Our business was built on honesty, reliability, and attention to detail—values that continue to guide us on every roofing replacement we complete.
When Is It Time for a Roofing Replacement?
Most asphalt shingle roofs last between 20 and 30 years depending on climate, ventilation, and material quality. According to the National Roofing Contractors Association, homeowners should have their roofs professionally inspected at least twice per year to identify potential issues before they escalate. If your roof is approaching or has exceeded its expected lifespan, recurring leaks, missing shingles, granule loss, and sagging decking are all strong indicators that a full replacement is the most cost-effective solution. Continuing to pour money into an aging roof often results in greater expense over time compared to investing in a new system.
Other signs that warrant replacement include widespread moss or algae growth, visible daylight through the roof boards, and damaged or deteriorating flashing around chimneys and vents. Homeowners in San Rafael, Novato, San Anselmo, Larkspur, Corte Madera, Greenbrae, & Mill Valley, CA also face unique weather considerations including coastal moisture, high winds, and seasonal rains that can accelerate wear on roofing materials. As a 3rd generation roofer, our founder Ken Cooper brings decades of firsthand knowledge that helps homeowners make informed decisions about whether repair or replacement is the right path forward.
Our Roofing Replacement Process
We follow a comprehensive, step-by-step process designed to minimize disruption while maximizing the quality and longevity of your new roof. Every project begins with a thorough inspection where we assess the condition of the existing roofing material, the underlying decking, ventilation systems, and flashing. We then provide a detailed estimate and walk you through material options so you can make the best decision for your home and budget.
Our replacement process includes the following key stages:
- Complete tear-off of existing roofing material down to the decking to identify any hidden damage or rot that must be addressed before the new roof is installed
- Inspection and repair of the roof deck including replacement of any compromised plywood or structural components to ensure a solid foundation
- Installation of underlayment and ice-and-water shield in critical areas such as valleys, eaves, and penetration points for maximum moisture protection
- Precise installation of new roofing materials following manufacturer specifications and local building codes to ensure warranty compliance and optimal performance
- Final cleanup and inspection including magnetic sweeps of the property to collect any stray nails and a walkthrough with the homeowner to ensure complete satisfaction
