Hurricane Season Meets Its Match - Impact-Resistant Roofs

Synthetic shakeEvery June is the same: people think about graduation ceremonies, barbecues and summer vacation plans. Yet, as the weather turns warmer, it's also the month to think about preparing your home and family for potential problems.

Disaster Preparedness Month in June coincides with the start of hurricane season each year --- and for good reason. Hurricanes can impact millions of people living both on the coast and far, far inland. Flooding, extensive rain and very high winds are major concerns related to hurricanes. The National Hurricane Center encourages everyone to "Be Ready" and offers a checklist of information for your home and business.

Here's our question to you: Is your roof ready to handle potential severe weather?

Many roofing products simply don't hold up to severe winds and strong rain. But, products by DaVinci Roofscapes do. Our synthetic slate and composite shake roofing materials are built to weather the storm. They've even passed the strictest industry standards to earn a Class 4 impact rating. (See Polymer Roofing Welcomes Hurricane-Force Winds)

DaVinci shake roofing and slate roofing materials have a Class 4 impact rating which shows they are designed to resist damage from flying debris and hail. Check out this quick video to see how DaVinci products compare to other roofing materials ... and how they can help prepare your home against potential disasters!

From the Tech Team: Bellaforte Solid Shake Tile

Recently, a DaVinci contractor gave me a call to let me know that he loved installing DaVinci Bellaforté Shake. He said that the one suggestion he had, was that because of the very high profile of the DaVinci Bellaforté Shake, there were some situations where a solid tile would be helpful. One example of where a solid tile would be beneficial is in a situation where Bellaforté Shakes are installed in a closed valley in an area where there are a lot of messy trees, especially pine trees. In these instances, pine needles and leaves can catch on the ribs of the Bellaforté shakes where they are cut. While this doesn’t usually cause a performance issue it can sometimes detract from the overall look of the roof. Another example of where a solid tile can be helpful is in flashing situations where the cut edge of the tile may be exposed. While this is not a performance issue if it is in an area visible from the ground, it may not have the “finished look” that some customers would like.

 

I discussed this request with our design team and they worked quickly to develop a Bellaforté solid shake tile. These solid tiles can be used where tiles are cut around flashings, on flared rakes (gable ends), straight gable ends, and even valleys. It should be noted that these solid tiles are not the answer from an aesthetic point of view for a true open valley. The reason for this is when the solid tiles are cut for use in valleys, there is an occasional small void in instances where the tile cut crosses the gutter of the tile. These tiles also have occasional visible bubbles where the tile is cut, that may be objectionable to some customers. We recommend that when using Bellaforté Shake solid tiles the installer still use the closed valley or double w valley system.

Flying Garbage Cans? No Problem with a DaVinci Roof

Is there any chance we'll meet Tomas, Virginie and Walter this year? Those are the last three storm names that would be used for the 2016 Hurricane Season, which ends November 30.

Even though it's unlikely all the names on the hurricane list will be used this year, there is a very good chance that high winds and severe weather will continue to impact many areas of the United States. That's why high-wind resistant DaVinci Roofscapes composite roofing shingles are a good choice for homes all across the country.

Sustainable RoofCan you imagine the conditions your roof goes through at winds of 30, 50 or even 90 mph? A reporter with the Associated Press wanted to experience these conditions for himself, so he went to a wind tunnel laboratory at the University of Maryland. After getting harnessed in, he had the team crank up the winds ... all the way up to 100 mph.

Click HERE to see the video of how the winds impacted his body. Clearly, if he wasn't anchored and harnessed in, he would have been blown away. Now think about your roof.

During severe weather --- not even hurricane conditions --- high winds can rip some roofing tiles right off the roof. And, flying debris during a storm can deeply damage some roofs. Not DaVinci polymer roofing.

Our roofs are manufactured and tested to stand firm in extreme weather conditions. (see DaVinci Roof Tiles: Engineered to Withstand Hurricane Force Winds) DaVinci roofs meet the ASTME D3161 test for withstanding 110 mph sustained winds. Our simulated shake roofing and composite slate roof tiles also have a Class 4 impact rating (UL 2218 Impact test) ... so if a tree limb falls on your DaVinci roof or a flying garbage can hits it, you don't have to worry about broken tiles.

Understanding Class A Fire Ratings

Dry timber. Drought conditions. A lightning strike.  These three things can instantly spark a wildfire.

Summer is a time of tension for fire fighters throughout western regions of the U.S. and in many other states. During this time when conditions are right for the spread of sparks and flames to structures, homeowners are also on edge.

