why not just bend the aluminum so it is tucked under the shingles?
If drip edge isn't installed, you will get | blown, or dripping infiltration which will eventually cause substantial | damage.
that's BS my wood shingled roof has no drip edge haven't seen any substantial damage yet (20 yrs.later). it's the gutters that seem to always cause the damage from what I have replaced for customers.
| | There are different types of drip edge. Do _not_ let anyone install a "c" | channel drip edge, under any circumstances. I could write pages on why not | to have this type of drip edge. Even in my area, city localities will not | let this type of drip edge installed.
sometimes for the right application "C" channel is needed, it all depends on the trim. for instance, on a bitumen roof application it hides the nailing strip around the perimeter.
| | As far as the first roofer telling you his version. I say BS, and this is | coming from someone that had close to 30 years in the business. | | Drip edge isn't really isn't "cheap", as some others have said. It's priced | about 28 cents a lineal foot, at suppliers in my area. If you have a hip | style home, it adds up fast. But, having an after-thought about getting it | installed after a new roof is installed, is too late. | | As a side note: Shingles are supposed to over hang the drip edge, never | even with it. | |
I am a firm believer in drip edge for the bottom so it overlaps the fascia board but not on the rake boards unless it is a re-roof (it hides the edges of the original roof nicely).
