Roofing
A new roof, done right
Full roof replacements with GAF Timberline shingles, installed by a GAF Certified contractor. Flat roofs, balconies and repairs too.
GAF Certified
Why it matters for your roof
GAF certifies contractors who are properly licensed and insured and who commit to installing GAF roofing systems the way GAF specifies. Because Diverse Contracting is GAF Certified, your new roof can qualify for GAF's enhanced warranties, which a non-certified roofer can't offer. We'll explain the warranty options for your roof at your estimate.
Every roof replacement includes
Full tear-off
Old shingles and underlayment removed down to the deck; damaged wood replaced.
Leak barrier & underlayment
Ice and water protection at the eaves and valleys, synthetic underlayment over the rest.
Shingles, ridge & vents
GAF starter strips, shingles, ridge cap and ventilation installed as one system.
Flashing & cleanup
New flashing at chimneys and walls, magnetic sweep for nails, and a full cleanup.

Colors on screen are approximate and vary by device. We bring physical samples to every estimate so you can see the real color in daylight against your house.
Flat roofs
Porches, balconies, sunrooms and commercial roofs
Low-slope roofs need a membrane system, not shingles. We re-roof balconies, porch and sunroom roofs, and commercial flat roofs, and we repair flashing around chimneys, skylights and rooftop equipment.
