I am going to be re-roofing a small shed. I plan to use the GAF Grand
Timberline 50 year architectural shingle. I have several questions:

I have read that I should use a "starter" course along the eaves and rakes
of the roof. But, the book that I am reading says that this starter course
should be a 3-tab type shingle. Why is this ??

I don't see a 3-tab shingle at the GAF website that comes in the same color
as the architectural shingle that I would like to buy. (I guess it
doesn't matter much if the starter rows would all be covered up anyhow ??)

I am thinking of using another brand, and they also say use 3-tab on
the start, but since it is covered, as you say, you could use any
color.

Here's their installation instructions if you care.

For a small shed, though, I really think you are doing overkill with a
50-year singe and then using weathershield....of course it's your $$$.
I just roll roof my shed.
