Metal Roofing in Blaine
Installation, replacement and repair on Blaine roofs, specified for constant salt air and constant wind off the Strait of Georgia.
Blaine is the most corrosive environment we work in, and it is not close. A border town sitting on Drayton Harbor with Semiahmoo across the water, exposed to the Strait of Georgia, getting salt carried onto it more or less continuously. Roofs here age at a different rate from roofs fifteen minutes inland, and the ageing shows up in a specific order: fasteners first, then flashings, then coating, and only then the panels.
That order is the useful thing to know, because it means the failures here are usually at the parts that are cheapest to specify well in the first place and most expensive to fix later. A fastener choice that is perfectly reasonable in Bellingham can be a mistake in Blaine, and the difference in price at the time of installation is small.
The housing runs from older waterfront cottages through retirement builds to newer view homes, and the older stock in particular tends to carry a lot of accumulated repair history that is worth understanding before adding to it.
In this town
What we do in Blaine
Metal Roof Installation
New metal specified for a marine environment. Panel coating, fastener material and flashing compatibility all get decided differently here, and it is the whole reason to use somebody who works this coastline.
Metal Roof Replacement
Older roofs on the waterfront stock, both composition and metal, coming off. Corrosion under a coating is frequently worse than it looks from the surface, so what is found at tear off matters more here.
Metal Roof Repair
Fastener and flashing corrosion is the dominant repair here by a wide margin. Catching it while it is still fasteners rather than panels is the difference between a repair and a replacement.
Metal Roof Inspections
Worth more in Blaine than almost anywhere else we work, because the damage is progressive, predictable and largely invisible from the ground until it is advanced.

Local detail
What is different about a Blaine roof
Salt finds the fasteners first
Exposed fastener roofs age fastest here, because every screw head is a small piece of exposed metal in a corrosive environment. It is the strongest argument for standing seam on this coastline, and one of the few places we make that argument on durability grounds rather than aesthetic ones.
Dissimilar metals are a real problem, not a technicality
Incompatible metals in contact corrode faster than either would alone, and salt air accelerates it substantially. Flashing material, fastener material and panel coating have to be considered together. This is the single most common thing we find done wrong on Blaine roofs.
Wind and salt at the same time
Wind off the Strait drives salt laden moisture into edges, laps and under panel edges rather than depositing it politely on the surface. Edge detailing here is doing two jobs at once.
Older cottages carry history
A lot of the waterfront stock has been repaired repeatedly over decades, sometimes well and sometimes with whatever was available. Working out what is actually on a roof before adding to it is often the first hour of the job.
Questions
Blaine roofing questions
How much does a metal roof cost for a 3,000 sq ft house?
Worth adding for Blaine specifically: a marine specification costs somewhat more than the same roof inland, because the fastener, flashing and coating choices are upgraded deliberately. That difference is small at installation and large if it is skipped.
Cost figures are not published here yet. We will not put a number on a page that we have not stood behind on a roof, so ask and we will price your roof.
What is the best coating to put on a metal roof?
It depends on what the panel is and what it is being asked to survive, which is why nobody should give you a single product name for it. In a salt environment the coating is doing more work than it would inland, and compatibility with the existing surface matters more than the marketing on the tin. What we can say confidently is what fails: coating applied over a dirty or damp surface, coating applied over active corrosion that was not treated first, and general purpose products used on a roof that needed a marine specification.
How much does it cost to replace a roof on a 4,000 square foot house?
A four thousand square foot house is usually a complex roofline as well as a large one, and complexity is the more expensive of those two properties. Every dormer, valley, chimney and skylight is a flashing detail rather than a run of panel. Get the scope itemised before comparing quotes, because at this size two quotes can differ by a very large amount and still both be honest.
