Frequently Asked Questions

Yes, GAF Slateline® Shingles feature bold shadow lines and tapered cutouts to create the look of slate in an asphalt shingle at an economical price. They resemble a true stone, slate roof much more closely when you choose either Antique Slate, English Gray, Royal Slate, or Weathered Slate, four beautiful color options available for Slateline® Shingles.

If you’re considering a slate roof but prefer an easier installation and a lighter product, you may also want to consider GAF Camelot® II Shingles for slate-inspired elegance that conjures the romance of European architecture.

Both options are part of the GAF Designer Shingles collection.

 

GAF Slateline® Shingles come in a range of colors, including Antique Slate, English Gray, Royal Slate, and Weathered Slate.

Check out our Virtual Remodeler to get an idea of what each shingle style and color looks like on your home. Please note that picking the right shingle color for your home is important.

For GAF Slateline® Shingles, we recommend GAF TimberTex® Premium Ridge Cap Shingles to add that perfect finishing touch to help protect hips and ridges while accentuating your new GAF roof.

TimberTex® Premium Ridge Cap Shingles are available in all four Slateline® shingle colors: Antique Slate, English Gray, Royal Slate, and Weathered Slate.

 

GAF Slateline® Shingles should use a minimum of 3/8" thick (10 mm) plywood or OSB decking. Do NOT fasten shingles directly to insulation or insulated deck unless authorized in writing by GAF. Roof decks and existing surfacing material must be dry prior to installation of shingles. Learn more about Slateline® installation instructions and the best practices for contractors.

  • Location – The area you live in — its cost of living, climate, local building codes and permit requirements — are variables that also factor into the cost of your new roof.
