New Fibreglass Shingle Roofs

New construction, additions, and garages — installed to code and built to last

Building new? Replacing a roof is one thing — installing a brand-new fibreglass shingle roof on a new structure requires tight coordination, correct detailing, and a clean finish.

Findlay Roofing installs new fibreglass shingle roofs for:

  • Porches and dormers
  • New homes
  • Additions and expansions
  • Detached garages and workshops

What matters most on a new roof

Decking and preparation

A new roof is only as strong as the substrate. We confirm the deck is sound, correctly fastened, and ready for underlayment.

Water management from day one

We install the right protection at the edges, valleys, and penetrations to handle Ontario rain, snow, and freeze/thaw cycles.

Clean penetrations and flashing

New builds often add:

  • Bathroom/kitchen exhaust vents
  • Plumbing stacks
  • Skylights
  • Roof-to-wall transitions

We make sure these are integrated correctly — not patched in later.

Ventilation planning

We review intake/exhaust requirements so the attic space (or roof cavity) performs properly from the start

Shingle selection and style

Architectural fibreglass shingles provide a dimensional look that complements most Ontario home styles. We install trusted brands including GAF, CertainTeed, IKO, BP, and Owens Corning.

Our process for new roofs

  1. Scope and coordination — align with builder/homeowner schedule
  2. Installation plan — penetrations, valleys, edges, ventilation
  3. Certified installation — built to spec with clean finish work
  4. Final walkthrough — confirm details and site cleanup
