Frequently Asked Questions

The 10-year workmanship warranty covers labor-related installation defects on full roof replacements, including issues with underlayment installation, shingle application, flashing integration, and sealing. Material defects are covered separately by manufacturer warranties. This warranty applies when licensed contractors complete the entire replacement using quality materials and proper techniques.

Re-roofing works when the existing roof structure remains sound with only one layer of shingles present and no underlying water damage or rot. If decking shows soft spots, multiple shingle layers exist, or leaks have compromised underlayment, full replacement becomes necessary. Inspection reveals whether the roof foundation can support overlay installation.

Metal roofing sheds snow efficiently due to its smooth surface, reducing ice dam formation common in Sierra Nevada foothill winters. The material resists wind damage from seasonal storms, reflects summer heat to improve energy efficiency, and outlasts asphalt shingles by decades. Metal roofs handle temperature swings between mountain winters and hot valley summers without cracking.

Flashing seals roof penetrations where chimneys, vents, and valleys create vulnerable leak points. When flashing deteriorates or pulls away, water infiltrates underlayment and decking, causing rot that spreads beyond the visible leak location. Catching flashing damage early prevents structural repairs that cost significantly more than the flashing replacement itself.

Annual inspections catch storm damage, shingle deterioration, and early leak signs before they require expensive structural repairs. Homes under oak trees need more frequent checks since falling branches and leaf debris accelerate wear. Schedule inspections after severe weather and before listing properties for sale to address issues proactively.

Certification inspections assess remaining roof life, current condition of materials, signs of leak damage, flashing integrity, and structural concerns affecting safety or insurability. The documentation includes photos and written findings that lenders and insurers require. Certifications confirm whether the roof meets minimum standards for property transfer or needs repairs first.

Tile roofs require walking on sound tiles without causing breakage, replacing individual cracked tiles that can't be patched, and verifying underlayment condition beneath damaged sections. Tiles last decades but underlayment deteriorates faster, so repairs often address hidden waterproofing while preserving intact tiles. Proper tile roof work prevents cascade damage from walking improperly or using wrong replacement tiles.

Immediate repair is needed for active leaks, missing shingles exposing underlayment, lifted flashing, or visible water stains on interior ceilings. Routine maintenance addresses granule loss, minor curling, gutter cleaning, and moss buildup before they cause leaks. Waiting on urgent repairs allows water damage to spread into decking and insulation.

Properly installed gutters direct roof runoff away from foundations, preventing soil erosion that leads to settling and basement water intrusion. Without functional gutters, water cascades off roof edges, rotting fascia boards and saturating ground near foundations. New gutters with correct slope and downspout placement eliminate pooling that accelerates both roof edge decay and foundation movement.

Skylight leaks stem from deteriorated seals around the glass, failed flashing integration with surrounding shingles, or cracked skylight frames that allow water past the glazing. Permanent repairs require removing shingles around the skylight, installing new waterproof underlayment and step flashing, then properly sealing the skylight frame. Surface caulking only provides temporary relief because it doesn't address flashing failures.

Roof pitch steepness increases labor costs due to safety equipment and slower work pace. Material choice varies widely, with metal and tile costing more than asphalt but lasting longer. Complexity from multiple roof planes, skylights, and chimney flashing adds time. Decking replacement becomes necessary when water damage has compromised the structure beneath old shingles.

Regular maintenance catches minor issues like lifted shingles, small leaks, and worn flashing before they require full section replacement. Cleaning debris from valleys and around chimneys prevents water pooling that accelerates deterioration. Annual inspections identify problems during early stages when repairs cost hundreds instead of thousands, often adding 5-10 years to roof lifespan.
