The right way to roof: Why one layer is all you need

By The Third Estimate. 

A strong, healthy roof starts with smart choices, so begin with a clean slate! 

When it comes to roofing, cutting corners isn’t saving; it’s setting you back. At The Third Estimate, we believe the smartest investment you can make in your home starts at the top. Installing a single, properly sealed layer of shingles doesn’t just protect your roof; it protects your home, your wallet and your peace of mind. If you’re weighing your options, this is your chance to make the choice that pays off for years to come and invest in the proper single layer of shingles. 

So, what’s the problem with layered shingles? 

1 – Weight that your roof can’t handle 

Roofs are designed to support one layer of shingles, not two (and definitely not three). Adding more weight than it was built for can strain the structure, leading to sagging, cracking or even collapse over time. Think of it like wearing three winter coats in July, heavy, sweaty and totally unnecessary. 

2 – You’re trapping problems underneath 

When new shingles are laid over old ones, there’s no way to see what’s going on underneath. Leaks, rot, mold and damaged decking all get buried and ignored. By the time you realize something’s wrong, the damage is deep and costly. 

3 – It shortens the life of your roof 

Shingles are made to lie flat on a smooth surface. Layering over old, curled or damaged shingles means the new layer doesn’t seal properly. That opens the door for wind, rain and ice to do their worst, speeding up wear and tear. 

4 – Warranties can get voided 

Most manufacturers and roofing companies won’t honor warranties if shingles are improperly installed over an old layer. So, if something fails, guess who’s footing the bill? You! 

5 – You’re just delaying the inevitable 

A second layer doesn’t solve problems; it hides them. And when the time finally comes to replace everything (because it will come), it’ll cost more to tear off multiple layers and repair the damage underneath. 

So, what should you do? 

If your home has layered shingles, don’t wait for signs of damage. Have your roof inspected by professionals who can give you a clear picture of what’s going on up there. In many cases, a full tear-off and proper replacement is the smartest (and safest) investment you can make.
