The steps for an aluminum gutter installation are as follows:

 

• Measure the eave of the gutter to get the overall length. Be sure to include the outside edge of the shingles in the measurements for gutters that terminate at the gable end of the roof.
   

• Run a bead of sealant along the inside of the back, bottom, and face of the gutter at each end that is receiving an end cap or a miter piece.
   

• Attach the end caps and miters to the gutter using zip screws or rivets.
   

• Cut a hole in the bottom of the gutter that will allow for the installation of the outlet tube. Insert the outlet tube so that the flange of the outlet tube rests inside the gutter. Attach the outlet tube to the gutter with rivets or screws and apply a bead of sealant on the inside of the gutter.
   

• Start by fastening one end of the gutter to the fascia with a 1.5 screw. Typically, you should start at the point furthest away from the downspout. The back, top edge of the gutter should be level (at the same height) with the top of the wood fascia. 
   

• Use a level or a chalk line so that the gutter is pitched to drain towards the downspout. A 4 ft. level or chalk line can be used to pitch the gutter per 10 ft.
   

• After the gutter is pitched properly, the gutter hangers can be installed. Ideally, hangers get installed into the rafter ends with a 1.5 screw and placed approximately 24 apart. Hangers should be level across the gutter and be fastened through the top of the back of the gutter.
   

• Two elbows are often needed to allow the downspout to span the eave and to the house. The top (or higher) elbows should slip inside of the elbows and downspouts below (or lower) so that water is diverted directly to the piece below. Use the crimper (or pliers) on the bottom end of the elbow/downspout to allow it to fit inside the next piece. Use zip screws or rivets to fasten each elbow and downspout together.  
   

• Attach pipebands or pipe clips to the wall of the home using the 1.5 screws. We recommend two straps for most one story applications and 3 straps for most 2 story applications.
   

• Cut the downspouts and elbows down to the proper size using the tin snips.  
   

• Attach the downspout to the downspout straps with the zip screws or rivets.  
   

• Install an elbow at the bottom of the downspout (at grade) to divert water away from the foundation.  
   

• Install downspout extensions or splash blocks as necessary to get the water further away from the home.
