When your roof is worn or leaking you know it’s time for a repair, but do you need a full roof replacement? Depending on the condition and materials of your roof, you may have the option to re-roof, which is more cost-effective than a roof replacement. Know the difference between the two and keep these points in mind when deciding on which route to take.

A Guide to Re-Roofing

How Does Re-Roofing Work?

During a re-roofing, a roofer adds a layer of shingles on top of the shingles already on your home to repair damage. There’s typically three to four layers to a roof, and since these layers are staying intact and are not being torn off, there’s less work and materials involved, making it a quicker and more affordable option.

Who Should Re-Roof?

Re-roofing typically doesn’t last as long as a roof replacement and isn’t for every roof. Because of international building codes, only roofs with one layer of shingles can be re-roofed. You cannot add a third layer of roofing to an existing roof.

Re-roofing is a good choice if you have asphalt shingles and you’re updating the look of your roof or fixing the entire roof. Your roof can be old but needs to be in overall good condition. This means the roof may have minor leaks but no water damage, including soggy or missing shingles. 

Additionally, you must know that the bottom layer of your roof, known as decking or sheathing, is in good condition. Existing shingles may cover up problems like sagging or rotting, which can cause major problems down the road.

A Guide to Roof Replacements

How Do Roof Replacements Work?

During a roof replacement, the roofer will tear off all layers down to the deck. They’ll inspect the deck and repair it if necessary. The roofer will install a new underlayment, which is a felt layer that protects against water and helps shingles to lay flat, and all new shingles. A roof replacement should come with a warranty and last between 10 and 50 years, depending on the materials used.

Who Should Have a Roof Replacement?

While roof replacements are an option anytime, a roof replacement is necessary if your roof already has a second layer. It’s also necessary if you have missing, curling or damaged shingles, or your roof is in overall poor condition.

You should consider a roof replacement if the structure has more than a few minor problems or you are unsure about or suspect damage to the decking. A roof replacement will answer any questions you may have about the condition of your roof and potentially save you money down the road.
