Roofing Fire Ratings: UL 790, ASTM E108 and Classes A, B and C
Class A, B and C roof ratings come from three specific fire tests run on a complete assembly. The panel material is only part of it — what sits underneath decides the class.
Commercial Rainware: Internal Drains, Scuppers and Oversized Eavestrough
A commercial roof sheds a lot of water in a hurry. How internal drains, overflow provisions, scuppers and heavy hung trough differ from residential rainware, and what freeze-thaw does to all of them.
Metal Shingles, Metal Tiles and Stone-Coated Steel: Three Different Products
These three often get grouped together as alternatives to standing seam, but they are made differently, installed differently and behave differently on the roof.
Assessing Hail Damage on a Metal Roof
Hail on a metal roof is usually a cosmetic question rather than a structural one — but not always. How to assess it honestly, what to photograph, and what actually matters.
Rake and Gable Trim on a Metal Roof
The rake is the second-highest uplift zone on a roof and the edge everyone sees from the street. One-piece or two-piece, cleated or face-screwed — the choice shows.
Snow Guards on Metal Roofs: Why a Smooth Roof Needs Snow Retention
Metal sheds snow, which is usually an advantage and occasionally a hazard. Here is why a whole slab releases at once, what it weighs, and what snow retention actually does about it.
Sagging or Overflowing Eavestrough: Diagnosing It From the Ground
Where the water goes over the edge tells you what is wrong. Front, back, end or seam each point at a different cause, and metal roofs put demands on eavestrough that asphalt does not.
Trees, Moss and Algae: What Shade Does to a Roof
Shade and retained moisture are what biological growth needs. Understanding the difference between algae, moss and lichen tells you what is happening on your roof and how serious it is.
Wind Uplift Testing Explained: UL 580, UL 1897 and ASTM E1592
Wind does not push a roof down, it pulls it up. Three different test methods measure that pull, they produce different kinds of numbers, and mixing them up leads to bad conclusions.
Metal Roofing for Churches, Halls and Institutional Buildings
Complex geometry, heritage considerations, irreplaceable interiors and a congregation that plans in generations. What makes institutional roofing different, and how these projects get phased.
Standing Seam on Low-Slope Roofs: Minimum Pitch and What Governs It
There is a floor below which a standing seam roof should not be installed. Understanding what sets that floor tells you when metal is right and when a membrane is the correct answer.
Recycled Content and Recyclability of Metal Roofing
Metal roofing is genuinely recyclable, but recycled content varies by mill and the marketing rounds off a lot of edges. Here is how to read the claims and what to ask a supplier for.
Working Through a Roof Insurance Claim: The Process
What the steps in a roof damage claim actually look like, from documenting the event to the adjuster's visit and the scope of work — and what to keep records of along the way.
Valley Construction in Metal Roofing: Open vs Closed
A valley carries the runoff of two roof planes through one narrow channel and fills with ice every winter. Here is how a metal valley is actually built.
Snow Retention Layout: Pad-Style vs Bar-Style, and Why Layout Is Engineered
Two families of snow retention, several variables, and one calculation. Why a single row at the eave is usually wrong, and why guessing at layout fails quietly until it fails all at once.
Storm Damage Triage: What to Do in the First 48 Hours
A clear order of operations after a storm — safety, containment, documentation, then assessment. What you do in the first two days shapes both the repair and the claim.
Spring and Fall Roof Maintenance for Ontario Homeowners
Two inspections a year, timed around the seasons that actually stress a roof here, catch nearly everything while it is still small. Most of it can be done from the ground.
Water and Air Testing for Metal Roof Assemblies
Laboratory tests spray water and measure air leakage across a metal roof panel under controlled pressure. Understanding what they cover — and what they leave out — is the useful part.
Commercial Metal Roof Maintenance and Inspection Programs
Metal roofing is low maintenance, not no maintenance. What a real inspection program covers, which components wear out first, and why the roof file matters as much as the roof.
Curved and Radius Metal Roofing Panels: How They Are Made and Detailed
Metal can be curved two ways, and each one produces a different appearance, a different minimum radius and different problems at the crown of the curve.
How Road Salt and De-Icing Chemicals Affect Exterior Metal in Ontario
Chloride does two things to metal: it raises the conductivity of every water film and it punches through passive oxide layers. Here is how that plays out on Ontario roofs, eavestrough and fences.
Mounting Solar Panels on a Standing Seam Roof with Seam Clamps
Standing seam is the one roof type where solar can be mounted without drilling a single hole. Here's how seam clamps work, what has to be verified, and how to sequence the two projects.
Sidewall and Headwall Flashing on a Metal Roof
Where a roof meets a wall, the flashing has to go behind the cladding, not be caulked to it — and the missing kick-out at the bottom of a sidewall rots more walls than anything else.
Ice Dams on Metal Roofs: How They Form and What Metal Changes
An ice dam needs three things: snow on the roof, a warm deck above the heated space, and an eave below freezing. Metal changes two of them — and leaves the third entirely to you.
