Asphalt or Metal? Picking a Material for Your New Roof
Chelsea O'Donnell
Installing a new roof is one of the biggest remodeling decisions that any homeowner has to make. Finding the right contractor, negotiating the right price, and deciding on the color and style are just a few of the options to navigate.
In the past, one thing homeowners often didn’t have to think about was the material, as asphalt roofs have been the most popular choice in our area for their cost effectiveness, aesthetic and durability. But this past weekend on a visit to New Hampshire, I noticed the number of homes that are clad in metal is on the rise. While metal roofs are more popular in areas of the country with more extreme weather conditions, it’s always good to know about the different options available. So let’s take a deeper dive into the pros and cons of asphalt and metal roofs to help you make the best decision for your home.
The Asphalt Roof
Asphalt is the most popular choice with homeowners for a variety of reasons, but the single most important factor is almost always the price. The average cost to purchase the materials for an asphalt roof is nearly one-third of the cost of a metal roof. That cost differentiation gives asphalt the leg up almost every time. In addition to being the more cost effective option of the two choices, there is a lot to love about asphalt. Individual shingles give a homeowner lots of color and design choices, and they are faster to install than a metal roof, often taking just a few days of labor. While most asphalt roofs come with a 30-year warranty, they are easy to repair if damaged, and a small section can be replaced without having to get a whole new roof. The material also performs exceptionally well in the rain, heat, sleet, and snow.
Of course, there are a few negative aspects of asphalt roofing that homeowners should be aware of. If you’re installing a new asphalt roof, I always recommend removing the old roof before installing new material, which does add to the labor cost. Another negative factor is the chance that mold, mildew, and algae will grow if a roof is shaded and stays damp for long periods of time. Also, while our Connecticut weather isn’t as severe as other parts of the country, very high winds can loosen shingles if they aren’t installed properly.
The Metal Roof
Even though they aren’t as common in our area, metal roofs have some very attractive qualities that make them worth considering. Firstly, the material is lighter than traditional asphalt roofs, and the metal sheets can often be installed right over regular asphalt as long as it doesn’t have water damage or rotten plywood underneath. Metal roofs also last longer than asphalt roofs, and maintenance is minimal. Mold and mildew cannot grow on metal so if you live in a damp area with lots of shade, this is worth considering. Another plus is that metal roofs are energy efficient all year round, helping to keep the house cooler in the summer and warmer in the winter. Plus they perform very well in areas with very high-level snowfall.
Of course, there are a few cons that homeowners should be aware of, and the biggest one is cost. While metal roofs do last longer, the upfront cost can be three times as much as an asphalt roof. Additionally, if a metal roof needs to be repaired, that will also cost more as metal roofs are made in sheets and need to be replaced in that way. From an aesthetic perspective, metal roofs do come in different colors, but there aren't many more options in terms of design and aesthetic. Finally, it’s important to know that without the proper plywood installation and insulation, metal roofs can be noisy, which might not be a con for people who love the sound of rain storms.
No matter which material you use, it’s important to do your research to find the best product for your individual home. The right roof with the right contractor at the right price will ensure that you live comfortably with peace of mind for many years to come.
