Should I Layer Shingles on My Roof?
Your current roof is likely past its prime if you frequently experience leaks, mold growth, or shingle loss. It’s time for you to consider getting a new roof. Many people mistakenly think the old roof must be completely removed, but that is only sometimes the case. Your roofing contractor might add more shingles over the first or second layer if the structure and shingles are in excellent condition. Many individuals find this a financially sensible option, but is it the best option? Below is what you need to know about adding extra shingle layers to your roof.
How Many Layers Of Shingles Can You Add To An Existing Roof?
Your community may have unique building regulations for your roof. Only two layers of roofing are permitted under some rules. You can add a third layer to those roofs that are steeper. Even the roofing materials you can employ for your home may be limited. Your roof may, in many cases, be covered with multiple layers of roofing materials. However, adding a second or third layer is sometimes a good idea.
You Need A Good Foundation
You need a strong foundation if you want to add more shingles. Sheathing or decking refers to the wood between your roof’s shingles and attic. When the shingles need to be replaced, those wooden components have likely been damaged in many cases. Any weak, rotting, or brittle decking must always be replaced. Over damaged wood, new shingles should never be installed.
Additional Layers Add Weight
The structure of your home may be strained by adding more shingles. About 2 tons will be required for one layer of roofing shingles and supplies. You can add up to 4 tons to your home if you add a third layer. Make sure the roof’s structure can support the extra weight before adding more shingles to it. You want to avoid putting your roof under additional stress that could lead to a collapse.
Most Shingles Need A Flat Surface
A flat surface must be covered with new shingles. Your top layer may appear lumpy because of uneven shingle textures and wrinkled felt underlayment. Old shingles should be covered with something other than new ones, especially if the first layer is curling or chipping.
