Keep Your Roof Performing Its Best

Routine inspections and maintenance can help extend the life of your roof.

Keep Your Metal Roof Performing Like New

One of the biggest advantages of a metal roof is its exceptional lifespan, but like any roofing system, it requires periodic maintenance to perform at its best.

If your metal roof uses exposed fasteners (screws), those fasteners can loosen, back out, or experience washer deterioration over time due to decades of temperature changes, wind, and weather exposure. Replacing aging screws before leaks develop is one of the most effective ways to extend the life of your roof.

At Refined Roofing, we provide professional metal roof maintenance, inspections, and screw replacement throughout Halifax and Nova Scotia.

Why Do Metal Roof Screws Need Replacing?

Metal roofing expands and contracts every day as temperatures change.

Over thousands of heating and cooling cycles, this movement can gradually cause screws to loosen. At the same time, the rubber sealing washers beneath the screw heads naturally age from UV exposure and weather.

Common issues include:

  • Loose or backed-out screws
  • Cracked or deteriorated rubber washers
  • Small water leaks
  • Rust around fasteners
  • Reduced wind resistance


Fortunately, these issues can often be corrected without replacing the entire roof.

Signs Your Metal Roof Needs Maintenance

You may need a metal roof inspection if you notice:

  • Water stains on ceilings
  • Leaks after heavy rain
  • Visible screws sticking up
  • Missing fasteners
  • Rust around screw heads
  • Loose flashing
  • Roof is 10–20+ years old
  • You’ve never had a maintenance inspection


Even if your roof isn’t leaking, preventative maintenance can help avoid much larger repair costs later.

Our Metal Roof Maintenance Services

Our maintenance service may include:

  • Complete roof inspection
  • Replacement of deteriorated screws
  • Installation of oversized replacement fasteners where needed
  • Replacement of failed rubber washers
  • Tightening loose fasteners
  • Flashing inspection
  • Sealant inspection
  • Leak investigation
  • Minor metal roof repairs
  • Photo documentation


Every roof is different, so we’ll recommend only the work your roof actually needs.

Should Every Screw Be Replaced?

Not always.

Some roofs only require replacing the fasteners that have begun to fail, while older roofs may benefit from a full screw replacement.

Our inspection helps determine:

  • Age of existing fasteners
  • Condition of washers
  • Amount of movement
  • Signs of corrosion
  • Overall roof condition


We’ll explain your options before any work begins.

How Often Should a Metal Roof Be Inspected?

We recommend:

  • Every 3–5 years for most exposed-fastener metal roofs
  • After major wind events
  • Before buying or selling a home
  • If your roof is over 10 years old


Routine inspections help catch small issues before they become expensive repairs.

Protecting Your Roof Warranty

Many metal roofing systems require regular maintenance to help ensure they continue performing as intended. Replacing worn fasteners, repairing damaged flashings, and addressing minor issues promptly can help prevent water intrusion and avoid more extensive repairs down the road.

If your roof is still under warranty, it’s important to follow the manufacturer’s maintenance requirements. Our team can inspect your roof and recommend maintenance that aligns with your roofing system.

Insurance & Preventative Maintenance

A well-maintained roof helps protect your home, and may also help during future insurance inspections. Loose fasteners, active leaks, corrosion, and deferred maintenance can raise concerns if your roof is being evaluated for coverage or renewal.

Routine inspections and timely screw replacement help identify small issues before they become costly repairs. If requested, we can also provide photographs and documentation of your roof’s condition following an inspection.

Why Choose Refined Roofing?

Our team specializes in both asphalt and metal roofing systems. We understand how different metal roof profiles age and know what to look for during maintenance inspections.

We don’t just replace screws, we inspect the entire roofing system to ensure your investment continues protecting your home for decades to come.

Daily expansion and contraction of the metal panels gradually works fasteners loose over many years. Wind vibration and aging rubber washers also contribute.

Sometimes, but older screws often have deteriorated washers or worn threads. Replacing them with new fasteners is typically the longer-lasting solution.

Pricing depends on the roof size, accessibility, number of fasteners needing replacement, and overall roof condition. We provide a detailed inspection before recommending any repairs.

Yes. Failed fasteners are one of the most common causes of leaks on exposed-fastener metal roofs. Replacing damaged screws and washers often resolves these issues.

Generally no. Standing seam systems conceal the fasteners beneath the panels, making them much less susceptible to fastener-related leaks. Maintenance for standing seam roofs typically focuses on flashings, sealants, and general inspections rather than exposed screw replacement.
