Do architectural shingles need a starter strip?
People also ask, is a starter strip necessary?
The starter strip is crucial because it adheres to the shingles on the edges of your roof and protects them from the elements. The more protection you can have along the edges of your roof the better, and starter strip shingles provide that crucial extra layer of protection.
Thereof, do you overlap starter shingles?
With the starter shingles laid along the very edge of the roof, run a set of starter shingles along the sides of the roof as well, making sure that those rows come down and overlap the starter shingles you laid at the bottom.
The edge of the shingles should hang over a roof between an inch and an inch and a half — or between a half inch and three-quarters of an inch if drip edge flashing is installed. Too much overhang and the shingles could blow off in high winds; too little can allow water to seep into rake or fascia boards.
