Trying to budget out a CertainTeed roof - any tips?

“double-check what’s included in writing - cleanup, haul-away, even nails in the yard. All those “extras” add up fast.”

Couldn’t agree more about the fine print. One thing I’d add - when you’re budgeting for CertainTeed or any brand, break out every line: materials, labor, tear-off, wood replacement (per sheet), and disposal. I’ve seen contracts where “minor repairs” turn into a big bill. If your contractor balks at documenting rot or sending photos, that’s a red flag. Midwest weather is unpredictable for sure, but try to pin down a start date and ask how rain delays are handled cost-wise. That saved me some headaches last spring when storms hit mid-project.

That’s a good point about the “minor repairs” line - my uncle got burned on that a couple years back. His estimate looked solid, but once they started tearing off, suddenly there was “hidden rot” everywhere and the price shot up. They did send photos, but it was after the fact, so not much he could do. Has anyone had luck getting a fixed price for wood replacement, or is it always just “per sheet as needed”? I’m curious if that’s negotiable or just standard practice.

That “minor repairs” line is a classic headache. I’ve seen it catch folks off guard more times than I can count. The thing is, until you actually pull those shingles up, there’s just no way to know what’s lurking underneath - especially on older homes or places that have had a few leaks over the years. I get why people feel burned when the price jumps, even with photos after the fact. It feels like you’re stuck.

Now, about getting a fixed price for wood replacement - honestly, it’s pretty rare in my experience. Most roofers (myself included) will quote “per sheet as needed” for plywood or OSB because the amount of rot or damage is just too unpredictable. I’ve had jobs where we thought we’d need maybe two sheets and ended up replacing half the deck. Other times, it looked rough from below but was solid once we got up there.

That said, I’ve seen some homeowners negotiate a cap or at least get a ballpark range written into the contract. Like, “not to exceed X sheets without prior approval.” It’s not standard practice everywhere, but if you’re worried about budget surprises, it doesn’t hurt to ask. Some contractors are open to it if they think the risk is low.

One thing I always recommend: ask for photos before any wood gets replaced and make sure you see them before they start charging extra. A reputable crew should be willing to pause and show you what they found - especially if you’re on-site or reachable by phone.

If your roof’s got a lot of age or history of leaks, maybe budget a little extra just in case. But yeah, that “hidden rot” line item is one of those necessary evils in roofing... nobody likes it, but sometimes there’s just no way around it unless you want to gamble with skipping repairs.

Curious if anyone here has actually gotten a true fixed price deal on decking? I haven’t seen it much except on new builds or full tear-downs where everything’s exposed from the start.

I’ve seen plenty of contracts where “minor repairs” turned into a major wallet drain, especially on homes older than 30 years. Folks are always surprised, but honestly, you can’t tell what’s going on under those shingles until you’re in the thick of it. I’ve had clients swear their decking was fine, only for us to find whole sections rotted out from some slow leak nobody noticed. I do wish more contractors would offer a not-to-exceed clause, but I get why they’re hesitant - it’s a gamble for both sides. Best advice I can give is to budget for the worst, hope for the best, and get as many photos as you can during the tear-off.

That’s solid advice - photos saved my bacon when a previous roofer tried to claim my decking was “all bad.” Turned out only a couple spots were sketchy. If you’re going CertainTeed, I’d also ask about their recycling program for old shingles (not every contractor bothers). Might cost a smidge more but feels better than dumping it all in a landfill. Just my two cents.

Had the same thing happen here - funny how “all bad” turns into “just a couple boards” when you’ve got pics. I’m with you on the recycling too. A little extra cost, but less landfill guilt.

Photos really do keep things honest. I’ve seen way too many “full deck replacements” turn into a handful of bad spots once there’s proof. And yeah, recycling the tear-off isn’t cheap, but it’s worth it - less mess in the landfill, and clients appreciate the effort.

I get the whole “full deck replacement” thing - seems like every roofer wants to go straight to that, and it’s a huge chunk of change. When I got quotes for my CertainTeed roof last year, one guy swore half my deck was rotted, but when I crawled up there myself (not fun, by the way), I found maybe three bad spots. Photos definitely helped keep things honest - once I asked for proof, the story changed real quick.

About recycling the tear-off… I’m kinda torn. I get that it’s better for the environment, but the extra fee wasn’t small. I ended up skipping it because my budget was already stretched thin. Maybe if you’re not pinching pennies as hard as I was, it’s worth it for peace of mind. My neighbor did pay for recycling and said her contractor actually showed her where the shingles went, which was cool, but honestly, I just wanted to get the job done without going overboard.

If you’re trying to budget this out, watch for all those little “extras” in the quote - decking replacement, disposal fees, ice & water shield upgrades. They add up fast. I had one company try to sneak in a $900 “permit processing fee,” which seemed nuts. Also, CertainTeed has a bunch of shingle lines - Landmark was cheaper than I expected, but the higher-end stuff jumped up quick. If you don’t care about color or style as much, sticking with their basic line saved me a few bucks per square.

