What a roof repair really costs to scope
Most repair calls start with a stain on a ceiling or a few pieces of tile in the yard. The price of fixing it depends less on what you can see than on what sits under it: how far the water traveled, the state of the underlayment and deck, the age of the roof and whether the repair is big enough to trigger a county code rule. This guide explains those drivers in plain terms and how Molsbee Roofing turns them into a written scope before any work starts.
Molsbee Roofing has repaired roofs across Palm Beach County since 1975, from our shop in Lake Worth Beach.
What drives the price of a repair?
The roof type and how it is attached. A shingle repair means removing the damaged strips, checking the deck and nailing new ones with at least four corrosion-resistant nails each, woven into the courses around them. A tile repair means lifting tile without cracking its neighbors, then resetting it with the same attachment the roof uses, whether foam adhesive, mortar or mechanical fasteners. Metal repairs depend on whether the problem is a panel, a seam, a fastener or the trim. Flat roof repairs depend on the membrane and whether the insulation under it is wet.
What is under the surface. A leak at a pipe boot may be a small fix. The same leak left through a rainy season may have soaked the underlayment and softened the deck around it. The surface damage is the symptom; the price follows what is underneath.
Where the leak actually starts. Water runs along the underlayment before it shows inside, so the ceiling stain is often not under the failure. Wind-driven rain finds the roof-to-wall joints, the edge metal and the penetrations first. Finding the true source is part of the repair, and it is where a quick patch often goes wrong.
How the new work ties into the old. A repair is only as good as its laps. New underlayment has to run under the sound material uphill and over it downhill, and new flashing has to seal to the existing layers. On an older roof, brittle surrounding underlayment can widen the repair area once it is opened.
Salt exposure. On the barrier islands and along the lagoon, from Ocean Ridge and Manalapan to Singer Island, edge metal, flashing and fasteners are specified for salt, and fastener metals are kept compatible so one does not corrode the other.
Access, height and matching material. Steep pitches, second stories and tight side yards add staging time. Discontinued tile profiles and older shingle colors take longer to source, and we tell you when a close match is the realistic option.
Does a roof repair need a permit here?
Many do, and the permit desk depends on the address. West Palm Beach files through Civic Access, Boynton Beach through SagesGov, Delray Beach through its eServices portal, and Lantana still takes paper applications in person at its Building Division. Unincorporated areas such as Jupiter Farms and The Acreage file with Palm Beach County on ePZB. Where a permit applies, the permit, the inspections and the time the roofer spends meeting the inspector are part of the scope, not an afterthought. We confirm the requirement for your town before we price.
What is the quarter-roof rule?
This is the rule, set by Florida Statute 553.844(5), that turns some repair quotes into replacement conversations. 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.
The age of the house does not tell you which way the rule falls, because many roofs have been replaced since the house was built. Before we quote a repair of any real size, the inspection measures the affected area against that system or section and checks the permit history and the existing roof, and we tell you what applies. If a repair crosses the line, we say so plainly and show you both options in writing.
When is repair the right call?
- The damage is isolated to one area and the rest of the roof is sound.
- The underlayment around the damage is still pliable.
- The repair stays well under the quarter-roof threshold.
- The roof has useful life left for its material.
When does replacement make more sense?
- Leaks are showing up in several places.
- The underlayment is brittle across the roof, not just at one spot.
- The deck is soft in more than one area.
- The repair would cross the line in the quarter-roof rule explained above.
Our guide on when to replace your roof goes deeper on that decision.
What can an inspection see, and what can't it?
A free roof inspection shows damaged tile, shingles or panels, failed flashing and pipe boots, lifted edge metal, and from the attic, staining, daylight and wet insulation. It cannot confirm the underlayment and deck under an intact surface. Where it is safe, we lift a tile or open a small area to look. Anything we still cannot see is written into the scope as a stated unit rate for hidden deck or underlayment work, so a concealed problem is priced before the job, not argued over after it.
How is the repair price built?
- Free roof inspection. We trace the leak from inside and out and check the whole roof, not just the spot you called about.
- Photos of the findings. You see the damage and its likely source, and the photos are yours to keep.
- A written scope with the price before any work starts. What comes off, what goes back, the materials, the attachment method, the permit if one applies and the unit rates for anything hidden.
The written scope is where the number comes from, so two repair quotes can be compared line by line instead of by total alone.
Who stands behind the repair?
A repair should carry the same backing as a new roof. Ours carries our lifetime workmanship warranty, and the materials we install carry the manufacturers' product warranties. Molsbee has held Florida certified roofing contractor license CCC1327429 and has repaired roofs in this county since 1975. We are a GAF Certified Contractor and an Owens Corning Preferred Contractor, and when your insurer asks for it after the repair, we provide a roof certification letter for your insurer. See our repairs and maintenance page for the repairs we handle.
