"Starter Strips - Almost Always Done Wrong!"
| |
You do need a row of shingles beneath the first regular row. Why? Because of the knockouts. Those thin lines in shingles are voids. You can see to the shingle below. Well, on the first row, there is no shingle. Well, there is going to be. You have to take a regular shingle and cut off the first 5 inches. This leaves you with the top 7 inches. Don't take a regular shingle and just turn it upside down. This is wrong! I like to allow the shingles to overhang the edge of the drip edge by 1 inch. Do NOT apply the shingles flush! Water, by capillary attraction, will pull its way up the shingle. |
