GAF ProStart delivers 120.33 lineal feet of starter strip coverage per bundle at 52 lbs — the kind of product that makes sense when you’re racing Montana’s short construction season. The perforated design splits 19 full sheets into 38 pieces without cutting, which means your crew spends less time with utility knives and more time nailing.
The Real Advantage: Coverage and Labor Savings
ProStart provides up to 50% more coverage per bundle than cutting 3-tab shingles for starter strips. That’s not marketing fluff — it’s simple math. When you’re manually cutting 3-tabs, you’re throwing away material with every cut. ProStart eliminates that waste entirely.
The factory-applied Dura Grip adhesive is positioned specifically to prevent shingle blow-off. Compare that to crews dripping roofing cement by hand — inconsistent placement, messy application, and wasted time. ProStart’s consistent factory-applied adhesive placement beats manual application every time. In Montana’s wind-prone areas, that consistent adhesive line matters.
Labor savings compound across the job. No on-roof cutting means no measuring, no chalk lines for straight cuts, and no cleanup of shingle scraps. Your crew simply splits the perforated sheets and nails them down. The environmental benefit of reducing landfill waste from cut-up shingle scraps is real, but the immediate benefit is less debris blowing around the jobsite.

The high-quality adhesive locks roof edges securely along eaves and rakes — critical protection in Montana where chinook winds test every roof edge. Standard roofing nails (1 inch or longer) handle the fastening, with specific patterns varying by the shingle type you’re installing over it.
Installation and Compatibility
ProStart is compatible with standard English-sized shingles, metric-sized shingles, and GAF Timberline and other GAF shingle families. The universal compatibility means one starter strip SKU handles most jobs.
Installation follows standard practice: apply along eaves and rake edges with the adhesive side down toward the roof edge. The perforated splitting design means no cutting required — just bend and separate along the perforation.
For GAF’s Lifetime Limited Warranty qualification, ProStart must be installed as a starter course at eaves and rakes on single-family detached residences, along with at least 3 qualifying GAF accessories. Smart contractors already install complete systems for warranty coverage — ProStart makes that easier.
Who Should Use ProStart
Worth it for production roofers who value speed and consistency. With approximately 356 reviews averaging 4.7 stars, contractors praise it for saving time and creating professional-looking roof edges.
Skip it if you’re doing a small repair or have leftover 3-tabs you need to use up. The labor savings shine on full roof replacements where every minute counts.
The lower total installed cost due to reduced labor and waste makes the math work for most jobs. Less cutting, less cleanup, less callbacks from inconsistent adhesive application. ProStart does one thing — starter strips — and does it efficiently.
