Aging Roof Before Replacement in Bristol, CT
This front view shows Gina's two-story Bristol home before the roof replacement began. Although much of the roof is obscured from this angle, the visible shingles showed signs of aging and weathering that made replacement a sensible next step.
Worn Three-Tab Shingles on the Existing Roof
An aerial view provides a closer look at the home's aging three-tab asphalt shingles. Gina pursued a roof replacement after learning that the age of the existing roofing system was affecting her ability to obtain a lower homeowners insurance rate.
Algae and Lichen Growth on the Roof
Another aerial view reveals dark algae staining and lichen growth across a section of the roof. Shaded roof surfaces can retain moisture for longer periods, creating favorable conditions for this type of organic growth.
Existing Low-Slope Roofing Before Replacement
A separate lower-level section of the home featured a low-slope roofing system. Although the existing surface appeared relatively intact from above, this area was also included in the complete roof replacement project.
Protecting the Property During Roof Tear-Off
The crew began removing the existing shingles while using large protective tarps around the home. These tarps helped collect debris and protect the surrounding property throughout the tear-off process.
Removing Shingles to Expose the Roof Decking
As the tear-off continued, the crew exposed the underlying roof decking for inspection. Examining the decking is an important step in ensuring that the new roofing system has a suitable foundation.
Inspecting the Existing Roof Decking
With the shingles removed, the crew carefully inspected the exposed decking for signs of damage. Dark material visible near the roof valley was old underlayment adhered to the wood rather than evidence of deteriorated decking.
Existing Chimney Flashing Before Replacement
This view shows the chimney flashing after the surrounding shingles were removed. The existing flashing would be updated as part of the roof replacement to help protect the vulnerable intersection between the chimney and roof.
Removing the Existing Low-Slope Roofing
The crew began tearing off the roofing materials on the home's lower-level roof section. Removing the existing system allowed the team to inspect the underlying structure and prepare the area for new roofing materials.
Exposing the Lower Roof's Plank Decking
With the old low-slope roofing removed, the existing plank decking became visible. The crew identified compromised areas in the surface that needed to be addressed before the new roofing system could be installed.
Installing CDX Plywood Over Existing Plank Decking
New CDX plywood was carefully fitted and installed over the existing plank decking on the lower roof. This created a more uniform surface to support the new low-slope roofing system.
Installing the SBS Modified Bitumen Base Layer
The crew installed an SBS modified bitumen base layer across the prepared lower roof surface. This layer forms part of the multi-layer roofing system designed to provide waterproofing protection on low-slope areas.
Taped Roof Decking Seams and Ice and Water Shield
Back on the main roof, the crew taped the seams between the plywood decking panels and installed ice and water shield in vulnerable areas. These protective measures help reduce the risk of moisture intrusion and provide an additional layer of defense beneath the finished roofing system.
Building a New Chimney Cricket
A crew member constructs a new wooden chimney cricket behind the home's chimney. This small, peaked structure helps divert rainwater and melting snow around the chimney rather than allowing moisture to collect against it, reducing the risk of leaks and water damage.
Preparing the Main Roof for Shingle Installation
Synthetic underlayment was installed across the main roof, along with new drip edge and rake metal. These components help protect the roof decking and direct water away from vulnerable roof edges.
Installing the Polyglass SBS Cap Sheet
The lower roof received its black Polyglass SBS modified bitumen cap sheet. This durable finishing layer completes the primary waterproofing surface of the low-slope roofing system.
Installing Flashing Along the Low-Slope Roof
The crew installed new flashing where the low-slope roof meets the home's exterior wall. The flashing was integrated beneath the siding, which would then be reattached to complete the transition between the roof and wall.
Installing IKO Dynasty Shingles in Granite Black
New IKO Dynasty architectural shingles in Granite Black were installed across the main roof. The dimensional shingles give the home a refreshed appearance while providing durable protection against the elements.
Installing Ridge Ventilation
The crew installed ridge ventilation along the roof's peak to help support attic airflow. Ridge ventilation allows warm, moist air to escape when properly paired with adequate intake ventilation.
Completed Chimney Flashing and Cricket
New chimney flashing was completed, along with a cricket designed to help divert water around the chimney. These details help prevent water from collecting at the chimney's intersection with the roof.
Finished Roof with Ridge Caps and Clean Work Area
A rooftop view shows the completed IKO Dynasty shingles, finished ridge caps, and cleaned work area. The crew completed the final roofing details and removed installation debris from the roof surface.
Completed Roof Replacement in Bristol, CT
A final front view showcases Gina's home following the roof replacement. With new Granite Black architectural shingles on the main roof and a Polyglass SBS roofing system on the lower section, the home has an updated appearance and renewed protection.
