Flooring – How to strengthen attic rafters for storage

atticflooringloft

I have standard 2×4 rafters and want to use it just for storage and I am worried they are not strong enough. I was thinking I could buddy ( or sister) up the 2×4's with another 2×4 or 2×6. or stack another 2×4 onto the existing rafter. I am no engineer but logically I am thinking this would work. I am open to any idea that is safe and easy to do.

Depending on the specific structure of your ceiling, this could be a very bad idea.

If done badly, it will simply increase the weight on the structure, not add strength at all.

As a general rule, you should be able to put reasonable storage in the roof space without added effort. (boxes of books ok. crates of lead not ok)

If you have concerns though (and you do, because you're asking), you need to speak to a qualified engineer as each roof is different. (Age, Design, Materials, Climate, Prior Use, Condition, supporting structure are just a few important factors)
