If you are thinking about adding a second layer of shingles to your roof, be sure to weigh all the pros and cons first! There are some advantages however, it’s best to learn all the details first. Here are some tips to help you decide if it’s right for your home roof replacement in Plymouth Michigan.
What could happen if you add a second layer of shingles to your roofing in Plymouth Michigan
If you re-roof over an existing roof, there’s a chance that you’ll void the warranty on your new shingles. Some manufacturers require that their shingles be installed on a clean, smooth surface for the warranty to be valid. If you re-roof over your old shingles, the new shingles may not lie flat and could eventually develop problems.
You could also have problems with drainage if you add a second layer of shingles. The weight of the new shingles could cause your gutters and downspouts to sag or even collapse. And if the new shingles are darker than the old ones, they could absorb more heat from the sun, making your attic even hotter in the summer.
Finally, re-roofing with a second layer of shingles will add weight to your roof. This could put stress on your roof framing and cause it to sag over time. If you live in an area with high winds, this could also make your roof more likely to blow off in a severe storm.
So, while there are some advantages to re-roofing with a second layer of shingles, there are also some significant drawbacks. Weigh all the pros and cons before making a decision and be sure to talk to a qualified roofing contractor in Plymouth Michigan to get the best advice for your home.
Save Money with a Re-Roof on Your Home
If you’re like most people, you want to save money on your roof replacement project. With proper research and planning, you can find a great roofing replacement for your home that can be less expensive while still protecting your home. When you get a new roof installed typically the old roofing materials are removed which can cause labor costs and debris removal costs go higher. When you get an additional layer of shingles installed on your home you can eliminate some of the costs associated with removing the old roof which can save money.
Will Your Roof Support More Layers?
One of the biggest problems with getting additional layers of shingles installed on your home is the weight of the roofing materials. Most homes are simply not structurally sound enough to handle any more than 2 layers of shingles total. Some may not even support that. Depending on the type of shingles you have installed can also affect how many layers can be added. For instance, three tab shingles are single layer shingles so adding an additional layer will give you two total layers of shingle material. However, some architectural shingles have multiple layers of shingles which when has an additional layer can be up to four layers of shingle material on your roof which can be very heavy. It’s best to talk with your roofing contractor about the roof replacement for your home and whether it is a good idea for your home structurally.
