Step 9: Installing The Trim

Cut (6) pieces of trim item A and (6) pieces of trim item B. The only difference between the two is the direction of the angle.

Then cut (4) pieces of trim item C.

All the dimensions for the trim are longer than the final size because they will need to be individually cut to fit.

Nail 1 piece of trim A and B to each of the gable ends starting at the top center.

They will overhang quite a bit but you will trim them to fit later. Nail with galvanized nails every 6 inches.

Make sure the top edge of the trim lines up with the top surface of the OSB and not with the top edge of the siding. This 1/2 inch gap will be covered by the drip edge and shingles.

Take a piece of trim C and hold it firm to the bottom of the OSB and to the front gable trim piece. Mark the bottom and cut to length. Then nail the top 6 inches in place.

Take a piece of the front angle trim A or B and hold it in place flush to the edge of trim C and tight up to the gable end trim. Mark the bottom and cut to length. Hold in place and nail the top 6 inches.

Now line the corner edges of the two trim pieces up and nail from the top to the bottom being careful with the edge alignment.

Repeat for all corners.

Nail a full length piece of trim up under the eave tight to the bottom of the OSB. Cut the final eave piece to fit and nail in place. Repeat for the other side.

Mark and cut the excess off the gable end trim pieces. This trim piece will be shorter than the OSB roof sheeting but that gap will also be covered by the metal flashing and shingles.

This is what the final trim will actually look like.
