If your roof is in rough shape and you are looking to install a new one, you may be considering simply overlaying a new roof on top of the old one. However, there is another option available as well. You can remove the existing roof and then install the new one. While many people do not realize it, this second option may be the superior choice when replacing a roof. Get to know some of the reasons that you should remove instead of overlay your roof. Then, you can talk to your roofing contractor about what you would like to do regarding your roof replacement.
Overlaying Adds Extra Weight to Your Roof
One of the major disadvantages of overlaying your roof is that adding another layer of shingles on top of the existing roofing will add weight to your roof. This extra weight adds pressure on the structure of your house, and too much pressure can cause serious damage to that structure. If your house is older this is of particular concern as the home may not be built to safely hold that much weight. Additionally, your home could already have an overlay roof that you do not know about which could further exacerbate these structural issues.
Overlaying Does Not Last as Long
If you want to get the full lifespan potential of the new shingles out of your new roof, you do not want to do an overlay. Overlay roofing, while quick and convenient also means that your roof will not have the best longevity. The multiple layers of shingles on your roof will trap heat between those layers. The heat trapped there will cause quicker wear on the shingles, including issues with curling. Curled shingles are less effective at keeping out moisture and otherwise protecting your home. It is easy to get caught up in the fact that overlaying saves money in the short-run and forget that you will just have to replace your roof again in the near future if you go that route.
Overlaying Doesn't Allow You to See Underlying Problems
One of the biggest advantages of fully removing a roof before you replace it is being able to see what (if any) damage lies underneath the roofing that you are replacing. Chances are, if your current roof is in poor shape, you will have at least some damage to the underlayment of your roof. Removing the shingles will allow your roofing contractor to see that damage and address it before laying the new shingles. This will better protect your home and prevent major issues from occurring in the near future.
Knowing these reasons that you should remove instead of overlay your roof, you can be sure you talk to a company like Villatoro & M. Construction Inc. about roof removal.Share
