"I
put
on the Retro-Split Collar last Saturday and it worked
perfectly. I covered the original flashing with
fresh caulking so it was ok for the Retro-Split Collar.
It's a good product and I would recommend it to anyone
doing retrofitting. Thanks again for the email and
follow-up phone call. I appreciate the good customer
service."

Your
storm collars do not "lock" onto the roof's structure.
Why is it important for the system not to lock onto the roof's
structure?
That
is a good question to ask. The answer is based on the amount
of stress that develops when a structure or building moves
in relation to the penetration. Since the penetration is
not part of the structure, it will move at a different rate,
and can even move in a different direction. The amount
of stress that is developed on a fixed point can be tremendous,
measured in thousands of pounds per square inch. With this type
of stress, something has to give. Either the penetration, roof
or seal will fail. An example is a pitch pocket. The pockets
encase and hold onto the penetration in asphalt, cement or both. Even
a relatively small movement such as heat during the day will
create so much stress that the “glue” holding
onto the penetration will give way. This is now a leak. A
lot of roofers don’t realize how much a roof moves each
day. On a typical roof the manufacturer's published expansion
coefficients equal 2% (some are 4%) of the roof area. On
a 100 foot roof (100 feet x 12 inches = 1200 inches), this mean
the amount of movement each day can meet or exceed 24 inches
of movement between the coolest and the warmest time of day. Since
the roof will keep expanding and pushing until it reaches the
24 inch growth rate, the stress on everything attached to the
roof covering will be under extreme amounts of pressure or stress.
This is called slow growth stress while an earthquake is immediate
and super strong.
After the 1994 earthquake in Northridge California, we spent
many days repairing flashings that had pulled completely
out of the roof. 'Exploded' is even a word we can use for
these roof failures. The roof just snaps under
the stress.
If the penetration and the roof are not connected, and the
movement takes place, nothing hurts the seal or the roof. When
the movement stops, or the or the temperature cools, there
is nothing to repair because of the wiggle room created by
the loose fit.

How
long have your waterproofing products been in use?
Our first
product, the Standard Storm
Collar, was designed
to waterproof the three hole line sets from HVAC penetrations.
The first of these was installed in 1995. Our Retro-Split
Collar was used in installations
beginning in 2001, and our Retro-Spin
Flashing had
its first application in 2004.
|
Can
your waterproofing products be used on metal roofs?
Yes, the Retro-Spin
Flashing is an ideal choice for installing
a flashing on typical roof penetrations including standard
vent pipes up to 2 7/8” O.D. Additionally, our Retro-Spin Flashing
can be painted to match the roof it is installed on.
|
I
have a re-roofing project that will begin immediately. Where and
how soon can I get your waterproofing products? Are they immediately
available or do they need to be special ordered?
All of our products are sold
at roofing supply houses and distributors nationwide. They are
also available online. More and more roofing supply
houses are offering our waterproofing products to their customers.
We also have several stocking distributors located throughout the
United States. However, if you do not have a distributor near
you, you can order from one of our online distributors.
If all else fails, email us
(allstyle@spinflashing.com)
or call us (805-557-1225).

