Whenever that dreaded recommendation arrives from your roofer — it's time to replace your existing roof — many homeowners panic and immediately begin to mentally subtract zeros from their bank account. After all, a roof replacement is certainly an investment. However, some roof replacement jobs only require new shingles and that can save a lot of money. That's because the average roof consists of a few essential parts: plywood decking, underlayment, flashing, and a few other options depending on your climate. Here are a few situations that might work in your favor so you can save costs.

Where You Might Save

Decking

The biggest factor in the decision to leave or replace the decking depends on its condition once the existing shingles are removed. Your roofer will make a recommendation based on the age of the decking material as well as its condition. A roof deck is typically made of plywood sheets. On a roof, plywood will last about 30 to 40 years, so if your decking is younger than that and in good condition without damage from water leaks, it shouldn't require replacement and that will save you quite a bit.

Flashing

Another way to save costs is if your flashing is still in good condition. Flashing is the thin galvanized steel sheets that roofers use to direct water away from sensitive areas such as places where the shingles meet a new surface like a chimney or vent. Although flashing is fairly inexpensive, it's certainly not free. So if you can avoid replacing it at the recommendation of your roofer, you'll spend less.

What You'll Have To Pay For

Shingle Removal

While it's possible to get up on your roof and strip off the old shingles before the roofers arrive, it's certainly not recommended and it likely won't save you that much. That's because your roofer will include the cost of hauling away and disposing of the old shingles in their estimate. And your roofer can likely do it much more cost-effectively than you can. And of course, it's obviously very dangerous for you to do the job if you have no experience on a roof. Losing your life or a limb is not worth saving a few extra bucks.

Underlayment

You'll also need to factor in the cost of underlayment or the thin sheet of synthetic material that sits between your deck and shingles. Underlayment protects the deck and your home from water and weather. It's important to invest in a quality product and not reuse old material.

Shingles

And obviously, you'll need to pay for the cost of new shingles. Make sure to consult with your roofer about the best quality product for your particular roof.
