OUR PROCESS

From call to clean-up

Step 1 — Schedule Your Free Evaluation Call 845-448-9411 or fill out the form. We respond the same business day and book your on-site inspection.

Step 2 — On-Site Inspection and Written Estimate George or a senior crew lead inspects your roof, shows you shingle samples, and presents a detailed written proposal with no hidden costs.

Step 3 — Installation Day Our crew strips the old roof, inspects the decking, replaces any rotted boards, installs ice-and-water shield, and lays your new GAF system.

Step 4 — Final Walkthrough and Warranty Activation We walk the finished roof with you, clean up every nail and scrap, and activate your GAF warranty before we leave the property.

WHAT’S INCLUDED

Roof replacement services we offer in the Hudson Valley

Sub-service 1 — Full Tear-Off and Replacement Complete removal of old shingles, inspection of decking, and installation of a new GAF system from drip edge to ridge cap.

Sub-service 2 — Decking Repair and Replacement Rotted or water-damaged plywood is cut out and replaced with new CDX sheathing before any shingles go down.

Sub-service 3 — Ice and Water Shield Installation Required at eaves, valleys, and around penetrations. We install it to code and beyond, because Hudson Valley ice dams demand extra protection.

Sub-service 4 — Ridge Vent and Attic Ventilation Proper intake and exhaust ventilation extends shingle life and prevents moisture buildup that causes mold in Dutchess County attics.

Sub-service 5 — Skylight Reflashing Existing skylights are reflashed with new step and counter flashing during every replacement. No extra charge for standard Velux units.

Sub-service 6 — Soffit and Fascia Repair Damaged trim boards are replaced before new gutters or drip edge are installed, so water does not get behind the system.

Sub-service 7 — Gutter Replacement and Integration Seamless aluminum gutters sized for Dutchess County rainfall, installed same day as your new roof for a watertight connection.

Sub-service 8 — Emergency Tarping If your roof fails before your replacement date, we tarp the exposed area within 24 hours at no charge for booked jobs.
