Frequently Asked Questions
RoofGoose Vent utilizes a proprietary design for its flat roof vents & low slope roof vents. As a result, we get frequently asked questions about what makes our roof-mounted exhaust and intake vents better than typical roof vents. Read the list of questions below to find out exactly what makes RoofGoose different than most flat roof vents.
All parts are manufactured in New England and assembled in Rhode Island.
Individually and in bulk “gaylord” boxes.
Individual packaging consists of two boxes the sleeve and metal riser clamp are in the first box for installation in the “rough”. The second box will contain the Gooseneck and Storm collar for installation in the “finish”. This box organization minimizes the risks of losing parts on an active and busy job site.
Bulk “Gaylord” boxes can requested for 6″ quantities greater than (25) and 4″ quantities greater than (45). For greater quantities we can create “rough” and “finish” kits to minimize loss and damage. We find the bulk boxes minimize waste and expedite loading materials to the roof. You will find they are a tremendous labor savings when utilized and can be repurposed or 100% recycled. For Quantities greater then 25 units please contact Sales@roofgoosevent.com for Bulk Orders.
Your roofer will determine your ideal method for flashing based on the underlying roof material. Commonly we have seen roofers sealant with a stainless steel hose clamp adhering to the plastic or some have found they prefer to tack weld to the sleeve. Common flashing details similar to any plastic vent termination are suitable.
The insulation provided has an insulation R-value of R-4.7 from the manufacturer and has been tested to ASTM E84.
There are two scenarios of installation for roof terminations.
Scenario 1 is a new construction project where the RoofGoose sleeve is installed in Sequence with the roofing membrane to allow for the roofer to flash to the provided sleeve. once the sleeve is flashed later the mechanical contractor can install the gooseneck and Rain collar over the roofers flashing.
Scenario 2 is a retro fit where the roofers flashing has already been adhered to the metal exhaust duct. in this Scenario the provided sleeve slides over the metal duct to meet the roofers flashing and then the storm collar and gooseneck get installed all at once.
In the insulated models its preferable to use installation Scenario 1 in order to ensure the thermal envelope is continuous from roof deck to the end of the metal duct.
Absolutely. Remove the existing vent hood or field assembled gooseneck and leave only the existing metal riser duct. Ensure the existing duct is long enough to protrude 1″ above the RoofGoose sleeve. If it is short extend the metal riser duct as necessary and if it is too long cut down to required height. We offer RoofGoose Sleeves in two (2) stocked lengths so be sure to check which length you need.
Custom Lengths are available at additional fee minimum quantities apply, please call.
The 2018 International Mechanical Code (IMC) section 504.4.1
Exhaust termination and outlet and passageway size.
“The passageway of dryer exhaust duct terminals shall
be undiminished in size and shall provide an open area
of not less than 12.5 square inches (8065 Millimeter squared)”
The RG4-IE has an unobstructed opening that is 3.75″ in diameter at the in-line damper which does not meet the code requirement.
Temporarily remove the Bug cap and reach into the outlet of the gooseneck. Remove the backdraft damper door and re-install the bug cap at the outlet of the gooseneck. After this your RG4-IE or RG6-IE can be used for intake air.
Instructions are molded into the side of the gooseneck for reference.
The motion to remove the gooseneck is lift up (3/4″) turn counter clockwise (3/4”) and then lift off the end of the sleeve. There is a snap lock that requires moderate pressure/force on the initial up motion. To re-install the motion is the reverse and requires moderate down pressure to engage the locks on the final downward path. Be sure to engage all four (4) locks.
Instructions are molded on the side of the part/s
All caps unscrew with a counter clockwise quarter turn and are reinstalled with a clockwise quarter turn motion.
You do not need any caulk or sealants to install our roof termination. We use stainless steel hose clamps and integral plastic locking mechanism machined into our sleeve.
If you are concerned about water infiltration while the roofer does their work you can caulk the annular joint around the metal duct. In our experience there are many penetrations through the roof that caulk can provide a good temporary seal while waiting for the roofer to do their work.
Yes, you can. We find they are very useful for side wall vent terminations in order to lock in the exhaust duct from being pushed in by siders or other trades accidentally. They are superior in this application because they are very strong and utilize clamping force to hold the duct in place rather than penetrative fasteners. They are available in 4″ and 6″ sizes currently 8″ will be coming soon.
No you can not. The international mechanical code (IMC) mandates that the duct be continues to the point of termination and you are not allowed to utilize plastic ducts above grade except in very limited applications.
Under each product there are details available in both .DWG and .PDF format for use in design documentation and installation guidance.
