Your first re-roof, in the right order

A lot of West Windsor homeowners are replacing a roof for the first time, on a house built during the township's growth from the late 1970s into the 2000s. The original roof is often builder-grade, and it's reaching the end of its run. Because these roofs are bigger and more complicated than older homes, a few decisions need to be made in the right order, before anything is ordered.

  1. Check your HOA. Many West Windsor developments have associations with approved shingle colors and styles, and some lists have changed since the homes were built. We'll give you product names, colors and spec sheets for the association's review.
  2. Decide on each skylight. Every skylight gets new flashing no matter what. The real question is whether the unit itself should be replaced or removed while the roof is open.
  3. Settle the ventilation plan. Larger homes often have several separate attic spaces. Each one needs its own path for air in and out.
  4. Then pick the shingle. With the constraints known, choosing a color is the easy part.

We order materials only after all four are settled, so there are no surprises on installation day.

Pricing a roof with a lot of edges

Two West Windsor houses with the same square footage can have very different roofs. A simple gable roof is mostly open field. A colonial with hips, several gables, a front porch roof, dormers and a two-story wall above a garage roof has much more detail work, and detail work is where time and material go.

That's why we measure and inspect in person before giving a final number. Our written estimate accounts for:

  • Valleys, each lined with ice and water barrier.
  • Roof-to-wall joints, each with new step flashing and a kick-out flashing at the bottom, so water goes into the gutter rather than behind the siding. On many homes of this era, kick-outs were never installed.
  • Skylights, with a flashing kit or a new unit.
  • Ventilation, including soffit intake and ridge exhaust for each attic section.
  • Decking, with any soft or delaminated sheathing replaced.

Wind, permits and timing in West Windsor

Much of the township is flat and open, with wide fields and big parks like Mercer County Park. Wind has a long run before it reaches a roof. Aging builder shingles that have lost their seal strips are the first to lift. New architectural shingles, correctly nailed and sealed at the starter course and edges, stand up much better. Summer thunderstorms and nor'easters still bring damage, and our storm damage repair crew can document it and meet your adjuster.

On permits: New Jersey has treated re-roofing a detached one- or two-family house as ordinary maintenance since March 2018, so most single-family replacements need no permit. Townhouses and condos generally do. Cutting a new skylight opening changes the framing and generally needs one too, while replacing a skylight in the same opening is a different question. We'll tell you which applies, and when a permit is needed, we pull it through the Division of Code Enforcement & Construction and its online SDL portal.

Spring and fall fill up quickly when whole streets reach the same age, so book early. Every new roof carries a lifetime manufacturer's warranty and a 10-year workmanship warranty. If your roof still has good years left, a targeted roof repair might be enough. Learn more about our roof replacement service and skylights.

Roof Replacement in West Windsor: FAQs

How do I know if my original West Windsor roof needs replacing?

+
Look for curling or cracked shingles, bald spots, granules collecting in the gutters, tabs missing after windy nights and stains below valleys or skylights. If the roof is original and more than 20 years old, a free inspection will tell you whether you have a few good years left or should start planning a replacement.

Should I replace my skylights with the new roof?

+
If a skylight is old, fogged between the panes or leaking at the frame, replacing it while the roof is open costs much less than cutting into a new roof later. If it's in good shape, a new flashing kit is enough. Some owners choose to remove a skylight altogether, and we can deck over the opening.

Do I need a permit for a new roof in West Windsor?

+
Not for a detached single-family home, which New Jersey treats as ordinary maintenance. Townhouses and condos generally need a permit, and so does cutting a new skylight opening. We confirm what your project needs and pull any permit through the Division of Code Enforcement & Construction.

What is kick-out flashing, and do I need it?

+
It's a small bent piece of metal at the bottom of a roof-to-wall joint that directs water into the gutter instead of down the wall. Without it, water can run behind the siding and rot the sheathing. Many homes built in the 1980s and 1990s lack it, so we add it at every joint during a replacement.

How long does it take to replace a larger roof?

+
Many single-family homes take one to two days, but larger or more complicated West Windsor roofs can take longer, especially with skylight replacements or extensive decking repair. We give you a realistic schedule with your estimate and plan around the weather. Call (609) 477-0487 to set up a free estimate.
