What type of roof do i have?

Owning and maintaining a home comes with countless tasks, a never-ending list of “to-dos,” and frequent trips to your local hardware store. Knowing and understanding the basics of your home’s big-ticket items helps you maintain them. Your roof protects your home. In general, a roof needs to be replaced every 15-20 years, and with good maintenance, it will last that long. Even roofs that are “maintenance free” still need to be observed and cared for in order to get the maximum time out of your roof. Understand what type of roof covers your home before you decide what roofing material to replace it with.

Knowing what type of roof you have is the first step at maintaining it. When you know and understand it, you have a better chance at knowing what it needs and who to call if there’s a problem. Orca Roofing specializes in high-quality roofing for your home and offers a number of different types of roofing materials. Depending on what type of roof you have, we have the right material for your roof job. 

The first step in determining what type of roof you have is relatively simple. It all depends on the pitch. If you have a sloped roof you most likely have a composition, asphalt-based roof, slate tiles, cedar shingles, a metal roof or even innovative, recyclable composite roof tiles. If your roof is flat or very low-sloping, you most likely have one of a couple synthetic materials: TPO rubber, EPDM rubber, or PVC roofing. Determining if your roof is sloped at 3/12+ or flat (less than a 3/12 pitch) makes an important distinction between materials.

Composition Roofing

If your home has a sloped, pitched roof, it could either have a composition, slate or cedar-shingled roof. Most homes in the rainy Pacific Northwest don’t have terra cotta tiled roofs, but there are exceptions. Many homes have composition roofing, but not all composition roofing materials are created equal. Most roofing companies sell a “good, better, best” option, but Orca Roofing only sells and recommends the best options from Owens Corning. Composition roofing usually has a rough texture, lay flat, and come in dark colors. They are made of asphalt and other materials, and the higher the quality of the material, the longer the roof will last. Architectural composition shingles overlap in a varied, textured way imitating a natural cedar shingle look. 

Cedar Shingles

Cedar shingles are (obviously) made of cedar. On a roof they have natural visual and tactile texture. They are still a popular type of roof, but Orca Roofing doesn’t install cedar roofs for a couple different reasons. Old-growth cedar makes the best roof shingles because the wood is dense and strong. Because companies are better stewards of the earth’s natural resources, there is farmed cedar, which is better than cutting down old-growth wood, but doesn’t maintain the quality needed for a high-quality roof. Farm-grown cedar shingles are thinner, easier to break, and because of the lack of density can swell and contract on a more extreme scale. In short, a farm-raised cedar shingle roof won’t last as long as a composition roof. 

Slate Shingles

Slate is a gorgeous, but costly, material not frequently used on roofs anymore. Old, stately French manors or castles had beautiful slate roofs, but spotting a slate roof in the Seattle area would be a rare showstopper. Slate is a natural material, a bluish gray-toned stone, cut flat. It creates a natural barrier against the weather, but it also adds sheer weight to the roof load. Homes with a slate roof tend to need hefty reinforcement to withstand the weight of a slate roof. 


Thermoplastic polyolefin (TPO) roofing is installed on flat roofs. It is a single-ply, synthetic water-proof membrane which is both energy efficient and heat reflective. The rubber and filler blends make it a flexible and durable roofing material. The seams are heat sealed with a seam welder. TPO roofing is preferred over PVC and EPDM, both flat-roof roofing materials, because it is more energy-efficient and doesn’t contain environmentally harmful chemicals like chlorine. We like TPO roofing for flat roofs because of its flexibility. It is tear and puncture resistant, and is able to flex if the building moves or settles. 

Composite Roof Tiles

Composite Roof Tiles, like Brava Roof Tiles, are a newer roofing material on the market. You probably don’t have this type of roofing material on your roof (yet), but these roof tiles could be a great option for your next roof replacement. These roof tiles are made from recycled materials, and are fully recyclable. They come in a variety of finishes and colors, they are light weight, unbreakable, don’t fade over time, and are virtually maintenance-free. For a new, innovative roofing material, Orca Roofing is the exclusive installer of Brava Roof Tiles in the Pacific Northwest. 

Metal Roofing

Metal roofs are incredibly versatile, and can withstand extreme temperatures, both hot and cold. They generally come in corrugated, standing seam and tiles, and they last for a very long time if well maintained. Keeping an eye out for leaks or congregating debris can ensure a longer life for your metal roof. Orca Roofing installs locally owned Nu-Ray Metals roofing.

Roofing upgrades not only contribute to the aesthetic appeal of your home but can also make it more energy-efficient. By investing in energy-efficient roofing materials and insulation, you can reduce heat transfer and minimize energy consumption. This results in lower utility bills and a more comfortable living environment. Potential buyers recognize the value of energy-efficient homes and are willing to pay a premium for properties with such upgrades.

3. Extended Lifespan and Durability

Roofing upgrades involve using high-quality materials and employing skilled craftsmanship. This ensures that your roof not only looks great but also provides long-lasting protection for your home. Upgraded roofs are designed to withstand the elements, including harsh weather conditions, which can significantly extend the lifespan of your roof. A durable roof adds value to your property by offering peace of mind to potential buyers, knowing they won’t have to worry about costly repairs or replacements in the near future.

4. Improved Home Insurability

Insurance companies often consider the condition and quality of your roof when determining the insurability and premiums of your property. By upgrading your roof, you demonstrate your commitment to maintaining a well-protected and safe home. This can lead to lower insurance premiums and increased coverage options, which are attractive features for potential buyers and can ultimately raise the value of your property.

5. Increased Resale Value

Investing in roofing upgrades is an investment in the overall value of your property. When it comes time to sell your home, an upgraded roof becomes a strong selling point. Potential buyers are willing to pay more for a home with a new or recently upgraded roof because they understand the long-term benefits and savings it provides. A well-maintained and upgraded roof showcases your dedication to maintaining your property, making it more appealing to buyers and potentially leading to a higher resale value.
