Composite roofing's definitely a solid choice, especially near the coast. I've seen synthetic slate hold up really well, too. But I'm curious about the installation process—does anyone know if synthetic slate needs special underlayment or sealing to handle coastal humidity? I've done asphalt shingles myself, but never synthetic slate, and I'd imagine moisture control could be different...
"does anyone know if synthetic slate needs special underlayment or sealing to handle coastal humidity?"
From what I've read, synthetic slate doesn't usually need special sealing, but coastal installs often recommend a high-quality breathable underlayment. Personally, I'd still lean toward metal roofing—aluminum specifically—since it resists corrosion surprisingly well near saltwater.
Synthetic slate's pretty tough stuff, and you're right—usually doesn't need extra sealing. But coastal humidity is a sneaky beast, so a breathable underlayment is definitely the way to go. Good call there.
Funny you mention aluminum roofing, though. Had a client once who insisted on steel roofing near the beach because it was cheaper...well, let's just say his roof turned into a rusty modern art piece within a few years. Aluminum, on the other hand, holds up surprisingly well against salty air. Still, synthetic slate has its charm—no rust, no corrosion, and it looks classy without screaming "metal roof."
Either way, sounds like you're on the right track. Coastal roofing can be tricky, but your instincts are solid. Just don't skimp on the underlayment—trust me, it's worth every penny when the storms roll in.
Synthetic slate's definitely appealing, but aluminum roofing isn't half bad either—especially if you're watching the budget. Had a neighbor go aluminum near the coast, and years later it's still holding strong. Just gotta avoid steel...unless rusty chic is your thing.

Agreed, aluminum's solid near saltwater. Another option worth checking out is copper—pricier upfront but practically bulletproof against ocean air. Plus, it ages beautifully...though green patina isn't everyone's cup of tea.
