Had the same debate on my last roof—synthetic vs. felt. I’ll admit, synthetic was a pain to walk on early mornings, especially with dew. Nearly slipped a couple times. What I ended up doing was using felt for the steeper sections where footing mattered more, and synthetic on the flatter spots that took longer to finish. Not sure if it’s “by the book,” but it worked for me and kept things moving without too many surprises. If you’re not in a hurry, felt’s definitely less nerve-wracking underfoot.
I hear you on the synthetic being slick—had a guy on my crew take a tumble a couple years back when the morning dew hit. Ever since, I’ve been a bit skeptical of using it on anything steeper than a 6/12 pitch. Felt’s not perfect, but at least you know what you’re getting underfoot. The mix-and-match approach isn’t exactly what the manufacturers suggest, but honestly, I’ve seen worse shortcuts on job sites. If you’re budgeting for CertainTeed, just keep in mind their warranty likes to see everything “by the book.” Sometimes it’s worth spending a little extra up front to avoid headaches if you ever need to make a claim.
Yeah, I hear you on the slickness of synthetic—seen a few close calls myself, especially on those steeper pitches when there’s even a hint of moisture. Felt’s got its own headaches, but at least you know what to expect when you step out. The “by the book” thing with CertainTeed is real, though. Had a buddy try to save a few bucks mixing brands and it came back to bite him during a claim. Sometimes it feels like overkill, but if you’re already shelling out for CertainTeed, might as well keep the warranty folks happy.
- Mixing brands to save a few bucks? Been there, regretted it. Warranty folks are like bloodhounds for that stuff.
- Synthetic underlayment is slick as heck—almost lost my footing last fall. Felt’s not perfect, but at least you know when it’s sketchy.
- CertainTeed’s “by the book” thing is a pain, but honestly, if you’re paying for the name, might as well keep the paperwork clean.
- Budget-wise, don’t forget the little extras—drip edge, ice & water shield, all those bits add up fast.
- If you’re in a windy spot, maybe spring for the upgraded starter strip. Lost a few tabs on my last job and had to eat the cost... not fun.
Mixing brands to save cash always looks good on paper, but yeah, those warranty folks know every trick in the book. Had a homeowner try to sneak in a different ice & water shield once—denied faster than you can blink. I hear you on synthetic underlayment too. Slid halfway down a 10/12 last spring and just about needed new pants. For windy areas, upgraded starter strip is worth every penny... lost a whole row of tabs during a nor’easter a few years back and the call-backs were brutal. Don’t skimp on the little stuff—flashing, vents, all that adds up, but skipping it costs way more in the long run.
