If you still use 30# roofing felt, you're throwing your money away.
- Our synthetic underlayment is 20 TIMES STRONGER than felt - -it won't rip or tear and it won't buckle when wet.
- It's about 10 TIMES LIGHTER than felt so it goes up faster and puts less weight (and stress) on your roof.
- And it's the most slip resistant underlayment in the industry.

Our roofing underlayment comes
with a preprinted nail pattern and alignment guides
and its 48" width makes for a quicker installation.

The underlayment of your roof is as important
as the finish or exterior material you choose. This is particularly
true if you are installing a new roof or installing after
a tear-off of an older roof where you are down to the original
decking. In the case where you are installing a metal roof
over an existing roof, the importance of the underlayment
is somewhat minimized because the old roof materials, as long
as you have determined they are not too uneven or distorting,
will act as a protective barrier between the roof deck and
your new metal roof.
Over the last fifty years or so, most everyone
used a petro-chemically soaked product known as roofing felt.
There are various other names this product has been called
such as "tar paper", "roofing paper",
"felt paper" to name a few. It's all pretty
much the same thing though: a mat of organic or inorganic
fibers impregnated with asphalt or coal tar pitch.
Today's technology brings us a new synthetic
underlayment that is vastly superior in all respects to "tar
paper."
Our synthetic
roofing underlayment comes with a 25-year limited warranty.
It is made from a woven black polypropylene with polymer.
It is UV resistant, the membrane is self-sealing where nails
have penetrated it for attachment purposes and it is slip
resistant.
Let's look at a head-to-head comparison
of our synthetic underlayment vs. the old-school Felt
Paper, shall we?
Synthetic Roofing Underlayment |
|
|
| The amount of synthetic underlayment
needed to cover 10 squares weighs just 28 lbs. This
is 6 times lighter than felt! |
|
| The amount of 30# felt underlayment needed to cover 10 squares weighs
275 lbs! |
|
| Faster, more efficient installation
means less labor cost and less call-backs for the
contractor. |
|
| Difficult to work
with, installation goes slowly, and can subject
contractors to call-backs due to blow-offs, rips,
tears or weather damage |
|
| Doesn't stick to metal roofing. |
|
|
| Withstands extreme hot and cold temperatures. |
|
|
| Lays flat, stays wrinkle-free. |
|
| Stiff and difficult to uncurl. |
|
| Consistently out-performs and out-tests
conventional roofing underlayments, and blows away
old-technology underlayments. |
|
| Do they still sell this stuff? |
|
| Skid-resistant surface is easy to
walk on. |
|
| Can be slippery and dangerous
to walk on. |
|
| Tested watertight around fasteners. |
|
| Not at all watertight around fasteners. |
|
| UV Stabilized and rated for a One
Year Exposure. |
|
| Not UV Resistant and easily damaged
by UV rays. |
|
| Easy to cut and fold around corners. |
|
| Equally easy to cut and fold,
but can tear very easily. |
|
| Unaffected by water and can be left
exposed for several months. |
|
| Absorbs water and should be covered
immediately. |
|
| Extra wide 48" rolls make installation
quicker. |
|
| Narrow-width rolls mean more labor
costs during installation. |
|
| Impervious to insect and vermin damage,
as well as fungus and rot. |
|
| Can be damaged by insects and
vermin, plus the material promotes fungus and rot
due to moisture absorption. |

If you're down to the decking, and just
must save some money, then at least put our synthetic underlayment
on the edges of your roof (eaves/gables) and on the valley(s)
and ridge. In such an application, the eaves, gables and valleys
would utilize vertical runs over the #30 tar paper. While
this application voids the manufacturer's warranty as
it is considered "unstandard" you have at least
protected the most vulnerable areas on your roof.
Pricing:
