Modern Vent Pipe And Chimney Stack Protection

vs ad

One of our most common complaints from customer is the damage caused by sliding ice and snow that bends and breaks their ventilation pipes. They typically have little protection from being crushed or sheared during an ice and snow slide. Pipe boots are often damaged, leading to roof leaks and costly repair bills.

There are several ways to protect vent-pipes, chimney pipes, and masts from unnecessary damage. We typically recommend installing snow guards in addition to vent protection as a means of damage prevention.

Most snow guards are designed to hold ice and snow in place until it can safely melt off. They are properly installed when installed in multiple rows, spaced evenly up the slope. In the event that a full snow guard system is not required for a particular project, a pointed cutting guard can be used just above the vent-pipes to reduce the chances of damage. This type of installation is commonly referred to as “Isolated Placement” and is not recommended for use with flat faced snow guards. The strategy of an isolated pattern, using a pointed snow guard system, is to spread the pattern in an arrow shape to break ice and snow into smaller pieces helping minimize vent pipe damage. The Snowbreaker from IceBlox, Inc. is a good example of this type of cutting guard. It can be installed 3 ways; glue, mechanical fasteners, or peel and stick.

Some customers choose to install devices known as crickets or saddles. These products are used to divert ice and snow around the upper side of a chimney or vent pipe. Crickets are typically made from metal and may even be covered in the same materials as the roof.

A newer method for combating this problem comes in the form of the VentSaver product by IceBlox, Inc. Ventsaver is available in three different sizes to accommodate different pipe sizes. These devices, often referred to as “cricket eliminators”, help prevent crushed vent-pipes by splitting and diverting the snow while also adding support to the vent-pipes, chimneys or masts. The fin design cuts through packed ice and snow, causing the snow slide to divert around the pipe, and to assist in shedding the ice and snow from the roof. Up until quite recently, these products were only for use with exposed fastener roofing. Now an adapter plate is also available for mounting on most standing seam roofs.

Between late spring and early fall is the best time to plan and install snow retention systems while the weather is good and the roofs are clear. Installation options start to become limited once the temperatures drop and the snow starts falling. Call for more information.

Color Matching Snow Guards– What If My Roof Isn’t New?


Many of our customers have the luxury of owning brand new metal roofs. With the hundreds of available roofing manufacturers today, color options are nearly endless. Home and building owners now have more freedom of expression than ever before.  When it comes to matching colors for our Stainless Steel Snow Guards and our Snobar/Colorbar systems, a new roof is ideal. We have access to hundreds of colors, covering the broad spectrum of shades and hues available in today’s roofing market. Most of the time, simply knowing the manufacturer of your new roof is enough information for us to determine a proper match for your snow guard system. Correct matching, in these instances, can be achieved simply by looking at the manufacturer’s color chart and finding a corresponding powder.

There are other times, however, when a customer may decide to install guards on an older roof. If your roof has become faded or discolored, do not lose hope. There are a couple of options that will allow you to ensure the best possible color match for your roof. When dealing with customers with older roofs, we require a physical sample to be mailed to our headquarters in Lemoyne, Pennsylvania. Once the sample arrives, we can match it against our color selection. The best samples are those that are small pieces of the existing roof. Many times these small samples are taken from areas of the roof that are not visually obvious. Other customers will choose to remove a color-matched fastener from the roof and send that in. If neither of these options seems like the right choice for you, there is still one more type of sample that you could provide. A paint swatch from your local hardware store could be the perfect solution for this problem! Paint swatches are free and readily available to anyone! Simply select a couple of cards that closely resemble your roof, then send us the closest match and we will get to work.

We, unfortunately, cannot match your color based on a photograph. Printed photos rely on ink that may not produce an exact match to your roof. This, paired with different camera settings used to take the photos can cause quite a headache for our specialists. Digital photos, provided via email, are also not accepted. No two monitors have the same color settings. Colors can change dramatically when translated digitally. For these reasons, a physical sample is always your best bet.

When choosing snow guards for your roof, custom colors can add an extra bit of style to your roof. We are here to make sure that you get exactly what you are looking for. Don’t let your investment become an eye sore. Contact us today and don’t forget….it’s never too late to teach an old roof new tricks.

Snojax I – The Guard That Started It All!


For over 35 years, we have been bringing you the best in polycarbonate snow guards for your roof. However, the Snojax I is the one that started it all! This cornerstone of the non-metallic snow guard industry was invented by Jack McMullen in 1976.

Jack had been a metal building dealer for the construction industry for many years. He had seen the materials and methods that homeowners and contractors were using to retain snow. At the time, people in snow areas fought rooftop avalanches by attaching small upright strips of wood or metal across the lower part of their roofs. While these attachments often worked, they led to other troubles for home and building owners alike. Wood would soften and rot while inexpensive cast metal guards would often lead to ugly stains on rooftops. Jack began researching better materials to improve snow guard performance and reliability. Polycarbonate had just recently become available, a clear, UV stabilized thermoplastic resin that has high impact strength and excellent resistance to extreme heat and cold. After testing and prototyping with this new material, the Snojax I was born.

