FAQs

If your roof is over 20 years old, has widespread shingle damage, or needs repairs exceeding 30% of replacement cost, replacement makes more financial sense. Multiple leaks or curling shingles across large sections indicate the entire system is failing, not just isolated spots.

Architectural shingles are thicker, last 30-50 years, and offer dimensional texture that mimics wood or slate. 3-tab shingles are thinner, last 15-20 years, and lie flat with a uniform appearance. The durability difference affects long-term cost despite higher upfront pricing for architectural styles.

New siding with proper insulation backing reduces thermal bridging and air infiltration that older siding allows. You'll notice heating and cooling systems cycle less frequently, and interior temperatures stay consistent without thermostat adjustments. The improvement is most noticeable in rooms that previously felt drafty.

Inadequate attic ventilation traps heat that bakes shingles from underneath, causing premature aging and warping. Moisture buildup from poor ventilation also affects shingle adhesion. Installing proper ridge and soffit vents during replacement prevents this heat and moisture damage.

Installing over existing siding is possible but rarely recommended because it hides underlying rot, doesn't allow inspection of sheathing, and creates uneven surfaces that affect new siding performance. Removal reveals structural issues and ensures proper moisture barrier installation.

Inspectors check decking for rot or damage, measure roof pitch and square footage, assess ventilation adequacy, and identify penetration points that need flashing. This reveals whether decking replacement is needed and determines material quantities, which directly affects project cost.

Impact damage to 40% or more of the roof surface, compromised underlayment visible from attic inspection, or multiple shingles missing across different sections typically indicate replacement is necessary. Insurance adjusters use similar thresholds when evaluating storm damage claims.

Complete projects include removing old siding, inspecting and repairing sheathing, installing weather-resistant barrier, adding insulation if specified, installing new siding, and wrapping trim and fascia. Each layer affects moisture protection and energy performance.

Material quality differences, inclusion or exclusion of decking replacement, ventilation upgrades, underlayment type, and warranty coverage all affect pricing. Lower bids often skip ventilation improvements or use thinner underlayment that reduces system lifespan.

Fiber cement and vinyl siding resist moisture damage better than wood in humid environments. Fiber cement won't rot or warp from humidity exposure, while vinyl doesn't absorb moisture at all. Wood siding requires regular sealing and repainting to prevent rot in high-humidity areas.
