I think the pair will through you a Blue Bar now and then but my advice to you is don't worry about the color at the moment. Lock in your roll no matter what color they are pair your best to best.
Just my two cents good luck.

I believe that the check pattern is dominate over the bar pattern. As such the only way to get bars is if your Cock bird is carrying bar, hidden by the check pattern. If this is the case then if you get a bar it most likely will be a hen.
I not a genetic expert by any means but I think this is right.
As far as breeding them together if they are your best put them together!!

With regard to pattern, each pigeon carries two genes. It inherits one from each parent. As you know, in rollers those pattern genes are T-check, check, and bar. The pigeon can be homozygous (both pattern genes the same), or heterozygous (different). If they are heterozygous, the dominant of the two pattern genes will show. RT is right that check is dominant to bar, and that if the check also carries bar (hidden by check), you will get some bar offspring. The hierarchy of dominance goes T-Check > Check > Bar. If a check is homozygous for check (both its genes for pattern are the same), then if mated to a bar, it will never parent a bar, only checks that are also carrying bar. If the check parent is heterozygous and also carries bar, and knowing that the bar parent is homozygous because bar is recessive to check, the probability of pattern for each offspring is:
A) 50% heterozygous showing check also carrying bar
B) 50% homozygous bar
If in a previous mating, the check parent has ever had a bar offspring, the check is heterozygous for check and also carries bar. If either of the check's parents were bar, then the check is heterozygous for check and also carries bar.
Pattern is an autosomal gene, not a sex-liked gene, and has no relationship with sex.

The only way to get all blue bar offspring from a blue bar hen is to mate her to a blue bar cock. However, mating her to an ash red bar cock carrying blue could also produce some blue bar offspring. The probabilities are:
1) 25% blue bar hen
2) 25% blue bar cock
3) 25% ash red bar cock, also carrying blue
4) 25% ash red bar hen
Or if the cock is either an ash red T-check or check also carrying bar, mated to a blue bar hen:
1) 12.5% blue bar hen
2) 12.5% blue bar cock
3) 12.5% ash red bar cock, also carrying blue
4) 12.5% ash red bar hen
5) 12.5% blue T-check or check (whatever applicable) hen, also carrying bar
6) 12.5% blue T-check or check (whatever applicable) cock, also carrying bar
7) 12.5% ash red T-check or check (whatever applicable) hen, also carrying bar
8) 12.5% T-check or check (whatever applicable) cock, also carrying bar
(help, I think I need to get a life)

I thought that Hens could not hide a pattern. or maybe it is just color? In that manner hens only carry one locus for pattern. I am new and just learning so I can be way off. or maybe that is just color?

it comes from what has worked for me, the wild type birds that i have have bread out the color of my birds,due to performance.
when im driving and i see someones flock and there is a lot of color,it is my asumption that they breed for such
