" at the crag you increase your risk of death.

Can you sew ropes together in a way that it is safe?

Don’t do it. Buy the proper gear for whatever you’re doing. 

Learn to TRS. Buy 30m of 6mm for a pull chord

This is a good argument against 50m ropes, but it would be hard to mistake a 30 for a 60.

Ask your parents for a new rope for your birthday.  Doh.

I think that’s the biggest danger.

When he says 30, people aren’t going to think that’s accurate. They’ll assume it’s a 60 that’s been cut, or maybe a 50. 30 is so far off that it’s just not going to register.

Do you remember the ropes that had the last 5 meters or whatever marked? And someone died from rapping off that as the middle? An experienced climber. Seems obvious but it happened.

It’s not so much that the OP couldn’t figure it out. It’s more about best practices and creating fewer problems for yourself.

"Rope manufacturers don't want you to know about this one weird trick."

Just break the route into multiple pitches. Duh.

Many of the crags in NM only need a 40m, which is generally what me and my partners bring. It'd be easy to mistake a 30m for a 40m. 

Not sure where you live, but you might consider getting a 70m instead of a 60. If you get a 60, you may find yourself repeating this dilemma in several months or years when you want to climb something that requires a 70. 60s generally work fine for most climbs in most areas, but it didn’t take long for me to find climbs that made me glad to have a 70.

I have 30, 40, 50, 55, 60, and 70 meter ropes, all of which have valid purposes (and middle marks). Buy a 50 or better yet a 60 and let your skill set progress. 

You could simulclimb up and simulclimb down with your friend. I wouldn't recommend it at all... but you could.

The correct answer is: buy a 60 or 70m rope.
