FAQs
What is airtight ventilation roofing and why is it important for homes in Jamestown?
Airtight ventilation roofing combines a tightly sealed roof deck with a controlled ventilation layer that exhausts moisture-laden air while preventing uncontrolled air leaks. In Jamestown’s climate—marked by cold, snowy winters and humid summers—this system keeps warm indoor air from escaping in winter, stops summer humidity from entering, and mitigates ice-dam formation. The result is lower energy bills, better indoor air quality, and a longer-lasting roof structure.
How does Roofing Done Right achieve both an airtight seal and proper ventilation?
We install a continuous air barrier (usually a self-adhered membrane) over the roof deck to eliminate gaps and penetrations where air can leak. Above this layer we create a vented air channel using counter-battens and ridge/soffit vents. This dual-layer approach lets moist air and heat escape through the designed pathway while preventing uncontrolled drafts. All penetrations—plumbing vents, skylights, chimneys—are flashed and taped to the membrane for a truly airtight assembly.
What advantages will I notice after upgrading to an airtight ventilation roof?
• Energy savings of 10–25 % because conditioned air isn’t escaping. • Prevention of mold, mildew, and rot by actively removing roof-deck moisture. • Reduced ice dams and icicles, protecting gutters and eaves. • A quieter home thanks to the continuous air barrier that blocks outside noise. • Longer shingle and decking life, which can add 10+ years to roof longevity.
How long does installation take and will I have to leave my home?
A typical single-family residence in Jamestown takes 2–4 days for full tear-off, membrane application, ventilation build-up, and shingle installation. Weather permitting, most projects are completed without exposing the interior to the elements. You can stay in your home throughout; the work is exterior, and we coordinate debris removal to keep driveways and entryways accessible.
Can airtight ventilation roofing be added to my existing roof or do I need a complete replacement?
If your current shingles are near the end of their service life or the decking shows signs of moisture damage, a complete replacement is recommended so we can properly seal the deck. However, on relatively new roofs we can sometimes retrofit the vented over-deck system and add selective membrane sections. A free on-site inspection will determine the most cost-effective path.
What maintenance is required and how long will the system last?
Maintenance is minimal—keep ridge and soffit vents clear of debris and schedule an annual inspection to ensure flashing remains intact. Because the air barrier is protected beneath the roofing, it is not subject to UV damage and should last 30–40 years. Asphalt shingles or metal panels installed above it will follow their standard life expectancy, but the enhanced drying capability often extends that by 5–10 years.
