7 Signs You Need a New Roof (Philadelphia Homeowner's Checklist)

Knowing the signs you need a new roof can save you thousands of dollars and a lot of headaches. As Philadelphia homeowners, our roofs take a beating -- from summer thunderstorms that roll up the Delaware Valley to nor'easters that dump ice and snow for days, to the relentless freeze-thaw cycles that crack and lift shingles all winter long.

At Adilay Roofing, we've inspected thousands of roofs across Philadelphia, Bucks County, Montgomery County, Delaware County, and Chester County over our 20+ years in business. We've seen roofs that looked fine from the street but were one storm away from catastrophic failure, and we've seen homeowners catch problems early and save thousands.

Here are the seven roof damage signs every Philadelphia homeowner should know -- and what to do about each one.

1. Your Roof Is Over 20 Years Old

Age is the single most reliable predictor of when to replace a roof. Every roofing material has a lifespan, and Philadelphia's harsh weather shortens it:

• 3-Tab asphalt shingles: 15-20 years
• Architectural shingles: 25-30 years
• EPDM rubber (flat roofs): 20-30 years
• Metal roofing: 40-70 years
• Slate: 75-100+ years

If your home was built or re-roofed in the early 2000s with standard asphalt shingles, you're already in the replacement window. Many row homes in South Philly, Fishtown, and Kensington are hitting this age right now.

Pro tip: If you bought your home recently and don't know the roof's age, check your home inspection report or look in the attic for installation date stamps on the underlayment.

2. Shingles Are Curling, Cracking, or Missing

Walk to the sidewalk and look up at your roof. What you're looking for:

• Curling edges: Shingles that are lifting at the corners or tabs curling upward. This exposes the underlayment to UV rays and water.
• Cracking: Visible cracks running through shingles, often caused by years of thermal expansion and contraction through Philadelphia's hot summers and cold winters.
• Missing shingles: Gaps where shingles have blown off entirely, leaving the underlayment or decking exposed.

A few missing shingles after a big storm might be a repair job. But widespread curling or cracking across large sections of the roof is one of the clearest signs you need a new roof rather than a patch.

If you spot shingle damage, schedule a roof inspection in Philadelphia sooner rather than later. What seems like cosmetic damage on the surface often masks deeper problems underneath.

3. Granules Are Filling Your Gutters

Check your gutters and downspouts after the next rain. If you're finding piles of coarse, sand-like granules, your shingles are breaking down.

Asphalt shingles are coated with ceramic granules that protect them from UV rays. When those granules start shedding in large quantities, the shingles are approaching the end of their life. The underlying asphalt dries out, cracks, and loses its waterproofing ability.

Some granule loss is normal on a brand-new roof (manufacturing excess). But on a roof that's 10+ years old, heavy granule loss is a warning sign. You may also notice dark, bare patches on the shingles where granules have worn away entirely.

This is especially common on south-facing slopes in Philadelphia, which take the full force of summer sun. Homes in neighborhoods with minimal tree cover, like parts of Northeast Philly and much of South Philadelphia, tend to lose granules faster.

4. You Can See Daylight Through the Roof Boards

Head up to your attic on a sunny day and turn off all the lights. If you can see pinpoints of daylight coming through the roof boards, you have a problem. Those gaps mean water is getting in too.

While you're up there, look for:

• Water stains on rafters or decking: Dark streaks or discoloration indicate past or ongoing leaks.
• Sagging decking: Plywood that dips between rafters has been compromised by moisture.
• Mold or mildew: A musty smell or visible mold growth means moisture has been present for a while.

Philadelphia's older homes, especially row homes built before 1960, sometimes have skip sheathing (spaced boards) instead of solid plywood decking. This makes attic inspections particularly important because leaks can travel along boards before dripping down, making the source hard to pinpoint.

If you see any of these roof damage signs in your attic, don't wait. Contact a professional for roof replacement services or professional roof repair depending on the extent of the damage.

