Roof Replacement Work
A Complete Walkthrough — From First Call to Northampton Township Permit Close-Out
Understanding how roof replacement works in Churchville PA is especially important for estate home and historic farmhouse owners, because the process on a 60-square multi-plane roofline with specialty material sections and complex flashing work is meaningfully different from a standard two-day suburban replacement job — and contractors who explain it as if it weren’t are setting you up for surprises.

Step 1 — Free Inspection and Assessment (60–120 Minutes)
A proper assessment of a Churchville estate home is not a quick driveway walkthrough. It involves walking every accessible roof plane, checking all valleys for debris accumulation and the condition of the decking beneath, inspecting all chimney flashings, assessing every dormer transition, and conducting an attic walkthrough to evaluate the framing and decking from below. On a complex roofline, this takes 90–120 minutes to do properly. All Paragon Exterior inspections are free and include written findings before any contract discussions.
Step 2 — Material Selection and Written Estimate (Days 1–3)
The written estimate for a Churchville estate home specifies every material by brand and grade, includes a decking-replacement contingency with per-sheet pricing, documents the full flashing-replacement plan at all penetrations, identifies the Northampton Township permit fee, and states warranty terms — both materials and workmanship — before any deposit is taken. For historic farmhouses with slate or cedar sections, the estimate addresses each material zone specifically.
Step 3 — Northampton Township Permit Application (5–10 Business Days)
Churchville falls under Northampton Township jurisdiction — not Bucks County, not a borough permit office. Full roof replacements require a Northampton Township building permit. Paragon Exterior handles the application entirely. You don’t interact with the township permit office. We apply, schedule the required inspection, and close it out at project completion. Skipping the permit is not a time-saving option — it creates code violations, voids warranties, and can surface at resale as an unresolved permit issue.
Step 4 — Property Protection and Site Setup
Before the tear-off begins, tarps cover all landscaping and plantings in the debris fall zone. The dumpster is positioned on the driveway or in a permitted street location if needed. Ground-level windows and skylights in the fall zone are identified and protected. On estate properties with long driveways or extensive landscaping, site setup takes longer than on a standard suburban property. Paragon coordinates placement with each homeowner before the crew arrives.

Step 5 — Tear-Off and Full Decking Inspection
All existing roofing is removed to bare decking. This is the most revealing phase. Every square foot of decking is walked and probed — soft sections, deteriorated valley framing, and substrate issues are photographed and documented here before any repair begins. On Churchville wooded-lot properties, valley sections, and the decking beneath them are where the most common hidden damage is found. A properly quoted project includes a decking-replacement contingency so the crew can address what’s found without stopping work to place a new material order.
Step 6 — Decking and Valley Repairs
Compromised decking is replaced with matching OSB or plywood. Valley sections are rebuilt from the substrate up — new framing lumber where needed, new decking, and new valley metal. On Churchville properties with a history of debris accumulation, the valley framing beneath the decking is inspected for moisture damage extending beyond the decking layer.
Step 7 — Underlayment and Ice and Water Shield
Ice and water shield covers the first four to five feet from every eave (extended to five feet on steep-pitch sections common on Churchville estates), all valleys, and all penetrations. Synthetic underlayment covers the remaining deck area. This layered water barrier system is what the Northampton Township building code requires and what manufacturer warranties mandate for activation.
Step 8 — Shingle, Flashing, and Ridge Cap Installation
Shingles install from the bottom upward with offset courses. Step flashing at every penetration is interleaved with the shingle courses. Chimney flashings are replaced where required. Hip ridges and dormer-to-main-roof transitions — the most complex details on a Churchville estate roofline — receive careful hand-fitting to ensure water-tight integration at every transition. Ridge cap closes the peak.
Step 9 — Final Inspection, Cleanup, and Permit Close-Out
A magnetic roller sweeps the entire driveway and all ground areas to remove nails. The completed roof is inspected from ground level, with photographs taken. The Northampton Township building inspector schedules and performs the final inspection. You receive written documentation of the completed permit, GAF warranty registration, and the workmanship warranty.
Tips for Churchville Homeowners
Be available on the morning of Day 1 for any questions that arise during the initial tear-off. Clear the driveway and any areas beneath drip edges before the crew arrives. If you have mature plantings against the foundation below roof edges, flag them — the crew will protect them, but identifying them in advance speeds the setup. Call (215) 799-7663 with any questions before, during, or after your project.
