Considerations for Roofing System Design

OAKLAND — Planning to replace your roof? If so, you’ll want to make sure your new roof meets your specific needs and preferences. Here are a few considerations to make when designing a roofing system:

Long-term plans

How long do you envision yourself living in the home? If you plan on moving in five years, a practical, mid-range roofing system will likely make more sense than a high-end, cosmetically appealing one.

Aesthetics

Do you have specific ideas about the visual look of your roof? In this case, your roofing contractor can tailor your roofing system to include aesthetic features like copper flashings and designer shingles.

Fire risk concerns

Wildfires have become a major concern in the Bay Area during the last several years. Read more

Achieving Title 24 Compliance With Your Roof

OAKLAND — California’s Title 24 energy code now extends to residential roofing, with specific requirements for both flat and sloped roofs. For this reason, if you’re planning to replace your roof in the near future, you’ll need to ensure it meets these requirements.

Fortunately, there are many options for achieving Title 24 compliance with a roof. One is to use cool roofing materials, which are specifically designed to improve energy-efficient performance. For sloped roofs, these include cool roof shingles, synthetic shakes and slates; for flat roofs, these include cool roof coatings, as well as PVC and TPO style roofs.

If you’re partial to a particular roofing material that’s not Title 24-compliant, Read more

Fire-Safe 2020: Defending Your Home Against Wildfires

Posted on June 30, 2020 by James Florence

After being hit particularly hard during the COVID-19 pandemic, California seems due for a summer reprieve. Unfortunately, this is unlikely to be the case. Not only are many areas of the state seeing a resurgence of novel Coronavirus cases, we now face another, more familiar yet equally concerning issue: wildfire season. Each summer, wildfires destroy thousands of acres and homes throughout California, and this year looks to be no exception. That’s why residents (particularly those situated in the wildland-urban interface) must be vigilant about maintaining fire-safe conditions on their properties. Consider the following advice for defending your home against wildfires. Read more

Benefits of Hiring a Professional Window Washer

Posted on June 23, 2020 by James Florence

Now that Bay Area counties are finally reopening, many residents are playing catch-up with maintenance tasks that normally would’ve been completed earlier in the season. For example, your home’s windows may still be caked with residue from the rainy season. Before you reach for that bottle of glass cleaner, consider a better option: hiring a professional window washer. Here are a few reasons you should leave your panes to the pros. Read more

Thinking for Reopening and Beyond

Posted on June 04, 2020 by Jim Stein

What’s going to happen after our local economy mostly reopens? Everybody has a prediction, but nobody knows for sure. We can only guess how things will play out during the rest of this year and the next. Your guesses are actually valuable. Organize them to help you think through high, medium and low future scenarios. Then, create strategies for each scenario so you’re well prepared for an uncertain future. Here’s how to do it.

Think in three time periods—we’ll use Red Phase for the time we’re in Shelter-in-Place (SIP), Yellow Phase for an Assessment period and Green Phase for the New Future. Think about each of these time periods and plan your company’s actions based on an Optimistic, Read more