The Snojax I is the “original” clear snow guard designed to be mechanically fastened through the roof panel into a structural purlin or support below. Because of the unique straddling design, they fit most brands of mechanically fastened 36” panels with three 12” flats of four 9” flats. Molded mounting holes are provided in the base of this guard for mechanical fastening and eliminate the need for pre-drilling when used with a self-tapping #14 screw. Because of the narrow design of the feet, adhesive mounting is not recommended. Professional independent testing demonstrated that the Snojax I holds 1,800 pounds when attached with #14 screws. All tests were performed simulating realistic snow loading conditions applied to the face of the guard.


This patented product has stood the test of time and is an aesthetically appealing, low cost solution to the problem of sliding snow and ice on metal roofing. The Snojax I has been a proven and reliable solution for decades and is still popular with our contractors and DIY homeowners alike. The Snojax I remains a staple among the snow guard industry and is still heralded for its high quality and unique styling. This clear guard is still a top seller even after all of these years. We have the originator, Jack McMullen, to thank for that.

untitledFor over 35 years, we have been bringing the best in polycarbonate snow guards for your roof. One of our guards has stood out among its peers to become our most popular guard that we sell to this day. The American made SnoBlox Deuce has revolutionized the polycarbonate snow guard industry with its low profile forward mounted 2.5″ high face and its sleek 1.5″ wide waffled tapered back base that fits most roof panels without rib straddling. This patented product has stood the test of time and is an aesthetically appealing, low cost solution to the problem of sliding snow and ice on metal roofing. Its mounting versatility allows it to be both mechanically attached and adhesive mounted on screw down roofs with a 1.5″ flat area. Starter points are provided for mechanical fastening and eliminate the need for pre-drilling when used with a self-tapping #14 screw. This guard is also able to be mounted with adhesive on floating standing seam roof systems, where mechanical mounting is not appropriate. The waffled base provides almost triple the bonding power of a smooth bottom guard in its size category. This guard also has the added benefit of being produced in 11 stock colors along with a recycled finish, known as the Ecoblox. Professional ATI tests demonstrated that the SnoBlox Deuce held 3456 pounds when attached with #14 screws and 1379 pounds when attached with the SB-190 adhesive. All tests were performed simulating realistic snow loading conditions applied to the face of the guard. When installed with adhesive, the best time of year to install these guards is in the late spring through summer. It is important to install with Surebond SB-190 and allow for approximately 28 days at 50 degrees Fahrenheit to achieve the proper cure. Layout assistance can be found on our online calculator at Because of the Deuce’s almost universal fit potential, this snow guard is preferred both among our wholesalers and also our consistent customers who order in bulk quantities to take advantage of our volume-discounts.
SAM_0027 The Deuce’s 1.5″ base is designed to make it the most universal fit snow guard in the industry.  It is compatible with every metal panel in the industry that allows for a 1.5″ wide flat mounting area.  For this reason and also because it is available in multiple colors, the SnoBlox Deuce makes it our #1 seller. The next time that you are looking for a snow guard for your project, think of the SnoBlox Deuce!

Snow guards are about the last thing on any consumer’s mind, now that the warmth of spring is upon us. Winter’s snow and ice are being forgotten as hats, gloves, and boots are being replaced with windbreakers and sandals. This winter, however, was a big one and should be remembered. If you are a home or building owner, this is the most important time of the year for you to begin thinking about and researching snow retention while it is still fresh in your mind.

Many of our customers assume that we are busiest during the winter months, but that simply is not true. This is due, almost entirely, to the fact that many of our products cannot be installed during the winter. Now that the temperature is beginning to rise, we are heading into the perfect time for installation of our polycarbonate guards with adhesive.  Surebond SB-190 is the industry standard for snow guard installation and the one that we trust for use with our products. Its tensile strength, long life expectancy, and ease of application make it the preferred adhesive here at SnoBlox. Warm temperatures, however, are critical for this adhesive to function properly. Surebond SB-190 requires approximately 28 days at 50 degrees (Fahrenheit) or above in order to achieve a proper cure. While temps below 50 degrees will not harm the adhesive or guards, it will extend the curing time.

Some of our competitors attempt to discredit polycarbonate snow guards with horror stories of failures. The part that they won’t tell you is that these failures are almost always attributed to not obtaining or following a manufacturer’s project-specific spacing layout. Every roof is different and the slightest change in pitch, panel length, or ground snow load can have a major impact on the performance of your system. Not every roof can get away with a single row of guards (regardless of the method of installation). Most projects require multiple staggered rows up the slope of the roof. The main purpose of a high quality snow guard is to hold snow and ice in place, allowing it to melt and then drain into your gutters. This field-style layout allows the weight of the snow and ice to be equally distributed over the entire roof’s surface. Snow guards that are only installed along a roof’s eave are often tasked with playing goalie to heavy, high-momentum snow and ice packs. These fast sliding avalanches will often disengage snow guards from the roof and can also cause them to break. This is considered improper installation and often results in higher costs for repairs than what may have been saved by initially cutting corners.

