A commitment to quality

When it comes to quality, details matter. That’s precisely why we’ve spent so much time building relationships with manufacturers who put as much care and attention into their products as we do installing them. For reference, here are the materials and/or services that come standard with every Markelanegelo’s installation: 

  • GAF or Certainteed shingles, high end ice and water shield and roof underlayments

  • Maximum Air roof vents

  • Metal drip edge at all eaves (up gable ends if desired)

  • GAF Weather Blocker or Pro-Start starter strips, which help prevent shingle blow-off

  • New 26-gauge pre-painted steel valley flashing at all valleys

  • New plumbing vent flanges 

  • Maximum Air and Duraflo bath and stove vents

  • Velux fixed mount, curb mount and sun tunnel skylights

  • Eavestrough are cleaned

  • New chimney and wall flashing, prepainted steel chimney caps (if required)

Reducing our footprint

As a Certified Green Roofer, we proudly prevent thousands of tonnes of materials from being buried in landfills every year. 

At every jobsite, you will notice that all of the materials we remove from a roof, including the shingles, metal, and wood, are separated into their own areas. This allows us to load the materials in a specific order, process them separately, and recycle them responsibly.

More specifically:

  • The shingle material we remove from the average roof can be used to pave approximately 40ft of road;

  • The wood we remove is ground down and sent off to the mills;

  • The metal is shipped out of the landfill and recycled.
