Roofing Questions
How much does a new roof cost in Pennsylvania?
Most asphalt roof replacements Greenawalt Roofing sold from November 2024 to October 2026 cost between about $8,800 and $17,200, with a median of about $12,900; large or complex roofs can run $24,000 or more. The price depends on the size of your home, roofing material, and complexity of the installation. Greenawalt Roofing provides free, transparent estimates with no hidden fees so you know exactly what to expect before work begins.
How long does a new roof last?
Asphalt shingle roofs typically last 20 to 30 years, while architectural shingles like CertainTeed Landmark Pro can last 30 to 50 years with proper ventilation and maintenance. Metal roofing systems can last 40 to 70 years. The actual lifespan depends on material quality, installation workmanship, and local weather exposure.
How do I know if my roof needs to be replaced?
Common signs include missing or curling shingles, granules accumulating in your gutters, daylight visible through the attic, sagging roof sections, and your roof being over 20 years old. Greenawalt Roofing offers free inspections, our HAAG-certified inspectors can assess your roof’s condition and advise whether repair or replacement is the best option.
Does homeowner’s insurance cover roof replacement?
Insurance typically covers roof damage caused by sudden events like hail, wind, or fallen trees, but not damage from normal wear and aging. Greenawalt Roofing’s HAAG-certified inspectors work directly with your insurance adjuster to document storm damage and help ensure your claim reflects the full scope of necessary repairs.
What roofing materials does Greenawalt install?
We install asphalt shingles (including CertainTeed and GAF premium lines), standing-seam and exposed-fastener metal roofing, rubber (EPDM) systems, TPO membranes, and modified bitumen for flat and low-slope roofs. As a CertainTeed ShingleMaster PREMIER, we offer extended manufacturer warranties on qualifying installations.

Roof Repair Questions
Can a roof be repaired instead of replaced?
Yes, many roof issues can be resolved with targeted repairs rather than a full replacement. Localized damage from storms, isolated leaks around vents or flashing, and small areas of missing shingles are all repairable. If your roof is under 15 years old and the damage is confined to a specific area, repair is typically the most cost-effective option.
How much does a roof repair cost?
Minor roof repairs such as replacing a few shingles or resealing flashing typically cost between $300 and $1,500. More extensive repairs involving larger damaged areas, decking replacement, or multiple leak sources can range from $1,500 to $5,000. Greenawalt Roofing provides free inspections and detailed estimates before any work begins.
Does insurance cover roof repair from storm damage?
Homeowner’s insurance generally covers roof repairs caused by sudden storm events including hail, wind, and fallen tree limbs. Damage from gradual wear, aging, or deferred maintenance is typically not covered. Greenawalt Roofing’s HAAG-certified inspectors document storm damage to insurance industry standards and work directly with your adjuster.
How quickly can you repair a roof leak?
Emergency tarping and temporary repairs can typically be completed within 24 to 48 hours of your call. Permanent repairs are usually scheduled within one to two weeks, depending on weather conditions and material availability. If your roof is actively leaking, call us immediately, delaying repair allows water to damage insulation, drywall, and framing.
How do I find where my roof is leaking?
Roof leaks often appear inside your home far from their actual source, as water travels along rafters and sheathing before dripping through. Common leak sources include deteriorated flashing around chimneys, failed pipe boots, damaged valley channels, and lifted shingles. A professional inspection is the most reliable way to trace a leak to its origin.

Metal Roofing Questions
How long does a metal roof last?
A properly installed metal roof lasts 40 to 70 years depending on the material and coating system. Standing-seam steel with Kynar 500 paint finish offers the best combination of longevity and aesthetics, with manufacturer warranties of 40 years or more on both the panels and the finish.
Is a metal roof worth the extra cost?
Metal roofing costs 2 to 3 times more than asphalt shingles upfront, but lasts 2 to 3 times longer and requires virtually no maintenance. When you factor in avoided replacement costs, lower energy bills (10-25% cooling savings), and increased home resale value, metal roofing often has a lower total cost of ownership over the life of your home.
Are metal roofs noisy when it rains?
No. Modern metal roofing installed over solid decking and underlayment is no louder than asphalt shingles during rain. The solid substrate and attic insulation beneath the panels absorb sound effectively. The perception of noisy metal roofs comes from agricultural buildings where panels are installed directly on open purlins without insulation.
Can you install a metal roof over existing shingles?
In some cases, yes. Metal roofing can be installed over a single layer of existing asphalt shingles if the decking is in good condition and local building codes allow it. This saves on tear-off costs and disposal fees. However, a full tear-off is recommended when there is underlying decking damage or two layers of existing shingles.
Do metal roofs attract lightning?
No. Metal roofing does not increase the likelihood of a lightning strike. Lightning strikes the highest point in an area regardless of material. In fact, metal roofing is safer during a lightning event because it is non-combustible, it disperses the energy across the structure rather than catching fire like wood or asphalt materials can.

