Replacing your roof is one of the largest home renovations you’ll ever undertake—and the most crucial. It may be due to age, wear and tear, or just to enhance curb appeal, but a full roof replacement is more than installing new shingles. It’s a whole system of components that work together to defend your home for decades to come.
Be sure you have a comprehensive roof replacement checklist before you start to prevent surprise expenses or cuts that might result in expensive roof leak repairs down the road. Let’s dive into the 9 essentials every homeowner should hire for a successful, complete roof replacement—plus expert advice for long-term upkeep and protection.
1. Roof Decking: The Structural Base
The roof decking, also known as sheathing, is the foundation layer that supports the remainder of your roofing products. It’s generally constructed of plywood or OSB (oriented strand board). When decking has been damaged or is rotten, it will have to be replaced during your home roof replacement.
Why It’s Essential:
- Offers the structural basis for underlayment and shingles.
- Degradation can lead to sagging, uneven surfaces, or even collapses.
- Should be replaced in the event of mold, rot, or water damage.
Roofing Tip: Have your contractor inspect decking during tear-off. Soft spots or discoloration are telltale signs.
2. Drip Edge: Guarding the Perimeter
Most often overlooked but absolutely necessary, the drip edge is a metal flashing that runs down the edges of the roof. It directs water into the gutters and prevents it from seeping into the fascia or underlying materials.
Benefits of Drip Edge:
- Saves wood rot, ice dams, and shingle curl.
- Mandated by building codes in most states, including Pennsylvania.
- Extends the overall life of your roof.
Drip Edge Tip: Local climatic conditions with heavy rain showers make certain drip edge installation on all replacement projects.
3. Ice and Water Shield: Protecting High-Risk Areas
An ice and water shield is a self-adhering, waterproof membrane that is installed under the shingles in vulnerable locations—such as chimneys, eaves, and valleys.
Key Advantages:
- Works as a wind-driven rain and ice dam stopper.
- Seals around nails to avoid leaks.
- Particularly important for stormy or freezing areas.
Roof Leak Repair Tip: Install top-quality shields on roof edges and in valleys to avoid future harm.
4. Roofing Underlayment: Your Backup Barrier
Laid directly on top of the decking, the underlayment provides an extra layer of protection between your home and the elements. It comes in old-fashioned felt and newer synthetic varieties.
What to Keep in Mind:
- Felt underlayment: Inexpensive and water-resistant.
- Synthetic underlayment: Light, puncture-resistant, and long-lasting.
- Won’t leak when shingles are cracked or displaced.
Bonus Tip: Opt for synthetic if you desire additional heat resistance and longevity.
5. Starter Shingles: Setting the Foundation
Starter shingles are put on at the roof edge before the usual shingles. They assist in keeping down the initial row of shingles and prevent them from being blown up under windy weather.
Why Starter Shingles Matter:
- Offer a snug fit on eaves and rakes.
- Decrease the opportunity for water intrusion.
- Critical to proper shingle positioning and wind defense.
Roof Maintenance Tip: Incorrect starter shingle placement is a major reason for premature roof failure—be certain your contractor includes them.
6. Roofing Shingles or Main Materials: The Core Protection
The exterior and most noticeable part of your roof. Proper shingles or roofing material can make a difference regarding durability, beauty, and affordability.
Common Options:
- Asphalt Shingles: Most prevalent and budget-friendly.
- Metal Roofing: Durable and energy-saving.
- Slate or Tile: Sophisticated, long-lasting, and very expensive.
When selecting materials to replace your home roof, consider your region, building type, and warranty. Your local, reputable builder such as Yeager Home Improvement, LLC will be able to recommend the best solution for your house and finances.
7. Ridge Cap Shingles: Sealing the Roof Peak
Ridge caps are specially constructed shingles to cover over the ridge or peak of the roof, where two slopes intersect. They’re more than a nice trim piece—they seal one of the most exposed areas on your roof.
Key Benefits:
- Prevent water and debris entry at the peak.
- Generally ventilated to provide attic ventilation.
- More durable than regular shingles when placed in this location.
Home Improvement York PA Tip: If your old roof didn’t have enough ridge caps, an upgrade can greatly enhance ventilation and leak prevention.
8. Roof Ventilation: Ensuring Airflow
Good ventilation is critical to the performance and longevity of your roof. It controls attic temperatures and prevents moisture accumulation.
Types of Roof Vents:
- Ridge vents
- Box vents
- Turbine vents
- Soffit vents
Why It Matters:
- Reduces summer heat and winter condensation.
- Increases longevity of shingles and underlayment.
- Helps save energy costs.
Roofing Tip for Repair: Ventilation is out-of-sight danger—have your roofer check out ventilation on replacement.
9. Pipe Boots & Flashing: Sealing Penetrations
Pipe boots and flashing are installed to fit around chimneys, vent pipes, and other roof penetrations to prevent water entry.
Common Materials:
- Aluminum
- Rubber
- Galvanized steel
Functions:
- Seal joints and edges that leak.
- Direct water away from seams and openings.
- Needed to avoid permanent water damage.
Roof Leak Repair Tip: Flashing is generally the first to disappear on older roofs. Always replace flashing and pipe boots in your full roof replacement. For premium installation, Yeager Home Improvement, LLC guarantees all flashing parts are in compliance with modern roofing standards.

- Roofing nails and fasteners: Install corrosion-resistant nails to extend roof life.
- Sealants and adhesives: Critical for bonding and leak protection.
- Building code compliance: Your builder must comply with all local York PA regulations in order to qualify for insurance coverage and inspection approval.
Key Takeaways:
- Always work with a licensed contractor who uses quality, code-compliant materials.
- Don’t leave out “invisible” items like underlayment, starter shingles, and flashing.
- Regular inspections and roof maintenance tips like clearing gutters and checking ventilation can extend your roof’s life by years.
