For most homeowners, a roof replacement isn’t something you do often — maybe once or twice in your lifetime. So, when it’s time, it’s natural to wonder what to expect.
At EAS Roofing, we’ve helped thousands of Pittsburgh and Western Pennsylvania homeowners replace their roofs with confidence. Here’s a step-by-step look at what really happens during a professional roof replacement — and how the process protects your home for decades to come.
1. The Initial Roof Inspection
Every roof replacement starts with a detailed inspection. Our certified roofing specialists check for leaks, missing shingles, flashing damage, attic ventilation issues, and any soft decking that needs repair.
For homeowners in areas like Glenshaw, Wexford, and Peters Township, Pittsburgh’s mix of heavy snow, ice, and summer storms can accelerate wear — so a thorough assessment ensures we know exactly what your roof needs before installation day.
2. Tear-Off and Property Protection
On installation day, we start by protecting your property. At EAS Roofing, we use tarps, a Catch-All system, and an Equipter when possible, to shield your landscaping, siding, and driveway from debris.
Once everything is covered and safe, our crew removes every layer of your old roofing system — not just the top shingles. We take it down to the roof decking so we can start fresh with a solid foundation.
3. Deck Inspection and Repairs
After the tear-off, we inspect the roof decking for rot, nail pops, or water damage. Any soft or damaged wood is replaced to ensure your new roof has a sturdy base.
This step is especially important in older Pittsburgh homes where past leaks or ventilation issues might have weakened the decking.
4. Weatherproofing and Underlayment Installation
Next, we install waterproof barriers that protect your home from the region’s freeze-thaw cycles.
- Ice & Water Shield: Installed along eaves, valleys, and around penetrations to prevent leaks from ice dams or heavy rain.
- Synthetic Underlayment: A moisture-resistant layer that provides extra protection between your decking and shingles.
These layers work together to keep your home dry year-round, even during Western Pennsylvania’s unpredictable weather.
5. Flashing, Ventilation, and Drip Edge
Proper ventilation and flashing installation are key to a roof’s longevity.
We install new flashing around chimneys, vents, and valleys, and replace all drip edges to keep water directed away from fascia and siding. We also ensure your attic has balanced airflow — an essential part of preventing heat buildup and extending the lifespan of your shingles.
6. Shingle Installation
Now comes the exciting part — your new roof!
We install CertainTeed’s Integrity Roof System®, which includes high-quality shingles, starter strips, ridge caps, and proper sealing. Our crews follow manufacturer guidelines down to the nail pattern, ensuring your roof is eligible for its full 50-year non-prorated warranty.
7. Cleanup and Final Walk-Through
Once the last shingle is nailed down, our job isn’t done yet.
We perform a complete cleanup, removing all debris and sweeping your property with magnetic rollers to catch any stray nails. Then we will do a final walk-through with you to review your new roof and make sure every detail meets our quality standards.
