How To Shingle A Hip Roof With 4 Dormers? Eight Steps For Perfect Installation
The following details outline how to shingle a hip roof with 4 dormers.
Prep, Measure, And Guidelines
You need to verify that the roof deck is sound and the sheathing is securely nailed in place. Install drip edges along eaves first, then rakes. Snap vertical reference lines on every main slope to keep courses straight. Then, mark the exposure according to the shingle manufacturer’s specifications. You need to weatherproof the eaves, hips, and dormer tie-ins.
Field Underlayment
Now, cover the remaining deck with synthetic underlayment and overlap the courses as specified. Wrap dormer roofs also with proper overlapping onto the main slope.
Begin With Starters
Now, start installing the starter strip along all eaves of the main roof and each dormer roof. Then, use an adhesive edge at the eave. You can also add starters up the rakes if your shingle system needs it, especially on windward edges.
Shingle The Lowest Main Slope First
Start at the lowest eave on the largest slope. Nail with the specified pattern. Then, stagger end joints according to the manufacturer’s offset.
Integrate Dormers When You Climb
When you reach the dormer, follow the given steps.
- At the lower dormer side, you need to install kickout flashing to divert water into the gutter.
- Lay one shingle course and set a step flashing piece on top, and nail the flashing to the roof deck. Now, cover it with the next shingle and repeat this procedure up the sidewall.
- You need to install continuous headwall flashing at the dormer top that laps over the last course of shingles below.
- Tuck flashing behind siding or add counterflashing on the mansory.
Shingle Dormer Roofs
Then, you need to install starters at the dormer eaves, field shingles up to the dormer ridge. And treat dormer rakes like any rake edge. Maintain straight lines with chalk.
Form Closed Cut Valleys At Dormers
For a closed cut, run shingles through on the less-visible plane. Lay the opposing plane, then snap a line 2 in from the center and cut. You need to seal the cut edges with roofing cement. For open metal valleys, center metal, hem edges, and keep fasteners outside the valley line. Complete all main slopes shingling to maintain stagger and nail placement. Keep courses by checking against your snapped lines. You also need to cap your hips and ridges for a smooth finish.
