How to Stop Squirrels and Other Animals From Getting Into the Loft/Attic

I’ve spent over 18 years working in the construction industry, initially in the roofing industry before moving onto home improvements and renovations.

I have personally seen dozens of homes that have experienced problems caused by squirrels and other pests entering the loft and causing carnage.

Squirrels need to chew regularly to keep their teeth from growing too long, they will grind their way through almost any material, including lead, plastic and wood.

Here are a few photos of the damage these critters can cause:

If you don’t take steps to block squirrels, you can expect:

  • holes in fascia and soffit boards.
  • noises in the loft/attic.
  • birds gaining entry via the holes and nesting in the loft.
  • damage to cables, including tv aerial cables and power cables to light fittings.
  • roof leaks.

The Most Common Loft Entry Points For Squirrels

Squirrels almost always enter the loft/attic via the eaves, this is the lowest part of the roof, often where the gutter is located.

These pests usually sit in the guttering and chew through the top edge of the fascia board.

This hole is then used an entry point for other squirrels and also birds that then nest in the loft.

These photos may help to explain how they gain entry:

Prevent Squirrels From Entering the Loft

There are two products that will stop squirrels in the tracks:

  • thick metal
  • concrete

Roof tiles located at the eaves level can be bedded onto concrete/mortar to prevent squirrel entry:


As the fascia boards are a common entry point for squirrels, the back of the board should be reinforced with a metal strip:

Is it Possible to Block Squirrels From Inside the Loft?

Due to the limited amount of space in most lofts at the eaves, it’s almost impossible to block the entry points from within the loft/attic.

In most cases, the entry points need to be blocked from the outside, as you can see from the photos on this page.
