Complete roof replacements in LA range from $12,000 for standard asphalt shingles to $75,000 for tile or metal, with most projects completing in 3-7 days. On every replacement we strip the old roof down to the deck and replace the underlayment, so the new roof goes on a clean surface instead of on top of something we couldn't see.
We start by assessing your roof's current condition. Our experts check for leaks, ventilation issues, or damaged flashing and discuss any design preferences or special requests.
Outcome:
A clear overview of your roof's needs and a shared vision for your new roof.
We typically provide an itemized estimate covering materials, labor, and disposal fees. Permit fees are not included and may vary by local regulations.
Outcome:
A comprehensive cost breakdown, allowing you to make an informed decision with no hidden surprises.
Once you approve the quote, we'll coordinate a start date that fits your schedule. Shingles, underlayment, and other materials are delivered to your home in advance.
Outcome:
A firm timeline and readiness to begin work, ensuring minimal disruption to your routine.
Our team safely removes existing roofing materials and disposes of them responsibly. We then inspect the underlying roof deck and perform any needed repairs for a stable base.
Outcome:
A clean, damage-free foundation, ready for the next phase of installation.
We install high-quality synthetic underlayment to safeguard against moisture. Additionally, we apply ice and water shields around vulnerable areas like eaves, valleys, and chimneys.
Outcome:
A watertight barrier that protects your roof from leaks and extends its lifespan.
Licensed professionals install your Owens Corning® shingles, ensuring each layer meets manufacturer specifications. We also optimize ventilation (ridge vents, attic fans) for maximum efficiency.
Outcome:
A robust, energy-efficient roof that resists the elements and enhances your home's curb appeal.
Once installation is complete, we clear all debris and leave your property tidy. A final walkthrough ensures every detail meets Buildda's quality standards -and your satisfaction.
Outcome:
A quality finish and confidence knowing your new roof is built to last.
Buildda registers your Owens Corning® product warranty and our own 2-year workmanship guarantee. We also provide maintenance tips and answer any follow-up questions you have.
Outcome:
Official warranty coverage, clear aftercare guidance, and ongoing support for your investment.
