NEED ADVICE ON REPLACING AN OLD LEAKY ROOF
Yeah, I’m with you on the baffles—people skip that step way too often and then wonder why their attic’s still a sauna. I’ve seen jobs where folks just stuffed insulation right up to the roof deck, thinking the soffit vents would magically fix airflow. Doesn’t work like that. You need that clear channel from soffit to ridge or you’re just trapping moisture and heat.
One thing I’d add: if your house is older and the rafters are on the shallow side, it can be a pain to fit both enough insulation and a proper vent chute. Sometimes you have to get creative with thinner baffles or even spray foam in certain spots, just to keep that air moving. Also, if you’re in an area with a lot of wind-driven rain, make sure your vent screens are tight—seen a few cases where critters or water found their way in.
Maintenance-wise, I agree it’s not a huge deal unless you’ve got a ton of pine needles or leaves. Just don’t forget about it for years at a time... out of sight, out of mind, right?

- Baffles are definitely overlooked, and you’re spot on about the airflow. I’ve walked into too many attics where insulation is jammed right up to the roof deck—no venting, just a recipe for mold and warped sheathing down the line.
- If you’re dealing with shallow rafters, here’s what’s worked for me:
- Use rigid foam baffles—they’re thinner than the cardboard or plastic ones and hold their shape better.
- In really tight spots, closed-cell spray foam can be a lifesaver. Just make sure you’re not blocking the vent path. Sometimes you have to trim it back after it cures.
- I’ve also seen folks use 1x2 furring strips to create a little extra space for airflow before adding insulation. Not always pretty, but it works.
- On vent screens: totally agree. I’ve had squirrels chew through cheap mesh and end up nesting in the soffit. Stainless steel hardware cloth is worth the few extra bucks if critters are an issue.
- Maintenance—yeah, it’s easy to forget about those vents until you get ice dams or notice your attic smells musty. I try to check mine every fall when I’m up there anyway for other stuff. Pine needles are a pain, but even dust and cobwebs can add up over time.
- One thing I’d add: if you’re replacing the whole roof, think about adding a ridge vent if you don’t already have one. It’s a game changer for attic temps, especially in older homes that weren’t built with much ventilation in mind.
- Last bit—don’t skimp on underlayment. Peel-and-stick membrane along the eaves and valleys can save you from leaks if ice dams are a problem in your area. I learned that the hard way after a brutal winter a few years back...
It’s not always straightforward with older houses, but getting the venting and insulation right makes a huge difference in comfort and longevity. Sometimes you’ve gotta improvise a bit, but it pays off in the long run.

- Totally agree on the ridge vent—my attic used to feel like a sauna in July until we added one. Huge difference.
- I’ll admit, I was skeptical about the stainless mesh at first (thought it was overkill), but after a family of raccoons moved in... yeah, worth every penny.
- Underlayment is one of those things I didn’t even know existed until our contractor pointed it out. If you get ice dams, don’t skip it. Trust me, water stains on the ceiling are not a fun surprise.
- Never realized how much airflow matters until I started poking around up there. It’s wild how much trouble a blocked vent can cause.
- Not gonna lie, getting insulation and baffles right took some trial and error. Ended up with a face full of fiberglass more than once, but hey, live and learn.

Here’s how I’d tackle it, step by step: First, strip everything down to the decking—don’t just layer new shingles over old ones. That’s asking for trouble long-term. Next, check the sheathing for rot or soft spots. If you find any, replace those sections before moving on. Underlayment is non-negotiable, especially if you’re in a climate with freeze/thaw cycles. Ice and water shield along the eaves and valleys is a must.
Ventilation’s a big deal, but I’ve seen folks go overboard with ridge vents when their soffit vents are blocked or undersized. Balance is key—too much exhaust without intake doesn’t help. Stainless mesh is smart if critters are an issue, but I’ve had better luck with aluminum in some cases—less rust over time.
Curious if anyone’s tried those newer synthetic underlayments instead of felt? I’ve heard mixed things about durability and walkability during install...

I’ve used synthetic underlayment on two roofs now—one my own, one for a neighbor. It’s lighter and goes down quicker than felt, but it can get slippery if there’s any dew or dust. Durability-wise, I haven’t seen any issues after a few years, but I’d still be careful walking on steep pitches. If you’re aiming for better moisture resistance and less weight, synthetics are worth a look. Just double-check the manufacturer’s install instructions—some brands want specific fasteners or overlaps.
