Comparing Roof Shingles

Roof shingles can simply keep the rain out, or they can be an architectural feature that enhances curb appeal. Given today's choices, you can do both.

There are a few types of roofing that we won't discuss here. That's because I don't believe anyone in their right mind would ever use those materials. All those that are good options are listed.

Most people have an existing roof which needs replacing, and only explore using the same material for the replacement. With the various roof shingles available today, you can think outside the box.

In many towns, local ordinances will restrict the type of roof shingles you may use. Some have reasons to do with the overall consistent look of the community. Others are worried about health and safety issues. Look into this before you buy anything.

Composition (asphalt) Shingles

This is the most common roofing material used for homes - by far. Shingles come with one of 2 warranties: either 20 years, or 30 years. They could be the standard 3-tab style, or the architectural designer styles which replicate other materials. Go for the 30 year warranty. The difference in price is insignificant.

ADVANTAGES - these are relatively inexpensive; they are durable; they come in many colors and designs; they are easy to repair; and they are fire resistant.

DISADVANTAGES- a relatively short life span; subject to mildew & moss; environmentally unfriendly.

Shingles are cut uniformly and are smooth. Shakes are irregular and rough. This type of roof is often used when a home has a landmark or historic designation.

ADVANTAGES - has a natural look and will weather to a greyish hue; blends with the surrounding environment; easy to repair; will last 30 to 50 years if properly maintained.

DISADVANTAGES - expensive; high maintenance; prone to mold and mildew; will split and could rot; not good in a fire.

Metal Roof (tin, copper, steel or aluminum)

Also used on historic houses (more than wood). Also found on bungalows or cottages. They seem to be making a comeback, but this wouldn't be my first choice. For one thing, they are noisy when it rains. For another, they get very hot in the summer sun.

I've seen metal roofs used to accent parts of a house - like over a bay window, or on a rotunda. At one point, I thought they attracted lightning. Then I found out that metal roofs actually dissipate a lightning strike.

ADVANTAGES - available in styles that look like cedar shingles, slate or the more traditional standing seam; comes in many colors; light weight and durable; a life span of more than 50 years; low maintenance; can be installed over an existing roof; and environmentally friendly.

DISADVANTAGES- difficult to install (means costly); not cheap; noisy in rainy weather.

Tile Roof (clay or concrete)

Often used on Mediterranean, Italian, Spanish, or Mission style homes. Seen more in Texas and California than New England.

ADVANTAGES- non-combustible; many colors and styles to choose from; attractive; low maintenance; very durable.

DISADVANTAGES- expensive; heavy - the roof might need to be reinforced; installation and repairs are difficult; breakable when someone walks on the roof.

Slate

Use on traditional homes like Colonials, French and Italian, as well as homes of Beaux Art design.

ADVANTAGES - beautiful and distinctive; fireproof; long life span; low maintenance.

DISADVANTAGES - expensive; requires professional installation; heavy; fragile when walked upon.

Regardless of the roof shingles you choose, always repair any structural problems before installing a new roof. Any trouble with damaged sheathing or trusses, or poor drainage, must be dealt with prior to installation of the new roof.

If you live in a humid climate, roofing treated with zinc or copper particles will keep the mold and mildew to a minimum.
