I've heard a lot of horror stories about players acting suspiciously when they arrive to Vallaki, only to become aggressive when they're met with suspicion. If you think there's a chance your players might pick a fight with the guard, I hope this map will serve you well!
I've included the roofing as a token, for use with Foundry VTT's roofing system, added in 0.8.6.
As per usual, you can find all my Curse of Strahd battle maps and region maps available for free through the link below. The UVTT files are only available with the grid and lighting, but the battle maps themselves come with multiple variants - gridded and gridless, with and without lighting, full size (128 pixels or 256 pixels per square, map dependent) or 70 pixels per square.
