And how to stop it.
Gravenhurst Roofing
Follows Different Rules
The first Muskoka town off Highway 11.
Snow loads, freeze-thaw cycles, vacant winters.
Most contractors from outside the region
never plan for any of it.
- ❄
282.7 cm of snowfall per year (Environment Canada). That weight sits on uncleared cottage roofs from November through March
- 🏚
Unheated cottages trap moisture under decking all winter. Decking softens before owners arrive in May
- 🌊
Waterfront properties on Lake Muskoka and Muldrew Lake face open-water wind. Ice at the eaves builds faster than on sheltered streets
- 📋
We serve Winewood Avenue, Bay Street, Sharpe Street, and Bethune Drive, plus all Gravenhurst-area lakes
What Causes Roof Damage
on Gravenhurst Properties
Most Gravenhurst roofs don’t fail because of age.
They fail because of how the building is used. Or not.
| Property Type | Most Common Problem | Root Cause |
|---|---|---|
| Vacant cottage | Moisture under the decking | Unheated. No attic airflow all winter |
| Waterfront home | Ice dams at the eaves | Freeze-thaw plus open-water wind |
| Heritage home, Bay Street | Flashing failure, aged decking | 50 to 70 year old structure |
| Flat roof commercial | Pooling, membrane split | Snow load plus drain failure |

The Crew Behind
the Work Since 2002
Every project. Our own team.
No subcontractors. Ever.
Marcy Dennis founded Advanced Roofing Muskoka in 2002.
Early on, a replaced roof near Muskoka Falls Road kept getting ice dams.
The shingles were fine.
The attic ventilation had never been fixed.
That one job changed how this company works.
Not every roofer knows why they keep returning
to the same house year after year.”

People here are careful decision-makers.
They are not chasing deals.
They want the right fix.
I’ve seen homeowners replace roofs too early.
I’ve also seen small leaks ignored until damage spread.
The common issue was guidance.
Not effort or budget.
Trust builds when risks are explained clearly.
That matters more than promises.
