It is getting near time for a new roof. I have a medium blown color

What is a good long lasting brand of fiberglass/asphalt shingle? Do
roofers typically charge more for a roof with a steeper slope (45
deg). Thanks

Before you decide, drive around an look at the lighter-colored roofs in your
vicinity.

If they don't look stained, streaked, and just plain disgusting, you might
be okay.
