Residential Roofing: Asphalt Shingle Installation the Right Way
When it comes to protecting your home, your roof does more than keep you dry — it’s your first defense against Georgia’s storms, wind, and blazing sun. At L&L Roofing & Construction, we believe doing it right the first time is the only way. Here’s how we install asphalt shingles — the most common and trusted roofing system for homes in Gainesville and the surrounding areas.
1. Tear-Off and Prep
We don’t cut corners. Every job starts with a full tear-off of the old shingles, underlayment, and nails — not just a roof-over. Why?
- Roof-overs hide problems.
- Tear-offs allow us to inspect and replace rotted decking.
- It gives your new roof a solid foundation to last decades.
We also check for proper ventilation and moisture issues — both critical to the long-term health of your roof.
2. Decking and Underlayment
After the old materials are removed:
- We replace damaged or soft sheathing.
- Fasteners are reset or replaced.
- Then, we install a high-performance underlayment — typically a synthetic or asphalt-saturated felt — across the deck for moisture protection.
In colder areas or roof sections prone to ice dams, we install a peel-and-stick ice barrier membrane at the eaves.
3. Drip Edge and Flashing
Next, we install drip edge along eaves and rakes:
- Keeps water out of your fascia.
- Prevents wind-driven rain from getting under your shingles.
We also install or replace flashing around all penetrations — chimneys, skylights, plumbing vents — with corrosion-resistant metal.
4. Starter Strip Installation
We lay down a self-sealing starter shingle along the eaves. Why this matters:
- Prevents wind uplift on the first row.
- Seals the edge against leaks.
We never use cut three-tabs for this — it’s an outdated shortcut that doesn’t hold up.
5. Shingle Application
Here’s where craftsmanship meets code:
- We install architectural asphalt shingles from bottom to top, staggered properly.
- Each shingle is nailed with four to six nails depending on slope and wind requirements.
- We only use galvanized nails long enough to penetrate the deck.
We also ensure shingles are laid flat — especially in cold or hot weather where handling flexibility changes.
6. Ventilation and Ridge Cap Finish
A well-vented roof performs better and lasts longer:
- We install ridge vents or other ventilation as needed.
- Then we finish with pre-cut ridge cap shingles, sealing the peak and providing a clean look.
7. Clean-Up and Final Walkthrough
We treat your home with respect:
- Magnetic sweep to remove nails.
- Gutter and yard cleanup.
- Final inspection with the homeowner.
