Signs Your Palm Beach County Roof Needs Repairs or Replacement

The warning signs a roof gives before it fails

Roofs rarely fail all at once. They crack, slip, stain and rust first. The useful skill is reading what each sign means underneath: which ones point to a single detail that can be repaired, and which ones point to a worn-out underlayment or deck that no patch will fix.

Molsbee Roofing has inspected roofs in Palm Beach County since 1975. Here are the signs we look for, from the lawn, the attic and the living room, and what each one tells us.

What does cracked or slipped tile actually mean?

On a tile roof, the tile is the shield and the underlayment is the roof. A few cracked tiles over sound underlayment is a repair. Tile that has slipped across a whole slope usually means the attachment has let go: foam adhesive that has lost its bond, mortar that has cracked with age, or fasteners that have corroded. Broken or loose ridge and hip tile is common after wind, because those pieces take the most uplift. In Wellington, where many homes west of State Road 7 carry concrete tile over wood trusses, we count cracked pieces and check truss uplift, not just the surface.

What do shingle signs tell you?

• Curling, cupping or bare patches. Granule loss exposes the asphalt to the sun, and the shingle is near the end of its life.
• A crease across a shingle. Wind lifted it and broke the seal strip. It may lie flat now, but it will keep lifting.
• Exposed or backed-out nails. Code calls for at least four corrosion-resistant nails per shingle; a popped nail can wear through the shingle above it.
• Dark streaks. Mostly cosmetic algae. Growth that holds water is not cosmetic, because it keeps the surface wet.

What are the warning signs on metal and flat roofs?

On metal, look for rust at cut edges and fastener heads, and on exposed-fastener panels, cracked or hardened rubber washers under the screws. Standing seam hides its clips, so its signs show at the seams, trim and penetrations instead. On a flat roof over a porch, garage or addition, look for water that sits more than a day or two after rain, blisters, cracking in the surface, and seams or flashing pulling away at walls and drains.

What about the edges and flashing?

Salt air reaches edge metal and fasteners first. In east Delray Beach, near the Boca Raton oceanfront or at the Jupiter inlet, corrosion at the drip edge and wall flashing is often the first failure. Flashing that has pulled away where the roof meets a wall lets wind-driven rain in behind it, and that water often shows up at an upper window head rather than on a ceiling. Soft or stained fascia boards are another sign that water has been getting behind the edge.

What shows up in the attic and inside the house?

• Daylight through the deck, other than at expected vents.
• Dark staining on the underside of the decking or on rafters and trusses.
• Soft, delaminating or sagging decking.
• A musty smell that points to moisture you cannot see yet.
• Brown rings on ceilings that grow after rain, and bubbling paint at the tops of walls.

Water travels along decking and rafters before it drips, so a stain is often some distance from the opening. Finding the source is part of the inspection.

Is a sagging roof line a repair?

No sign moves faster from covering to structure. A dip at the ridge or between rafters points to deck or framing damage, often from a long-running leak. It needs a professional look soon, and the answer usually involves opening the roof.

Does the age of the house matter?

Yes, because many roofs in the county are original or on their second covering. The typical house in Boca Raton's 33486 dates to 1977; Boca Del Mar and Boca Pointe average 1985; the median Jupiter home dates to 1989, and in Admirals Cove and Jonathan's Landing that often means original tile and underlayment wearing out together. Lake Worth Beach has cottages from 1912 to 1949, where pre-war framing and board decking are inspected before a covering is priced. Attic heat ages underlayment faster than the tile above it, so a tile roof can look sound from the street while the layer that keeps water out has gone brittle.

When does a sign mean repair, and when replacement?

Usually a repair:

• The damage is on one slope or one detail, such as a pipe boot or a flashing joint.
• The rest of the covering and the underlayment are sound.
• The roof has not needed repeated repairs.

Usually a replacement conversation:

• Wear is spread across the roof, not in one spot.
• Leaks keep coming back after repairs.
• The underlayment is brittle across the roof, or the decking is soft.
• The repair would bring the quarter-roof rule into play. Florida's quarter-roof rule: when more than a quarter of a roof system or section is repaired, replaced or recovered in any 12-month period, the roof covering across that entire system or section must be replaced or recovered to meet current code requirements. An exception applies if that system or section was built, repaired or replaced in compliance with the 2007 Florida Building Code or a later edition: only the portion being repaired, replaced or recovered must meet applicable current code requirements. Our inspection helps determine which applies to your roof.

When replacement is the answer, the old covering comes off, the deck is re-nailed to the current fastening schedule, and a secondary water barrier goes on before the new roof. For the full decision, read when to replace your roof in Palm Beach County.

What can an inspection confirm, and what needs the roof opened?

A free roof inspection covers the covering, flashing, penetrations, edge metal and the attic. It cannot confirm the underlayment and decking under intact tile or shingle. When a sign points there, we lift a tile or open a small area where it is safe, and we tell you what we saw, what we suspect and what it would take to confirm the rest.

Every finding is photographed, so you can see the cracked tile, the popped nail or the soft decking yourself. Then you get a written scope with the price before any work starts. If the photos show a repair, the scope is a repair.

Why the answer comes with paperwork

Reading the signs honestly matters more than selling a roof. Molsbee has done that here since 1975 under Florida certified roofing contractor license CCC1327429, as a GAF Certified Contractor and an Owens Corning Preferred Contractor. A repair or a new roof from us carries our lifetime workmanship warranty, new materials carry the manufacturers' product warranties, and after the work we provide a roof certification letter for your insurer when you ask for one.
