How to Level Gutters on Angled Fascia Boards Using T Wedges

Why Fascia Angle Matters and How Wedges Fix It

On many homes, especially those with decorative trim or modern fascia profiles, the fascia board doesn’t sit perfectly vertical. Mounting gutters directly to a sloped fascia throws off your pitch, tilts the gutter forward, and leads to poor drainage and potential sag.

T Wedges fix that by sliding behind the gutter at each hanger, correcting the angle and leveling the entire run.

What T Wedges Do for Contractors

T Wedges are simple inserts that let you mount gutters square to the ground, even if the fascia isn't. They:

  • Keep the gutter level and properly pitched

  • Prevent sagging or forward lean

  • Work with most hanger types, including hidden and strap styles

  • Support water flow through the system without turbulence

Why Use Hallett T Wedges

  • Available for both 5-inch and 6-inch K-style gutters

Whether you’re working a new build or replacing older hardware, T Wedges make sure your install looks good and performs the way it should.

How to Install T Wedges

  1. Assess the fascia angle. If it leans out or back noticeably, wedges are recommended.

  2. Position your hanger or bracket as normal.

  3. Slide the wedge between the back of the gutter and the fascia at each hanger.

  4. Fasten through the gutter and wedge into the fascia.

  5. Repeat for each hanger along the run.

The goal is to create a flat, even line across the entire gutter system. Consistent wedge placement ensures reliable support and smooth water flow.

FAQs

Do I need a wedge at every hanger?
 Yes. Placing one at each hanger keeps the gutter level and supported throughout.

Will these work with a drip edge or roof straps?
 Yes. T Wedges can be used behind drip edge and with strap hangers when needed.

Can T Wedges fix extreme angles?
 Standard models handle fascia angles up to about 22 degrees. For steeper slopes, some adjustable options are available.
