Professional Roofing Installation & Replacement

Look for widespread missing, cracked, or curled shingles, dark streaks, sagging areas, repeated leaks or interior water stains, granules in gutters, or if the roof is past its expected lifespan — any combination of these signs usually means a professional inspection is needed to determine repair vs replacement.

Most standard residential roof replacements can be completed in one to three days depending on roof size, complexity, weather, and whether the old roof needs a full tear-off or only minor decking repairs; larger or commercial projects will take longer and will be scheduled with a clear timeline.

Experienced roofing crews commonly install asphalt composition shingles, architectural laminated shingles, metal roofing, clay or concrete tile, and flat-roof systems such as TPO, EPDM, or modified bitumen; material selection depends on budget, building type, slope, and local building codes.

A complete estimate should list scope of work (tear-off or overlay), materials and brands, underlayment and ventilation upgrades, flashing replacements, any deck repairs, cleanup procedures, project timeline, permit and disposal costs, and warranty information for materials and workmanship.

Most municipalities require a building permit for a roof replacement; a professional contractor will typically obtain required permits and ensure the work meets local building codes, but you should always confirm permit responsibilities before work begins.

In some areas one overlay (installing new shingles over one existing layer) is allowed, but a full tear-off is often recommended because overlays can hide existing damage, add extra weight, shorten the new roof’s lifespan, and complicate future inspections or repairs.

Roofing professionals can perform a thorough inspection, document damage with photos and a written estimate, provide a scope of repairs, and often help coordinate with your insurance adjuster to ensure covered damage is properly addressed — always confirm the contractor’s experience with insurance claims upfront.

Proper attic ventilation and adequate underlayment are essential for roof performance; during replacement consider ridge vents, soffit vents, attic insulation improvements, and high-quality underlayment to reduce moisture buildup, extend shingle life, and improve energy efficiency.

There are typically two warranty types: manufacturer warranties that cover material defects (length varies by product) and contractor workmanship warranties that cover installation issues; ask for written warranty terms, what they cover, and any required maintenance to keep warranties valid.
