"Panels themselves aren't usually the issue; it's the installer's foot traffic and drilling that can cause trouble."
Exactly right about the foot traffic and drilling. I've seen a bunch of roofs that looked perfectly fine from below but had hidden brittle shingles or weak points. If you're worried about your old roof handling the installation, here's what I'd suggest:
1. Get a thorough inspection first—have someone walk the roof, checking closely for soft spots, cracks, or brittle areas. Better to fix small issues now than deal with leaks later.
2. Ask your installer about their methods. Good installers use foam pads or plywood sheets to distribute their weight and minimize direct impact on shingles.
3. Check if the installer seals drill points with proper flashing or sealant. A careful installer will always waterproof any penetration points to prevent future leaks.
Taking these steps reduces the risk significantly. And honestly, a quick check-up beforehand saves you from dealing with buckets and towels when the next storm hits... been there, done that, not fun.
Good points here, especially about spreading weight with plywood or foam pads. When I had mine installed, the crew was careful, but still ended up cracking a few shingles—thankfully minor stuff. One thing I'm wondering though... if your roof is already borderline, wouldn't it make sense to just replace it first rather than risk having to remove and reinstall panels later? Seems like double the hassle and cost if you wait until after the solar's up.
Replacing the roof first does seem logical, but it isn't always necessary. If your roof has a good 5-10 years left, installing solar now and budgeting for removal later might still be cost-effective. Depends on your specific situation and finances, really...

I generally agree, but one thing to consider—solar panel installations involve drilling holes and brackets into your existing roof structure. Even if your shingles have life left, older roofs can become brittle over time, making them more susceptible to leaks or damage during installation. I've seen roofs that looked decent enough end up needing repairs sooner than expected after panels went up. It's worth factoring in the potential hidden costs before committing...
Yeah, good point about the shingles getting brittle. When I installed my panels, the roof looked decent, but sure enough, a couple months later I noticed small leaks around the brackets.
definitely isn't something to underestimate..."older roofs can become brittle over time"
