Roof Ventilation and Flashing Matter as Much as Shingles
Shingles are the visible part of the roof, but water management and airflow are often the details that decide how well the system functions over time. Our proposals consider ventilation and flashing alongside the roof covering.
Balance Intake and Exhaust
Attic ventilation generally relies on a compatible path for air to enter low and leave higher up. Ridge ventilation cannot work as intended if intake is inadequate or blocked, and not every roof design is suited to the same vent type.
Insulation placement, existing vents, roof geometry and local conditions must be assessed before recommending changes. Adding more vents without a system plan can be counterproductive.
Important Flashing Details
Chimneys & Sidewalls
Properly integrated step flashing, counterflashing and transitions around masonry or siding.
Pipe Boots & Penetrations
Roof penetrations need flashing components suited to the pipe and roof system.
Eaves, Rakes & Valleys
Drip edge and appropriate underlayment help direct water away from vulnerable roof edges and intersections.
Questions to Ask a Roofer
Will existing vents be kept, replaced or reconfigured? What is included at chimneys, skylights and pipe penetrations? Are starter shingles and drip edge included at all required edges? What photos will document hidden work?
ARS typically includes property protection, progress photos and cleanup within a complete roof replacement scope. Any special conditions should appear on the written estimate. Review our replacement process before comparing contractors.
Build the Plan Before Installation
Roof ventilation and flashing decisions should be made for the actual home. A qualified field review may identify needs not visible in an online aerial estimate.
If your roof has leaks around a chimney, skylight or other transition, start with roof repair guidance or request an assessment.
Frequently Asked Questions
Do all homes need a new ridge vent?
No. Ventilation design depends on attic intake, exhaust balance, roof geometry and existing conditions.
Why replace pipe boots during reroofing?
Pipe flashing is a common penetration detail. Replacing aged boots while the roof covering is removed can be part of a coordinated roof system scope.
Is drip edge included?
ARS written roof scopes commonly call for drip edge and edge protection as appropriate; confirm the specifics in your proposal.
