Pros and Cons of Metal Roofing | Pacific West Roofing

If it’s time to replace the roof on your home and you’re considering buying metal roofing, it is important to do your research and weigh the pros and cons of metal versus other more conventional roofing materials, such as tile, wood and asphalt. Here, we consider the various benefits and downsides of metal roofing, such as aluminum, steel, and other metals.

It’s extremely durable. If you have your metal roof installed well and take care of it, it should last as long as the house and will easily survive wind storms, snow and rain water. Metal is also resistant to mildew, fire, insect infestation and rot.

Most metal roofs are noncombustible so they are rated with a Class A fire rating, which is the most resistant. However, if the metal roofing is installed over wood shingles, it will likely have a lower fire rating. Warranties will vary, but many companies will guarantee their metal roofing product to last between 20 to 50 years and paint finishes will often have a 30-year limited warranty.

It’s extremely lightweight. Metal roofing is lightweight, especially when compared to tile or other varieties. Most often, metal roofing runs from 100 to 150 pounds per square, compared to 750 to 1000 pounds per square for concrete tile. If you already have existing roof material installed, many times metal roofing can be applied directly on top of the other material without any tear off or additional structural support added.

It’s easy to install and will save energy in the long run. Metal roofing material comes in 12 to 36 inch panels or multiple-shingle sections. Because of this, it is quick and easy to install. Metal also reflects the sun’s heat, so it will often minimize the heat during the hottest part of the day. This means you will likely use your air conditioning less and ultimately, save more energy.

The disadvantages of metal roofing include:

It’s expensive. Metal roofing is pretty costly, with prices ranging from $150 to $600 per 100 square feet. This can be a big initial investment, but if you look at the durability of the material, it could save you on maintenance and roofing replacement.

It’s noisy. The Pacific Northwest gets significant amounts of rain every year, which means water will tap on a metal roof. A lot. For some people, this is a calming and soothing sound, but for others, not so much. Noise can be minimized by using materials that utilize structural barriers that reduce the drumming effect by applying them over insulation or solid plywood sheathing.

Accessibility. It is very difficult to walk or traverse on a roof in the wet weather or if there has been significant time for organic material to breed moss or algae creating an even slipperier surface to walk on. Maintaining a roof in the winter time to clean off storm debris or even to get your cat off the roof is often scary and challenging.

It dents easily. A metal roof can dent pretty easily, especially if something with significant weight and/or velocity hits it, such as a tree limb or large hailstone. Aluminum and copper roofing is more prone to denting than steel, simply because they are softer.

Before you decide on the type of roof to have on your home, be sure you consider your home’s style and the area you live in. For some, metal roofing makes perfect sense, while for other spaces, it may be better to go with other roofing materials.

How To Fix A Metal Roof | Pacific West Roofing

Although metal roofs are the most durable, there come times when some repair is needed. Whether your roof sustained damage by a storm, expansion/contraction or rust, these highly durable roofs do indeed sometimes need some TLC.02i33158

Before you set out to repair your roof, make sure you check your paperwork to see if it’s covered under warranty. The good news is that most metal roofs have a very extensive warranty, and you may not need to climb up there and do the work yourself. However, if your warranty doesn’t cover it, we’ve got some tips to make your time up there well spent.


First, take a look over your whole roof to locate any loose nails. If you have some, pull them all the way out and re-nail them back in.


If you find any holes or rust spots, you can fix them easily with these steps

  • Using a wire brush or steel wool, remove the rust completely
  • Use a metal primer on the area to prep for paint
  • Using a spray paint, spray the primed area. The color can be matched by going to any local auto parts store


You can use a urethane roof cement or even metal flashing to seal and leaks you find. However, make sure you smooth it over the leak area to keep from trapping water. Also remember, urethane roof cement and metal flashing will ultimately deteriorate and need to be replaced in the future.


Using urethane-roofing cement, make sure to reseal any areas you find with holes or openings.


To replace the metal flashing on a metal roof, call a roofing contractor to complete this effort.

Are Metal Roofs Energy Efficient? | Pacific West Roofing

Keep this in mind – your roof is the part of your house that gets the most direct sunlight, if it isn’t shaded. If you want to cut down utility costs, it’s critical to have one that’s energy efficient.

When people are choosing a new roof, the main concern is how it looks. Of course that’s important. But don’t you want one that can save you money, too?

Metal roofs can do that. We’ll explain.


Here’s the truth: metal roofs have a high upfront cost, higher than traditional asphalt. Looking past that though, you are buying something with far lasting value. A metal roof lasts anywhere between 40-70 years. In comparison, an asphalt shingle roof lasts about 20 years. Metal roofs are also low maintenance, which factors into upfront costs.

Now, about those bills. The Metal Roofing Alliance reports a home with a metal roof can save up to 40% on their summer cooling energy costs. See, a metal roof can be coated to make it reflective. What that means is it’ll reflect sunlight, rather than emit it as heat into your attic.

High energy efficiency rating for this home

(note: several metal roofing materials, such as steel, come pre-coated. When buying, you can choose between different coatings, as each one has different reflective properties. Make sure you inquire about the “emissivity” of it – i.e., how it will contribute to energy efficiency).

Metal roofs are also eco-friendly. Not only are they comprised of 30 to 60 percent recycled materials, but they can be recycled once you’re through using them (asphalt shingles are just now becoming more recyclable).

And, since looks are important, they do give you some options. Metal roofing can come in panel or shingle form, as well as different colors. For overall aesthetic, they go well with most styles of modern or rustic architecture.

Remember, though, that when you are choosing a more energy efficient roof, you have to pay attention to the whole assembly. That means the decking, insulation, etc. You will want an experienced roofer to make sure the whole system insulates well.

Pacific West Roofing uses the most eco-friendly and long-lasting materials for installing new roofs. We are backed by CertainTeed’s highest honor contractor warranty program. Start the conversation on how to make your roof, and your home, as energy efficient as possible.
