To install roofing starter strip, you need to place it along the eaves of your roof before adding shingles. A starter strip is a special material that goes under your first row of shingles. It helps water drain properly and keeps your roof from leaking at the edges. Most roofers use starter strip on every roof replacement because it adds protection where your roof needs it most. Installing it correctly takes just a few steps.

What Is a Starter Strip?

A starter strip is a piece of roofing material placed at the bottom edge of your roof. It looks like a shingle but works like a seal. The strip catches water and sends it into your gutters instead of under your roof.

According to RubyHome, the average roof replacement costs $9,526, and using the right materials like starter strips helps protect your investment. Starter strips make your roof last longer by stopping leaks before they start.

First, make sure your roof deck is clean and dry. Remove any old nails or debris. Then snap a chalk line at the eaves to mark where your starter strip goes.

Next, cut your starter strip to fit your roof width. Some starter strips come pre-made as rolls. Place the sticky side down along the eaves. Use a nail gun to nail it every 8 inches. Press it down firmly to seal the adhesive.

Make sure the starter strip hangs slightly over the edge of your gutters. This helps water drip into your gutters, not behind them.

Common Starter Strip Materials

Starter strips come in different types. Here are the most common ones:

Material Type	Best For	Cost Range
Asphalt Roll Stock	Budget builds	$4.25, $4.95 per sq. ft.
Self-Adhesive	Quick install	$5.00, $7.00 per sq. ft.
Metal Edge	Premium homes	$8.00, $12.65 per sq. ft.

According to industry data, asphalt shingles account for about 80% of roofing projects in the U.S., making asphalt starter strips the most popular choice. Metal starter strips cost more but last longer on high-end homes.

Why Starter Strip Matters

A starter strip is your roof’s first defense against leaks. According to industry data, leaking causes 33% of roof replacements nationwide. A good starter strip stops most water from getting under your shingles at the edges.

According to the National Association of Home Builders, the average U.S. roof size is 2,647 square feet. Even on smaller roofs around 1,600 square feet, a starter strip is essential. Skipping this step can cost you thousands in water damage later.

Professional roofers always use starter strips. It is part of the right way to build a roof that lasts. Most roof types, like asphalt shingles that last 20 to 30 years, need a starter strip to reach their full lifespan.
