FAQs
Why is metal roofing recommended for homes and businesses in Thorn Hill that face gale-force winds?
Metal panels are interlocked and fastened to the roof deck with high-strength screws and clips, creating a continuous, rigid surface that resists uplift far better than shingles or tiles. In Thorn Hill, gusts can exceed 110 km/h during spring and fall storms; metal roofing is engineered and tested to stay in place at those wind speeds, reducing the risk of water intrusion and costly storm repairs.
How are your metal roofing systems tested for wind resistance?
Our panels undergo ASTM E1592 (uplift) and UL 580 (wind uplift) laboratory testing. These tests simulate gale-force winds by creating negative pressure beneath the panel until failure. The profiles we install in Thorn Hill are rated to withstand uplift pressures equivalent to winds of 190–220 km/h, well above local extreme wind records, giving you a comfortable safety margin.
Will high winds cause metal panels to rattle or make noise?
Properly installed metal roofs are quiet. A breathable underlayment and foam closure strips buffer the panels from the deck, while concealed fasteners lock each sheet tightly in place. Wind-generated vibration is virtually eliminated, so you hear little more than you would with asphalt shingles—often less, because metal panels shed rain quickly and don’t absorb water.
Does installing a metal roof for wind protection require structural upgrades to my existing roof framing?
Most Thorn Hill homes can accept metal roofing without additional framing because the material is lightweight—40–50 kg per 100 sq ft, about half the weight of asphalt shingles. We inspect your attic for rafter spacing, sheathing thickness, and fastening patterns. If the deck or trusses show age-related weakness, we’ll recommend affordable reinforcements before installation to ensure the system meets wind-load code requirements.
How long will a wind-rated metal roof last, and what maintenance is involved?
Metal roofs typically last 40–70 years. Their baked-on Kynar or SMP paint finishes resist salt spray, UV, and acid rain, so color fading is minimal. Annual maintenance involves clearing leaves from valleys and gutters, inspecting sealant at penetrations, and checking for loose trim. Because panels don’t crack or curl, your wind resistance remains intact throughout the roof’s life.
Are there insurance or permit advantages to choosing metal roofing for gale-force wind protection?
Yes. Many insurers offer 5–20 % premium discounts for UL 2218 Class 4 impact-rated and high wind-rated metal roofs, reflecting their lower risk profile. Thorn Hill falls under the Ontario Building Code’s High Wind Zone B; our installation package includes engineering letters and permit support that streamline approval with the local municipality, saving you time and often reducing permitting fees.
