You’ve realized it’s time for a roof replacement. So, how is a new roof installed? A lot of home owners are curious how this process works so they can understand where their investment is going. Great question! At BCM Roofing, with over 20 years of experience, we’re happy to walk you through the process of how a new roof is installed step by step.
How We Install a New Roof
PRE-INSTALLATION PREPARATION
Most roofing jobs only take one day to complete. Our team begins by thoroughly evaluating your existing roof for structural soundness and identifying any underlying issues. Safety measures are then implemented, including scaffolding and tarps to protect your property during installation.
ROOF TEAR-OFF
The old roofing material is carefully removed to expose the roof deck. This allows us to inspect the underlying structure for any damage or rot that must be addressed before continuing.
ROOF DECK INSPECTION & REPAIR
The roof deck, typically made of plywood or oriented strand board (OSB), serves as the foundation for the entire roofing system. We inspect it for damage and replace or repair any compromised areas, ensuring a stable base for your new roof.
UNDERLAYMENT INSTALLATION
A protective underlayment is applied over the roof deck to serve as a moisture barrier. Common types include felt paper, synthetic materials, and ice shields, all designed to add protection against leaks and water infiltration.
STARTER STRIPS & DRIP EDGE
Specially designed starter strips are installed along the eaves to create a watertight seal and ensure proper shingle alignment. A drip edge—a metal strip—is also installed along the eaves and rakes to direct water into gutters and prevent water damage to the deck.
NEW SHINGLE INSTALLATION
We install your chosen roofing material, whether it’s three-tab shingles for a traditional look, architectural shingles for added durability, or luxury shingles for a premium finish. All materials are installed following manufacturer guidelines to ensure long-lasting performance.
INSTALL VENTILATION & RIDGE CAP
Proper ventilation is critical to extending the lifespan of your roof. Ridge vents, soffit vents, and gable vents are installed to promote airflow and prevent moisture buildup. Ridge caps are placed along the roof’s peak, providing a finished appearance while protecting against wind and water infiltration.
FLASHING INSTALLATION & GUTTERS
Some flashings—such as step flashing around walls or chimneys—are installed in tandem with the shingle courses to create a seamless seal. Once shingling is complete, we add counterflashing where needed to ensure thorough protection against water infiltration. Gutters and downspouts are also readjusted at this stage to restore roof drainage unless new gutters
are being installed.
FINAL INSPECTION & CLEANUP
We conclude the process with a detailed final inspection to ensure the entire roofing system meets our high-quality standards. The worksite is thoroughly cleaned, with all debris removed, leaving your property looking better than ever with your new roof ready to protect your home for decades.
WARRANTY & MAINTENANCE
After the roof is completed, we provide guidance on care and upkeep to maximize its longevity. We also confirm any warranty details and remain available for post-installation inquiries, ensuring you have peace of mind with your new roof for years to come.
New Roof Installation Conclusion
In summary, a new roof installation is a major job that takes the right tools, careful planning, professional expertise and a hardworking team to get it done quickly and correctly.
