"don't skimp on flashing around chimneys or skylights."
Yeah, flashing is critical—seen plenty of roofs fail prematurely because someone cut corners there. Curious though, anyone here have thoughts on ridge vents vs box vents for CertainTeed shingles? I've heard mixed things from different roofers, and honestly, I'm still skeptical if one really outperforms the other in the long run...
Totally agree on the flashing—learned that lesson the hard way myself after a surprise indoor waterfall (not as relaxing as it sounds, trust me). As for ridge vs box vents, I've had both. Ridge vents seem to give a cleaner look and more even airflow, especially if your attic's layout is tricky. Box vents are fine too, but placement matters a lot more. Honestly, either works if installed right...just don't cheap out on ventilation, or you'll bake your shingles from underneath.
When budgeting for a CertainTeed roof, ventilation definitely deserves attention, but don't overlook underlayment and ice/water shield either. I've seen plenty of folks skimp on those, thinking shingles alone will do the job, only to regret it later when leaks show up.
Step one, figure out your square footage and add about 10-15% extra material for waste and cuts—trust me, you'll need it. Next, factor in flashing and drip edge; they're cheap compared to the headache of water damage repairs. Ridge vents are great, as mentioned above, especially if your attic's layout is complicated or if aesthetics matter. But box vents can save you a little cash if placed correctly—just make sure whoever installs them knows exactly what they're doing.
Also, don't forget labor costs. Get multiple quotes and don't automatically go with the cheapest. Ask specifically about warranty coverage, both from CertainTeed and the contractor. A solid warranty can save your bacon down the line if something goes sideways...and believe me, sometimes it does.
Good points overall, but I'd also suggest setting aside a bit extra for unexpected repairs once the old shingles come off.
"Get multiple quotes and don't automatically go with the cheapest."
Exactly this—cheap can get expensive real fast if corners are cut.
When we did ours, the contractor discovered some rotted plywood underneath—definitely wasn't expecting that. Ended up adding a few hundred bucks to our bill. Setting aside extra is smart advice.
Quick question though, has anyone here actually noticed significant differences between CertainTeed's different shingle lines (like Landmark vs Landmark Pro)? Wondering if it's worth the upgrade or mostly marketing hype...
