Yes Yes and Yes!! Russ I meet lots of guys that say there is no money in cleaning gutters, yet we have lots of residential gutter contracts that are great for December, but a pain in June! Commercial gutters can be big $$$. Also there is a guy here in MD with his MHIC and an experienced roofer so he gets lots of repair jobs as well. We recommend repairs all the time. I would guess at least half our roofs we recommend a repair at the ridge vent or on the penetrations. I find myself saying call a roofer to look at this or that almost every day.
