Top Ren Reasons to Install a Metal Roof – Even in Florida

metal roof melanie miamiA metal roof in South Florida may seem counter-intuitive. Under our summer sun, metal gets hot enough to cook an egg, right? But a metal roof actually reflects over 65% of the solar rays compared to only about 25% for asphalt shingle. And coated metal roofing also has a high degree of “thermal emittance,” which in plain English means they cool off fast. So here are the first of my top ten reasons to consider a metal roof in South Florida:

1. SAVE MONEY ON YOUR UTILITY BILLS: An Oak Ridge National Laboratory study reports that a metal roof can save homeowners up to 40 percent in summer cooling costs. EnergyStar.gov estimates that an ENERGY STAR rated metal roof can reduce peak cooling demand by 10-15 percent.

2. REBATES AND TAX CREDITS: Through the end of 2011, installing a metal roof qualifies for a 10% credit (up to $500) on the cost of the roofing materials. FPL offers a $0.45 per square foot rebate for qualifying metal roofs.

3. DURABILITY: Metal roofs can last well over 50 if properly maintained, and most manufacturers provide transferable warranties of at least 20 years. Metal roofing is resistant to fire, mildew, insects and rot.

4. SAFETY: Most metal roofs are rated to withstand hurricane winds of 110 mph to 130 mph winds – an important consideration in South Florida. Metal roofs are also fire and hail resistant, and many manufactures include fire, hail and wind protection guaranties.

5. REDUCE YOUR INSURANCE PREMIUMS: Homeowner’s insurance companies in at least 20 states (including Florida) provide wind, fire &/or impact discounts ranging from 18% to 35% off annual premiums.

6. ENVIRONMENTALLY FRIENDLY: Most metal roofing manufacturers use a minimum of 25% recycled content, and 98% of the finished product is recyclable. Asphalt shingles, by contrast, often contain asbestos which prohibits recycling under federal law. For new construction, a metal roof qualifies for credit towards LEED certification.

7. LIGHT WEIGHT: Metal roofing weighs as much as 75% less than slate, clay or concrete roofing, and approximately one-third less than asphalt shingle. This means homeowners will not be faced with additional structural requirements as can happen when switching to tile roofs; and your contractor may even recommend downsizing existing roof support.

8. BETTER INSTALLATION PROCESS: Metal roofs can be installed quicker than most other roofing systems, and can even be installed directly over the old asphalt roof. A metal roof is ideal for the minimally pitched roofs found on the MiMo style homes found in South Florida.

9. VARIETY OF COLORS AND STYLES: In addition to the classic standing seam style, metal roofs are now manufactured to look like regular shingles, barrel tile or even cedar shake. (See the photo above) So whatever style your home is, you can find a metal roofing style to compliment it.

10. INCREASE YOUR HOME’S RE-SALE VALUE: According to the 2005 “Residential Cost Handbook,” the appraised value of a home increases by $1.35 per square foot when a metal roof is installed. “Remodeling Magazine” reports that homes renovated with metal roofing gain between 1% to 6% in resale value over homes with asphalt roofing. It makes sense considering the long term transferable warranties, long life of the roofing system, lower maintenance costs and the substantial energy savings. A quality metal roof brings added beauty and value to your home that you and your future buyer will enjoy!

The Green Giant – Can a 10,000 Square Foot Home Be “Green”?

Alton Road, Miami Beach, FL - LEED Platinum
2020 Alton Road, Miami Beach – LEED Platinum

There is a green controversy brewing in Berkeley, California. Mitch Kapor, founder of Lotus Development Corp and an international philanthropist, wants  to build a 10,000-square-foot house complete with a 10-car garage. Under Berkeley’s current green point system the house would qualify for Berkeley’s “green” designation despite its size, and that has neighbors and local environmentalists upset.

According to the New York Times: Berkeley’s green point system was developed by a nonprofit group called Built It Green and adopted by the city government. Items on the checklist include: tightly seal the air barrier between the garage and living area; insulate hot water pipes; use Forest Stewardship Council-certified wood; use paint low in volatile organic compounds. About 70 local governments in California have ordinances based on the Build It Green checklist, according to Bruce Mast, an executive of the organization.
The article also correctly notes that the United States Green Building Council’s LEED program does reduce points for larger than average homes. Those points must then be regained with additional “green” features and building practices in order to achieve a LEED designation.

While virtually everyone agrees that smaller footprint homes are better for our environment, not everyone is going to give up their large luxury homes – nor do I think they should have to. Those who can afford to build a luxury home are also the people who can best afford to include cutting edge “green” materials and techniques, which will in turn benefit all green building at all price levels. We should continue to encourage this type of “green” investment with a sensible point system like the LEED program that addresses the size of the home as well as the sustainability of its design.

Neighbors Susan and Chuck Fadley were quoted in the article as saying that “green building begins with using ‘just enough’ and preserving what already exists. Clearly the idea of ‘just enough’ is not part of the design concept.”  And as an ideal, I agree. But in our idealism, we must not make this or any aspect of sustainable living seem so austere that its achievement feels like a punishment. A luxury home that is also a genuinely “green” home should be showcased because it allows the general public to see that “green building” doesn’t just mean living in a yurt anymore.

The Art of Sustainable Luxury

“The Art of Sustainable Luxury” was how the event was billed and on March 25th I was privileged to tour the first LEED for Homes Silver Certified Luxury Residence in Miami-Dade County. What this magnificent 5200 square foot waterfront home shows is that luxury does not need to be sacrificed to low-impact sustainable living.

LEED Silver Home 400x300When the owners first discovered the land parcel for their future home many years ago, the LEED (Leadership in Energy and Environmental Design Green Building Rating System) for Homes was still being developed. But by the time they acquired the property, the owners knew they wanted to integrate energy efficiency and environmentally sound elements into their home’s striking design. To help them achieve their goal, they partnered with KZ Architecture; Bell-Aqui, Inc landscape architects; Arbab Engineering, Inc; LNI Engineering; Gary G. Bloom PE civil engineer; and Alejandro Vargas at Visual Lighting. And to supervise the various certifications, the team brought in Gary Shlifer of Green Building Florida; Banks Clark of Environment, Safety and Health LC; and Eric Martin of Florida Solar Energy Center.

In addition to creating a home of breath-taking beauty, the team achieved an impressive set of green certifications:

• LEED for Homes Silver with 78 points
• FGBC Green Home Standard Gold 184 Points
• Energy Star for Homes HERS 72
• Florida Yards & Neighborhoods 226 Points

One of my favorite features of the home is the rainwater harvesting system with a 2500 gallon cistern located under the house and 83% of the roof area dedicated to rainwater capture. The system provides approximately 80% of their annual irrigation needs. Ninety two percent of the home’s finishes (paints, adhesives, etc) were no VOC (Volatile organic compounds) and the home was built with a wood-free insect resistant structure. In Florida, with our termites, carpenter ants and humidity, wood-free construction seems like such an obvious choice, doesn’t it?

The list of sustainable elements incorporated into this home was several pages long and included everything from dual-flush toilets to an exterior ceramic coating that insulates the home the way ceramic tiles insulates the space shuttle for re-entry. With all of the amazing attention to detail, the homeowners will realize almost 30% improved energy efficiency over similar new construction homes built to Florida Code in the same time period. In addition, they diverted 88% of the construction waste away from our landfills. Without a doubt, this home provides a model for what other luxury home developers and owners can accomplish.
