Q & A Guide to Snowguards

Does snow slide off of a DaVinci roof?
Snow tends to slide off all roofs, but is more likely to slide off metal, natural slate, glazed tile, and polymer tiles (like DaVinci roofs).  This is due to some of the same physical characteristics that help to make DaVinci such a long lasting beautiful roof.  DaVinci roofing products have smooth surfaces and don’t absorb water. This means that snow and ice have no place to “grip” as it might with some other roofing products. When snow begins to melt from a warm attic underneath, the snow blanket on top may slide off the roof all at once.

What is the solution?
Installing a pattern of snow guards or attaching snow fences near the eave can reduce or eliminate snow slides. Snow guards work by adding friction to the roof. Snow fences on the other hand, create  a barrier to prevent snow movement.  Snow guards are the preferred product for most areas while snow fences are used in very high snow areas like ski resorts.


Who should consider snow guards?
Snow guards should be considered in parts of the country where accumulating snowfalls occur. Many roofs or parts of roofs may not need any snow guards at all. In fact, some structures are designed so that snow will slide off of the roof, reducing the stress on the structure.  

Does my house need snow retention?  
It all depends on what the snow may fall on as it slides off of the roof. The installation of snow guards should be considered on roof areas where sliding snow might land on people or property. Decks, walkways and driveways are obvious examples of such areas.  
 
What snow guards should I use?
There are many different types of snow guards. Snow guards for use on DaVinci roofs must have an attachment strap and be manufactured of long lasting- non-corrosive metals. The best types to use with DaVinci products are manufactured of copper, stainless steel or coated aluminum. Plastic snow guards, typically used on metal roofs, are not recommended for DaVinci roofs.  
 
What if my roof is already installed without snow guards?
The best time to install snow guards is when your DaVinci roof is being installed. But if your DaVinci roof is already installed, don’t worry. There are snow guards available that are specifically designed to be installed after your roof is on.  These are known as retro-fit snow guards and this type of snow guard won’t compromise the integrity, warranty or longevity of your beautiful DaVinci roof.
 
Ask your contractor if you need snow guards.  The final decision on whether or not to install snow guards rests with you and your contractor.

**Snow guards should be considered in all geographic areas where accumulating snow fall is possible.**

Do Extreme Freeze-Thaw Cycles Affect DaVinci Roof Tiles?

In some parts of the country roofing materials experience very harsh weather with extreme temperature change. The high country in the Rockies or Sierras is very indicative of this. In these mountain areas daily temperature swings of 30 to 40 degrees are common and 50 degrees or more are not unheard of. The ambient temperature can be 75 degrees wPolymer Roofith a roof temperature of 120 degrees or more during the day and then the temperature can fall considerably below freezing overnight. This change in temperature, especially if moisture is added to the mix, can be very troublesome. If a roof covering absorbs moisture and goes through-freeze thaw cycles there can be  damage that results in crazing, cracking, splitting, etc. Over time these freeze-thaw cycles can destroy a roofing product.

At DaVinci Roofscapes we have designed our tiles to be impervious to freeze-thaw. DaVinci tiles don’t absorb water so there are no issues with the tremendous force of freezing water. In addition, DaVinci tiles are very thermally stable, in fact the coefficient of thermal expansion is 10-3in/in °F. What this means is that the DaVinci 12” slate tiles expands 1/12” with a 100 degree temperature swing. Because of this you don’t get the buckling or movement that puts strain on fasteners as some products do.

DaVinci Roofscapes is a very popular roofing product for the resort areas of the Rockies and Sierras for a reason; it works. Well, also because it looks great!

Figuring Waste for DaVinci Polymer Roofing Tiles

Deciding how much waste should be figured for the different DaVinci roofing products requires the contractor to answer a few questions.Polymer Roof Tiles

  1. Can the installers be counted on to be careful and save material where they can?

  2. If they cut a tile for a valley will they use the remnant on the corresponding hip?

  3. On Multi-width installation will they measure for the correct tile on the gable end or will they cut the tile and throw away the rest as waste?

  4. On Single-Width will they use the cutoff portion from the right side of a gable and use it on the left?

  5.  

