Then again, if you plan to move in a couple of years, you probably won’t get a reasonable return on your investment unless your future buyer recognizes the long-term value of the roof.Īdd up all materials and labor and divide this sum by the number of years the roofing is expected to last to estimate your roof’s cost per year. Wood shingles and shakes – $10,000 to $20,000īecause of the material’s long-term durability, the trick is that you ultimately save the difference (and more) if you stay in the house for a long time and you save on seasonal maintenance.Asphalt-fiberglass shingles – $4000 to $7000.“Many metal roofing systems have been tested and proven to withstand winds in excess of 140 miles an hour, which is the equivalent to an F2 tornado and provide protection against impact damage from debris.” say’s Todd Miller, Vice Chairman of the Metal Roofing Alliance.įor the sake of comparison, here is a list of typical price ranges for metal roofing and other common roofing materials for an average size home: Also, asphalt roofs require replacement every 15 to 20 years, so nearly 20 billion pounds of old asphalt shingles are dumped in US landfills every year, according to the Environmental Protection Agency.Ī Metal Roof Stands Up to Tornadoes & Hurricanes Manufacturing asphalt uses petroleum and fossil fuels.
Don Vandervort, HomeTips © 1997 to 2023 | HomeTips Steel Roofing Is Environmentally Friendly Dark surfaces warm in the sun to aid in quickly melting snow. The panels are applied over dense foam insulation to maintain high R-values.
Metal roofing is great in snow country because it is fire resistant, lightweight, and excellent at shedding snow. In addition, dark tones of metal roofing quickly warm to the sun, encouraging snow melt. Metal roofing is practically impervious to rain and snow because of the way the panels interlock and because the surfaces are hard and slippery. In addition, many systems utilize a dead-air space between the metal surface and roof deck beneath it to minimize heat transfer, increasing energy efficiency. Regarding the insulation value of metal roofing in both heat and cold: Though the material itself is low in insulation R-value, metal roofing can be applied over foam insulation that has very high R-values. You can get a 10% tax credit up to $500 (not including labor). In fact, federal rebates are offered for metal roofing that has appropriate pigmented coatings that meet EnergyStar requirements. This reflective characteristic means you save energy needed for air conditioning during the day. Metal reflects radiant heat from the sun, minimizing midday heat gain. (See notes under “Metal Roofing Drawbacks” regarding problems in the event of a house fire.) Most metal roofs applied over a combustible material such as wood shingles have a lower, Class C rating for this reason. Just be aware that part of a roof’s overall classification depends on materials beneath the surface that could ignite in intense heat, too.
But leaving the old roof in place also has advantages. Of course, tearing off the old roof so you can start with flat, sound sheathing certainly gives you a much cleaner starting point. Check local codes and the manufacturer’s specifications before doing this.

In fact, if you’re building a new house or a new addition, you can often downsize or reduce the number of roof support members because of metal roofing’s light weight.Ĭan Metal Roofing Go Over Existing Shingles?Īs long as the existing roof surface and the decking beneath it are sound, flat, and free of rot, metal roofing can usually be applied over the top of one old layer of asphalt shingles.
