Roof It Right: Shingles, Tile, Metal, and More

While a new roof is a functional consideration, it’s also an opportunity to add grandeur, make things minimalist, or otherwise transform a home’s visual impact.

No matter what the roof type may be, it should get a yearly inspection. Are the shingles curling or buckling? Or brittle or cracked from sun damage? Are there missing or broken shingles? Is there rotting wood on the fascia and soffit? Any signs of moisture in the attic? Is the flashing around the vents and chimney still in good condition?

Many of these conditions, if caught early, can be fixed as a spot repair by the homeowner or a roofing company. But if the roof is nearing the end of its lifespan, that money might be better spent on a new roof.

Age alone is not a reason to replace a roof, but if the roof is over 15 years old, it’s time to give it a long, hard look, particularly if it is a flat roof or asphalt shingle. According to the International Association of Certified Home Inspectors, residential roofs can last from 20 years (average lifespan for three-tab asphalt shingles) to more than 100 years (clay/concrete tile with proper repair), depending on the type.
If you’re going to select a new roof, understand that it’s about more than just color or style. It’s about understanding the characteristics and benefits of each type. Here’s a breakdown.

A Is for Asphalt

The term “asphalt shingles” actually refers to three primary types: three-tab, laminated/architectural, and premium. The first is a single layer with three “tabs,” so that each shingle looks like three smaller shingles when laid out, for added visual interest. They come in a variety of colors and give a neat, clean look at a low price point, with a 20-year lifespan.

Laminated/architectural shingles add dimensionality and aesthetics, while premium or designer shingles can mimic the look of more expensive types such as shake, tile, or slate. Both of these types typically have 30-year or longer lifespans.

All asphalt shingles come in three levels of wind resistance—which is of particular interest to coastal folks with hurricane concerns—four classes of impact resistance (some insurance companies give discounts for Class 4), and are Class A (the highest level) fire-retardant. Algae-resistant shingles are also available from many manufacturers.

Tasteful Tiles

Clay tiles are one of the oldest roofing materials known to man and they add instant elegance to any home. They’re durable, lasting more than 100 years with proper care, and are low-maintenance, watertight, and fire-safe.

They’re also expensive, which is where concrete tiles come in. These typically cost less than clay and are equally watertight and fire-safe, but they either need to be sealed and resealed every few years or pressure-washed to remove mold growth. While they can also last more than 100 years, some roofers will say they have a more typical 50-year lifespan.

Concrete tiles, however, are available in more styles than clay: flat, low profile, and high profile (the iconic clay tile look). Both are more common in warm climates without severe freeze/thaw cycles, which can crack them. Both are highly resistant to impact cracks—remember, they’re common in hurricane zones such as Florida—but it can happen, so purchase some spares.

Weight is another consideration. Clay is 600 to 650 pounds per 100 square feet on average, with concrete a robust 950 to 1,200 pounds per 100 square feet.

Metal’s Mettle

Metal roofing is becoming much more popular, in large part due to its longevity (rated for 40 to over 80 years), low maintenance, impact resistance, Class-A fire rating, and the fact that it is extremely energy-efficient, reflecting the hot sun to reduce cooling costs.

However, they are expensive and can be noisy, particularly during a storm. Insulation or another underlayment can mitigate this.

There are three styles of metal roofs. The most economical is exposed fastener, where overlapping panels are secured to the roof deck or framing through the metal. The fasteners are typically the same color as the roof and are barely visible from below.

Standing seam, or concealed fastener, panels are either snapped together or mechanically seamed (utilizing clips that are locked together with a specialized hand tool). This allows the roof to expand and contract with changing temperatures, offer greater strength, and adds resistance to wind uplift. The third type is metal roof tiles that look like classic clay or colored concrete tile.

Another consideration is the roofing material. Galvanized steel is affordable and durable, but it can be heavy. Aluminum is lightweight, malleable, and offers color options, but it is less durable than steel. Zinc can last up to 100 years, is extremely low-maintenance, and is corrosion-resistant, but it can be hard to find and is costly. Copper adds instant history, is extremely durable, lighter than steel, and acquires a beautiful patina over time, but it is very expensive and can be dented.

The key to any roof choice is a combination of functionality, aesthetics and, of course, budget.

More Materials

While asphalt shingle, tile, and metal roofs are three top choices, there are additional options. And let’s not forget flat roofs.

Superior Slate

Slate tile roofs can last from 60 to an astounding 150 years, and are simply beautiful. Simulated, or composite, slate offers the glamor without the weight and cost, but expect to replace the roof in 35 years or less.

Timeless Timber

Wood shakes offer natural insulating properties to keep a home warm in the winter and cooler in the summer, while certain woods, such as cedar, boast oils that repel insects. Wood shingles are thinner than shakes for a more tailored appearance that works well on both roofs and exterior walls.

Flat Tops

Built-up roofing—traditional hot-tar and gravel over a waterproof material—is inexpensive and can last up to 30 years, while mid-price torch-down modified bitumen lasts 20 years. Costlier, but DIY-friendly, EPDM (ethylene propylene diene monomer) rubber lasts a good 15 to 25 years.
