Tax Depreciation House Hack Question

[Frank Szymanski]

Hello all!

General tax question:

1. Can I write off the expenses of a new roof and a driveway repair during a room "house-hack" where it is a primary residence? 

2. Can you write off expenses like a new like a new roof/driveway repair job that was done during your primary residency while you were transitioning it to a rental property ? Would these be classified separately as "start-up" expenses? 

Thank you in advance!
