Fast, Reliable Roof Replacement Across St. Augustine
If you need a roof replacement in St. Augustine, expect the job to cost between $11,500 and $28,000 for a typical single-family home, with historic district projects running higher because of architectural review requirements. The review alone adds 2 to 6 weeks before a single shingle comes off. That timeline is real, and it is why you want a roofer who files the HARB paperwork correctly the first time. Call us at (904) 604-7914 and we will walk you through what your specific home needs before you spend a dollar.
Why Birchbark Roofing Jacksonville Is St. Augustine’s Preferred Roof Replacement Company
We know the difference between a 1920s bungalow on Marine Street and a 2015 suburban build off SR-16. St. Augustine is not one housing market, it is several stacked on top of each other, and each one has its own roof failure patterns. Our crews work in Davis Shores, Lincolnville, St. Augustine South, and out toward the beaches, so when we quote your roof we are quoting your actual roof, not a generic Florida roof.
Erik Lindgren runs our St. Augustine work, and he has walked more historic district roofs than most roofers have driven past. We carry materials from GAF, CertainTeed, and Boral locally, which matters when HARB requires a specific tile color and the supplier is two weeks backed up. A live person answers our phone 24/7, including weekends, so when a summer thunderstorm rips a section of decking loose on a Friday night, you reach a human who can start scheduling, not a voicemail tree.
Every quote we write is a written price in dollars before any work starts. No allowances that float. No change orders you did not approve. The 365-Day Done Right Promise covers the full replacement, stamped on every job. That means if something is not right, we make it right. In St. Augustine, where the salt air punishes shortcuts, that promise is not marketing. It is a survival requirement.
Styles & brands we work with






Roof Installation in St. Augustine
Roof installation in St. Augustine generally means a full tear-off and replacement rather than a layover, because most homes here sit in a high-velocity hurricane zone that does not permit a second layer of shingles over compromised decking. A standard asphalt shingle installation on a 1,800-square-foot home runs $11,500 to $16,500, while architectural shingles or metal panels push into the $18,000 to $24,000 range, and historic district tile work can exceed $28,000. We tear off to the decking, inspect the joists and sheathing, replace what is rotted, and install everything to current Miami-Dade and HVHZ standards.
New Construction Rough-In
For new construction in developments west of I-95 or on Anastasia Island, the roof must be installed the same week the walls are dried in, or afternoon thunderstorms soak the framing and you lose two weeks to drying and mold treatment. We coordinate with your GC on material delivery and nail schedules so the job does not stall the build. A new construction roof with architectural shingles typically runs $9 to $14 per square foot of roof area in St. Augustine.
Flat and Low-Slope Roofing
Many pre-1950 homes in the historic district and along King Street have low-slope or flat roofs with original wood decking. Those decks hide rot where scuppers meet parapet walls, and the only way to find it is after tear-off. We budget for decking replacement in our written price up front, so you are not hit with a surprise when the first sheet of plywood comes off and it turns to crumbs.
Roof Replacement Contractor in St. Augustine
A roof replacement contractor in St. Augustine has to do two jobs: the roofing work itself and the paperwork that lets the roofing work happen. In the historic district, that paperwork goes through HARB, the Historic Architectural Review Board, and if it is filed wrong the project stalls. We handle the submittal packet, material samples, color photos, and any resubmissions, and we build the approval wait into the schedule so your roof does not come off until the committee says yes.
Asphalt and Architectural Shingles
Asphalt shingles remain the most common choice outside the historic district, where newer construction dominates neighborhoods like St. Augustine South and along SR-207. We install Tamko and CertainTeed architectural shingles rated for 130-mph sustained winds, with six nails per shingle and full ice and water shield at eaves, valleys, and penetrations. On a typical ranch home, that is a two to three day job once materials are on site.
Roof Decking Replacement
Salt air and humidity eat plywood decking faster than the shingles above it. On Anastasia Island specifically, we regularly find decking that looks fine from the attic but crumbles at the nail line because moisture has sat against the fastener for a decade. We include a per-sheet decking replacement price in the written quote, so when we find bad sheathing after tear-off, the number is already in your hands and approved.
Trusted Brands We Service in St. Augustine
We work with GAF, CertainTeed, and Boral, and we stock the specific products St. Augustine homes need today. That means self-adhered ice and water shield rated for low-slope historic roofs, Boral barrel tile in the terracotta shades HARB approves, and Tamko architectural shingles rated for the wind loads we see off the Atlantic. When your material is needed, we pull from our local inventory before ordering from distributors, which saves days on tight schedules. You will see the exact brand and product line on your written quote, so there is never a substitution game.

