Many homeowners don’t know it, but the pitch of their attic can affect the roofing options available to them. Whether you’re building your home from scratch or looking to replace the roof on a house you bought, it’s essential to keep in mind the pitch of your attic. Depending on how steep or low it is, you may have limited roof options, so have a look at the details below from the best roofer in Orange County.

How Does Attic Pitch Affect My Roof?

Usually, the pitch of your roof will follow that of your attic. To do otherwise requires a lot of material that is unnecessary. As such, most roofers will pitch your roof accordingly. This means that if your attic has a low pitch, your roof most likely will as well.

The pitch of your attic doesn’t just affect the types of roofing materials you can use, though. It also influences maintenance needs and costs. Low-pitched roofs require more frequent maintenance as they’re more likely to experience drainage and other issues. This means they tend to have more expensive upkeep.

Conversely, low-pitched roofs require less material than steep roofs. When installing your roof, this means you’ll spend less on materials and labor. 

What Are My Roof Options With a Low-Pitched Attic?

Low-pitched roofs and attics have a pitch of 8/12. Upwards of 8/12, you’ll slowly get into steeper and steeper roofs. Both types of roofs have their limitations, but we’ll start by discussing the limits of low-pitched attics and roofs.

Low-pitched roofs often have difficulties draining water, so more water-proofing measures are put in place before laying down the actual roofing material. As such, the lowest-pitched roofs, those with a pitch of 2/12 are extremely limited. Roofs that are anywhere between 2/12 and 8/12 will have a few more options, though still limited.

For extremely low-pitched roofs, your options will typically be a modified bitumen rolled roofing or metal roofing. Shingles on low-pitched roofs often cause problems and many shingles will have a pitch requirement of at least 2/12.

What Are My Roof Options With a Conventional or Steep-Pitched Attic?

Conventional and steep-pitched roofs present fewer drainage issues, so you have more options in terms of what roofing materials you can choose. Conventional pitched roofs are generally around 4/12, while anything above that is considered steep pitched. 

If your roof structure is strong enough to handle the weight, tile, and slate make for very beautiful, long-lasting roofing options. However, they weigh a lot and can strain your roof’s structure, so it’s vital to ensure that your roof can accommodate the weight.

Other roofing options for steep-pitched roofs include concrete tiles, shingles, and metal. It depends on what type of budget you’re looking at.

When weighing your options, check if the roofing material you like has any restrictions. Some materials may not do well on particularly steep-pitched roofs, or they may require additional steps upon installation. Looking into this in advance will prevent you from being unpleasantly surprised when your roofer breaks the news to you. 

Which Is Better: Low-Pitch, Conventional, or Steep-Pitch Attics?

It really depends on your preferences and the local climate. Low-pitched and flat roofs will have a hard time in wet climates because they can’t shed water as easily. However, they can be great in hot, sunny climates because they allow for easy solar panel installation. 

Steep-pitched roofs require much more material and can be costly, but you won’t have drainage issues.

Conventional roofs are the most common as they offer a solid middle ground and are relatively easy to work on.
