If you’re a homeowner, you’re probably already aware of how much the value of your real estate is affected by the condition of your roof. Nearly all real estate transactions require a roof inspection, and there’s a reason for that: replacing a roof is a considerable investment. That’s why it’s so important to hire a reputable, knowledgeable Portland roofing contractor for your new or replacement roof.
However, when in doubt, consult your local roofing contractor and ask questions about what roof type will work best for you. Here’s a guide to get you started:


Generally, flat roofs aren’t appropriate for the Pacific Northwest due to the amount of rainfall we receive each year. A flat roof’s construction is critical to its function, and a properly installed flat roof may be the best choice for some commercial buildings in the area, despite the PNW precipitation. Keep in mind, though, that a properly constructed and installed flat roof may work well for your home and last for years. Flat roofs aren’t flat. They have a slight pitch to allow for water drainage, so if your roofer knows what they’re doing, your flat roof should drain water well without any pooling. Here’s a look at a couple of the advantages and disadvantages of flat roofs here in Portland.

Advantages of Flat Roofs

Flat roofs are great for industrial and commercial buildings because they allow for extra storage space and the installation of HVAC units. Flat roofs also provide residential structures with a modern look. Additionally, flat roofs offer residential structures with an additional outdoor living space for a patio or a garden. Flat roofs require less money up front when compared to pitched roofs.

Disadvantages of Flat Roofs

Flat roofs tend to have issues with water leakage due to their slight pitch. Flat roofs work best when they’re constructed with a seamless material such as PVC, TPO, and rubber membrane. While flat roofs tend to cost less upfront, their lifetime costs are more than pitched roof lifetime costs due to ongoing maintenance and potential issues that may arise, especially in high rainfall areas such as here in Portland.
Skillion roofs are often referred to as “lean-to” roofs. It’s a sloping roof attached to a taller wall, and can mainly be described as an angled flat roof. While skillion roofs are typically found on home additions, sheds, or porches, they’re also a way to achieve a modern look.

Advantages of Skillion Roofs

Due to their steep pitch, skillion roofs work well in high-precipitation areas. They’re easy to assemble and use less material than other types of roofs. They also look great, and they’re often used architecturally.

Disadvantages of Skillion Roofs

If the roof’s pitch is too steep, the ceilings may end up too low. Additionally, skillion roofs aren’t ideal in high-wind areas. Skillion roofs are also an excellent choice for solar panels.


Pitched roofs are the most common type of roof on homes here in Portland. They’re good-looking and traditional, giving your home a classic feel. However, there are multiple things to keep in mind when you decide on the type of roof you want.

Advantages of Pitched Roofs

As mentioned above, pitched roofs have that classic, homey feel to them. Additionally, pitched roofs drain water well, which is great for the rainy Pacific Northwest. The pitch of the roof also prevents water and other debris from hitting the home’s siding. Pitched roofs tend to be more durable than low-pitch or flat roofs, which decreases their lifetime cost due to lower maintenance costs.

Disadvantages of Pitched Roofs

Pitched roofs cost more at installation due to an increase in materials needed. Pitched roofs don’t work well for tall buildings or elaborate building plans, as pitched roofs don’t lend themselves well to some architectural designs.
The potential for water damage happens almost daily for those of us who reside in the Beaverton, Portland or Milwaukie areas. Generally the first place you will notice damage is on your ceiling as the paint may darken from mold or the plaster can bubble and flake off. But remember, these visible roof leaks may be hiding damage in the attic to the rafters, decking, and walls. Beside being a serious expense, the consequences to your health from mold and mildew issues can be a serious problem.
When it comes to roof leaks, the sooner you address the issue, the more likely you are to reduce the amount of damage and expense. In the Portland market due to the recent ice storm, getting a qualified roofing professional out to your home may take a few weeks. Be patient but put it on your list of things to do as summer nears.
We’ve saved the most obvious warning sign for last. Nothing lasts forever, and even the best roof will lose its protective abilities over time. The older your commercial roof gets, the more frequently you should have it inspected. At some point, it will need to be replaced.
