Made for the northern climate we generally install .032 5" seamless aluminum K style gutter which is run off from a 12" wide coil. This is a typical/common gutter for your residence as well as the most affordable.
We secure the gutter using heavy duty hidden brackets which are engineered with quality, strength and reliability to supply the support it needs with a clean look. Brackets are spaced no more that 24" apart for more durability. We then seal all gutter seams using commercial grade sealant.
Downspout size typically recommended for this application is 2x3, 3x4 is also available. Standard colors are white and brown. Custom colors available upon request.
