Question For You Roofing Experts

Laketahoedan

I am rebuilding this shed roof entry and it is so small 4'x8' i decided to roof it myself.



What I am not sure about is the starter course using Certain Teed "Carriage House" comp shingles.

I had to order them from my supplier and did not order a pack of starters. I have not picked them up yet (over an hour away from me) and am not sure if I should bother getting them or not till I figure out if I need to order starters.

Can I use the shakes as starters or will the color be different etc.

Any other tips are appreciated.

Cheers

Here is the instructions for installing the Carriage House Shingles.

Cedar Shakes would NOT be appropriate to be used as the starters. But, since it is just a porch overhang small roof, if you have Cedar Shingles, NOT shakes, then you might want to try them out before you take that one hour drive.

You needed to go to the builder contractor link, instead of the home owner link.

I would order the proper starters for these because of its design.Anything else would look odd IMO

Cedar shakes?

I said certain teed carriage house comp shingles.

I was wondering if the shingles will work as starters or not? Or maybe salvage from the old roof.

Thanks for the link, I just found that same pdf as well and printed it out to read over.

Pretty standard for a starter course......Easy as pie. Buy a bunch-a blades. Hook-Blades.

Run them up the rake as well. Drip edge??????

I would use standard starters, just make sure the seal strip is low and the fasteners are just above the sealer strip.

I've done this before and you really can't tell the color of the starters from the ground.

That is what I thought but another contractor told me he usually orders separate starter shakes. I suppose that is for a different brand?

One last question, ( i am sure I will find it studying up)

The underlayment goes over the drip edge right? the existing roof has the underlayment under the drip edge?

just what I thought, and common sense would dictate.

Any ideas how to make the connection to the house water tight.?

It is T111 you can see how they had it before.
They had the flashing over it then a piece of 1x4 above that with all kinds of caulk and henrys

Someone will give me c*#p about this......... Cut a shallow groove or channel the 111 the length of the overhang. Tuck a the 1/4 to 1/2 inch, 90 degree bend you make in a SOLID piece of flashing and caulk PROPERLY.


As one might do on brick. Any other way, IMO, will wick, divert or channel H2O the wrong way.

It appears as though that it is the lack of proper flashing that caused the failure of this roof structure.

This roof failed because of a piece of ice the size of a volkswagen crashing down on it. The 4x4 supports (legs) broke through the decking. I have reinforced the decking an am going to install a gutter and heat tape to the roof above.

I thought about cutting a kerf into the siding but what about the t111 grooves? should I cut into those ~1/8"

Would I bend the flashing to go into the groove or cut the groove at an angle (6&12) so it slips up into the T111.?


Thanks for all the help Malco and others

An angle AND the bend is best!!!! But you gotta have the bend. Fill the channel with caulk, whatever you choose to use, insert the flash, tape in place. After it has cured, go back and caulk again.

Drip edge under the felt paper at the bottom. Drip edge over the felt paper on the rakes. I see very few roofs around here that have it right.

I dislike T111 in these instances as the roof will likely outlast the siding.

A kerf is good but in the past I have cut entirely thru the t111 and used a Z bend so the counterflashing turns up behind the t111. I nearly always favor counterflashing over the flashing proper instead of one piece. Usually takes a little wider slit. It's all kinda sucky for long term with T111.

Good call AH! Good call!

No you did not. See the next quoted response.

When someone mentions "Shakes" to a roofer, either it is Cedar Shakes, or the after effects from St. Patricks Day binge drinking.

You need to cut in a wide enough groove to install an oversized "Z" flashing, which has enough of an extension downward to counter-flash the roof-to-wall apron flashing that needs to be installed.
