Why Tearing Your Roof Off Is Always A Good Idea

Sep 5, 2021Blog, Roofing

A roof installation project comes with quite a bit of decision-making and a strong bond of trust between you and your roofing company. One decision that’s important to the performance and longevity of your roof is whether you will be tearing off your old roofing system and installing a new one or installing an overlay on your roof.

A professional roofing company will always recommend that you tear off your old roofing materials and install a brand new rooftop to give your home the best protection possible.

Installing new roofing materials over your existing shingles reduces the lifespan of the new materials you just installed. It also doesn’t allow your roofer to inspect your roof deck’s condition correctly.

There are several reasons why tearing off your old rooftop and installing a new one is the preferred practice over 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

By removing your old roofing materials, your roofer will be able to determine the condition of your roof deck and inspect it for any faults or damages.

Overlaying your roof means that you’re simply adding an extra layer of roofing materials on top of your old worn-out rooftop and therefore have no idea of the condition of your roofing deck.

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

Longer Lifespan

Installing brand new roofing materials after tearing off your old roof will guarantee you a longer-lasting rooftop 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 also traps the cold air trying to exit your attic, thereby increasing the temperatures 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 and these overlaid materials provide reduced protection for your home.

Overlaid materials tend to have a much shorter lifespan than new materials installed directly onto your roofing; it, therefore, makes more sense to install a brand new roof in the first place.
