Residential Roofing 101

The average asphalt shingle roof lasts 20–30 years. Metal, tile, and slate roofs can last 40–100 years with proper maintenance. Roof lifespan depends on materials, climate, ventilation, and maintenance frequency.

Signs include missing or curling shingles, roof leaks, water stains on ceilings, granules in gutters, sagging rooflines, or a roof that’s over 20 years old. A professional inspection can confirm replacement needs.

Asphalt shingles are the most common and affordable for residential homes. Metal roofs offer durability and energy efficiency. Tile and slate are high-end options with long lifespans. Your home’s style, budget, and climate affect the best choice.

Roof repair fixes localized issues like a leak, missing shingles, or flashing damage. Roof replacement involves removing the existing roof and installing a new one across the entire surface. Replacement is needed when damage is widespread or the roof is too old.

Yes. New roofing systems often include reflective shingles or proper attic ventilation, which reduces heat absorption and improves energy efficiency. This can lead to lower cooling and heating costs.

Roof costs are based on square footage, pitch, number of layers, accessibility, materials used, and local labor rates. Additional factors include underlayment type, flashing upgrades, and whether existing decking needs repairs.

Most policies cover damage from sudden events like storms, hail, or fallen trees. Insurance does not usually cover roof wear and tear or damage due to poor maintenance. Always review your policy and get a roof inspection before filing a claim.

Most standard residential roofs can be replaced in 1–2 days. Larger or more complex roofs may take longer. Weather and material availability can also affect timing.

No, you don’t have to be home. Most reputable roofing companies can complete the job while you’re away. However, being available for questions or access to the attic (if needed) can be helpful.

Roof ventilation allows air to circulate through your attic, preventing moisture buildup and reducing heat. Proper ventilation helps extend roof life, lower energy bills, and prevent mold or rot.

It’s often a good time to replace or upgrade gutters during a roof replacement. Gutters and roofing work together to manage water drainage and protect your home’s foundation, siding, and fascia boards.

Underlayment is a waterproof barrier installed between the roof deck and shingles. It provides an extra layer of protection against water, wind, and ice. Modern synthetic underlayments offer better performance than traditional felt.

Spring, summer, and early fall are ideal times for roof work due to stable weather. However, professional roofing crews can install roofs year-round with proper planning and safety measures.

Clear your driveway and yard of vehicles and fragile items. Take down wall decorations indoors. Keep pets and kids indoors during the process. The roofing company should provide a prep checklist ahead of time.

Warranties typically cover materials (from the manufacturer) and workmanship (from the contractor). Length and terms vary—some warranties extend 25–50 years or offer lifetime coverage. Ask about what’s included in writing.

Yes. If the roof is generally in good shape and damage is localized, a repair is often a cost-effective solution. If damage is widespread or the roof is aging, replacement may be the better long-term investment.

A roofing inspection evaluates the condition of your roof, flashing, ventilation, and gutters. It helps identify leaks, storm damage, or early signs of failure. Annual inspections are recommended to extend roof life and prevent costly repairs.

Delaying roof replacement can lead to interior water damage, mold growth, insulation damage, and structural rot. Minor issues can become major, more expensive repairs. Timely replacement protects your home and prevents escalating damage.

Look for licensed, insured, and certified contractors with strong local references. Check reviews, ask for written estimates, and confirm warranties. Choose a roofer who communicates clearly and doesn’t pressure you into decisions.

Schedule annual inspections, clean gutters regularly, remove debris and moss, trim overhanging branches, and watch for leaks or flashing issues. Preventative care helps catch small problems before they become major repairs.
