A residential roofing system is usually installed via two methods: a complete tear-off or a roof-over. The first one involves tearing off the entire roof before installing a new system, while the latter simply layers new shingles on top of the old one. Most building codes allow for this type of installation, but is a roof-over actually a good investment?
Affordable Roofing Systems, the leading roofer in the region, helps you weigh the pros and cons of this method.
The Pros of Roofing Over Existing Shingles
The most notable advantage of a roof-over over a complete tear-off is that it costs significantly less. With this option, you’ll save on demolition, labor, disposal, materials and recycling costs. It helps you save time as well since you won’t have to remove your existing shingles and deal with the mess that comes with tear-off.
The Cons of Roofing Over Existing Shingles
Unfortunately, choosing this method will shorten the life of your roof because the added layer of shingles traps heat, causing the materials to deteriorate faster. This may prompt you to get roof repairs to help provide quick solutions to your roof-over issues.
Additionally, a second layer of shingles can add up to 450 extra pounds on your system. This can result in severe structural damage over time. Snow and rainfall can further burden your roof and your entire structure, trapping moisture and causing rotting or decay.
As you can see, a roof-over presents more cons than pros. It may help you save on initial costs, but it won’t be worth it in the long run. For your roof to last longer, it’s best to choose a complete tear-off when deciding on a roof replacement.
