I have a pipe going through my metal roof. What do I need to know before I order? Watch this video:
I have my Flashers®, now what do I do? Watch this video:
Can Flashers® pipe flashing be used on a composition roof? No. Flashers® pipe flashing are designed specifically for use on metal roofing and siding.
Can I use this pipe flashing on a canvas tent? No. Flashers® pipe flashing are designed specifically for use on metal roofing and siding. Installing a pipe flashing too close to the heat source will result in catastrophic failure.
I have a steeply pitched roof. Will Flashers® pipe flashing work? Yes. In this case, we recommend using the largest size available for your pipe diameter to ensure there is enough rubber to accommodate the steep pitch. Click to view our Size Chart.
My inspector says Flashers® pipe flashing aren’t approved for use on Type B Vent Pipes. Is this true? No. Flashers® pipe flashing are indeed approved for use on Type B Vent Pipes. Our products have gone through rigorous testing by IAPMO R&T and are in compliance with the Uniform Plumbing Code (UPC) and International Plumbing Code (IPC). Click to view our IAPMO R&T Certificate of Listing.
Can Flashers® be used on a single wall vent pipe? In certain applications, yes. If it is a non-heat-producing application, our EPDM pipe flashing will work. If the application is heat-producing, specific steps must be taken to ensure that the pipe flashing is not at risk of failure. The outside temperature of the pipe should never exceed the approved temperature range. Exceeding the temperature range risks failure.
Will Flashers® work on a regular shingled roof? No. Flashers® brand pipe flashings are designed for use on a smooth, non-porous surface, such as metal roofing or siding. It is designed to be attached with threaded fasteners and sealant to create the optimal watertight seal. Click here to see our Installation Instructions.
Will Flashers® pipe flashing work on metal roof with 10″ pitch? Yes, Flashers® pipe flashing will work: For a steeper pitched roof such as yours, we suggest using the largest size available to fit the pipe size (outside diameter) that is being used. The rubber fold around the base allows for flexibility in installation.
I have a wood heater with 6” single wall pipe I need to go thru metal roof. Will this product hold up to 250 degrees continuously? For a high-temperature application, a Silicone Flashers® brand pipe flashing is what we would recommend. Silicone Flashers® pipe flashing are designed to handle temperatures from -100 to +450 degrees F. Silicone is available in both Orange High-Temperature and Grey High-Temperature options.
Can I put this flashing over a single-walled pipe? I am worried it will melt. Silicone High-Temp Flashers® pipe flashings are designed for applications with temperatures ranging from -100 to 450 degrees Fahrenheit. If the single wall pipe is rated within these temperatures, and the Flasher is installed an ample distance from the heat source, the silicone pipe flashing will work.
Can this flashing be used for wood stoves? For a heat application, such as a double wall (Type B) or triple wall pipe for a wood stove, a silicone Flasher is a perfect solution on your metal roof. Silicone Flashers® are designed to accommodate temperatures from -100 to 450* F.
Can this be used on a canvas wall tent? If so, how does it install? Flashers® brand pipe flashings are intended to create a water-tight seal on pipe penetrations through metal roofing and siding. Flashers® are NOT recommended for use on applications that exceed continuous temperature ranges (-100 to +450 degrees Fahrenheit for Silicone). Ex: Single Wall pipe with Flashers® pipe flashing mounted close to heat source, such as on a canvas tent. Product failure may occur with temperatures exceeding applicable ranges. Use on projects out of the scope of the intended use or temperature range will void any possibility of manufacturer replacement.
This is an example of a Silicone Flasher installed improperly!!! The pipe temperature exceeded the acceptable continuous temperature range, and the pipe flashing failed: it melted. We would love to produce an invincible product. Unfortunately, all EPDM and Silicone rubber has a limit before failure occurs.
What type of sealant do you recommend for these? We recommend using a silicone sealant for use on metal roofing or siding applications.
Would it be appropriate to use this to flash B vent from propane stove? Flashers® brand High-Temp Silicone Pipe Flashing is rated to service a continuous temperature range of -100 to +450 degrees Fahrenheit. Assuming the Type B Vent Pipe is rated to not exceed these parameters, Flashers® brand High-Temp Silicone pipe flashing is exactly right for the application.
I’m using 6″ double-walled pipe on a 24/12 roof (A-frame). What size will work for this size pipe on such a steep pitch? On a deep corrugated surface or steeply pitched roof, we suggest you choose the largest size available for optimum flange flexibility. For a 6″ Outside Diameter pipe the largest size available is #7, which is what would be suggested. If the outside diameter of the pipe is larger, choose the biggest Flasher size for that outside diameter. Please note, the name/description of the double-walled pipe is not necessarily the actual OUTSIDE DIAMETER of the pipe. The OUTSIDE DIAMETER of the pipe is a critical measurement to confirm to ensure the correct size to use.
Does this product have a warranty? Yes, there is a 20 Year Limited Product Warranty on Flashers® brand pipe flashing.
Can this be installed horizontally for a through-the-wall chimney for my off-grid wood stove? Yes, Flashers® pipe flashing can be installed on metal roofing or siding. With proper spacing from the heat source and an insulated chimney pipe, a Silicone Flasher is a great solution.
Could this be used at the roof peak? Is the ring flexible enough to bend? Yes, our product is flexible enough to bend at the peak of a roof. Using the largest size available for your pipe is a good idea to allow for enough material and flexibility of the rubber to accommodate the bend needed at the peak.
What is the recommended spacing for the fasteners? Fasteners should be spaced every 1″ to 1-1/2″ around the base.
What type and length screws should be used to attach your Flashers® pipe flashing to a metal roof? For a standard metal roof application, a good general size would be 1-1/2″ length self-drilling or self-tapping screw. Screw installation should be every 1″ to 1-1/2″ around the aluminum base of the Flasher.
Will Flashers® pipe flashing work on metal siding (a wall)? Yes. Flashers® brand pipe flashing is intended to create a seal on any penetration through metal. When installed in accordance with our installation procedures, Flashers® may be used on any metal application, whether it be roofing or siding.
I want to change the color of my Flasher. Can I paint it? No. We would not suggest painting Flashers®. Paint can have adverse effects on the product and may cause product failure. Some paints may have chemicals within them that degrade the rubber which could lead to possible cracking and leaking. Painting Flashers® would also void any warranty.
Can Flashers® be used on standing seam roofs? Yes. It is best if the Flashers® are positioned between standing seams.
I have a 5″ Outside Diameter pipe on a 20/12 pitch roof. Will a #3 Flasher work? No. For a steeply pitched roof, we would suggest using the largest size available that accommodates the pipe OD used. In this instance, we would suggest a #6 Flasher. See our Size Chart for reference.