One thing I wish I’d done: ask for line-item pricing on everything. That way you can see if they’re padding labor or materials. And if you can swing it, get a second opinion on the deck before agreeing to replace the whole thing. Sometimes it really is just a couple bad boards.

Anyway, hope that helps a bit. Roofing is one of those things where you feel like you’re always guessing what’s legit and what’s just upsell...

- Agree on getting line-item pricing - makes it way easier to spot where they’re trying to sneak in extra costs.

Curious how folks are handling ice & water shield upgrades? In my area, some contractors push for full coverage even when code only calls for 3 feet at eaves. Anyone actually see value in paying for more?

Ice & water shield is one of those things where more isn’t always better. Around here (Midwest), code is 3 feet up from the eaves and that’s plenty unless you’ve got a really low slope or a history of ice damming. Full coverage can get pricey fast, and honestly, I see more issues from poor attic ventilation than from not enough shield. I’d save the extra cash unless your roof’s a special case.

Couldn’t agree more about ventilation being a bigger headache. I’ve seen folks spend a ton on ice & water, then still end up with condensation problems because their attic’s basically a sauna. Unless you’re dealing with a crazy low pitch or a spot that’s notorious for ice dams, 3 feet up from the eaves is usually plenty. If you’re trying to stretch the budget, I’d focus on good vents and maybe beef up insulation before going all-in on shield. CertainTeed’s underlayments are solid, but you don’t need to go overboard unless your roof’s got some weird quirks.

I’ve seen folks spend a ton on ice & water, then still end up with condensation problems because their attic’s basically a sauna.

This is so true. I’m in a pretty mild climate, and honestly, the only time I’ve seen full ice & water pay off is on those north-facing slopes that never see sun or when someone’s got a super low pitch. Otherwise, it just feels like overkill. Good vents and some extra cellulose up top have made way more difference for me than stacking up layers of underlayment. Plus, less plastic waste, which I’m all about.

I get where you’re coming from - overdoing the ice & water shield can feel like tossing money at a problem that’s really about airflow. But I’m not totally convinced it’s just overkill in most cases. Maybe it’s because I’ve seen a few too many “mild climate” winters turn into freeze-thaw nightmares, especially with those weird cold snaps we’ve been getting lately. Had a neighbor who thought his attic was dialed in, but after a freak storm, water snuck in at the eaves and made a mess. He’d skimped on the ice & water, figuring it was unnecessary for our area.

That said, I’m all for dialing back on plastic where it makes sense. But I do wonder - are you sure your cellulose is staying dry up there? I’ve heard stories about insulation getting soggy from minor leaks that go unnoticed for ages, and then you’re dealing with mold or worse. Maybe it’s just paranoia from seeing too many botched jobs, but sometimes that extra layer of protection feels like cheap insurance.

I’m curious if anyone’s tried some of the newer eco-friendly underlayments? I’ve seen recycled-content options that claim to cut down on plastic waste but still give you a solid barrier. Not sure how they hold up long-term, though.

And yeah, venting is huge. I went with ridge vents and solar fans on my last place, and it made a massive difference - barely any condensation even in the weirdest weather. Still, I can’t shake the feeling that skipping ice & water entirely is rolling the dice, especially if your roof’s got any tricky spots or valleys.

Guess it comes down to how much risk you’re willing to take versus the upfront cost and environmental impact. There’s no perfect answer, but I’d rather have a little extra peace of mind than deal with hidden water damage down the line...

I hear you on the “cheap insurance” angle. I used to think ice & water shield was just a way for roofers to pad the bill, but then my cousin’s place got hit with one of those freak March storms - ice dammed up, water snuck in, and suddenly he’s got a science experiment growing in his attic. He’d only put the shield at the eaves, not the valleys, because “that’s what everyone does around here.” Now he’s a convert.

I’m with you on not wanting to wrap the whole house in plastic, though. I tried one of those recycled underlayments last year - think it was GAF Deck-Armor or something similar. It went down easy and didn’t have that weird chemical smell. No leaks so far, but it’s only been through one winter, so who knows long-term.

Venting is a game changer. I added a ridge vent and some extra soffit vents when I redid my roof, and it actually made the upstairs less stuffy in summer too. Still, if your roof has any weird angles or dormers, I’d rather spend a bit more up front than risk tearing out soggy insulation later. Peace of mind is worth a few extra bucks... or at least that’s what I tell myself when I see the bill.

Yeah, I totally get the hesitation on “wrapping the house in plastic” - I’m always looking for greener options too. Deck-Armor’s been holding up fine for me, but I’m only two years in. And you nailed it with venting. It’s wild how much difference a ridge vent makes, especially with those weird rooflines. Spending a bit more up front stings, but man, it beats moldy insulation or having to redo anything. Peace of mind’s worth it, even if my wallet disagrees.

