## How to Replace a Shingle Roof — What Owensboro Homeowners Should Know

Searching for **how to replace a shingle roof**? Whether you're thinking about tackling it yourself or just want to understand what a contractor is doing on your home, this guide walks through the full process. We'll also be straight with you about when DIY makes sense and when it doesn't.

### The Roofing Process Step by Step

Here's the **roofing process step by step** for a standard asphalt shingle replacement:

**1. Safety setup**
Ladders, roof jacks, and fall protection. This is where most DIY injuries happen. Don't skip it.

**2. Tear-off**
Remove all old shingles, underlayment, and damaged flashing. Use a roofing shovel or shingle ripper. Work from the ridge down. Dispose of debris properly — a dumpster or trailer is essential.

**3. Deck inspection**
Walk the deck and look for soft spots, rot, or damaged sheathing. Replace any bad sections with matching OSB or plywood.

**4. Drip edge**
Install metal drip edge along the eaves first, then along the rakes after underlayment is down.

**5. Ice and water shield**
Apply self-adhering membrane at the eaves (minimum 24" past the interior wall line), in all valleys, and around penetrations.

**6. Synthetic underlayment**
Cover the rest of the deck with synthetic felt, overlapping courses by at least 4".

**7. How to start shingles on a roof**
Install a starter strip along the eaves — this is a full shingle with the tabs cut off, or a purpose-made starter product. It seals the bottom edge and prevents wind uplift. Overhang the eave by 1/4"–3/4".

**8. Field shingles**
Work up the roof in a stair-step pattern. Nail each shingle in the nailing zone (not too high, not too low). Use 4 nails per shingle minimum; 6 in high-wind areas.

**9. Valleys**
Cut shingles to the valley line. Use open, closed, or woven valley technique depending on the situation.

**10. Flashing**
Step flashing at walls, counter flashing at chimneys, pipe boots at penetrations. This is where most DIY roofs fail.

**11. Ridge cap**
Install ridge cap shingles from one end to the other, nailing in the correct zone.

**12. Cleanup**
Magnetic nail sweep, debris removal, final inspection.
