"Doing it right the first time around"

Flashing and Metalwork

Unlike some competitors who cut corners to present lower quotes, we believe in complete transparency and quality. It’s important to compare equivalent services: often, if a deal seems too good to be true, it probably is. The cost difference usually comes from omitting essential replacements like step flashing and counter flashing, which are necessary for a thorough and durable roofing job.

Every quote from Boston Roofing includes the necessary replacement of flashing to ensure your roof is set up for long-term success. Some contractors might choose to install straight counter flashing to save on labor costs, but this method doesn’t comply with building codes. We adhere strictly to building standards, and we utilize the “shark tooth” method for all our flashing, providing a tighter, more effective seal. This is coupled with 22 gauge aluminum flashing in a range of colors with a durable baked-on finish, ensuring both functionality and aesthetic appeal. Remember, a quality roof should be as well-dressed as you are—never compromise style for substance. “There’s no use wearing an Armani suite with a $10 pair of shoes.”

Types of Flashing

Step Flashing: This preliminary flashing is vital for sealing the roof to the wall. Many contractors skip replacing old step flashing, but at Boston Roofing, we replace and seal it with high-grade silicone caulking for a lasting fit that doesn’t rely solely on counter flashing to prevent leaks.

Counter Flashing: Our “shark tooth” style not only meets code but ensures a flawless finish with no visible kinks or dents, ensuring your home looks outstanding. Like our step flashing, it’s sealed with high-grade silicone for enduring protection.

Choose Boston Roofing for your next project and experience the difference that comes with dedication to quality and detail. We’re not just roofing experts; we’re craftsmen who care about every component of your roof.