One way to gain some peace-of-mind is to invest in Class A Fired Rated composite roofing. This is the highest fire rating available for a roof, and one attained by DaVinci Roofscapes for all our products.

Want proof?

There are three tests our polymer roofs have undertaken to achieve the Class A Fire Rating. These include:

1. Intermittent Flame Test - an assembly of tiles is subjected to an intense flame for two minutes then turned off for two minutes. This is cycled 15 times to see if there is failure in the roof deck.

2. Spread of Flame Test -  flame and air current are applied for 10 consecutive minutes and then checked for failure. 

3. Burning Brand Test - in this test, a burning brand is placed on an assembly of roofing tiles with a high volume of wind behind it. The decking of the assembly is constantly monitored for 90 minutes to see if any fire burns through.  If fire burns through the roof deck anytime during the 90 minute trial, the tiles fail. 

Since seeing is believing, check out this video of flame spread testing of our DaVinci products:

DaVinci Roofscapes Introduces Four New EcoBlend Colors for Cool Roofs

We've done it again. DaVinci Roofscapes has launched four new EcoBlend options approved by the Cool Roof Rating Council (CRRC) to reflect sunlight and heat away from a home or commercial structure. The new color blends all meet Title 24 requirements for California. (See  What is EcoBlend?)

Newly-introduced color blends for EcoBlend polymer shake and slate roofs include: Tahoe-EcoBlend, Mountain-EcoBlend, Brownstone-EcoBlend, and Slate Gray-EcoBlend.

Cool Roof Colors

Cool Roof Colors

"California's newly-adopted 2016 Building Energy Standards (Title 24, Part 6) will require use of more energy-efficient roofing materials starting in 2017," says Ray Rosewall, CEO and president of DaVinci Roofscapes. "We've developed these new roofing color blends to meet, and in some cases exceed, these strict requirements.

"In recent years when wildfires and severe weather conditions have increased on the West Coast we've seen enhanced demand for our DaVinci fire- and impact-resistant synthetic shake and slate roofing products. The newly-introduced EcoBlend color family options allow homeowners and commercial property owners to use our durable roofing tiles while complying with the new Title 24 requirements."

EcoBlend color blends previously accessible from DaVinci Roofscapes and still available include: Weathered Gray-EcoBlend and Castle Gray-EcoBlend.

"While Title 24 is unique to California, structures in all areas of the country can benefit from incorporating EcoBlend roof tiles," says Rosewall. "Because these tiles reflect heat and sunlight away from a structure, they help reduce the cooling load, and as a result, increase energy efficiency of a building."

Sleep Secure with Composite Shake Shingles Overhead

"Burn, Baby Burn" is definitely NOT the theme song for the 2015 Fire Prevention Week. Instead, it's a very sensible message of "Hear the Beep Where You Sleep."

Fake Shake RoofWhile the National Fire Protection Association focuses primarily on fire safety within the home and the strategic placement of smoke detectors, it's important to also think about keep your home exterior safe from the spread of fire.

If you have real cedar roof shingles, you should be extra cautious. Wood shake roofs tend to have a faster flame spread than simulated shake roofing. The video showing fire testing of cedar shake roofing compared to composite shake roofing materials from DaVinci Roofscapes (click HERE to see video) shows that in less than 15 minutes, a real cedar shake roof can completely go up in smoke ... whereas a Class A Fire Rated DaVinci  fake cedar shake roof doesn't tolerate flame spread.

Here's the important message during Fire Prevention Week: composite shake roofing from DaVinci looks like natural cedar shake, but it has a Class A fire rating that proves it resists burning. That's especially important if you live in drought-stricken areas of the country where wildfires are prevalent.

2015 Hurricane Season: Are You Ready?

Severe Weather Preparedness

 

May 24 - 30 is National Hurricane Preparedness Week to focus us on preparing our homes and businesses for severe weather. Sponsored by the National Weather Service, you can get the details HERE about hurricane hazards such as storm surge, heavy rainfall, high winds, tornados and inland flooding.

If you live in an area prone to severe weather, you should consider an impact-resistant polymer slate or shake roof that has been tested to withstand strong winds. Composite roofing from DaVinci Roofscapes has been tested for wind and impact resistance and can be installed in high velocity hurricane zone areas.

Damage from airborne items (tree branches, yard items, etc.) during severe weather can be devastating. Having a roof that has achieved a Class 4 impact rating for the UL2218 tests reduces this risk. All of DaVinci's polymer roofing products have achieved a Class 4 rating, which is the highest grade possible. This means that DaVinci's composite roofing has a greater chance of helping protect your home from damage from flying debris during severe weather. 

