Newport News Roofers: Article About Reroof Or Tear Off Old Roof
Deciding whether to remove an old roof or simply reroof over the existing shingles is a decision most homeowners will face at some point. One of the most common roofing systems currently used in the U.S. is asphalt shingles. These shingles often come with warranties that range from 15 to 30 years. However, many factors can play a role in how long these shingles will last.
While Newport News roofers can frequently install new shingles over an old roof, this practice usually reduces the life span of the new roof. The new shingles offer the longest life span and the best protection for a home when they are installed directly over a roof deck that has been covered with a new underlayment or waterproof barrier. Installing new shingles over an old roof will generally leave the new shingles slightly curved because they aren't being installed on a flat surface. This becomes an even bigger problem when the old shingles start to curl or tear.
Reroofing does offer some financial benefits to homeowners, however. For example, a big expense that is added to the installation of a new roof is the labor costs involved in having the old roofing materials removed. Additionally, once the old shingles and underlayment have been removed, there is the added cost for disposal of these items.

A homeowner who is looking for a budget friendly roofing option will often find that a reroofing project will save them a considerable amount of money.
While reroofing is a great way to save money in the short term, it is important that homeowners understand the long term costs. Not only will it shorten the life expectancy of the new roofing materials, but it can increase cooling costs as well. An extra layer of shingles tends to make a roof hotter in the summer, causing the home's air conditioning units to work harder. The harder an air conditioning system has to work, the more a homeowner will pay in utility bills.
A tear off will certainly add to the cost of a new roof, but it will also provide a more attractive finish. Reroofing, in general, tends to be a little uneven and the roof edges will have a thicker, less precise look. Additionally, when a home is reroofed, the contractor will not be able to visually inspect the roof deck. This means, if there are hidden problems, they can go undetected until the problem becomes so serious that water is leaking into the home.