If the answer to all of these questions is yes then DaVinci Multi-Width Slate and Shake can be installed with < 1% waste; unless there are valleys in the roof which don’t have corresponding hips. In that case there is 1 square of waste for every 100 linear feet of valley (that counts both sides of the valley). Single-Width Slate and Shake can be installed with < 2% waste with the same stipulation as above.

Bellaforté Slate and Shake will have more waste than our other products because often times the remnant of a cut cannot be reused. A good rule of thumb for the Bellaforté products is 4% waste with a conservative installer but that can go up to 8% if the installers are not conscientious about saving material.

Using The Right Color Chalk Line Makes a Difference

Over the years I have seen many steep slope roofing installations where the installer used red or black chalk when snapping chalk lines. On many surfaces those lines are virtually permanent and will last for years. When it says "permanent chalk" on the bottle you should believe it. I was recently on a DaVinci Roofscapes composite slate roof installation where the installer used red chalk to achieve a staggered pattern. I took the photo below after an attempt was made to power wash the tiles with the red lines with no luck.

Polymer Slate


A better method to use when installing DaVinci tiles in a staggered application is to snap lines on the underlayment and the lay the tips of the tiles to those lines as illustrated below.

Slate Roof Installation


In all roof applications regardless of where you are placing your lines, blue chalk is a better choice than red or black. Even though blue chalk can sometimes be hard to get off as well, if and installer drops a red chalk box and red chalk falls out you can have a major disaster on your hands.

Helpful Tip: Installing DaVinci Tiles with No Waste

I often get calls from contractors about how much waste they should add to their bid when figuring multi-width DaVinci Slate or DaVinci Simulated Shake roofing products. Although I don't know how often I'm believed, my answer is "there is no waste on a hip roof and one square for every 100 lineal feet of valley on a gable roof". Installing DaVinci tiles with no waste is a huge competitive advantage when compared with other steep slope systems where 10% or more waste factor is common. 

I have already discussed how to use a combination of our plastic slate tiles to avoid waste on gable ends in a previous tip. Another way to avoid waste is when cutting tiles for valleys. When I cut tiles for valleys I find the correct angle and cut all my tiles with a circular saw. 

valley

 

I then use all the valley cuts shown on the right in my valleys and then the cuts  that are leftover are the perfect angle to use to finish the hips. Not only does this save material but it also saves time.

Class A Fire Rated Roof Tiles... What Does that Mean?

shake brandWhat does a class A fire rating mean on a roofing product mean? It means that the roof covering has undergone extensive fire testing using the ASTM E 108 test standard at the Class A level. Class A is the best classification available.

For polymer roof coverings there are three tests.

1. Intermittent Flame - 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 -  flame and air current are applied for 10 consecutive minutes and then checked for failure. 

3. Burning Brand - This is my personal favorite...not that I liked starting fires as a child. 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. Below are pictures of DaVinci's Class A Fire rated slate and simulated shake roofing. DaVinci tiles PASS these tests with flying colors.

Roofing 101 for Homeowners

Here's a fact of life: as a homeowner, sometimes you forget about your roof overhead. Unless you have a gaping hole, storm damage or messy leaks, it's easy to take your roof for granted.

Fortunately, your roof doesn't forget about you. It usually protects your home and its contents for many years before needing to be replaced. But how do you know when it's time to replace your roof? Start first by determining the age of your roof. Every product in your home has a life cycle ... and usually 20 to 25 years is about the length of time you can get out of an asphalt shingle roof.

Next, think about your geographic location. Does your roof get subjected to searing sun, heavy snows or hail? If so, that may shorten the roof's lifespan.

To get a good idea of how your roof is holding up, climb a ladder and look around ... or, go to a high spot in the area and look at your roof through a set of binoculars. If you see curling, splitting or missing shingles, that's a clear sign there's damage to your roof that needs to be addressed. Don't be afraid to call in a roofing expert to do a professional evaluation of your roof. Getting the insights of someone who deals with roofs for a living can be a valuable asset.

