Bergen County Roofing: Article About Reroofing Versus A Complete Replacement
When it's time for a new roof, homeowners have a number of important decisions to make. They not only have to consider what type of roof they want installed, but they must also keep their budget in mind. While even a common asphalt shingle roof can be a major expense, there are some roofing materials that might be cost prohibitive. For example, Spanish tile is always attractive and can be used with a wide variety of architectural styles, but these tiles are costly to both install and repair. Another consideration is whether you'll have all of the old roofing materials removed or simply have your Bergen County roofing contractor install a new roof over your current roofing system.
If you only need a short-term roofing solution, you might want to consider reroofing. This is typically a more affordable option because the old roofing materials are not removed. Your roofing contractor will install the new roof directly on top of your existing shingles. Of course, it's important to make sure that your current roof is in good condition and that the roof deck is able to handle this extra load.

A roof with numerous missing shingles or decking that is sagging or in need of repair will likely not make a good candidate for reroofing. Additionally, because of the extra load put on the structure of your roof, building codes will typically not allow a home to be reroofed if there are already two layers of roofing materials installed.
A tear-off is a great option, especially if you want a long-lasting roof. The removal of the old roofing materials will certainly add to the overall cost of your new roof, but it will be money well spent. When the old roofing materials are stripped off the roof deck, your contractor will be able to quickly see any signs of damage. Problems with the deck or structure of your roof can be dealt with prior to the installation of the new material.
A cleared roof deck also allows for the installation of a new underlayment. This can help protect your new roof from water leaks and damage. Additionally, because the new shingles will be installed on a clean, flat surface, they'll be able to lie flat as the manufacturer intended. Reroofing often results in the new shingles molding to the old roof, which ultimately reduces the shingles' longevity. With a good installation on a clear deck, your new shingles will often be able to provide 25 to 30 years or more of reliable protection.
