A Step-by-Step Guide to Your Metal Roofing Project

Selecting the Best Metal Roofing Profile for Your Build

Installation Day Through Final Project Handover




Most residential metal roofing installations in Tillsonburg are completed within two to five days, depending on the size and complexity of the roof. Commercial projects generally require more time. Factors such as weather disruptions and any decking repairs discovered during the job can also extend the overall duration.
The key metal roofing cost factors include the type of panel profile selected, the total surface area to be covered, roof steepness, the number of penetrations requiring flashing, and whether existing roofing materials must be torn off beforehand. Standing seam systems tend to carry a higher price than Tuff Rib through-fastened panels because of the more complex materials and installation labor involved.
A standing seam metal roof relies on concealed fasteners and raised interlocking seams, producing a sleeker profile with fewer points where moisture could potentially enter. Tuff Rib panels use exposed fasteners and a corrugated ribbed design that is quicker and less expensive to install, making them a popular choice for farm buildings, commercial applications, and cost-conscious residential projects.
In certain circumstances, metal panels can be installed directly over existing shingles, provided the decking is structurally sound and local building regulations allow it. However, a proper site assessment is always necessary first to check for moisture damage, evaluate structural capacity, and confirm that the added weight will not pose any concerns.
When correctly installed and maintained, metal roofs in Southwestern Ontario typically perform well for between 40 and 70 years. This represents a considerable advantage over asphalt shingles, which usually need replacing every 15 to 25 years depending on the product quality and local weather exposure.
