If you have ever seen a building that had two roof layers instead of just one, you have surely wondered whether that is a good idea or whether that would be a good solution for your roof, too. The answer depends on many things – here are some of those factors:

• The roofing material – while some lightweight, flexible roofing materials, such as asphalt shingles and metal panels, are suitable for being installed on top of an already existing roof layer, others, such as clay or cement tiles or wood are not suitable for such projects;
• The condition of the roofing structure – installing a second roof layer is a good idea only if the old roof surface can no longer be fixed with repairs, but the support structure of the roof is still strong and able to hold up the extra weight of the new layer.

The best way to figure out whether you can install a second layer of covering material on your roof is to hire a Highlands Ranch roofing professional to assess the condition of your existing roof and to make recommendations about the best way to proceed. Ask the roofer to provide a written evaluation report and to give you the recommendations in writing as well.
