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.


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.

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

What a Surprise!

Posted on October 14, 2019 by Greg Louie

Recently, my family and I went to a restaurant and there was a short wait for a table. While we were waiting, the host offered us and a few other patrons some complimentary coffee or water. As someone who pays very close attention to customer service, I observed what kind of responses the offer received. Everyone seemed very appreciative and it was clear that this little touch had made a big impression.

The drinks came out immediately and made the wait go by much quicker. In fact, this simple gesture prompted many of us to start talking to each other. It began with general pleasantries (“That’s so nice!”) and turned into further conversation (“Have you eaten here before? Read more
