P.I. AUTO STORE ROOFMASTER Rooftop Cargo Carrier Bag Review

P.I. AUTO STORE ROOFMASTER is budget priced car rooftop cargo bag that provides you with 16 cubic feet of storage space – about the same as trunk of average sedan. Other similarly prices cargo bags are usually big on promises but short on follow-through – is that the case with ROOFMASTER as well?


Overall quality of P.I. AUTO STORE ROOFMASTER cargo bag is good, for the price it retails you could say it’s amazing. It feels pretty well made, sturdy and doesn’t show signs of wear after couple thousand miles of use.

It’s made of military grade nylon cordura fabric. It has kevlar thread stitching and heat welded seams which are absolutely necessary to make bag waterproof.

Other than that it has 1.5” wide straps, Duraflex buckles and generously sized flap with velcro that goes over zipper to prevent water getting inside.

Water resistance

Almost all cargo bags are waterproof according to manufacturer but in most cases, especially in this price category they really aren’t – yes, they are somewhat water resistant, but in some situations you will find that water has gotten inside the bag.

That doesn’t seem to be the case with P.I. AUTO STORE ROOFMASTER which seems to be actually waterproof as water fails to get inside the bag even after hours of continuous heavy rain. It seems like P.I. AUTO STORE ROOFMASTER is truly waterproof.


Cargo bag is easy to install and works whether you have a roof rack or not however if you don’t you have to buy door hooks separately.

Some have had problems with straps – it seems they might be too short for some vehicles and for some reason some also complained that they don’t stay tight and have to be retightened constantly.

For the money P.I. AUTO STORE ROOFMASTER is one of the best car cargo bags you can buy. Similarly priced cargo bags usually aren’t well made and might survive only couple trips, in worst cases they can even start to disintegrate on first use and although they are somewhat water resistant they aren’t quite waterproof. ROOFMASTER is one of the few bags that are exception to the rule – you don’t always get what you pay for, sometimes you get a lot more!

Surely, it’s not as good as some of the more expensive bags but those cost 2 or 3 times more and arguably doesn’t offer as good value for money as ROOFMASTER does.
