Asphalt or Metal? Picking a Material for Your New Roof

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.

Say So Long to Solar Panels with This Latest Invention

You’re probably familiar with Tesla, the luxury car company that made a name for itself by introducing solar energy cars to the market. Now, Tesla CEO Elon Musk has turned his attention to a different use for solar energy by announcing the launch of solar shingles which officially went on sale last week. So if you’ve been considering solar energy for your home but don’t like the look of massive panels stuck to your roof, this game changer might just be the solution you’re looking for.

If you know anything about Tesla cars, you know that they aren’t cheap and neither is the new solar roof. Installation on an average 1,800 square foot house will set you back more than $68,000, but Tesla estimates that over the roof’s 30-year life span, the solar shingles will generate over $88,000 in energy production. The 30% federal tax credit, known as the Solar Investment Tax Credit, will be available for the product and can be applied to the cost of the solar portion of the roof as well as the cost of the required Powerwall battery. Based on that percentage for this example, you’d be looking at a tax credit of $20,000 which, according to the company, brings you to around $40,000 in net earnings over the 30 year period.

The roof configuration is made up of both solar and non-solar panels, with Tesla recommending a 60-70% ratio of solar to non-solar units depending on the individual home. Unlike those unsightly solar panels we’ve come to accept as the best way to harness energy from the sun, solar roofs look very similar to a regular roof with both textured and smooth panel options which are approximately the same size as a regular roof shingle. Units designed to mimic the look of slate and Tuscan style terra cotta will both be launched in 2018.

But with our brutal seasons, will these new glass panels really be able to stand up to the weather? Tesla says yes and has given the product an infinity warranty based on the lifetime of the house. The panels also get the highest rating for wind, hail, and fire damage.

So when might you be able to get your hands on a solar roof? Tesla says they’ll begin installations in California starting in June, with a nationwide rollout planned to follow. While we aren’t sure when the product will be available yet in this area, I’m interested to know if it’s something homeowners here would want to know more about. Does a solar roof pique your curiosity? I’d love to know more. Message me on Facebook to tell me what you think at www.facebook.com/odonnellbros.

Get Rid of That Funky Roof Mold

Have patterns of strange, streaky stains appeared on your roof this spring? My phone rings off the hook for roof cleanings this time of year, and as I drive around town, I see so many houses decorated with unsightly roof residue, which frequently emerges during the April rainy season. But what are the stains, why have they suddenly popped up, and what can you do to get rid of it? They are all good questions, so let’s get you some answers.

Stains on the roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until they have enough moisture, heat, and humidity to grow and spread. The manifestation of an algae problem is those black streaks that you see. Now don’t be too alarmed, algae isn’t necessarily going to ruin your roof immediately, but it does affect the curb appeal of your home and the problem could end up damaging and pulling up your shingles if not dealt with for a long period of time.

An interesting fact is that copper, zinc, and lead are toxic to algae, and many newer roof shingles contain copper granules, which act as a barrier against any mold growth. Homes with older roofs won’t benefit from this technology, but it explains why you won’t see algae where metal flashing has been installed. If you’re susceptible to algae and in the market for a new roof, be sure to inquire about this type of shingle.

So now that we know what it is, how do we get rid of it? The easiest way to rid your roof of algae is a good cleaning solution, which can be picked up at the hardware store, applied using a pump sprayer and rinsed with the garden hose. One tip is to give any plants below the roof a good drink of water beforehand so they don’t absorb the solution. If you’re not comfortable on a ladder, call a professional to help you complete this task. A clean roof isn’t worth a trip to the hospital, and a local area home improvement specialist will be able to complete the job in just a few hours.

Once the roof has been cleaned, you might want to do something to prevent the mold from coming back again. As I mentioned, copper, zinc and lead-coated sheet metal are toxic to algae, so installing a strip of flashing will help stop that nasty fungus in its tracks. Choose a strip that’s at least six inches wide, and have it installed at the roof peak to ensure that the metal molecules wash down with the rain and protect the roof from mold build up.
