A roof is more than a cover; its shape defines curb appeal, weather‑proofing, and long‑term cost. Whether you’re restoring a century-old home near Hurontario Street or building a chalet at Blue Mountain, choosing the right profile is crucial. Below, we unpack the seven roof shapes most common to Collingwood roofing projects—and show how Ainger Roofing tailors each one for Georgian Bay’s demanding climate.
1. Gable (Peaked) Roof
The classic two‑slope “A” frame sheds snow efficiently and ventilates attics with ease—important in lake‑effect zones. Ainger Roofing reinforces gable ends with hurricane ties and uses drip‑edge metal to stop ice dams before they start.
2. Hip Roof
With four equal slopes meeting at a ridge, hip roofs offer superb wind resistance—ideal for Collingwood’s open shoreline lots. Our crews use pre‑cut hip caps and woven valleys to create a watertight, sculpted look that boosts resale value.
3. Gambrel (Barn) Roof
Popular on rural properties, a gambrel provides full‑height loft space without adding a second storey. Ainger specifies engineered trusses and continuous ridge vents so your roomy attic stays dry and mould‑free.
4. Mansard Roof
Think “French cottage”: a steep lower slope topped by a shallow upper deck. Mansards allow dramatic dormers and extra living space. We combine high‑definition architectural shingles on the lower face with a hidden membrane on the flat crown for a seamless aesthetic.
5. Shed (Skillion) Roof
A single‑plane roof pitches in one direction—perfect for modern additions or covered porches. Because snow can drift at the high wall, Ainger installs custom‑flashed kick‑out diverters and self‑adhered ice‑shield 6 ft up the slope.
6. Flat Roof
Commercial buildings and contemporary homes often opt for low‑slope membranes. Our Torch‑on SBS or TPO systems include tapered insulation to eliminate standing water and come with 20‑year no‑leak warranties.
7. Butterfly Roof
Two descending planes form a central valley, directing rainwater to a hidden downspout for greywater reuse. Ainger Roofing lines the valley with 60‑mil EPDM and integrates scupper boxes sized for Collingwood’s heaviest storms.
