The Professional Roof Installation Process.

Quality roofing starts with quality installation. Eight stages of manufacturer-spec methods that protect your warranty and your long-term performance.

Capital City Roofing 5-step precision installation process: tear-off, deck inspection, synthetic underlayment, shingle installation, final inspection and cleanup
Installation day: what to expect - clean tear-off, precision installation, final cleanup and inspection

Every Capital City Roofing installation follows our certified, manufacturer-specified process.

The Process

Eight stages, documented.

01

Pre-installation preparation

Before work begins, our team conducts a final site assessment as part of our 27-point full home inspection, evaluating roof, gutters, siding, fascia, soffit, attic, foundation, and driveway. We position dumpsters strategically, lay protective tarps, and review the project plan with you.

Key actions
  • Dumpster positioning and property protection
  • Final walkthrough with project manager
  • Material delivery and staging
  • Safety equipment setup
02

Complete tear-off

We perform a complete tear-off down to the roof deck, removing all old shingles, underlayment, drip edge, and flashing. This allows full inspection of the deck and ensures a clean foundation. Partial tear-offs or layovers void manufacturer warranties.

Key actions
  • Remove all existing roofing materials
  • Inspect roof deck for damage or rot
  • Document deck condition with photos
  • Load debris into dumpster continuously
03

Deck inspection & repair

With the old roof removed, we thoroughly inspect every square foot of decking. Any damaged, rotten, or sagging plywood is replaced with new 7/16″ or 1/2″ OSB or plywood. Deck integrity is the foundation your entire roofing system relies on.

Key actions
  • Inspect 100% of roof deck surface
  • Replace damaged or soft decking
  • Secure loose boards and re-nail as needed
  • Document repairs with before / after photos
04

Drip edge & ice-and-water shield

We install metal drip edge along all eaves and rakes. Ice-and-water shield (a self-sealing waterproof membrane) is applied to all valleys, eaves, rakes, and around penetrations like chimneys and skylights, critical areas where leaks commonly occur.

Key actions
  • Install drip edge on eaves and rakes
  • Apply ice-and-water shield to valleys
  • Protect eaves (minimum 3 feet from edge)
  • Seal around all penetrations
05

Synthetic underlayment

We install premium synthetic underlayment across the entire roof deck. Synthetic is stronger, more tear-resistant, and provides better waterproofing than traditional felt paper. This layer is your roof's secondary water barrier.

Key actions
  • Roll out synthetic underlayment horizontally
  • Overlap seams per manufacturer specs
  • Secure with cap nails or staples
  • Ensure complete deck coverage
06

Shingle installation

Shingles are installed following manufacturer-specified nailing patterns and exposure rates. We use 4–6 nails per shingle (depending on roof pitch and wind zone) with proper alignment and overlap. Starter shingles are installed along eaves and rakes to prevent wind uplift.

Key actions
  • Install starter strip along eaves and rakes
  • Lay shingles with proper exposure (5–5.5″)
  • Follow manufacturer nailing patterns
  • Maintain straight lines and proper alignment
07

Ridge venting & flashing

Proper ventilation is critical for roof longevity and energy efficiency. We install ridge vents along the peak to allow hot air to escape. All flashing around chimneys, skylights, and wall intersections is replaced with new, properly sealed flashing.

Key actions
  • Install ridge vents for proper airflow
  • Replace all pipe boots and flashing
  • Install step flashing at wall intersections
  • Seal all penetrations with roofing cement
08

Cleanup & final inspection

We run magnetic nail sweeps across your entire property multiple times to collect metal debris. All tarps are removed, landscaping is checked, and the dumpster is hauled away. Our project manager conducts a final inspection with you, reviews warranty documentation, and answers questions.

Key actions
  • Magnetic nail sweep (3+ passes)
  • Remove all debris and tarps
  • Final walkthrough with homeowner
  • Provide warranty documentation

FAQ

Installation questions.

How long does a typical roof installation take?

Most residential roof replacements are completed in 1–2 days, depending on the size and complexity of your roof. A standard 2,000 sq ft home with a straightforward gable roof typically takes one full day. Larger homes, complex roof designs, or projects requiring extensive deck repair may take 2–3 days. We'll provide a detailed timeline during your estimate and keep you updated via BuilderLync.

What happens if it rains during my roof installation?

We monitor weather forecasts closely and won't start a tear-off if rain is imminent. If unexpected weather occurs mid-project, we have tarping systems ready to protect your home immediately. Our crews carry heavy-duty tarps and can secure your roof within minutes. We complete the tear-off and underlayment installation in a single day, so your home is weatherproofed before we leave.

Will I need to be home during the installation?

You don't need to be home during installation, though many homeowners prefer to be present for the initial walkthrough and final inspection. Our project manager will meet you before work begins to review the plan, answer questions, and establish communication. Throughout the day, you'll receive BuilderLync updates with photos and progress notifications.

How do you protect my property during installation?

Property protection is a top priority. We place tarps over landscaping, deck areas, and entry points. Magnetic nail sweeps are run across your entire property multiple times to collect metal debris. Dumpsters are positioned to minimize lawn damage and are removed promptly. We leave your property cleaner than we found it.
