Understanding the Full Roof Replacement Process

Introduction: Why Knowing the Process Matters

Replacing your roof is one of the most important investments you'll make as a homeowner. It protects your home from the elements, maintains your home’s structural integrity, improves energy efficiency, and enhances curb appeal. But for many homeowners, the process can seem overwhelming.

At K&M Roofing and Construction, we believe an informed homeowner is a confident one. This comprehensive guide will walk you through each stage of the roof replacement process, from inspection to installation and beyond. Whether you're in North Texas, Central Texas, or the Austin area, this is everything you need to know before the first shingle is removed.

Step 1: Roof Inspection and Project Scope

Every full roof replacement starts with a thorough roof inspection. A trained roofing specialist will assess the current state of your roof, looking for:

• Missing or curling shingles
• Soft spots or sagging
• Leaks or water stains
• Flashing damage
• Granule loss

They'll also inspect your attic ventilation and insulation to ensure your roofing system performs efficiently.

Once the inspection is complete, you'll receive a detailed project scope, including:

• Type of materials recommended
• Estimated labor and material costs
• Timeline for project completion

Homeowners are often surprised by what a trained eye can detect. Even if your roof looks intact from the ground, minor issues like poor ventilation or hidden leaks can lead to long-term problems. That’s why an early inspection is so critical—not only for budgeting but also for protecting your property.

Step 2: Choosing Your Roofing Materials

Next, you’ll choose the roofing material that fits your budget, style, and climate needs. At K&M Roofing, we offer:

• Architectural asphalt shingles for durability and wind resistance
• Impact-resistant shingles perfect for Texas hail storms
• Energy-efficient options with solar-reflective granules
• Designer shingles that elevate curb appeal

We proudly use Owens Corning® products and offer guidance on selecting the best warranty and color options for your home.

When choosing materials, homeowners should consider longevity, warranty options, and how the color complements their home’s exterior. For example, darker colors may help with snowmelt in colder climates but can increase attic temps in Texas summers. Lighter shingles reflect more sunlight, helping to keep your energy bills down.

Step 3: Permits, Scheduling, and Preparation

Once materials are selected and the contract is signed, we handle the logistics:

• Permit application through your city or HOA
• Material and dumpster delivery a few days before the project
• Scheduling based on crew availability and weather conditions

You’ll also receive a prep checklist to:

• Move vehicles from the driveway
• Secure pets and remove lawn items
• Notify neighbors about the project timeline

Communication is key during this phase. We keep you informed every step of the way and assign a dedicated project manager who coordinates materials, crew arrival, and inspections. This pre-planning stage ensures fewer delays and a smoother process overall.

Step 4: Removing the Old Roof

The tear-off phase begins early on installation day. Our crews remove all old materials down to the decking, including:

• Shingles or tiles
• Underlayment
• Flashing

Why a full tear-off?

• It reveals hidden damage to your roof deck
• Ensures the manufacturer warranty stays valid
• Allows proper installation of modern roofing systems

We place protective tarps and use magnetic rollers throughout the job to catch stray nails and debris.

This stage often surprises homeowners with how fast it moves—but it's also one of the loudest and messiest parts of the project. That’s why we prioritize property protection from the very start.

Step 5: Repairing the Roof Deck and Flashing

With the roof stripped, we inspect the wood decking underneath. If needed, we replace:

• Rotten or mold-damaged plywood
• Plank decking that fails modern spacing standards

We also install or replace critical components like:

• Drip edge flashing
• Ice and water barriers in valleys
• Chimney and vent flashing
• Ridge vents or static vents

Flashing, in particular, is essential for waterproofing. Many leaks originate where the roof meets vertical surfaces, and quality flashing prevents those issues before they start. Our team uses only top-rated materials and sealants to create watertight protection that lasts.

Step 6: Installing Underlayment and Shingles

This is the heart of the project. Once your decking is solid, we start layering your new roofing system:

1. Synthetic underlayment for full-deck moisture protection
2. Starter shingles along the roof’s edge for wind protection
3. Main shingles, installed in overlapping rows for weather sealing
4. Ridge cap shingles to seal hips and peaks
5. Roof vents, either replacing or upgrading attic ventilation

Every step is completed following manufacturer specs to ensure long-term performance and warranty compliance.

Our installers are certified and trained regularly to stay updated on evolving product technologies and installation best practices. The precision at this stage impacts your roof's performance for decades to come.

Step 7: Project Clean-Up

We take jobsite cleanliness seriously. Once the installation is complete, our team:

• Blows off roof and gutters
• Rolls the yard with a magnetic nail sweeper
• Removes debris and dump trailers
• Leaves your property cleaner than we found it

Your peace of mind is our priority. That’s why we also offer a final homeowner walk-through before you sign off.

Homeowners with pets and kids especially appreciate our emphasis on cleanliness. We go the extra mile to make sure your yard is safe and nails are accounted for. You shouldn’t have to clean up after your roofer.

Step 8: Final Walkthrough and Warranty Handoff

Before we consider any job complete, we:

• Conduct a detailed inspection of the finished roof
• Review warranty documents with you
• Answer any last-minute questions
• Discuss long-term care and maintenance plans

Your satisfaction is guaranteed. We back our work with manufacturer and labor warranties and offer seasonal maintenance advice.

We also remind homeowners of routine maintenance tasks—like keeping valleys clear of debris and scheduling seasonal inspections. A good roofing system is built to last, but smart upkeep extends its life even more.

How Long Does Roof Replacement Take?

On average, a full roof replacement takes 1–3 days. Larger, steeper, or more complex roofs may take up to a week. Here’s what influences the timeline:

• Roof size and pitch
• Weather conditions (rain or wind can delay work)
• Type of materials (tile and slate take longer than shingles)
• Structural repairs or decking replacement