AfterCommon Roof Replacement Problems We See in St. Augustine Homes
- Galvanized fastener corrosion on barrier islands. Within a decade of a new roof on Anastasia Island, standard galvanized nails corrode enough that shingles blow off in a 60-mph squall even though the original nailing pattern was correct. We specify stainless steel or copper fasteners on any home within a half mile of the ocean.
- Missing or improper underlayment on low-slope roofs. Contractors who treat a 2:12 historic roof like a standard 5:12 suburban roof skip the self-adhered ice and water shield, and wind-driven rain pushes water up under the shingles at valleys and penetrations. Every low-slope roof we install gets full ice and water shield coverage, not just eaves and valleys.
- Non-HARB materials on historic structures. A homeowner replaces a pre-1900 roof with standard asphalt shingles without approval, the city cites them, and they pay a fine plus the cost of re-roofing with approved material. The review exists because the original roof silhouette is part of the historic fabric. We file before we touch anything.
- Hidden rot at parapet and scupper intersections. Flat-roofed historic buildings drain through scuppers cut into parapet walls, and those intersections are where decades of water intrusion rot the wall framing and decking together. We probe those areas during the estimate, not after the roof is open.

FAQs About Roof Replacement in St. Augustine
Yes. HARB approval is required for roof replacement in the historic district regardless of whether the new material matches the old one, because the city reviews material type, color, profile, and overall appearance against the district’s design guidelines. We file the submittal packet for you and schedule your start date around the approval window. Call (904) 604-7914 and we can tell you whether your address falls inside the district and what the current review timeline looks like.
Stainless steel or copper fasteners. Standard galvanized nails corrode in under a decade from salt spray, and when the fastener fails the shingle blows off even if the nailing pattern and count were correct. This is a small material upgrade at the time of install and a full re-roof if you skip it. We quote stainless or copper fasteners on every barrier island job and it is written on your quote.
We file the HARB application before we order long-lead materials, and we never schedule tear-off until the approval letter is in hand. If the review takes longer than expected, your old roof stays in place and functional. Last spring our crew replaced a low-slope roof on Marine Street in the historic district. The original 1920s wood decking had hidden rot where the scuppers met the parapet walls. We installed ice and water shield over the entire deck, new pressure-treated decking where needed, and copper flashing at the parapet penetrations. Because HARB approved the Boral barrel tile in a terracotta shade weeks before, we tore off and reinstalled in five days with no open roof waiting on a committee. That is how it should work, and how we make it work.
Generally no, for two separate reasons. Most architectural shingles are rated for slopes of 3:12 and steeper, while many historic district roofs are 2:12 or lower, so the manufacturer warranty would be void. Separately, HARB does not approve architectural shingles on many historic structures because the dimensional profile was not part of the original roof design. On a low-slope historic roof, the usual approved options are metal panels or barrel tile. Call (904) 604-7914 and we will tell you what your specific address is likely to get approved for before you fall in love with a material.
St. Augustine sits in a high-velocity hurricane zone, and code requires a sealed roof deck, which means self-adhered underlayment at the minimum across the entire deck, not just felt paper at eaves and valleys. We install full ice and water shield coverage on every replacement because wind-driven rain here moves horizontally and finds any gap between felt courses. On low-slope historic roofs, the entire deck gets a self-adhered membrane before the finish material goes on, which is what keeps water out when the afternoon storm pushes rain sideways for twenty minutes straight.
If your roof is nearing the end of its life in St. Augustine, the first step is a free on-site estimate with exact measurements and a written price. Call (904) 604-7914 and we will walk your roof with you, point to what we see, and hand you a number in writing before we leave. No pressure. Just a roofer with a clipboard and a plan.
