New roof jacks in existing asphalt shingle roof
 

I want to put in roof jacks for a solar heating unit, but my asphalt
shingle roof is a practically new dimensional shingle type roof, and
I'm afraid I'll get a leak or make an unsightly mess. I've seen home
builder shows make it look easy to remove a shingle or two, but I don't
understand how they can be replaced, especially above the roof jack.
