Do Marin Microclimates Affect Your Roof?

The cities and neighborhoods of Marin County are each characterized by unique microclimates with a wide range of temperatures and atmospheric conditions that affect the life of your roof. From hot summers in Novato to the moist marine fog layer in Sausalito and Mill Valley, to Marin’s wettest spot – Kentfield each unique microclimate requires a roofing system with specific attributes that promote durability, high performance, and optimized energy efficiency.

Wet Winters

Marin County’s winters have a rich history of extremes. From drought years with as little as seven inches of annual rainfall to El Nino winters, characterized by a rapid succession of atmospheric river storms and unprecedented rainfall totals. When it doesn’t rain, roofs might be neglected, which can be catastrophic during a wet winter. The solution is to initiate a roof maintenance program to prepare your roof for the winter. 

Hot Summers

In the warmest areas of Marin, such as San Rafael, Lucas Valley, Nicasio, and Novato, the benefits of a cool roofing system are tremendous in lowering energy costs and keeping your home comfortable during the summer. 

Shady Cool Neighborhoods

Proper roof selection and an emphasis on maintenance are necessary for the shady neighborhoods of Marin, such as Mill Valley, Larkspur, and Fairfax, where roofs are vulnerable to the growth of lichen, mold, and moss under a canopy of redwood trees or oaks or from moist fog.

Bayside and Coastal

Reroofing homes on the shores of the San Francisco Bay, such as in Tiburon, Belvedere, or Sausalito, or coastal areas, such as Stinson Beach, requires specific considerations due to salt-water exposure and the possibility of corrosion.

Fire Harden Your Roof

It is important to note that many Marin homes and buildings are in designated “Wildlife Urban Interface” (WUI) areas. These neighborhoods are at increased risk of danger from major wildfires and are subject to more restrictive city and county regulations for roofing options. Throughout Marin County, building departments require a fire-retardant roof covering that is at least Class A in all WUI neighborhoods and other areas.

What is the true cost of a new roof?

As we reported previously, installing a new roof on your Marin County home is a good investment. Many home remodeling projects offer a poor return on investment at resale. Whereas the National Association of Realtors ranks new roofing as the top exterior remodeling project, with an incredible 105% return on investment.
