New roof installations
All Type construction specializes in new roof installations, ensuring durability and aesthetic appeal for your home. We use the best materials and techniques to deliver a roof that lasts. Our services include new shingles, guttering, and fascia to complete your roofing project.
Goal: Remove all old roofing down to the bare decking.
Steps:
1. Remove ridge caps first.
• Start at the top and work downward.
2. Tear off shingles:
• Use a roofing shovel or flat spade to pry up shingles and nails.
• Work in sections (about 4–6 feet wide).
3. Remove underlayment and flashing:
• Strip off old felt paper or synthetic underlayment.
• Remove step flashing and drip edge if damaged.
4. Clean the deck:
• Sweep off nails and debris.
• Inspect the existing sheathing for rot or delamination.
Goal: Replace or cover old decking with new plywood or OSB.
Steps:
1. Inspect all roof boards:
• Replace any soft or damaged wood.
• Check for solid nailing surfaces at rafters.
2. Lay new sheathing:
• Use ½” plywood or 7/16” OSB typically.
• Stagger the joints (brick pattern) for strength.
• Leave a ⅛” gap between sheets for expansion.
3. Nail securely:
• Nail to rafters using 8d nails or 2” screws.
• Nail every 6” along edges and every 12” in the field.
4. Trim and inspect:
• Cut sheathing to fit valleys, ridges, and edges.
• Check for level surfaces and tight nailing.

Goal: Create a watertight barrier before shingles go on.
Steps:
1. Install drip edge:
• Along the eaves first, then along the rakes later.
2. Apply ice & water shield:
• Lay 3–6 feet along the eaves, valleys, and around vents/chimneys.
• Overlap edges by at least 3”.
3. Install underlayment:
• Roll it out horizontally (parallel to eaves).
• Overlap each row by 4–6 inches.
• Staple or nail it flat without wrinkles.
4. Add flashing:
• Replace or reinstall valley metal, step flashing, and chimney flashing as needed.

l: Properly lay shingles for maximum life and weather protection.
Steps:
1. Starter strip:
• Install along the eaves first — this helps prevent leaks and blow-offs.
2. First shingle course:
• Begin at the lower edge, offsetting joints per manufacturer’s pattern.
3. Continue up the roof:
• Nail 1” above the cutout, 4 nails per shingle (6 in windy areas).
• Stagger joints as you go.
• Overlap each course properly (usually 5”–6” exposure).
4. Install ridge shingles:
• Use pre-cut ridge caps or cut from 3-tab shingles.
• Nail securely along the ridge line.
5. Seal and clean up:
• Use roofing sealant on exposed nail heads.
• Clean debris and check flashing one last time.
⸻
Goal: Ensure the roof is tight, aligned, and weatherproof.
Checklist:
• All nails properly seated and sealed.
• Flashing and vents watertight.
• Shingles straight and uniform.
• Ridge caps installed and sealed.
• Gutters and grounds cleane
