New Roof Installation in Marin County and the greater North Bay Area
A new roof is one of the most significant investments you can make in your property. Whether you own a home or a commercial building, the roof is your first line of defense against the elements, and getting the installation right from the start makes all the difference in long-term performance and value. At Ken Cooper Roofing, we bring decades of hands-on expertise to every new roof installation project. As a family owned and operated business since 1973 and a third generation roofer, our commitment to quality workmanship, honesty, and reliability means your project is handled with the care and precision it deserves.
The roofing industry has evolved dramatically over the past several decades, with advances in materials, underlayment technology, and ventilation systems that significantly extend the lifespan of a new roof. According to industry data, a properly installed asphalt shingle roof can last between 25 and 50 years depending on the materials selected, while other roofing systems such as tile, metal, or composite materials can perform even longer. We stay current with these advancements and hold GAF Master Elite Certified status, a distinction held by only a small percentage of roofing contractors nationwide. This certification reflects our proven track record of professional installation practices, proper licensing, and ongoing training.
Our New Roof Installation Process
Every successful new roof installation begins with a thorough assessment. We start by evaluating the existing structure, checking the roof deck for integrity, inspecting ventilation pathways, and identifying any underlying issues that need to be addressed before new materials go on. This initial evaluation is critical because installing a new roof over compromised decking or poor ventilation can lead to premature failure and costly repairs down the road. Our founder Ken Cooper built this business on attention to detail, and that philosophy is embedded in every step of our process.
Once we complete the assessment, we work closely with you to select the right roofing system for your property, climate conditions, and budget. We want you to be as informed as possible when making your roofing decisions. Our process follows a carefully sequenced methodology to ensure lasting results:
- Complete removal of existing roofing materials down to the roof deck to expose any hidden damage or deterioration
- Deck inspection and repair including replacement of any rotted or weakened plywood or sheathing
- Installation of underlayment and ice and water shield in valleys and vulnerable areas to provide secondary moisture protection
- Precise installation of the selected roofing material following manufacturer specifications and local building codes
- Flashing installation at all penetrations including vents, chimneys, skylights, and wall transitions
- Final inspection and thorough cleanup of the entire property to ensure no debris or fasteners are left behind
Roofing Materials We Install
Choosing the right material for your new roof depends on several factors including the architectural style of your building, local weather patterns, energy efficiency goals, and long-term maintenance preferences.

- Composition roofing providing excellent durability and fire resistance while complementing various home designs
- Flat and low-slope roofing systems ideal for commercial buildings and modern residential designs requiring specialized membrane or built-up applications
- Tile and specialty materials for properties that demand a distinctive aesthetic with long-lasting performance
Why Proper Installation Matters
Industry studies consistently show that the majority of premature roof failures are caused not by material defects but by improper installation. Ventilation that does not meet building code requirements can cause heat and moisture buildup in the attic space, leading to warped decking, mold growth, and drastically shortened shingle life. Improperly installed flashing is another leading cause of leaks that may not become apparent until significant water damage has already occurred inside the structure.
At Ken Cooper Roofing, we eliminate these risks by following rigorous installation standards on every project. Our personable and friendly staff reduces the natural anxiety you might experience when tackling such a large reconstruction project. We keep you informed at every stage, provide honest answers to all your questions, and ensure the job is done right the first time.
