Reasons to Avoid Installing a New Roof Over Your Old One

By Stacy Mellete

Residential roof repairs St. Petersburg Florida and replacement projects are not easy tasks. In fact, it’s a worthy investment that requires a significant amount of time and funds to complete. When you’re planning a roof replacement, you may be offered to opt for nailing a new roof over an old one instead. According to experts, this is an offer that you should always refuse.

Here’s why:

Voided Warranty

One of the reasons you shouldn’t install a new roof over your old one is because you don’t want to void your warranty. Roofs must be installed according to the specifications of the manufacturer and failing to do so can void your new roof’s warranty.

Added Weight

Nailing a new roof over your old one can also add unnecessary weight to your roof, which can compromise the structural integrity of your roofing system and cause it to sag. You can get additional construction work done to support the added weight, but that will add to your roof replacement costs.

Shortened Lifespan

Another reason why you should never install a new roof over your old one is because it can shorten the lifespan of your new roof. According to residential roofing in St. Petersburg FL pros, this is because the new shingles can absorb more heat, wearing out the shingles faster than they should.

Inspection and Installation Mistakes

By not tearing off your old roof before installing the new one, your roofer won’t be able to conduct the proper inspection procedures to spot any kind of damage that may need to be repaired before installing the new roof. Apart from that, not removing the old roof can also prevent your roofers from installing a new ice and water shield, which are crucial in preventing leaks on your roof.
