Frequently Asked Questions

Roofs need inspection twice yearly, ideally in spring and fall, to catch damage from winter storms and prepare for seasonal weather changes. Annual inspections miss developing problems like loose flashing or granule loss that accelerate between visits.

Missing shingles, water stains on ceilings, daylight visible through roof boards, and granules collecting in gutters indicate repair needs. Maintenance addresses wear before failure occurs, while repairs fix existing damage that compromises weather protection.

If your roof is over 20 years old, has widespread shingle curling, or needs repairs covering more than 30% of its surface, replacement becomes more cost-effective. Multiple leak points and failed decking under shingles also tip the decision toward replacement.

Complete estimates cover tear-off and disposal, decking repairs or replacement, underlayment installation, new shingles or roofing material, flashing around penetrations, and ventilation components. Labor, permits, and cleanup should also be itemized separately to show what you're paying for.

Hail impacts crack shingle granules and create bruising that exposes asphalt to UV damage, accelerating aging by 5-10 years depending on severity. Even minor hail reduces weather resistance because damaged spots allow moisture penetration that spreads under surrounding shingles.

Flashing failure causes most penetration leaks — caulk dries out, metal corrodes, or fasteners loosen, creating gaps where water enters. Flashing must seal the transition between roofing material and vertical surfaces, and this seal degrades faster than shingles due to thermal expansion differences.

Material grade, warranty length, decking repair approach, and ventilation upgrades create price differences. Some quotes exclude tear-off disposal, permit fees, or flashing replacement, making low bids appear attractive until add-ons emerge during work.

Clear items from attic spaces since vibration dislodges dust, move vehicles and patio furniture away from the house, and cover pool or AC units to prevent debris damage. Trim tree branches within six feet of the roof to give crews safe access.

Architectural shingles use layered construction creating dimensional texture and typically last 30+ years, while three-tab shingles lie flat with uniform appearance and 20-year lifespans. Architectural shingles resist wind uplift better due to increased weight and bonding surface area.

Attics should stay within 10-15 degrees of outdoor temperature and show no moisture condensation on rafters. Ice dams in winter, excessive cooling costs in summer, and premature shingle aging all indicate ventilation imbalance between intake and exhaust.

Inspectors check shingle condition and fastener security, examine flashing around chimneys and vents, evaluate ventilation airflow, and look for decking sag or water stains from inside the attic. Photos document problem areas so you can see what needs attention and why.

Building codes typically allow one layer over existing shingles if decking is sound and current roof is flat, but this hides decking damage and adds weight that shortens the new roof's lifespan. Tear-off reveals problems and ensures proper installation.
