Roof skylights illuminate the interior and add living space in the attic. To convert the attic into a bedroom or other dwelling, it is important to build at least two roof dormers for ventilation and to reduce humidity. There are different styles of skylights, from curved to polygonal, and you can choose according to the desired design.
Step 1 – Map the design
Illustrate the design on a paper to estimate the size of the dormers and to help you estimate the cost of your project. Visit a supply store with the draft to get the required amount of supplies.
Step 2 – Put your artwork on a visible floor
Draw the plane of the window on the attic floor near the place where you want to open. The diagram should be plumb. Insert a nail on each corner of the roof with the measurements you have taken. Make the outline of the sides using a plumb bob to direct yourself and draw straight lines with chalk. If the cut touches the rafters, hammer a 2 'x 4' bracket up and down that will be in place until you attach the new rafters to the recessed roof.
Step 3 – Prepare the surface
Place the ladder against the side of the roof on which you will be working. Attach all the carpenter's tools to the tool belt and attach the safety harness to a higher ground, such as a tree. Install the scaffold as a support, then climb on the roof. Trace the line with the help of nails that extend from the inside. Remove the shingle on this section and cut that part off the roof.
Step 4 – Create the wall
Attach new rafters to the revealed edges. Press the nails to six inches and check the level. Have the same number of new chevrons in the same position and number as the first. Lay four 2×4's on the illustration you made on the floor and push the nails on all sides to form a square. Inside the square, trace the opening of the window and use the steps to cut the wood. Place them on the window and place the new recessed roof wall in its place. Adjust the top plate on both sides with wood to join the wall to the roof. Place the level on the top plate to make sure it is level. Measure the distance between the top plate and the edge of the roof, and mark it at least six inches. Cut the wood to measure and fix the posts on this side of the wall on the marks you made.
Step 5 – Fix the rafters
Attach a ridge board by measuring the distance between the end of the opening and the new wall. Place the sloped rafters from the ridge board to the top plate. Add two studs that go from the last rafters until the window opens.
Step 6 – Sheathe the Surface
Measure the size of the new roof and sides and cut out the pieces of plywood needed. Place them on the structure and place the waterproofing membrane on the sides where the new wall meets the old roof.
Step 7 – Final Touches
Place the felt on the new roof with the help of the adhesive. Give it a few minutes and attach the metal valley to the joint between the end of the rafters and the old roof. Place the shingles on the felt and secure the window in the opening.