DaVinci tiles have also achieved the Miami Dade County Acceptance and Texas Department of Insurance criteria for high velocity hurricane winds. The roofing tiles have the highest rating for straight line wind testing at 110mph in the ASTM D3161 test and have passed the TAS-125 certification test for wind uplift resistance in High Velocity Hurricane Zones.

As part of your personal preparations for Hurricane Season (which runs from June 1 - November 30), make sure to examine your roof to see if there are any missing shingles, curling or splitting shingles, lifting shingles or loss of granules. These shingles (or perhaps your whole roof if you find many of these damaged shingles) should be replaced immediately. Why? Because straight line winds and pressurized winds associated with hurricanes can uplift the shingles off the roof, causing massive damage.

Want peace of mind when hurricane-force winds start to blow? DaVinci polymer roof tiles are designed to help your roof survive severe weather. Applied properly by your roofing installer, our luxury roof tiles should provide added protection to your home when Mother Nature gets angry.

Help Deter Wildfire Spread with DaVinci Class A Fire Rated Polymer Roof Tiles

From coast-to-coast, the number "1" is very important when it comes to wildfires. All it takes is one lightning strike, one smoldering ember from a campfire, or one dropped cigarette to spark disastrous results --- especially in several drought-stricken states.

On July 1st, the National Interagency Fire Center issued their report that several key areas of the country will have above normal wildland fire potential through the summer months. Areas include portions of California, Nevada, Oregon, Washington and Idaho. And, there's potential for this "above normal" classification to expand to New England states in August.

Why are we sharing this scary weather prediction? Because DaVinci Roofscapes polymer roofing tiles are Class A fire rated with the proper underlayments. That's important to know --- especially if you install roofs in the geographic areas listed above.

As you might imagine, choosing "A" rated lightweight roofing systems is smarter to selecting a "B" or "C" rating on your roofing products. And, in some locations, an A rating is required by local codes.

Having attained a Class A fire rating means our composite shake and synthetic slate tiles have attained the best fire rating that is available in the market. It also means that our composite roofing products meet the following criteria:

  • Intermittent Flame - an assembly of tiles is subjected to an intense flame with a strong air current for two minutes then turned off for two minutes. This procedure is repeated 15 times. After the final flame cycle the air current is continued and the assembly observed for an additional hour to look for failure.

  • Spread of Flame -  flame and air current are applied for 10 consecutive minutes and then observed until the flame deck recedes. Once the flame deck recedes the assembly is checked for maximum spread of flame. 

  • Burning Brand - a burning brand is placed on an assembly of roofing tiles with a high volume of wind behind it. The decking of the assembly is constantly monitored for 90 minutes to see if any fire burns through.  If fire burns through the roof deck anytime during the 90 minute trial, the tiles fail.

Building Code Basics

The arrival of Hurricane Arthur on the East Coast over July 4th weekend shines the spotlight once again on building codes and the need for advanced polymer roofing products. As is the case in most situations, those coastal area properties constructed to meet the high standards of the Miami-Dade County codes fared better than those built to lower standards. Fortunately, more and more coastal areas are adopting those strict standards.

According to the Insurance Institute for Business and Home Safety (IBHS), building codes are needed to establish "predictable and consistent minimum standards that are applied to the quality and durability of construction materials."

At DaVinci Roofscapes, we take building codes seriously --- as should you. In general, codes are put in place and enforced to ensure the safety and health of building occupants. In the long run, stronger codes can be extremely cost-effective because of their enhanced safety and performance features.

Because we want our composite slate and synthetic shake roofing tiles to meet the strictest of building codes, we've made sure they pass the Miami-Dade County codes (click HERE).

Specifically, the DaVinci Slate roofing tiles we have created passed the Miami Dade County, Florida NOA No 06-308.03 test. These durable imitation slate roofs have also passed the following tests:

- passed the ASTM D 471 water absorption test

- passed the ASTM G21 Fungus (algae) test with no algae growth

- passed the ASTM D 638 tensile strength test with no meaningful reduction of strength on long-term weathering of material strength

 

If you're using our DaVinci Shake products, you'll find these cedar shake alternatives:

- are rated Class A for fire retardance in the Fire Test UL 790 with a VersaShield underlayment and Class C with an approved synthetic underlayment.

- passed Texas Department of Insurance (TDI) qualifications

- passed Miami Dade County, Florida NOA No 07-1203.03

Check Your Roof Before 2014 Hurricane Season Starts

If you live in a coastal area, the names Arthur, Bertha and Cristobal may make you shudder. That's because those are the designated names of the first three hurricanes in the 2014 Hurricane Season that starts on June 1.