Deck-Armor’s a solid pick for underlayment, especially if you’re worried about breathability. I’ve seen it hold up in some tough spots, but honestly, it’s not a cure-all - if your ventilation isn’t dialed in, even the best materials will run into trouble over time. Ridge vents are a game changer, but with complex rooflines, sometimes you still get dead spots. I usually suggest running a smoke test before finalizing vent placement…sounds silly, but it can save you grief down the line. The upfront cost hurts, yeah, but fixing mold or rot later is way worse for the budget.

That’s spot on about ventilation being just as important as the underlayment. I went with Deck-Armor on a reroof about five years ago, and while it’s definitely more breathable than traditional felt, I noticed the attic still ran hot until I tweaked the venting. Ridge vents helped, but my roof’s got a couple valleys and dormers that made airflow tricky. Ended up adding a couple of low-profile intake vents near those dead zones - wasn’t cheap, but it finally balanced things out.

The smoke test is a great idea. I did something similar with incense sticks (my contractor thought I was nuts), but it actually showed where the air just wasn’t moving. Caught a couple spots we’d have missed otherwise.

If you’re budgeting for CertainTeed, don’t overlook flashing and ice/water shield either. Those add up fast, especially if you’re in a colder climate or have a lot of roof edges. I learned the hard way that skimping there just means more headaches later... It’s all about spending a little more upfront to avoid way bigger repair bills down the road.

- Ran into the same thing with attic heat, even after putting in a “breathable” underlayment (I used CertainTeed DiamondDeck). Ridge vent helped, but the real game changer was adding more soffit vents.
- My house is older, so the original builder barely put in any intake. Once I drilled a few more holes and added vent covers, temps dropped noticeably.
- Agree on not skimping on flashing - my first roof job I tried to save by reusing some old stuff. Ended up with leaks around the chimney two winters later. Had to pay for repairs and redo the flashing anyway.
- Ice/water shield is pricey, but in my area (upstate NY), it’s non-negotiable. Ice dams are brutal here.
- One thing I’d add: budget for extra nails and starter shingles. I underestimated both, and it meant an extra trip to the store mid-project.
- If you’re doing valleys, consider the “open metal valley” method. Costs a bit more, but I’ve had less trouble with debris and leaks since switching.
- All in, I’d say don’t cut corners on anything that keeps water out. The rest is mostly cosmetic.

Funny you mention the soffit vents - I've lost count of how many attic inspections I’ve done where folks swear they have “good ventilation,” but it’s all ridge vent and barely any intake. It’s like putting a straw in a bottle with the cap on… air’s not going anywhere. The difference after folks add more soffit vents is almost immediate, especially in these older places where insulation and airflow weren’t top priorities back when.

I’ll second the point about not reusing flashing. I had a seller last year who insisted the old stuff was “just fine” because it looked okay from the ground. Come first big rain, water was sneaking in behind the bricks. Ended up costing them more than a fresh piece of flashing would’ve - plus a chunk of drywall repair. Sometimes saving a couple bucks up front just isn’t worth the headache.

On ice/water shield, I’ve seen houses up here try to get away with the bare minimum and, sure enough, you see those telltale stains inside come spring. If you’re in upstate NY, I’d say don’t gamble with it. Same goes for starter shingles. I get why folks try to cut corners, but every “shortcut” seems to turn into a call-back or a repair bill down the line.

One thing I’m curious about - has anyone run into issues with CertainTeed’s DiamondDeck getting a little too slick during install? Had a crew complain about footing last year, but I haven’t seen it myself. Wondering if that’s just an installer gripe or an actual safety concern. Also, for folks who’ve done open metal valleys: do you notice much extra noise during rain? I’ve always wondered if that’s something homeowners regret after the fact, or if it’s just a non-issue once everything’s sealed up.

Curious what others have run into with these details. Sometimes it feels like every house has its own set of “gotchas” no matter how much you plan.

I’ve got a pretty old house (built in the 50s) and when we did our roof last year, I was surprised how much the venting stuff mattered. I always thought “a vent’s a vent,” but turns out, not so much. We had almost no soffit intake - just a ridge vent - and the attic was basically an oven. After adding more soffit vents, it actually felt cooler up there, which I didn’t expect to notice that fast.

About DiamondDeck being slick, my roofer mentioned it too. He said it was especially bad on a damp morning - almost like walking on ice. They ended up laying down some old mats for footing until things dried out. He didn’t seem mad about it, just said you have to be careful and maybe not rush if there’s dew.

On the open metal valleys, I was worried about rain noise too but honestly, I haven’t noticed anything inside. Maybe if you’re right under the valley in a quiet room you’d hear something, but with insulation and drywall, it’s not obvious. The bigger “gotcha” for us was how much flashing and underlayment add to the price, but skipping them just didn’t seem worth the risk.
