Anyone have any experience with Tamko Titan shingles?

Tamko is not a great shingle. The Titan is now a class 3 impact resistant shingle which is nice in theory but it really only meets that criteria because standards changed. It went from a bottom tier architectural to a class 3 by doing nothing. There are better options out there IMO. I like companies that are doing more innovative stuff with their shingle lines like Malarkey and Atlas.

I will say, Tamko holds up really well in wind, not so much to hail. They have a wide nail zone and have a strip on the back of their shingle that makes it feel glued on.

I'd personally ask your roofer if he puts on another manufacturer in addition to Tamko that might be an option.

I'm sure it will be fine, I've put on Tamko's before by homeowners request.

Honestly part of the reason that I'm not a Tamko fan as well though is that we've only installed a handful of them over the years and we've had two manufacturer default claims that Tamko had to make right. I've had two claims from Malarkey over the years but we've also put on probably 1,000 roofs

People will say a shingle is a shingle, any of them will work. Which is true to a certain extent, but some are better than others. But I'm in an area that installs 90% Certainteed, which is imo, the worst of them all. I will avoid ranting about certainteed since they weren't mentioned
