Full cover or pergola on patio

Hi all,
I have a patio I'd like to cover, but I'm not sure whether a full cover or pergola is what I want/need. My main reason for the cover is shade, but for those few days we get rain it would be nice for a full cover. Also cost is an issue. I'm confident that with my current skill level I can put up a pergola myself, but if I go with a full cover I'd like to make it seamless with the roofline and shingle over it... which I'd need a contractor to do.
At any rate, can who's gone down this road through out some pros and cons of either? I know there are very few cons to a full cover, but has anyone gone with a pergola and totally regretted it?
Thanks for any comments or suggestions. The patio right now is only about 10'x8', but I'm planning expanding it to maybe 20'x15' or so (still not sure on dimentions since I'm not sure where my septic lines run).
Take care,
Alex.

There are cons, or at least caveats, with the full covering. (1) Slope. If the patio cover is too flat you'll face leaks where it meets the house roof, no matter how hard you try to prevent them. (It's because in heavy rains the water will actually run "uphill," that is, backs up because of the slow run off, and can wick UNDER your new shingles.
(2) Architecture. You want this new patio roof to "fit" with the house, and not look cheesy. Ideally, this means continuation of the facia board from house, out around the patio, then returning back to house in one horizontal line. You don't have to do it this way, but it helps to think about the architecture before you start.
(3) Ceiling height and shape where porch meets the house soffit. This could mean lowering joists, or else, stepping them up....etc.
Cons with pergola fall mainly on the nails and nail points. I've seen cedar which is fairly weather resistant rot on pergolas where the nails have allowed rain to enter the wood. This is especially true where joists rest on beams and are toenailed. Rain seeps in and sits there. Kinda hard to prevent this by design. Don't expect paint to prevent this.
Also, I've never seen pergolas as a means of providing much shade. But it's decidedly going to be the cheapest to build.
Good luck!