5. Your Roof Is Sagging

A sagging roofline is a serious structural issue that demands immediate attention. Stand across the street from your home and look at the ridge line (the peak of your roof). It should be straight and level. Any dipping, bowing, or waviness indicates:

• Compromised decking: Plywood weakened by prolonged moisture exposure.
• Structural issues: Damaged rafters, trusses, or load-bearing components.
• Excessive weight: In rare cases, multiple layers of shingles can overload the structure.

In Philadelphia row homes, sagging can also occur along party walls where water infiltration at the parapet has rotted the structural members over years. This is one of the most common issues we see when performing a roof inspection in Philadelphia on attached homes.

A sagging roof is not a DIY situation and it's not something to "keep an eye on." If you notice sagging, call us at (888) 823-4766 immediately. We offer 24/7 emergency roof service for situations exactly like this.

6. Your Energy Bills Are Climbing

A sudden or unexplained increase in your heating or cooling bills can point to a failing roof. When shingles deteriorate, underlayment breaks down, or ventilation is compromised, your attic can become an oven in summer and an icebox in winter, forcing your HVAC system to work overtime.

In Philadelphia's climate, where summer temperatures hit the 90s and winter lows drop into the teens, a properly functioning roof and attic ventilation system is critical for energy efficiency. Signs of roof-related energy loss include:

• Ice dams in winter: Ridges of ice along the eaves caused by heat escaping through the roof, melting snow that refreezes at the colder eaves. This is a common problem on Philadelphia row homes with poor attic insulation.
• Extremely hot attic in summer: If your attic is 20-30 degrees hotter than the outside temperature, ventilation may be failing.
• Uneven temperatures: Rooms on the top floor that are noticeably hotter or colder than the rest of the house.

7. Flashing Is Damaged or Missing

Flashing is the metal (usually aluminum or galvanized steel) installed around chimneys, vents, skylights, and where the roof meets a wall. Its job is to direct water away from these vulnerable joints.

Damaged, rusted, or missing flashing is one of the top causes of roof leaks in Philadelphia. Check for:

• Rust or corrosion on visible flashing
• Gaps or separation where flashing meets the wall or chimney
• Caulk failure: Dried, cracked, or missing sealant around flashing edges
• Stains on interior walls near chimneys or where the roof meets exterior walls

On Philadelphia row homes, parapet wall flashing (sometimes called "counter flashing" or "cap flashing") is absolutely critical. The shared walls between row homes are prime leak locations, and failed flashing at these joints causes more service calls in our experience than any other single issue.

What to Do If You Spot These Signs

If you've identified one or more of these signs you need a new roof, here's your action plan:

Step 1: Don't Panic, But Don't Wait

One warning sign might mean a repair. Multiple warning signs, especially on a roof that's 15+ years old, usually mean it's time for a Philadelphia roof replacement. The worst thing you can do is ignore the problem through another winter. One nor'easter can turn a manageable replacement into a major renovation.

Step 2: Schedule a Professional Inspection

A ground-level visual check is a good start, but a full roof inspection in Philadelphia requires getting on the roof, checking the attic, and evaluating components you can't see from the street.

At Adilay Roofing, our inspections are thorough and free. We'll check every component, document what we find with photos, and give you an honest assessment of whether you need a repair or a full replacement. No pressure, no scare tactics. Just the truth about your roof's condition.

Step 3: Get a Detailed Estimate

If replacement is recommended, get a written estimate that breaks down every cost, including materials, labor, tear-off, disposal, permits, and any structural repairs. Our guide on roof replacement costs in Philadelphia will help you understand what to expect.

Step 4: Choose the Right Contractor

Not all roofing contractors are created equal. Before signing a contract, make sure your contractor is licensed, insured, and experienced with Philadelphia's unique roofing challenges. Check out our guide on how to choose a roofing contractor in Philadelphia for a complete checklist.
