Will My Garage Attic Even Support the Weight of Storage?

If you’re considering using your garage attic for storage, you’ll first want to make sure that the space can support the weight of your belongings.

Here are a few things to keep in mind:

  • The Roofing Materials Used – The type of roofing materials used on your garage will affect how much weight the attic can support. For example, asphalt shingles are much lighter than metal roofing.
  • Your Roof’s Pitch – The pitch of your garage’s roof will also affect how much weight the attic can hold. A steeper pitched roof can support more weight than a shallower pitched roof.
  • The Number of Supports – The number of trusses or other supports in your garage attic can impact how much weight it can hold. More support means more weight capacity.
  • The Weight of the Items Stored – Your garage attic joists should be strong enough to allow more lightweight items, but you should avoid weighty objects such as large furniture. Additionally, spread out the weight evenly to prevent structural stress.

If you’re not sure how much weight your garage attic can support, it’s best to consult with a professional. They will be able to assess the space and give you a better idea of what it can safely hold.
