FAQs
What exactly is a hidden-fastener metal roof and why is it a great option for homes in Thorn Hill?
A hidden-fastener metal roof—often called a standing-seam roof—uses vertical metal panels whose clips and screws are concealed beneath the seams. Because no fastener holes penetrate the panel surface, there is far less chance of water infiltration or screw loosening over time. For Thorn Hill homeowners, this design delivers three big advantages: (1) superior resistance to the freeze-thaw cycles and heavy snow we experience, (2) a clean, contemporary look that boosts curb appeal, and (3) long-term durability with minimal maintenance.
How long can I expect a hidden-fastener metal roof to last compared with traditional asphalt shingles?
A professionally installed hidden-fastener metal roof typically lasts 40–70 years, with many manufacturers offering 30- to 50-year finish warranties. In contrast, a standard architectural asphalt roof in Thorn Hill generally needs replacement every 15–25 years. The concealed fasteners reduce the risk of premature failure from wind uplift or water penetration, extending the roof’s service life and lowering lifetime costs.
Do I need to replace my gutters when I install a hidden-fastener metal roof?
Not always, but it is often recommended. A new metal roof sheds water (and snow) more quickly than most other roofing materials. If existing gutters are undersized, rusted, or improperly sloped, they may overflow or pull loose under the heavier runoff. When we assess your roof, we inspect gutter size, hangers, downspout capacity, and fascia integrity. If any component is inadequate, replacing the gutters during the roof installation saves labour costs and ensures the whole water-management system performs as one unit.
What warning signs indicate I should replace my gutters in Thorn Hill’s climate?
Look for peeling paint or water stains on soffits and siding, sagging or separated gutter sections, visible rust or pin-holes, pooled water near the foundation, and landscaping erosion beneath the eaves. In Thorn Hill, ice dams and wet snow can also bend aluminum gutters or pull spikes loose. Any of these issues suggest your gutters are no longer directing water safely away from the house and should be repaired or replaced before the next freeze-thaw season.
How much will a hidden-fastener metal roof and new seamless gutters cost in Thorn Hill?
Pricing depends on roof size, panel gauge, colour finish, number of penetrations, and gutter profile. As a ballpark: hidden-fastener standing-seam roofs in the GTA average $9–$14 per square foot of roof area installed. Seamless aluminum gutters (5" or 6") with downspouts run roughly $8–$15 per linear foot, including removal of old gutters. We provide a detailed written quote after an on-site measurement so you know exactly what is—and isn’t—covered.
What is the typical installation timeline and what warranties do you provide?
Once material is ordered, most Thorn Hill residences take 3–6 days for a full roof tear-off, underlayment, standing-seam panel installation, and new gutter system. Larger or complex roofs may take up to two weeks, weather permitting. We offer a 10-year workmanship guarantee on labour, plus manufacturer warranties of 30–50 years on metal panels, paint finishes, and matching accessories. If you choose our premium gutter line, it carries a 20-year no-leak warranty.