This week (May 25 -31) is National Hurricane Preparedness Week and experts advise you to check on the condition of your roof now --- before hurricane season starts.

"Your roof should be checked annually to make sure it's holding up well after previous storms and to make sure it's able to handle upcoming severe weather conditions," says Mark Clement, co-host of MyFixitUpLife home improvement radio show and a professional contractor. “Repeated exposure to strong weather can take a toll on the home. Always review and evaluate the effectiveness of the entire home ‘envelope’ each year at the beginning of the hurricane season.

“Start at the top of your home and evaluate the condition of your roof, then work down to your windows, entry doors and garage doors. These are the four most critical areas of the home during hurricane season because if any one of these areas is compromised, then wind and pressure can enter the home with devastating results.”

The experts at DaVinci Roofscapes recommend checking to determine if there are missing shingles, curling or splitting shingles, lifting shingles or loss of granules on your roof. Both straight line winds and pressurized winds can cause different damage --- from uplifting the shingles off the roof to pushing intense wind-driven rain and flying debris onto the roof.

“Weather conditions have changed so much in recent years,” says Clement. “My recommendation is to always select an impact-resistant composite roof for the home. Even though we live inland in Pennsylvania, we put a DaVinci Roofscapes polymer slate roof on our house.

“This environmentally friendly roof has achieved Class 4 ratings for impact resistance along with the Miami Dade County Acceptance (High Velocity Hurricane Winds) and the Texas Department of Insurance, showing that the roofing tiles can withstand hurricane-force winds.

"In addition, DaVinci synthetic shake and imitation slate roofing tiles are rated Class A for fire retardance and have achieved the highest rating for straight line wind testing at 110 mph. The manufactured slate roof also has a limited 50-year warranty for added peace-of-mind.”

October 6-12 is Fire Prevention Week... What's On Your Roof?

If you've been watching all the wildfires that have occurred this summer, then it makes sense why a full week in October is devoted to fire prevention.

The truth is that every week should be fire prevention week.

As a manufacturer of roofing products, we are highly aware of the importance of fire prevention. After all, many roofs made of natural products like cedar shake shingles can be a catalyst to a much larger fire. It is for this reason that many communities around the country have outlawed the use of natural wood shakes on re-roofs. That's why products like DaVinci are so important - they allow for the aesthetic appeal of the natural roofing products that people have used for centuries, but add a performance aspect those natural counterparts never had. For example, we have made sure that all of our lightweight roofing tiles offer the best fire rating available for roofing products - Class A fire rating (ASTM E 108) when used with proper underlayments.

This video from our YouTube channel is probably appropriate for Fire Prevention wee. It shows our DaVinci Shake tiles vs. their natural counterpart during a Class A burning brand test. You will see how the DaVinci synthetic shake shingles stand up to fire compared to natural cedar shakes.


Having trouble watching this video? Click here to view.

 

Don't live in an area with wildfires? Fire prevention is still key because lightning strikes can start fires in an instant. On another note, you might also want to check with your home or building insurance company. They just might offer a discount for installing a Class A fire rated product.

Fire Codes and Your Roof: Class A vs. Class C Codes

Are you familiar with fire codes and how they work with roofs? Depending on where you live in the world, you may have more stringent fire codes than in other parts of the world. For example, in the United States, if you live in the Midwest where the rainfall is usually plentiful, the fire codes may not be as strict as they would be in New Mexico, for example, where wildfires can cause havoc on a number of properties.

Roofing tiles can earn one of three main ratings that range from "A" to "C". When a roofing product has a Class A fire rating, it has attained the best fire rating that is available. It also means that the material in question meets the following criteria:

  • Intermittent Flame - an assembly of tiles is subjected to an intense flame with a strong air current for two minutes then turned off for two minutes. This procedure is repeated 15 times. After the final flame cycle the air current is continued and the assembly observed for an additional hour to look for failure.

  • Spread of Flame -  flame and air current are applied for 10 consecutive minutes and then observed until the flame deck recedes. Once the flame deck recedes the assembly is checked for maximum spread of flame. 

  • Burning Brand - a burning brand is placed on an assembly of roofing tiles with a high volume of wind behind it. The decking of the assembly is constantly monitored for 90 minutes to see if any fire burns through.  If fire burns through the roof deck anytime during the 90 minute trial, the tiles fail.

A Class C fire rating on a roofing material, means the tests on the assemblies are done with 1 1/2" brands instead of 12" x 12" brands and the tests are run for shorter periods of time.

DaVinci Roofscapes tiles are Class A fire rated with the proper underlayments. The video below shows a burning brand test on our roof tiles.
