Roofing issues can be complicated— that’s why professionals should be the ones tapped to address them. This way, homeowners can also determine and understand the resolutions needed to be done. Today, your roofing services provider will mainly delve into why you should not cover your existing damaged roof. 

Nail Over Your Old Roof
  • It adds unnecessary weight to your roof. Putting another layer of heavy shingles on your roof just adds weight to your system, which reduces its structural strength. New shingles will absorb more heat, and it also wears down the new shingles than if they were installed on the wood sheathing.
  • It fails in eliminating leaks. Roofing experts and siding contractors say a roof overlay cannot address leaks. Moreover, due to its current storm damage, water will easily seep between the layers and materialize in other spots making patching very challenging.
  • It is not recommended. Professional contractors usually don’t practice go-overs because they know they won’t last as long as a complete roof replacement. Hence, if you’re offered to consider a re-cover, trust that it probably won’t work. Furthermore, nailing the new roof board onto the old roof will void most manufacturers’ warranties as the old roof must be removed before installation.
  • It will eventually require a replacement. A roof that has been re-roofed is more susceptible to storm blow-off than a newly replaced one. As stated, you’re more likely to need your roof replaced in a few years if you opt to choose this option which doubles the labor and costs.
