Having watched this forum for a while, I don’t blame the moderators for addressing advertising on the forum. That can get so out of hand.
I would recommend that you make some informative posts that include the sources of the data you provide. I can get the information I need straight from the source. If you can save me time or be more effective, then I would know that by comparing the labor intensive method I use to your product.
Those are just ideas, but if I wanted the favor of the moderators, I would get the favor of the roofers. Those moderators seem very sharp to me. If you start posting stuff that can help us, I will bet they will let you put in a plug at some time.
By the way, I did read your post that was deleted, and I am sorry to say that I would have deleted it, too. It seemed just like a sales ad, that would be listed as spam on any reputable forum like this. No offense, please, I am just trying to clear things up, OK?
