Union’s steel roofing panels weigh 50% to 65% less per square foot than most asphalt roofing shingles. Installing metal roofing over your existing asphalt shingle roof eliminates landfill waste and saves labor costs for removing the old asphalt roof shingles. Most roof types simply weigh too much to be installed over top of one another without adding additional structural support to the roof. Roofs are designed to support a predetermined amount of weight and the installation of subsequent layers of heavy roofing materials such as asphalt roofing shingles can cause structural damage. In these cases, removing the old asphalt roofing shingles is usually recommended, but this creates a large amount of landfill waste. In fact, asphalt roofing shingles make up over 3% of all municipal solid waste, or 6.8 million tons annually. Installing metal roofing over shingles can help solve these issues. Because metal roofs are so light yet so strong, metal roofing panels can typically be easily installed over your existing asphalt roof shingles without the need to add structural reinforcement. The old asphalt roof shingles under the metal roof simply serve as an extra layer of insulation and water protection and pose no problems to the new metal roof. Of course, each metal roofing over shingles installation is different, so consult your licensed metal roofing contractor to confirm if your roof is suitable for a metal roofing over shingles installation.

The vast majority of installations of the metal roofing systems produced by my company are over existing shingles. The low weight of metal roofing is one thing that encourages this. Steel shingles weigh about 1/4 what asphalt shingles weigh and aluminum shingles weigh about 1/8 what standard shingles weigh. I would say that in most cases, less weight is being added to the home by the new metal roof than what the current shingles have lost due to granule wear and oil evaporation. In other words, the total roof weight was probably greater when the last layer of shingles was installed than it will be when the metal roof is completed.

Taking advice from a roofing CON-tractor is like being in a henhouse and asking a fox for advice. Use a little common sense in any project and you will be fine. The more you research a project beforehand the better off you will be in making the right choice when it comes time to hire someone to do the job. First off the weight of metal panels is not much so this would not be a concern. A metal roof should not leak at anytime and the only problem might be condensation, which is no big deal. If you’re worried about heat buildup under the metal roof then make sure your metal roof is light in color to reflect the sunlight. The lighter the better with white being the best. If you are worried about the condition of your roof under the shingles then go look at the attic side of the roof. If the wood is in good shape then why remove the shingles to see it? Before doing business with anyone make sure you check his references, background and be careful that he is not trying to charge you for more work than is necessary. So to answer this question I’ll use another question. Why remove shingles when installing a metal roof when there is no reason to do so?
