Salt air is hard on roofs, but why? Corrosion is one of the most underrated roofing problems in coastal Maine, and here’s what’s actually happening. And what you can do about it.
Why Salt Air Is Hard on Roofs
You don’t have to own a beachfront property to see and feel the effects of salt air on your roof. Saltwater is aerosolized when waves break, and the wind carries it inland. So while the highest concentration of salt air is near the shoreline, your inland home may still be impacted by Maine’s unique geography.
That means homes as far inland as Berwick aren’t off the hook. Precision Roofing understands these regional impacts and can help you repair, maintain, or install roofing that lasts in this seaside state.
Salt Air and Shingles: What Happens
Despite the salt air’s side effects, asphalt shingles are the most commonly installed roofing material in Maine. However, salt air affects them in a very peculiar way.
Salt can accelerate granule loss, leaving your home unprotected against harmful UV rays and weathering. Coastal properties are especially prone to this issue because of their close proximity to the water. But without those granules, asphalt shingles can crack, curl, or become brittle and break.
Once salt air destroys roof granules, the underlying asphalt is exposed to direct sunlight. Your roof ages much faster, becomes less flexible, and can begin failing before reaching its full lifespan. What might have lasted 20-30 years now lasts 10-15, even with excellent maintenance.
Salt Air and Metal: What Happens
Every roof has metal around gutters, drip edges, vents, and fasteners. And unfortunately, these are the components that are usually the first to show wear from salt air exposure. Salty air can quickly cause rust on flashing and metal roofing, particularly galvanized steel.
Water intrusion frequently starts where a rusted fastener ends. Precision Roofing can assess your roof for damage or potential issues and provide practical solutions to prevent further problems.
Moisture in Maine and What It Means for Your Roof
Salt air corrodes, but it also holds onto moisture. Over time, this can cause increased humidity levels around your roofing system. And increased humidity means one thing: mold and mildew.
Mold and mildew can weaken your roofing materials and structure. It can also cause leaks if left unattended. In coastal areas, where ambient moisture is already a factor, additional retention can cause significant problems.
What to Do Next
Fortunately, salt air damage is manageable and reversible. Here are some tips that might help make a difference:
- Consider metal roofing with marine-grade coatings
- Evaluate the pros and cons of standing seam roofing systems
- Schedule regular roof inspections to catch issues before they escalate
- Rinse or clean your roof and gutters at least once per year
- Work with a trusted roofing company in Maine for the best results