Break Up Dangerous Sliding Snow and Ice With SnowBreaker



Winter Storm Jonas recently blanketed the East coast with historic snow levels, rivaling snowstorms of the recent past. Over 14 states received more than a foot of snow. Mount Mitchell, North Carolina took the crown at 66 inches from the storm — a new record for them, beating the 50 inches they measured during the Blizzard of 1993.  At least 6 locations in the East reported their largest record snowfalls ever as well. Allentown PA, BWI, Harrisburg PA, LaGuardia Airport, JFK Airport, and Newark NJ all beat previous records dating as far back as 1888. Storms like this one can be a harsh reminder of just how critical snow retention is for both new and pre-existing buildings.

Typically, our customers are able to solve their roofs’ snow and ice problems with one of our standard snow guard systems. Whether polycarbonate or stainless steel, the majority of the roofs that we sell products for can accommodate a guard system that equally distributes the load of snow and ice over their entire surface. This allows for the snow and ice to melt in place and drain safely from the roof into the buildings’ gutters and downspouts. There are circumstances, however, when our customers may choose to not keep the snow and ice on their roof for an extended period of time. In these cases, a different product is needed to help the snow and ice safely shed from the roof.SAM_0473

IceBlox Inc. has developed the perfect solution for these situations with our revolutionary product called SnowBreaker. As snow and ice shed from a roof, these cost-effective products minimize the danger by slicing the frozen snow and ice into small pieces.  The forward cutting edge and the tucked-back rear support form a triangular shape that acts like a fin to split up the frozen precipitation.  SnowBreaker’s design allows the snow and ice to slowly shed itself from the panel while the guard slices it into safer, smaller pieces before reaching the roof’s edge.  This can be most beneficial in areas where winter weather conditions can sometimes exceed the roof snow load design.

An added benefit for our customers comes from the ability to install this product using 3 different methods of attachment. Those with standing seam roofing, where mechanical attachment is not an option, can install the SnowBreaker using Surebond SB-190 adhesive. (Keep in mind that installation using this method requires 28 days at approximately 50 degrees Fahrenheit to achieve proper curing). Customers with exposed fastener roofing have the choice to use the adhesive method or mechanically with screws. The SnowBreaker’s design includes molded starter points for easy installation using #14 self-tapping fasteners. For customers who do not wish to penetrate their panels, but also cannot meet the temperature requirements for Surebond SB-190, there is still one other method of attachment available.

The SnowBreaker 3M – Peel and Stick, uses pre-attached 3M brand adhesive tape. The cutting edge design reduces significant sheer load so it is an ideal peel and stick solution for year round and/or winter time installation. Customers who purchase the SnowBreaker 3M are provided with adequate sealant for application around the entire perimeter.

The SnowBreaker and SnowBreaker 3M are revolutionizing the industry one building at a time…will yours be next? See our entire line of snow guards here.

IceBlox Inc. Introduces Standing Seam Vent Pipe Guard Kit

vs ad

Sliding snow and ice are major problems for chimneys and roof ventilation pipes on both commercial and residential buildings. Damage, such a bending or shearing, is a common and often expensive occurrence. VentSaver products will help prevent crushed vent pipes by splitting and diverting the snow. Unlike snow guards, this ingenious vent guard product also adds support and strength to your vent pipes, chimneys or masts. The innovative fin design cuts through packed ice and snow, causing the snow slide to divert around the pipe, and to assist in shedding the snow and ice from your roof. Installation is quick and easy. VentSaver is made from quality non-corrosive, powder-coated aluminum, stainless steel and aircraft cable. The 151 series will fit any roof pitch and any standard size vent pipe (1 1/2″, 2″, 3″ and 4″).  The 383 series will fit any roof pitch and an infinite array of sizes between 1-14″. The beauty of the 383 series is the variety of applications it will fit as well as the ease of installation. The HD, like the 383, can work on any roof pitch and also includes the added benefit of the optional wing kit. All 3 of these VentSavers eliminate the need for unattractive, costly crickets and may be installed on any existing roof as well as new construction.

Now our valued customers can install these great products onto their standing seam roofs as well! We are proud to introduce the Standing Seam Vent Pipe Guard Kit as the newest addition to our product line. This is an adjustable-fit mounting plate that secures to a roof’s standing seams with (4) non-penetrating RCT seam clamps. It allows the use of the Ventsaver 151, 383, or HD to be used without penetration. It utilizes a custom fit Ice Ramp, to protect the base of the pipe from sliding snow and ice damage. The fin of the Ventsaver protects the upper portions of the pipe. The all-aluminum SS Ventsaver kit is manufactured in the USA and uses stainless steel set screws and fasteners.

Please check the “Panel Matrix” for a list of standing seam panels that these products are now compatible with. This product works best when combined with one of our snow guard systems. Please visit our website for more information on our snow guards.
