We are in the process of completing a reroof in MI. There are several large roof shingle manufacturers. In North Carolina….it seems CertainTeed and GAF are the predominant companies. In Michigan….at least in western Michigan….IKO and Tamko are the leading brands.
We received several proposals….some for IKO….some for Tamko.
One proposal was somewhat unique…. when the company owner started out the conversation by criticising the other manufacture. Not a good selling technique.
If a business has confidence in its product(s)….there is no need to criticise the competition. Let the company and its products/services stand on their own.
