An overlap is a viable option if existing roofing materials have not yet overlapped. Home Reference, net points out that, on average, you can expect the overlap to last fifteen or sixteen years. Best case scenario is that your roof is in excellent condition (aside from surface damage) and is relatively new. If this is the case, the roof covering should last about 16 years.
While this doesn't have as long a lifespan as a new roof, at least it's in the stadium. Most roofs last between 15 and 30 years, and factors such as bad weather can significantly reduce their lifespan either way. However, in many cases, homeowners aren't dealing with this best-case scenario. If the repair is being carried out due to age or extensive damage, you may be redoing that work sooner than you think.
Longer lifespan: A new, properly installed tile roof can last 20 to 30 years, which means it could last a decade or more. A traditional asphalt roof has a lifespan of 12 to 20 years. While there are more high-end products that can last longer, this is the average. When the roofers tear off the entire roof, they have the opportunity to examine the terrace on which all those tiles sit.
During this process, they can evaluate your platform for potential problems, such as leaks or rotting. With overlapping, that process doesn't happen and can cause problems in the future. A roof covering is the process of adding a layer of shingles and waterproofing over an existing roof. It is most commonly used as a way to extend the life of a roof and save money by not paying the costs of removing and removing the old roof.

The best scenario for an overlap is a solid cover; no previous or existing leaks; and a roof without side walls where flashings are needed to attach the roofing material to the exterior walls of the house. But if you overlap it, you cannot install a barrier against ice and water leaks, since it has to adhere directly to the wooden platform. So, if you have an ice dam in winter, you could easily travel under the deck and leak under the old roof.
The second layer is also more difficult to install correctly compared to new shingles. The flashing around roof penetrations and side walls can. In addition, depending on the size of your roof, you have added several tons of weight, which could pose a big problem if there is significant snow buildup. If there is any advantage to overlapping a roof, it is to save a little money.
But because of the amount of prep work involved in properly overlapping a roof, any savings are usually modest, perhaps 25 percent compared to a new roof. Shingles may not last as long, so the job may end up costing you more in the long run. Savings simply don't guarantee compromise on quality and potential risks. That said, overlapping asphalt shingles with a metal roof could be an option, provided there is no underlying damage.
Metal roofs offer energy savings, but cost more upfront than traditional asphalt shingles. They also last longer and resist bad weather better than roof tiles. No matter what type of roof you choose, be sure to tell your roofer to fix any underlying problems you have before installing any new roofs. The bottom line is that your roof is arguably the most important component of your home.
After all, it protects everything underneath, so it's not an area where you want to cut shortcuts. Weighing the modest savings against the possible uneven appearance, reduced life expectancy, and the risk of future leaks, I would advise against coating with new shingles. Find a quality roofing contractor who can assess the condition of your roof and get the job done right. Overlap the ceilings, analyze the difference between them and determine what can make one option more suitable for your home than the other.
Werner Roofing is proud to offer free roof inspections for every customer, so you can be sure of the condition of your roof. Those damaged shingles provide a poor foundation for new shingles, so your new roof could be noticeably defective, no matter how skilled your roofer is. Since metal is so light, you don't run as much of a risk of putting too big a load on your roof system. If prospective homeowners learn that you just added a new roof, they can expect to pay for the luxury of not replacing it themselves.
Your roofer won't need to rent a dumpster and deal with debris removal regulations, so you'll save on costs there, too. Since an overlap roof is made up of two layers of shingles, it traps much more heat and is prone to problems that can arise between the two layers. A roof covering involves placing new shingles and other materials directly on top of the existing roof, replacing the entire surface, but leaving the rest of the roof structure intact. Because you're paying more than the cost of new shingles when you factor in the cost of a new roof, the cost of replacing your roof with the starting method is higher than other methods.
Complete roof replacement will involve tearing off shingles and other structures and installing new materials. An overlap roof isn't the best option, and it's certainly not the right choice for everyone, but there are some situations where it can make sense. The finished roof covering will only look as good as the old one; drops and curls on the shingles will inform what the new shingles look like. During a takeoff, your roofer will have the opportunity to thoroughly examine all parts of your roof and make repairs to avoid any problems that develop before they cause serious damage.
Lower quality: For a roof to be as reliable as a tear, your current roof would need to be in near optimal condition. . .