Need some good, practical reasons to invest in a new roof even if there's no apparent damage? Consider this ... by adding a new roof you can increase the resale value of your entire home. Or, if your area has seen changing weather conditions in recent years, it's a good idea to invest in a strong, low-maintenance polymer roof with a 50-year roof warranty.

When it's time to replace your roof, look no further than DaVinci. Our synthetic roofing tiles are made with state-of-the-art UV stabilizers embedded throughout the polymer to create a durable synthetic roofing tile which resists mold, algae, fungus and insects, with virtually no curling, or cracking so they’re headache-free. And, all DaVinci imitation slate and shake roof tiles have a Class A fire rating available, are Class 4 rated for impact resistance, and have passed wind tests at over 110 MPH. Just imagine having beautiful, virtually maintenance-free polymer roofing slate or shake synthetic roof that adds value to your home while protecting it from severe weather conditions!

Five Top DaVinci Install Tips

Looking for some great tips for installing DaVinci polymer roofing tiles? People always ask me for tried-and-true hints for better installation. So, here are a few key points to keep in mind:

#1 - Install snowguards during the roof installation rather than retrofitting them later. It's easier to get snowguards in place when the DaVinci roof  tiles are initially installed than going back in a year or two and fitting them in place.

#2 - Be careful with your chalk lines. Blue chalk is probably the better choice over red or black (red chalk will almost certainly permanently stain our tiles). When it says "permanent chalk" on the bottle, you should believe it. And the big hint when installing DaVinci composite roofing tiles in a staggered application is to snap lines on the underlayment and then lay the tips of the tiles to those lines rather than marking the synthetic roofing materials.

#3 - Try using a rake tile on gable ends when installing the Bellaforté Shake products. It makes these luxury roof tiles easier to install because you don't need to be too concerned with how precise your cuts are on the gable end --- the rake tile covers up all the cuts. And, if you install the rake tile with the optional screw in the butt of the tile (on the fascia side) you will definitely enhance wind performance.

#4 - Avoid wasteful tile cuts for valleys by finding the correct angle and then cutting your polymer tiles with a circular saw. Then use all the accurate valley cuts and use the leftovers to finish the hips.

#5 - Nail DaVinci steep slope roofing tiles with copper, stainless steel, or hot-dipped galvanized nails during installation. The reason for this recommendation is that we expect our synthetic roofing tiles to last for a very long time (yes, a 50-year roof is what we hope every project achieves!) and we don’t want the fasteners to rust, become ineffective, and be the mode of failure of the Class A Fired Rated roofing system.

DaVinci Solid Accessory Tiles

If you're a roofing installer looking to finish a course, rake end or valley with a solid piece of synthetic slate or shake, DaVinci has the solution. Solid polymer DaVinci slate and shake accessory tiles are available in the company's Multi-Width and Valoré product lines.

The unique design of DaVinci composite slate and imitation shake tiles has a rib structure to provide improved rigidity, reduced weight and allows DaVinci to create a thick profile that is lightweight.

“While a solid accessory tile is not required for a successful roof application, we recognize that some installers prefer to use it as an option," says Ray Rosewall, CEO and president of DaVinci Roofscapes. "The solid tile is just another method of blending the appearance of cut tiles to give a polished look to a finished project.”

Available in just the right color to match the color blend you have chosen for your roof, the solid slate synthetic accessory tiles are 18-inches long and 12-inches wide and solid shake accessory tiles are 22-inches long and 12-inches wide.

Mini-History Of Synthetic Slate

Many people think that synthetic slate and shake roofing materials are a new idea. That couldn’t be further from the truth. In fact synthetic slate tiles were manufactured in Europe in the mid-1800s and manufactured in the US at the beginning of the twentieth century. The tiles were very long- lasting, weren’t affected by heat or moisture, and were fire-proof. These tiles were installed on roofs throughout the US and performed well for many years. There was one problem though; the tiles were about 75% Portland cement and 25% asbestos. And as we all know we started figuring out in the 1970s and early 1980s that asbestos was not the best thing for our lungs.

