I walked in to ABC Supply today, July 15th of 2025. I usually get greeted and asked if there's anything I need help finding, but that wasn't the case today. Today, I saw a young employee on his cellphone texting. I didn't want to interrupt him, but I had no choice, as I didn't see the product that I usually buy when I walk in, Geocell Roofing Cement. I asked him where it was, but he told me that he didn't understand what I meant by "Roofing Cement," so I told him that it's also called roofing tar, and again, he told me that he doesn't know what I mean by that. He tried telling me that anything that goes on a roof is going to be a poly blend. This awkward conversation went on for a couple of minutes, as the guy felt strongly about contradicting me. Geocell literally named this stuff "Roof Cement." They even wrote it on the front of all of their tubes in large font. Roofing cement/ tar is literally the name that virtually all brands call this stuff, including Dap, Geocell, Black Jack, Kool Seal, etc. And, more importantly, roofing cement/tar is NOT a poly blend of any kind. It's petroleum based, made of coal byproducts. This ABC Supply employee did try to offer me a poly blend product that specifically states that it's for flashing. This stuff is usually silicone based, which sticks better to metal but worse to shingles. After he offered this to me, he then ask me what I'm trying to do on my roof. I told him that I'm trying to repair firework damage to my shingles. He told me that this stuff would work for that. Yeah, I'm not filling holes in my shingles with silicone, so I just went on Amazon and bought some tubes of Geocel Roof Cement.

No better supply house in the area! Julianna, Marshall, Doug and staff are always very pleasant, professional and knowledgeable. They make ordering a breeze and the drivers/delivery personnel are respectful, punctual and do a great job as well. Repeat customer and for very good reason! These guys are on it!

This is the most helpful ABC. Plus, their pricing on shingles is way better than other ABC's. Apparently, they are all different. I had a sales rep named Mark. Called him apparently he got promoted and only does commercial. Funny park is I was buying for commercial, everytime I asked he had a new excuse on qhy he couldn't help me anymore. The store told me to call him. He used to be great. If I were his manager, I would be pretty disappointed. If it wasn't for this store, I would have moved 100% of my business to Beacon. I keep some of ot at ABC longmont, but thanks to the amazing customer service of Mark, that 350 square commercial job went to another company. Longmont ABC helped to find me a new sales rep, so the new sales rep will get the next big job, but only because longmont ABC audits employees are so helpful. If my experience was only with Mark, I would have left ABC all together. Way to go, upper management. Maybe you should have promoted someone from this store instead. Customer and sales are about solutions, Mark is obviously above that now, but Longmont is not. If Mark is your salesman,don't bother. He is too good to help you now. Just come here. This store will take care of you.

The staff was pleasant, I was able to get in and out quickly. There was some confusion when I called. The first time I was told I could purchase something as a public purchase. The second time I called I was told they do not sell this item to the public. Probably just some training but I'm glad I got the first person because this was a an item I really needed to finish my roofing job.

I have used you guys for years.. an awesome place to get roofing materials peeps are usually very friendly..

Not today:

Nope, today: I'm giving you one star.

...And because of your negitive customer service today Shelly in Longmont.

So, i called looking for versetta stone. Right?

A brand of cultured stone..

Shelly answered the phone and said they didn't carry it.

Being as it was today that I learned from versettas direct that abc is infact a retailer for westlake,,

I was surprised when Shelly and her friend at the desk mocked and ridiculed me,
*corrected me with mis-information.*

I made sure to call shelly back, of course (after): I called abs denver to verify.

This is not how you increase sales people,..

... And Shelly; saying we have cultured stone but not versetta stone is like saying we have cars but not Toyotas.

Learn your product.

..and stop using your desk pals to mock clientele.

-we come to you to help find product.

Don't you have a computer right there in front of you?

Don't rely on ither people to do your job, do your own work.

Cause mabye they don't know ither..

And in this case you cheated off of someone else's paper and should not be surprised when you fail.

.. product sales is what keeps your bosses employing you

Isn't answering phones and helping people, what you do?

Then i dont know.. (mabye do it correctly)..

Or ... go flip burgers..

(Then again, you might not be good at that, ither.. After all: (not everyone knows you can get a whopper @ Burger King).

Hey so I went here because we were doing a roof that had 100 year old clay tile for the roof they had it I don't know what else I should say I think we got a fairly decent deal on an antique roofing system so I'm giving the high rating go with your contractor so you get the right thing the first time so you are not backing up just my thoughts

I CANNOT BELIEVE HOW RUDE THEIR "CUSTOMER SERVICE REPS ARE. I HAD CALLED IN NEEDING TO PLACE AN ORDER FOR PICK UP. THE GUY ON THE OTHER LINE KEPT INTERRUPTING ME. HE TOLD ME I WOULD HAVE TO CALL BACK ON MONDAY BECAUSE HE WAS SWAMPED. EVEN IF I WANTED TO TALK TO A MANGER, I WOULDN'T BE ABLE TO AS HE HUNG UP ON ME MID SENTENCE. I CAN ONLY IMAGINE WHAT MANAGEMENT IS LIKE, CONSIDERING HE WAS PROBABLY TRAINED TO WORK THIS WAY.

I'm a project manager for a roofing company here in town so I end up at ABC quite often. There's hardly ever been a place where you feel so welcome and greeted with friendly faces. Just today I came in feeling stressed out about a project but left feeling much better. Thank you ABC Supply.
