Flashing is the metal that seals your roof’s most vulnerable points: valleys, chimneys, skylights, and wall transitions. When a roofer replaces your shingles but reuses the old flashing, they’re leaving your home’s weak spots exposed. Old flashing is bent, corroded, and no longer forms a watertight seal — and it’s also a manufacturer warranty violation. Mr. Goodroof replaces flashing as a standard part of every re-roof. It’s not an upsell. It’s just how it should be done.

Poor attic ventilation is one of the most common — and costly — mistakes made on Nashville roofs. Without proper airflow, heat and moisture build up in your attic, warping decking, shortening shingle life, and driving up your energy bills. Many roofing contractors skip a proper ventilation assessment entirely. Mr. Goodroof evaluates your intake and exhaust ventilation on every project to make sure your new roof can breathe the way it was designed to.

Tennessee’s residential building code exists for a reason — but some roofing contractors cut corners to save time and money, leaving homeowners with non-compliant roofs that can cause problems during home sales, insurance claims, or after severe weather. Common skipped requirements in the Nashville area include proper nail patterns, drip edge installation, and underlayment overlap specs. Mr. Goodroof pulls permits when required and installs to code on every job — because your roof should protect you, not come back to haunt you.

It’s not a scare tactic — it’s an industry reality. Studies suggest that roughly 80% of homes have some form of ventilation problem. In Nashville’s climate, where summers push attic temperatures past 150°F and winters bring freeze-thaw cycles, poor ventilation accelerates shingle deterioration, causes ice damming, and strains your HVAC system year-round. Most homeowners have no idea there’s a problem until the damage is already done. Mr. Goodroof makes ventilation assessment a standard part of every inspection and installation.

Ventilation isn’t just about slapping a ridge vent on the peak and calling it a day. A properly functioning roofing system requires a balance of intake air (typically at the soffits) and exhaust air (at or near the ridge). Without adequate intake, exhaust vents actually pull conditioned air from inside your home — working against you. Mr. Goodroof evaluates both sides of the equation on every project, ensuring your attic moves air the way it was designed to, from bottom to top.

Here’s something most roofing contractors won’t tell you: improper ventilation is one of the leading reasons shingle manufacturers deny warranty claims. Nearly every major manufacturer — GAF, Owens Corning, CertainTeed — includes ventilation compliance as a condition of coverage. If your attic doesn’t meet their Net Free Area requirements, your warranty isn’t worth the paper it’s printed on. At Mr. Goodroof, we install ventilation systems that meet manufacturer specifications, so your warranty is protected from day one.

No two homes ventilate the same way. Attic square footage, roof pitch, soffit configuration, and even your home’s orientation all affect how air moves through your roofing system. That’s why Mr. Goodroof doesn’t use a one-size-fits-all approach. We calculate the specific ventilation needs of your home before a single shingle is installed, designing a system that’s built for your roof — not the house down the street. In Nashville, where weather demands a lot from your roof, that custom approach makes all the difference.
