 2~12 Pitch
and Up ~ 15# and 30# felt is used underneath the regular
asphalt shingles. 30# is for slopes between 2 and 4~12 pitch or
a 9~12 and above. Watch the roofers as they tear off because
this is one of the most common roofing short-cuts. On some roofs
it is possible to remove the top layer of shingles only, then
nail the new shingles on top of the same old felt. It could save
the roofing company as much as
$10.00 per square when this occurs
so if you do choose a roofing contractor, ask for a complete
tear off and make sure it’s in writing. |

 Cold Applied
~ Just Peal off the back and
it sticks to the plywood and when it heats up it seals all the nail holes.
It sounds great but in most cases it is not. This is a commonly used product
for add-ons or sheds etc. When the pitch of a roof is lower than 3~12 there
is nothing that will keep the water out better than a torch applied modified
bitumen. Laying this stuff down before using plain asphalt shingles is a
nightmare waiting to happen. |