Flat & Commercial Roofing Questions
What is the difference between TPO and EPDM roofing?
TPO is a white thermoplastic membrane with heat-welded seams that reflects solar energy and reduces cooling costs. EPDM is a black rubber membrane with adhesive or tape seams that excels in flexibility and cold-weather performance. TPO is generally preferred for energy efficiency and seam strength, while EPDM offers a proven 60-year track record and lower material cost.
How long does a flat roof last?
TPO and EPDM flat roofing systems typically last 20 to 30 years with proper installation and regular maintenance. Modified bitumen systems last 15 to 25 years. Lifespan depends heavily on membrane thickness, installation quality, and whether the roof receives regular inspections and maintenance to catch issues early.
Why does my flat roof have ponding water?
Ponding water, standing water that remains 48 hours after rain, is caused by inadequate drainage due to sagging decking, clogged drains, or insufficient roof slope. Ponding accelerates membrane deterioration and adds structural weight. Solutions include adding tapered insulation to create positive drainage, installing additional drains, or rerouting water flow.
Can a flat roof be repaired or does it need full replacement?
Many flat roof issues can be repaired, including membrane punctures, open seams, flashing separations, and localized ponding. If damage is confined to less than 25% of the roof area and the membrane is within its expected lifespan, targeted repairs are usually more cost-effective than full replacement.
How often should a flat roof be inspected?
Flat roofs should be professionally inspected at least twice per year, once in spring and once in fall, plus after any severe storm event. Regular inspections catch small issues like open seams, blocked drains, and membrane punctures before they cause interior water damage. Most flat roof warranties require documented maintenance to remain valid.

Siding Questions
What type of siding is best for homes in Pennsylvania?
Fiber cement siding (like James Hardie) and vinyl siding are the two most popular choices for Pennsylvania homes. Fiber cement offers superior durability and a wood-like appearance, while vinyl provides excellent value with minimal maintenance. The best choice depends on your budget, desired look, and how long you plan to stay in your home.
How long does vinyl siding last?
Quality vinyl siding typically lasts 20 to 40 years with minimal maintenance. Premium brands like CertainTeed and Mastic offer thicker panels with better fade resistance and impact ratings. Proper installation with correct nailing patterns and overlap is critical to achieving the full lifespan.
How much does siding replacement cost?
Full siding replacement for an average-sized home in the mid-Atlantic region typically ranges from $10,000 to $35,000, depending on material choice, home size, and the amount of trim and detail work required. Greenawalt Roofing provides free estimates that include material options at different price points.
Can new siding improve my home’s energy efficiency?
Yes. Modern insulated siding adds an R-value layer to your home’s exterior, reducing thermal bridging through wall studs. Insulated vinyl siding can improve energy efficiency by up to 20 percent compared to uninsulated options, lowering heating and cooling costs year-round.
Does Greenawalt Roofing install James Hardie siding?
Yes, Greenawalt Roofing installs James Hardie fiber cement siding along with CertainTeed, Mastic, and other premium siding brands. Our crews are trained in manufacturer-specific installation techniques to ensure your warranty remains fully valid.

Gutters Questions
What are seamless gutters and why are they better?
Seamless gutters are custom-fabricated on-site from a single piece of aluminum, eliminating the joints and seams where traditional sectional gutters leak. With no seams to separate or clog, seamless gutters require less maintenance and last significantly longer: typically 20 to 30 years.
How often should gutters be cleaned?
Gutters should be cleaned at least twice a year — once in late spring and once in late fall after leaves have dropped. Homes surrounded by trees may need quarterly cleaning. Installing gutter guards can significantly reduce cleaning frequency by preventing leaves and debris from entering the gutter trough.
What size gutters does my home need?
Most residential homes use 5-inch K-style gutters, which handle rainfall on standard roof sizes. Homes with large roof areas, steep pitches, or heavy rainfall exposure may require 6-inch gutters or additional downspouts. Greenawalt Roofing evaluates your roof’s drainage needs during our free estimate to recommend the right size.
Do gutter guards really work?
Quality gutter guards significantly reduce debris accumulation and cleaning frequency. Micro-mesh and surface-tension guards are the most effective styles, blocking leaves, pine needles, and shingle granules while allowing water to flow freely. They don’t eliminate maintenance entirely but reduce it to an annual inspection in most cases.
How much do new gutters cost?
Seamless aluminum gutter installation for an average home typically costs between $1,500 and $4,000, depending on the home’s size, number of stories, and amount of downspout work needed. Gutter guard systems add approximately $5 to $15 per linear foot. Greenawalt Roofing includes gutter estimates as part of any exterior project assessment.

Warranty Questions
What does a roofing warranty cover?
Roofing warranties typically include two components: a manufacturer’s material warranty covering defects in the shingles or membrane, and a workmanship warranty from the installer covering labor and installation quality. Greenawalt Roofing provides both, our CertainTeed ShingleMaster PREMIER certification qualifies you for extended manufacturer warranties of up to 50 years that include labor coverage.
Is a roof warranty transferable when I sell my home?
CertainTeed’s 50-year SureStart warranty is transferable within the first 10 years, and their 30-year warranty is transferable within the first 5 years. GAF warranty transfer policies vary by product. Transfer typically requires notifying the manufacturer within 60 days of the home sale. A transferable warranty adds measurable value when selling your home.
What voids a roofing warranty?
Common warranty-voiding actions include improper ventilation (the #1 cause of warranty claims denial), unauthorized modifications or repairs by non-certified contractors, failure to maintain the roof per manufacturer guidelines, and installing incompatible products on top of warranted materials. Greenawalt Roofing ensures proper ventilation and installation to protect your warranty.
Does Greenawalt Roofing offer a workmanship warranty?
Yes. Every Greenawalt Roofing installation includes our workmanship warranty covering labor and installation quality. The specific terms depend on the project scope and materials used. As a CertainTeed ShingleMaster PREMIER, our workmanship warranties are backed by both our company and the manufacturer.
