How should I do this? My current roof is a standard 3 tab shingle. The new addition will be covered with a Gaf Elk archy type shingles. I am going to buy enough to do the entire roof but am only going to do the addition part of the roof at this time. I know it will look ugly for a few weeks with the two different types and colors of shingles but I need to get it dried in so I can do the wall sheathing and siding.
How should I start my layout? From which end,where the current shingles are and felt begins? This is a hip roof, if you look at the pic with the shingles and felt paper the hip is to the right. Since I have added trim to the fascia the drip edge sticks out further than before so I can’t line up the new shingles with the old.
Here is the way I was going to do. Please tell me if I’m doing it wrong.
1. Where the current shingles end and felt begins I was going to make sure my starter course shingles extended past my drip edge by 3/4″ and make a mark at the top of that shingle.
2. I was going to go down to where the last full starter course shingle would be (hip), make sure it extended past my drip edge by 3/4″ and make a mark at the top of that shingle.
3. Snap a chalk line between those 2 marks and follow this line with the starter course. This should take care of any snake in my fascia. I hope.
4. Start with a full shingle and then subtract the correct amount for the stagger. Start laying them down.
What am I missing?
