Commercial Roof Replacement Montville, NJ
A commercial roofer in Montville can replace an aging roof on a warehouse, office, store or apartment building with a new membrane, metal or modified bitumen system, phased so the building stays open and dry. Dial (862) 420-3039 to talk through a roof replacement with a local roofer.
Most commercial roofs reach replacement when leaks spread, the membrane wears out or the insulation gets wet across large areas. A roof with many failing seams, cracking or blistering across the surface, or large wet areas under the membrane is a replacement candidate. Age matters too, since most low-slope systems last somewhere in the range of 15 to 30 years.
Planning starts with what is already on the building. Codes typically cap buildings at two roof systems, so the core cut determines whether a recover is allowed. A recover over one dry roof can skip the tear-off, but wet insulation should always come out. Current energy codes often call for more insulation than the old roof had, which affects edge heights and curbs.
Replacing a roof over an operating building takes coordination. Each section is closed up before the crew leaves, so open roof never sits exposed overnight. Noise, crane lifts, parking, odors near air intakes and protection of the space below are planned with the owner or manager.
Depending on what the roofer finds, commercial roof replacement in Montville, NJ can go hand in hand with commercial roofing and tpo roofing.

The commercial roof replacement process
Here is how a typical commercial roof replacement runs.
Take core cuts
The roofer takes core cuts, runs an infrared or capacitance moisture survey and inspects the deck, drains and equipment. That survey sets the scope.
Choose the system
The membrane or metal system is matched to the building. Tapered insulation and crickets are designed to eliminate ponding. A replacement is the best chance to add a drain or scupper where water has always collected.
Set the schedule
Permits, crane days, staging areas and tenant notices are arranged. Rooftop units may need to be disconnected and lifted, or curbs raised for the new roof height. Tenants get notice of crane days, parking changes and the noisiest phases of the work.
Open the roof in phases
Old roof is removed one section at a time, with deck repairs as needed. Any soft or rusted deck is replaced. Old drains and the bases of curbs are where rusted or rotted deck is most often found.
Build the new system
The new system goes on in layers, sealed at each seam. Each section is tied into the old roof at day end with a temporary seal. Each morning the seal is removed and the work picks up where it stopped.
Flash the details
Curbs, penetrations, drains, walls, scuppers and edge metal are flashed and finished. Closeout includes a final inspection and records for the building.

Commercial Roof Installation Montville, NJ
Commercial roof installation on a new building starts with the design: deck type, insulation, slope, drains and the membrane or metal system. Coordination with the general contractor and mechanical trades makes sure curbs and penetrations are ready for flashing. Good drainage design at installation saves trouble later.
For Montville buildings getting an addition, the new roof has to tie into the old one cleanly. Where new meets old, compatible materials and good flashing matter most. Expansion joints may be needed where buildings meet.

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. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Montville, NJ have the roof checked in the fall and again after the snow melts.

Commercial Roof Replacement FAQ
What permits does a commercial roof replacement require?
Most jurisdictions require a building permit for a commercial roof replacement. Inspectors check layer limits, insulation and attachment. The roofer typically handles the permit and inspections.
Can the business stay open during a roof replacement?
Most commercial roof replacements are done with the building open. Crews work in sections, seal each one daily and plan noisy or smelly work carefully. Air intakes are protected near adhesive work, and spaces below may be covered.
How long does a commercial roof replacement take?
Several factors set the schedule: roof size, tear-off, weather and logistics. Smaller roofs go quickly, and big roofs or campuses take much longer. Expect some weather delays, since open sections must stay dry.
Can a new commercial roof go over the old one?
The existing layers and moisture decide. One dry existing roof can be recovered in many cases. Wet insulation or two layers mean tear-off.
What roof system is best for a commercial building?
The right system depends on the building, its use and what the roof is exposed to. TPO and PVC offer welded seams, EPDM is flexible and proven, mod bit handles traffic and metal suits sloped roofs. The roofer recommends a system after the survey.
