Residential Roofing, Roofing Repair

Generally speaking, new roofing can be installed directly over old roofing. However, being able to install new roofing over old roofing depends on multiple factors, such as how old the roofing is, the condition of the old roofing, and the combined weights of the old and new roofing materials.

Tips for installing roofing over your old roofcan a new roof be installed on top of my old roof

Before moving on to the pros and cons of having new roofing installed, it’s important that you know the basics of re-roofing. First of all, You can only properly relay roofing on top of an old roof if they are the same material. For example, if you want to install adobe roofing, and currently have asphalt roofing, you’ll first need to have your asphalt shingles removed. Your roofing will basically have to undergo a traditional roofing replacement. Essentially, re-roofing works only for asphalt shingles being replaced by asphalt shingles.

Advantages of re-roofing

Costs less than removing your entire roof

As you’d expect, re-roofing will require less labor than removing and replacing an entire roof. Tearing down a roof can cost around $1,000 in and of itself. By re-roofing your home, you will be saving on labor and material costs, as the roofing will not need to be refelted.

Long-lasting warranty

Generally speaking, the new roofing shingles should have the same warranty as your old shingles. All you’ll need is proof that your roofing will be installed by a professional roofing contractor.

Looks as good as new

While re-roofing is a more inexpensive option, you’re not skimping on quality. Since re-roofing still uses new shingles, you won’t have to worr about them being low-quality. In fact, having new shingles installed strengthens your roofing.

Disadvantages of re-roofing

Condition of your old roofing

The only real issue with re-roofing is that it’s not something that can be done of your old roofing is in bad condition.

Some examples of roofing in bad condition include the following:

  • Shingles that are worn-down or curled at the edges
  • Roofing that leaks during the rain
  • Roofing that isn’t physically sturdy

If your current roofing is experiencing any of the issues we mentioned above, you’ll need to have your roofing replaced rather than simply installing new shingles over your old ones.

If new shingles are installed over curled shingles, the new roofing will begin to curl and deform as well. That’s why, before you have new roofing installed over your old one, you’ll need to have your old roofing inspected by a professional roofing contractor.