I
have a roof with a penetration that needs to be waterproofed, and
your product would work great for this. However, you do not offer
the shape I need. Can you custom make a shape for me?
The Retro-Spin Flashing
is available for penetrations up to 3 inches in diameter.
Retro-Split Collars are available in three sizes which waterproof
diameters up to and including 12 inches. This range of sizes can
accomodate penetrations with any geometric shape that can fit inside
3, 6 or 12- inch diameters. In the event a non-round shape is
required, please call for custom requests.
|
Can
I paint your storm collars and flashing to match my roof?
The metal Retro-Spin Flashing
can be painted. We do not recommend painting EPDM Rubber parts,
however, these can be made in a variety of colored rubber such
as white, blue and green. Our white collars have
proven to be very popular.
|
Why
would I use your Storm Collars when I can use pitch pockets?
There are several reasons for
using our Collars instead of pitch pockets. A well-made pitch pocket
is not practical or cheap. It needs to be site-fabricated and installed.
Fixed penetrations require field installation and soldering and
with high labor costs and the potential for poor workmanship, this
is not a practical solution. Decent pitch pocket fillers require
a fast curing cement, and a top coat of a two-part polymer sealer.
These products are not cheap, and require installation time. Finally,
when finished, you still have a pitch pocket, which the National
Roofing Contractors Association (NRCA) technical specifications
and drawings show covered over with a good quality Storm Collar.
Therefore, save yourself the time and expense by using a Storm
Collar over
a Retro-Spin or
Standard Flashing.
In the event
an old pitch pocket leaks, a smart repair can be done by installing
one of our Retro-Split Collars over the top of the pocket, covering
it over just as it is shown in the NRCA manual.
The HARK (Handbook
of Approved Roofing Knowledge) does not recommend the
use of pitch pockets because they leak. Additionally the National
Roofing Contractors Association (NRCA) states that "Pitch
pockets or pans, by their design, are not intended to be continuously
watertight. Their use should not be encouraged since better methods
are available to accomplish the same end. Pitch pans or pockets
require frequent inspection and maintenance, and usually a great
deal of damage can occur before the leak around a pitch pocket
or pan is evident."
In the long run, a pitch pocket will cost you more money due to
fabrication and installation costs, and the time it takes to go
out on maintenance or leaking roof calls.

As
a roofing contractor, I have found that HVAC penetrations generally
leak. How do your line set storm collars work?
After studying the leaks
that originated from HVAC penetrations, it became obvious that
the only way to stop water from leaking inside the insulation and
between the tubes was to isolate the individual lines and seal
them separately. Our EPDM
Storm Collars have a
hole for each penetration. Each hole has a nipple, and a clamp
secures the nipples onto the individual roof penetration tubes.
Our Collars create a dam that water can't flow past, so the water
stays on the roof. They counter flash any roof jacket without creating
a mechanical connection to the roof. This allows for movement of
the penetration, which can occur from seismic events or heat-related
expansion and contraction. Finally, if the roof flashing jack is
configured with an 8 to 10 inch rise, then there is no need to
install roof curbs in order to meet the National Roofing Contractor
Association's (NRCA) height standards. Storm Collars can seal many
different multi-pipe roof penetrations and do it better than any
other system on the market today, and at an affordable price.
|
Why
do you use EPDM rubber on your Collars?
Our Collars are made
in the United States from first quality, non-recycled E.P.D.M.
rubber that is exceptionally resistant to heat, ozone and acid
rain environments. For long life of 20 years, no plastic
resin materials are acceptable on any part of our Collar assemblies.

Why
would I use the Retro-Spin Flashing Kit when I can just cut
a flashing, put it around a pipe and mastic the cut?
Our Retro-Spin
Flashing Kit is a system that allows for the quick and easy
installation of a brand new, durable, fully waterproofed and
visually attractive roof flashing around all types of roof penetrations,
without having to disconnect a service stack, or take apart a
permanent attachment. The alternative is a site-fabricated, unattractive,
gooped-in-place cut flashing which will cost plenty with leak
and repair callbacks.
Until now there has been no easy way
to replace the flashing on penetrations such as the electric service
mast, because flashings don't open up and are installed over the
top of a pipe. To get a new flashing installed the old way, the
electric service for the entire house would need to be turned off
for a day or so. However, with the Retro-Spin Flashing, simply
spin it on around the pipe and spin it closed. All you'll need
is a hammer and nails. It's that simple. The electricity doesn't
need to be turned off and you won't have to worry about callbacks.
Roofing professionals have an opportunity to upsell the customer
with an easy way to replace all their old flashings which may cause
problems down the line. Show the customer how the Retro-Spin Flashing
operates. Explain that it is your normal practice to do high quality
roofing, and that includes replacing all of the pipe and vent flashings
on a job.
Installing roofs professionally with high quality
and innovative products allows the roofing contractor to spend
less time and accrue higher profits from each job. A smart contractor
will offer his customer options to improve his or her roof. Sales
options add value to the job through their higher margins. A Retro-Spin
Flashing Kit is the classic value-added product. Simply offer one
on every job that needs one, have a happier customer and increase
your profits. The Retro-Spin Flashing is both visually attractive
and operationally effective. The end result is an attractive roof
that is completely waterproofed, providing a win for you and a
win for the customer.
