Recently got back into shingles after 25+ years away.
Also getting back into single-ply after 20 years away. Got forced into a 295 SQR job for an existing customer - his bank is insisting that she do what the adjuster paid her to install after hail damage. So it's either pull the trigger on TPO or risk losing the customer.
We are getting into TPO for the same reason we got into SPF years ago - not because we think it's a great system, but because that is where the market has gone in our area. Might also offer IB as an upgrade.
We got into SPF because I got tired of ignoring what customer wants. Same thing with TPO.
Trump knows how the game is played, it's how he amassed his fortune. Obama was a simple clown, elected by emotion-driven people who wanted to make history rather than electing the best person for the job.
