How To Build A Crown Roof

But it doesn t have to be.

How to build a crown roof.

A roof provides protection from the elements and precipitation helps drain water away from a structure and provides insulation that helps keep the interior of a building warm or cool depending on the season. If you begin with accurate as built measurements and use a construction calculator to do the math you can cut all of the rafters for most roofs on the ground in just one shot. Experience has shown that the weight of the roof will gradually flatten this crown. Start by overlapping a starter from both sides of the valley at the bottom.

This video will show you how to install roof shingles. Sink the heads to just below the wood surface using a nail sink or to make installation easier use a pneumatic nail gun to attach the molding and set the nails automatically. If there is any curve in the board lay out the rafter so the crown is up or facing away from you. The complex design requires more building materials and it s more difficult to construct.

This makes the bonnet roof more expensive than other more simple designs. Weave and cut the valley on the highest side of the roof. With a crown molding cornice a decorative layer of crown molding is added to the fascia and the roof extends to meet the upper corner of the crown. Cornice is just a fancy word for the eaves detail at the edge of a building where the roof meets the walls and on most houses it includes the soffit and the fascia.

Examine the rafter board to determine if there is any curve or crown in the board. You should make this first pattern rafter on the straightest board you can find. There are several types. This roof valley is a perfect example.

You want to lay the shingles from the bottom to the top of the valley. The next one goes on the low side. A roof is much more than just the decorative top of a building. Then draw a line using the roof slope angle.

Attach the trim to the walls and ceiling using 2 inch finishing nails driven at the studs and joists. Then your first shingle goes on the side you are going to cut.