Once the manufacturers of synthetic slate and shake found they could no longer use asbestos they had to make a quick change to a different kind of filler. Most companies chose an organic (cellulose) fiber. This new formulation for tiles that used cellulose instead of asbestos generally didn’t work very well. There were many issues including, crazing, cracking, delamination, and deterioration.There are some parts of the country where these problems gave synthetic slate and shake a very bad name.

When we started work developing the formula and process for DaVinci tiles in the mid 1990s we had the advantage of being able to reference the success and failures of past roofing products. That knowledge along with new technologies allowed us to create the highly engineered polymer system and the unique injection molding color system we use today. This engineered polymer system is an ideal material for a roof covering and allows DaVinci to be installed in all geographic areas and climates. There are DaVinci roofs in all 50 US States and internationally from the cold climates of Canada to the warmth of Bali, Indonesia.

New Bellaforté Shake Hip and Ridge Idea

When I was traveling in Colorado a couple of weeks ago I saw a fabulous looking Bellaforté Shake job being installed by Turner Morris Roofing Systems. Turner Morris is a high-end contractor located in Arvada, Colorado. Actually it was multiple jobs that I saw as they were installing hundreds of squares of Bellaforté Shake on a series of Townhouses. When Scott Cunningham of Turner Morris showed me around the jobsite I saw that the roofs looked great. They had some nice flashing details for installing snow fences, in fact all the metal details I could see were very professionally done. The one detail that really stood out to me was the way they started the hip and ridge.

In our installation instructions we describe cutting a piece of hip and ridge in triangles and mitering them on the bottom to start the hip and ridge. I guess Scott’s team didn’t like that idea, and as shown below used painted steel broken just right so that it very nice and neat. The metal blends in well and makes for a very nice look. 

If any of you have novel installation details you would like to share, don't be bashful, please let us know!

Retrofitting Snowguards

I've had several requests to give recommendations for retrofitting snowguards on DaVinci Roofscapes steep slope roofing products. The first recommendation is to install them when the roof is being installed. It is much easier that way. If the DaVinci lightweight tiles have already been installed however, and you find that snowguards are needed, there is a simple solution to the problem. 

snowguardsAccording to Lars Walberg president of Rocky Mountain Snowguards, "For a retrofit application you need to apply sealant to the top of the DaVinci shingle where the snowguard will be placed.  The snowguard is placed in the recommended pattern such that 2" of strap is showing between the face of the snowguard and the butt end of the shingle above. Then (2) 2.5" self tapping fasteners with gaskets are driven through the snowguard strap approximately 1/2" below the butt end of the shingle above, through the shingle and substrate until tight."

Walberg goes on to say that, "The appropriate snowguard to use in this application is the ST9 by SnowTrapper available in copper or dark bronze coated aluminum".

There are certainly other snowguards by other manufacturers that would also work well with our synthetic slate and simulated shake roofing. We don't recommend or endorse products that we don't manufacture but we do support his installation method.

Little Bump... Bigger Problem

DaVinci Roofscapes steep slope roofing tiles are designed with an engineered rib structure to make them strong, and assure that they stay flat. This rib structure does a very good job keeping the DaVinci composite shake and slate tiles flat. In fact the rib structure prevents the tiles from curling down to follow the contours and bumps on uneven roof deck. This is why it is always important to make sure the deck is flat and clean. A small bump in the decking can cause the butt of the tiles to rise farther than the original bump. In the following picture you can see that a 1/8" shim can cause the butt of the tile to rise 1/4" or more.

Custom Installations

DaVinci Roofscapes prides itself in being the best choice to truly create a custom roof. DaVinci offers 49 in-stock colors that can be blended to your specification. We can also create tiles from custom colors that are only limited by your imagination.

All of these colors and how they are blended is only part of the customization process. The way the tiles are installed is another way to make your roof truly unique. The tiles can be installed with a very unusual stagger or can be doubled or tripled up to make interesting textures. Tiles can also be curved, bent, cut, etc. to accommodate most any structure.

A good example of a custom staggered installation is this European Blend in DaVinci Slate by Rodney Turner.

 

An example of adding extra tiles in places to add texture is this roof installed in Colorado in a custom weathered green color.

 .

 

DaVinci Shakes are cut and molded to accommodate the fantastic structure below in Upstate New York.
