Roofing Over an Existing Roof: What You Need to Know

When you start to notice problems with your roof, or as it nears the end of its useful life, it's probably time to make some big decisions. You may be wondering about the roofing options you have and what will be the best solution for you. The best thing to do then is to call a professional roofer and discuss it with them, as they have the experience and expertise to guide you in the right direction.

If the condition of your roof is such that a couple of repairs will not be enough to get it back into shape, but it is still functional enough that it is not necessary to tear it off and replace it completely, then you should think about re-roofing, that is, installing a new roof over your existing one.

The difference between Refocusing and Roof Replacement

Roofing over an existing roof is also called re-roofing or overlaying. It is the process in which roofers install a new roof over the existing one, that is, they add a new layer of shingles, which means that the old roof is not broken. It is important to know that this process can only be done once because you can only have two layers of shingles on your roof.

Roof replacement is the process of installing a completely new roof that includes tearing off the old one. Roofers will tear off almost everything, right down to the roof deck, and basically start from scratch with the new roof, from laying felt paper to installing shingles.

Since roof replacement involves tearing off everything, it can be done on every roof, regardless of the number of layers of shingles, all will be removed in any case. Roof replacement involves much more time and labor, and is therefore more expensive than re-roofing.

When put a New Roof over an Existing Roof?

When your roof starts to fail, but is in good overall condition, a re-roof may be the best option for you. What does it look like to me to have a roof that is failing but still in relatively good condition? It means that your roof may be at the end of its useful life, but its underlying structures and sheathing are in generally good condition.

By adding another layer of quality shingles to your roof, you are actually adding one more protective layer to your roof. This, along with the underpayment, roof sheathing and original layer of shingles, will work as a combined protection against damage and prevent leaks from entering your home.

We see this layer as an enhancement, or even a rejuvenation, of your roof that increases its protection against leaks. In addition, it will help direct water from your roof into your gutters and downspouts, avoiding the problem of pooling.

When is it not a Good Idea to put a New Roof over an Existing Roof?

A professional and honest roofing contractor should always warn you if your roof is not a good candidate for an overlay or new coating. That is what a roof inspection is for and should always be done before any action is taken on the roof.

After a thorough inspection, a roofer will come to you with his report or a recommendation, explaining why your roof is or is not ready to be remodeled.

What should you do?

Retrofitting is a great option for those who don't need a complete roof replacement, unlike a roof replacement, it doesn't involve tear-off, which means it reduces both the time and cost of the project.

It's always a good idea to consult with a trusted roofer, who can do an inspection, give you an accurate estimate and advise you on which option is best for you.
