Skylight Installation Mahwah, NJ
A roofing contractor in Mahwah can add fixed or venting skylights to most pitched roofs, with a proper flashing kit so the opening stays dry, and help you choose between a fixed unit, a venting unit or a tube. One call to (551) 351-0251 reaches a nearby roofer who handles skylight installation.
Skylights earn a reputation for leaking because of poor installation, not because of the units themselves. A new skylight goes into a framed opening, gets wrapped with self-adhered membrane and then flashed with step, head and sill pieces tied into the shingles. Below the roof, a light shaft runs through the attic to the ceiling, and that shaft is framed, insulated and drywalled.
Before installation, it helps to know the main options. Venting skylights help in bathrooms and kitchens, and fixed units work anywhere you just want light. Where the attic is cramped or the room is small, a tubular skylight delivers daylight through a narrow reflective tube.
A few details help plan the project. Write down the room, the rough spot on the ceiling and whether you want ventilation as well as light. Mention the age of the roof too, since installing a skylight just before a reroof means flashing it twice.
Many skylight installation calls in Mahwah also turn up a need for skylight repair or roof installation.

What happens during a skylight installation
The work happens in a set order, from layout to the finished ceiling.
Check the attic
The roofer checks the rafter spacing, the attic space, wiring and ductwork, then picks a size and spot that lines up with the room below. Sizing to the rafter bay keeps the framing simple.
Open the deck
If a rafter has to be cut, it is tied into doubled headers and doubled rafters on each side. The opening is framed square so the unit seats evenly.
Set the skylight
The unit goes in according to its type, either straight onto the deck or onto a framed curb. Self-adhered membrane is wrapped up the sides of the frame before flashing.
Install the flashing kit
The sill flashing goes on first, then step flashing is woven in with each course of shingles up the sides, and the head flashing goes on last. The order of the flashing is what keeps the skylight from leaking.
Finish the ceiling
A light well is built from the skylight to the ceiling, insulated well to limit heat loss and condensation. Flaring the shaft spreads light across more of the room.

Skylight Replacement Mahwah, NJ
When a skylight has fogged glass, a cracked dome, a rotted frame or keeps leaking, replacement is usually the lasting fix. Many replacements fit the same opening, though older curb-mounted domes are often replaced with a modern glass unit sized to the existing curb. The shingles around the unit are removed and replaced, and new membrane goes down before the new flashing.
For Mahwah homes, the best time to replace a skylight is during a reroof. Keeping an aging unit means tearing into new shingles later to replace it. Ask about upgrades such as venting operation and laminated glass when choosing the new unit.

Solar Tube Installation Mahwah, NJ
Tubular skylights are a simple way to light a closet, hallway, laundry room or small bath that a regular skylight cannot reach. The small roof cutout means no rafters are cut and the install is usually far simpler than a full skylight. Angled adapters let the tube route around ducts and framing.
Solar tubes suit many Mahwah homes with long hallways and interior rooms. The dome on the roof is flashed into the shingles the same way any roof penetration is, with the flashing base lapped under the course above. A sleeve of insulation in the attic keeps the tube from sweating in cold weather.

Roofs in this climate
Cold winters bring snow, ice and a long stretch of freezing nights. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, which is how ice dams form and back water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. Most homeowners in Mahwah, NJ have the roof checked in the fall and again after the snow melts.

Common questions about skylight installation
Does a skylight need a permit?
Whether a permit is required depends on the local building department. Structural changes generally need a permit, and the roofer will know what applies. Ask the roofer to confirm local requirements before work begins.
Which way should a skylight face?
The direction the slope faces changes how the skylight performs. North-facing skylights give steady, even light with little heat, while south and west-facing units bring more light and more summer heat. Choosing the slope with the room in mind gives the best result.
Should I get a skylight or a solar tube?
The main difference is size: skylights need a framed shaft, solar tubes need only a narrow tube. Larger rooms and vaulted ceilings are a good match for a skylight. Small rooms with tight attics are where tubes shine.
Should I install a skylight when I replace my roof?
Timing a skylight with a new roof lets everything be flashed together. The skylight and roof then age together and can be serviced together. If a reroof is near, it usually pays to wait and do both at once.
Will a new skylight leak?
Leaks are mostly a sign of poor flashing, not a flaw in skylights. The key is a flashing kit lapped into the shingles from the bottom up, with membrane underneath, instead of a bead of caulk. Ask how the roofer plans to flash the unit before work starts.
