Been dealing with rust and corrosion on my roof since moving near the beach, and learned the hard way that aluminum flashing and stainless steel nails are total lifesavers. Anyone got other handy tricks for roofs exposed to salty sea air?
- Definitely consider a good quality roof coating. I've used acrylic elastomeric coatings on a couple coastal properties, and it made a noticeable difference in resisting corrosion.
- Also, regular rinsing with fresh water helps a ton—sounds basic but salt buildup is sneaky.
- And don't underestimate ventilation. Good airflow under the roof sheathing really cuts down moisture buildup and rust issues.
Been there, done that... coastal living's great, but the maintenance is no joke.
Good points on ventilation and rinsing, but I'm not totally sold on acrylic elastomeric coatings for coastal roofs. I've tried them before, and while they do help initially, I've found silicone-based coatings hold up better long-term against salt and UV exposure. Acrylic tends to degrade faster, especially under intense sun and salty conditions. Just my two cents—might depend on your exact location and roof type though...
I've had similar experiences with acrylic coatings—initially promising but not exactly built for the long haul in coastal climates. Silicone does seem tougher on UV and salt, but one thing I've noticed is silicone can be tricky if you ever need repairs or recoating down the line. Adhesion becomes an issue without careful prep.
Recently, I've been exploring urethane-based coatings. They're pricier, yeah, but from what I've read and seen firsthand on a neighbor's roof, they strike a good balance between durability and ease of maintenance. He applied it about four years ago, and it's holding up impressively against salty spray and intense sun.
Have you or anyone else here tried urethane coatings? Curious if you've seen different results or have tips on application...
