<DIV><FONT face=Arial>Hi Benn,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>I have never tried a torch on comp. shingles (nor do I
believe I should). What I have used, even in freezing Midwest weather, is a heat
lamp. When it is windy you need to fabricate/construct some type of "dam/shield"
to minimize the wind effect. This technique is potentially even more
involved than the torch but certainly less concern about collateral damage.
Even more important is to use a flat bar to work your way through the glue
strip rather than tug on the shingle itself.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>What have you gained with a great solar installation
if the end result is a roof leak? I promise you, whatever good the solar elec.
or solar thermal brings the owner, that benefit, in the owner's mind, will
be lost if you create a roof leak. Moreover, the roof leak may not be
readily apparent in the living quarters until some time after the
fact.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>There are a number of new mounting products on the
market today, hopefully all better mousetraps.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Good luck.</FONT></DIV>

shingles</DIV>
<DIV><BR></DIV>
<DIV>salute, </DIV>i was inspecting a (~3yr old) 2/12 pitch roof for an
upcoming install that was going to have flashed roof connection points and
noticed that i could not lift up any of the shingles for installing the
flashing. the sealing strip that holds the upper shingle to the one below it,
is aggressively stubborn. i tried several in the area of the array
location and they are all sealed down very well, much better than any other
comp shingle i've come across, which typically lift and separate from the
'sticky strip' with a careful little tug on the shingle. all the ones i
tried began to tear the back off the top shingle that i was trying to lift.
i'm told these are a higher quality comp shingle and are well suited for
low pitch roofs, they have a 35 yr warranty.
<DIV>
<DIV><BR>
<DIV>i contacted the shingle mfg. tech support and after explaining what i was
doing his suggestion was literally "try lifting them when its warm out then
try when its cold out, see if that works.".... thanks tips!<BR>my first
thought was to use a torch to heat and soften up the shingles' sealing strips
that i needed to lift. i'm not surprised that the shingle tech did not
endorse this method. i'm not thrilled about it either. just having a
propane bottle and torch on the roof, risk of overheating (burning) the
shingles, extra time to do this, are things i'd prefer to avoid. </DIV>
<DIV><BR></DIV>
<DIV>i'm sure if done carefully this method would work, but i'm a little more
cautious than just trying it without asking around so i've been contacting a
few roofers i've worked with, as well i'm wondering if any of you have
come across this issue of having to lift particularly well-sealed comp
shingles and how you have dealt with it.</DIV>
<DIV><BR></DIV>
<DIV>if the consensus is to stay away from the torch then i'm prepared to go
with the good ol' l-feet on this one.</DIV>
<DIV><BR></DIV>
<DIV>cheers,</DIV>
