Why Tearing Your Roof Off Is Always A Good Idea

Jun 14, 2021Blog, Roofing

When it comes to installing your home’s new roofing system, there are many factors that you need to consider before the installation process begins.

One decision that will have a huge effect on the longevity of your roof is whether you should opt for an overlay or tear off and install new shingles.

Tearing off your old roofing materials and installing brand new materials gives your home the best protection possible as new materials have not yet been exposed to the elements.

If you have shingles on your roof, installing new materials over them is not a good idea. It will reduce the lifespan of what just got installed, and it won’t allow for any inspection to be done correctly either.

There are many reasons why tearing off your old roofing system and installing a new one is so much better than installing an overlay on your existing roof.


Here are some of the reasons why you should always tear off your old roofing before installing a new one:


Roof Deck Inspection

To avoid any roofing disasters, it is important that you have your old roof removed so the condition of the deck and possible damages can be inspected.

By overlaying your roof, you will simply be adding a layer of roofing materials on top of your old roof and thus have no idea of the state of your roof deck.

If your roof deck has deteriorated and starts to affect the interior of your home, you would have to go back and remove your brand new roofing materials to repair or install a new roofing deck.


Longer Lifespan

Installing new shingles after a roof tear-off process will always last longer than an overlay roofing system. Several layers of shingles will lead to the trapping of excess heat beneath them. This constant presence of heat will lead to your shingles curling and breaking. This heat will also trap any cold air trying to escape your attic, thus maximizing the temperature inside your home.


Overlays Can Only Be Completed Once

Overlaying your roof is only a one-time solution. It cannot be completed too many times as the multiple layers will add excess weight and strain to your home’s structures. It is thus not a sustainable solution for your roofing system or your home.

Because overlaid materials have a much shorter lifespan than that of a newly installed roofing system, it makes more sense to install a brand new roof in the first place.
