Hi there,

I’m reroofing our screened-in porch and its slope is about 2″-12″.  It joins the main roof (which is 4″-12″ slope) of the house.  the joint linking the 2 roofs leaks every rain fall,  and spring.  IKO makes a product that seems ideal to redo the low slope roof (Its called ROOF FAST).  But it doesn’t solve the joint problem.

Would it be overkill to tuck a waterproof membrane under the 30lb tar paper at the edge of the 4-12 roof so that it straddles that joint?  I guess I can only tuck it in about 5″ or 6″ ’til it reaches the point where the asphalt shingles are nailed.  I would then apply the ROOF FAST.  Then I would put a wide aluminum strip the length of the joint that would be tucked in under the shingles and over the ROOF FAST.

How’s that?

Thanks for any response,

Dan
