Spray Foam Roofing Parsippany, NJ
Spray foam roofing in Parsippany is a layer of closed-cell polyurethane foam sprayed onto the roof and covered with a silicone or acrylic topcoat, which adds real insulation value along with waterproofing. Dial (862) 693-4349 to talk through a spray foam roof with a local roofer.
Spray foam roofing begins as two chemicals mixed at the gun, which react and expand into a hard, closed-cell layer. With no seams or laps, it flows around pipes, curbs and odd shapes without separate flashing pieces. Since it can be sprayed thicker in some areas, it can correct ponding while it insulates.
The weak point of foam is UV exposure. Ultraviolet light breaks down exposed foam, so it is always covered with a coating, usually silicone or acrylic, sometimes with granules for traffic areas. As long as the coating is renewed before foam is exposed, the roof can keep going for a very long time.
It helps to know what kind of roof you have before you call. Tell the roofer what the current roof is made of, where water stands and where it has leaked. For an existing foam roof, mention when it was last coated and whether you see brown or orange foam showing through.
Spray Foam Roofing is often paired with roof coating and commercial roof coating, depending on the cause.

How a spray foam roof is installed
SPF goes on in stages, and weather matters at each one.
Check the existing roof
The roofer checks the deck and existing roof, often with core cuts or an infrared scan to find wet areas. Wet materials are removed, since foam sprayed over moisture can blister.
Prepare the surface
Loose material is removed, the surface is cleaned and primers are applied where needed. Masking and wind limits keep overspray off vehicles and neighboring surfaces.
Apply the SPF
The foam is sprayed in passes, each one adding thickness, until it reaches the planned depth. Moisture, low temperatures and wind all affect the foam, so the crew watches conditions closely.
Check the foam surface
The roofer checks the surface texture and thickness before coating. This is the time to correct thin areas or poor texture.
Seal the surface
A topcoat goes on to the specified mils, often in two coats of different colors to show full coverage. Walk paths can be coated thicker or with granules for durability.
Finish the edges
Drains, scuppers and edges are checked so water leaves the roof and the foam stops cleanly at the perimeter. A gauge confirms the coating is thick enough.

Spray Foam Roof Repair Parsippany, NJ
Most spray foam roof repairs involve cutting out damaged foam and filling it back in with new foam or sealant. Bird pecks, small punctures and hail dents are cleaned and filled with sealant, while larger damaged or wet areas are cut out down to sound foam and resprayed. The repair is then coated to match the rest of the roof.
In Parsippany, many foam roof repairs come after storms or when bare foam has been left exposed for too long. Blisters, where foam has separated from the layer below, are cut open, checked for moisture and refilled. Fixing small damage quickly keeps water from soaking into the foam and spreading.

Spray Foam Roof Coating Parsippany, NJ
The coating on a spray foam roof wears over time and must be renewed periodically. Most foam roofs need a fresh topcoat somewhere in the 10 to 20 year range. Recoating before foam is exposed keeps the job simple.
Before recoating, the roofer cleans the surface, fixes damage and tests how well the new coating sticks. For roofs with standing water, silicone is the usual pick; acrylic works on well-drained roofs. Since new coatings do not stick well to old silicone unless they are silicone too, knowing the existing type matters for any Parsippany recoat.

What the local climate does to a roof
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. 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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Parsippany, NJ have the roof checked in the fall and again after the snow melts.

Spray Foam Roofing FAQ
Can you walk on a spray foam roof?
SPF roofs are rigid and can be walked on for maintenance. Sharp objects, dropped tools and heavy point loads can dent or puncture it, so walkways around equipment are a good idea. A wet coated roof is slick, so stay off in rain or frost.
How long does a spray foam roof last?
A foam roof can last a very long time if the coating is kept up. Coating life varies with thickness and type, often in the 10 to 20 year range. If the coating is neglected, the foam degrades and the roof fails much sooner.
When can spray foam roofing be applied?
Foam can only be sprayed in dry, mild conditions with light wind. Wet surfaces cause poor adhesion and blisters, and wind spreads overspray. Planning around a stretch of dry weather is part of the job.
Can spray foam fix a leaking metal roof?
Foam over metal is one of the most common SPF uses. The foam seals over screws and panel laps and insulates the building at the same time. Rusted areas are cleaned and primed, and loose panels are secured before spraying.
Can spray foam go over an existing roof?
One advantage of SPF is that it can go over many existing roofs. A moisture survey decides which areas stay and which come out. Code limits on roof layers still apply, so the roofer checks what is there.
