FAQs
What is a high-performance roofing underlayment and why is it important?
A high-performance underlayment is a synthetic or rubberized membrane installed directly on the roof deck before shingles or metal panels are applied. It forms a secondary water-shedding barrier that protects your home from wind-driven rain, ice dams, and minor leaks caused by damaged shingles. In Kingston’s four-season climate, this extra layer guards against moisture that can lead to rot, mold, and costly structural repairs, ensuring your roof system meets or exceeds Ontario Building Code requirements.
How does Kingston’s climate affect my choice of underlayment?
Kingston experiences freeze–thaw cycles, lake-effect snow, and strong summer storms off Lake Ontario. These conditions demand an underlayment with superior tear resistance, UV stability, and an ice-and-water shield along eaves and valleys. High-performance synthetics and self-adhering membranes stay flexible in sub-zero temperatures and stay put in high winds, greatly reducing the risk of water intrusion compared to traditional #15 or #30 felt.
Are synthetic underlayments better than traditional felt?
Yes. Quality synthetic underlayments are lighter, 10–20 times stronger, and offer higher water repellency than asphalt-saturated felt. They do not wrinkle when wet, lay flatter for smoother shingle installation, and can be left exposed for weeks without degrading—a valuable feature if weather delays occur. Although felt still meets minimum code, most Kingston-area roofing professionals now recommend synthetics for longer service life and fewer callbacks.
Will a premium underlayment help me qualify for insurance or warranty benefits?
Many shingle manufacturers extend their enhanced system warranties only when an approved high-performance underlayment and matching accessory products are used. Likewise, some insurers offer discounts or deductible reductions for roofing systems with documented ice-and-water shields in ice-prone regions such as eastern Ontario. Always keep installation records and product labels to support any future warranty or insurance claims.
How long does installation take and will it disrupt my daily routine?
For an average 2,000–2,500 sq. ft. Kingston home, removing the old roofing, inspecting the deck, and installing a synthetic underlayment typically takes one day; full shingle replacement may add another day or two. Our crews start after 7 a.m. and finish before dusk, using magnetic sweepers to collect nails and maintaining clear access to entrances whenever possible. Most homeowners remain in the house throughout the process with minimal disruption.
How much more does high-performance underlayment cost, and is it worth it?
Upgrading from felt to a premium synthetic underlayment usually adds $0.20–$0.40 per square foot of roof area—about $250–$450 for a typical Kingston bungalow. Considering it can extend roof life by 5–10 years, lower maintenance costs, and protect interior finishes from leaks, most homeowners find the modest upfront premium delivers strong long-term value.
