Protect Your Home with a New Roof

Gemz Construction delivers roofing installation and replacement services throughout Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island for homeowners who need lasting protection.

Your roof takes direct hits from salt air, coastal storms, and seasonal temperature swings that shorten its lifespan across Long Island. When shingles start curling or flat sections develop soft spots, water finds its way into places you cannot see until the damage spreads. Gemz Construction handles roofing installation and replacement for residential properties using asphalt shingle and flat roofing systems built to withstand local weather patterns and deliver decades of performance.


We start with a thorough inspection to assess your current roof condition and identify areas where leaks, ventilation issues, or structural concerns need attention. You receive material recommendations based on your home's design, your budget, and the specific exposure your roof faces. Our crew removes old roofing, installs new underlayment and flashing, and secures your chosen shingles or flat roofing membrane with techniques that prevent wind uplift and water intrusion. We finish with a complete site cleanup that leaves your property free of nails, debris, and packaging materials.


If you need a roof replacement or want to discuss options for your home, reach out to Gemz Construction to schedule an inspection in Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island  .

What happens during a roof replacement

We remove your existing roofing down to the decking, allowing us to inspect the wood substrate for rot, soft spots, or damage that compromises structural integrity. Once repairs are complete, we install synthetic underlayment that resists moisture better than traditional felt, followed by ice and water shield in vulnerable areas like valleys and eaves. Your new shingles or flat roofing membrane go on next, secured with corrosion-resistant fasteners and sealed at every penetration point to block water entry.


After we finish, you will notice your home looks sharper from the street, attic temperatures drop during summer months, and the sound of rain hitting your roof changes from rattling and dripping to a consistent, even noise. Your energy bills often decrease because improved ventilation and reflective roofing materials reduce heat transfer into living spaces.


We match shingle colors to your siding and trim, coordinate work schedules to minimize disruption, and provide warranties that cover both materials and labor. The work typically takes one to three days depending on roof size, pitch, and weather conditions. We do not perform structural framing modifications or install skylights as part of standard replacement jobs, but we can refer trusted partners who handle those additions.

Questions homeowners ask before replacing a roof

Homeowners in Manhattan, Brooklyn, Queens, The Bronx, Staten Island and Long Island  often want to know how long the work takes, what materials suit their home best, and how to prepare their property before the crew arrives.

How long does a roof replacement take?
Most residential roofs take one to three days to complete, depending on size, pitch, and weather. We schedule work to avoid rainy periods and coordinate closely with you on timing.
What roofing materials work best for coastal homes?
Asphalt shingles with high wind ratings and flat roofing membranes designed for UV resistance and drainage hold up well against salt air and storm exposure. We recommend products that meet or exceed local building codes for wind uplift and fire resistance.
What should I do to prepare my home before roofing work starts?
Move vehicles out of the driveway, cover items in your attic with tarps, and secure outdoor furniture or decorations that could be damaged by falling debris. We handle the rest, including protecting landscaping near the house.
Why do some roofs fail early?
Poor ventilation traps heat and moisture in the attic, which accelerates shingle aging and promotes wood rot. Incorrect flashing installation around chimneys and vents also allows water to seep under roofing materials, causing leaks that spread unseen until interior damage appears.
When should I replace my roof instead of repairing it?
If your roof is over twenty years old, shows widespread shingle damage, or has multiple leak points, replacement usually costs less over time than repeated repairs. We inspect your roof and provide honest guidance on whether repair or replacement makes sense for your situation.
