Which review applies to your address
Charleston peninsula: the City of Charleston Board of Architectural Review covers the Old and Historic District and the other designated districts on the peninsula and in some areas beyond it. Exterior changes visible from a public right of way are reviewed, and on contributing structures the review can extend to roof material and color even when the change is modest. Some routine roof applications may be handled at staff level and others go to the board; we confirm which track your address takes.
Mount Pleasant Old Village: the town's historic review covers the blocks around Pitt Street, Bennett Street, and the harbor front, and its attention is heaviest on street-facing slopes and on material or color changes.
Sullivan's Island: the town's review body covers the historic overlay and can reach houses outside it under the island's design rules, so we confirm from your parcel whether your roof goes to review. Material, finish, and color are part of it, and wind-uplift attachment is part of the plan review at the same time.
Walterboro and Summerville: both have designated historic districts in their older cores. Where a local review applies it is typically lighter than the peninsula's and often turns on visible material and color. We confirm with the town whether your address is inside a district.
In every case, the first thing we do with your order is confirm your jurisdiction and whether a review applies. If it does, the review sits on the calendar before the roof is scheduled.
What typically gets reviewed, and what typically does not
Review boards care about what can be seen. The three things that usually matter are the visible material, the color, and the profile: whether the roof is shingle, metal, slate, or tile; what color and sheen it is; and, for metal, the panel width and seam height that give the roof its texture from the street.
What usually stays out of review is what is under the roof. Underlayment, a sealed deck, ice and water barrier, decking, ventilation, flashing, and the nailing pattern are building code matters the permit office checks, so a historic house can carry a modern, hurricane-rated assembly under a historically appropriate surface. That is what we recommend nearly every time.
Rules change and every application is judged on its own, so treat everything on this page as the usual pattern rather than a guarantee. We confirm current requirements with the board's staff for each order.
Like-for-like versus a material change
The simplest historic district roof job is a like-for-like replacement: the same material, in the same or a very close color, in the same profile. An architectural shingle replacing an architectural shingle, or standing seam replacing older standing seam in a similar width and color, is often a short review. Boards generally want to see that the replacement is at least as appropriate as what is there now.
A material change is a different conversation. Shingle to standing seam, or asphalt to a slate look-alike, is reviewed as a change to the character of the house, and the board will want to know why the new material suits the building's age and style. On many peninsula houses metal was the original roof and the shingle is the intrusion, and boards have often received standing seam well on that basis. On a 1920s bungalow that always had shingle, the case is weaker.
Color changes within the same material sit between the two. Muted, historically plausible colors tend to move quickly. Bright, high-contrast, or high-gloss colors tend not to.
Standing seam profiles that tend to be received well
Standing seam and flat-lock metal roofs were the roof of choice on Charleston single houses and piazzas in the nineteenth century, which is why standing seam is one of the easier materials to get approved when the details are right. The details are panel width, seam height, and finish.
Panel width: traditional narrower widths put more seams on the roof and read as historic from the street. Very wide panels read as commercial or contemporary and are the common reason a metal application is sent back.
Seam height: a low-profile seam matches the look of old terne and tin roofs. Tall, boxy seams read as modern.
Finish: low-gloss and non-reflective. Colors that read as historic metal, such as natural mill or silver-grey, charcoal, dark green, and certain deep reds, are the ones boards have typically approved; bright colors and high-gloss finishes typically are not. The Pearl Metal uses hidden-fastener aluminum in a low-gloss PVDF finish, and we bring the color chip and a panel sample to the submission.
Slate look-alikes and other options for old houses
Some peninsula and Old Village houses carry slate or, more rarely, clay tile. Replacing real slate with real slate is possible but expensive and heavy, and many old roof frames were never built to carry a full slate load. Synthetic slate, a polymer or rubber composite in slate colors and textures, is much lighter, is rated for coastal wind, and has been approved on some historic houses when the profile and color match closely. It is a case-by-case decision; ask us, and we'll recommend a pre-application conversation with the board's staff first.
Architectural shingle in a muted, dimensional profile remains the most common historic district roof, because most houses in these districts have carried shingle for decades. A charcoal or weathered-wood shingle on a house that already has shingle is usually a short review. Our three shingle packages all use the same TAMKO Titan XT shingle, so the board sees the same shingle whichever package you choose; the difference is the assembly and the warranty.
Copper and terne-coated stainless suit some high-style peninsula houses and details such as bays and piazza roofs. They are specialty work outside the package ladder; ask us and we'll tell you whether we can price it for your house.
Old decks, plank sheathing, and ventilation
Houses built before the middle of the twentieth century usually have plank decking: individual boards, often with gaps between them, rather than plywood sheets. Much of it is heart pine that will outlast anything nailed to it. The issues are gaps too wide to hold a nail, boards split or rotted around chimneys and valleys, and, on the oldest houses, skip sheathing built for wood shingles that cannot take a modern roof directly.
The quote handles this with a stated per-board or per-sheet price for replacement and, where the gaps are too wide for shingle, a plywood overlay over the existing planks, priced once we've confirmed what is under the existing roof. On a standing seam roof we usually recommend a solid overlay regardless, because the clips need continuous wood to bite into. We photograph the deck at tear-off.
Ventilation is the other retrofit. Many old houses have no soffit or ridge ventilation at all. A ridge vent on a historic roof is normally invisible from the street and rarely a review issue, but it has to be paired with intake at the eaves or it does nothing; where there is no soffit to vent, low-profile intake vents near the eave are usually acceptable for the same reason. A sealed deck matters more than usual on a plank-decked house, because the gaps between boards are where wind-driven rain enters when shingles are lost.
How we prepare the submission with your order
Paperwork is what loses homeowners a season, so the sequence is simple. When you place your order, online or after a booked appointment, we confirm your address against the district maps. If a review applies, we prepare the application: the product data sheet, the color chip or panel sample, the panel width and seam profile for metal, photographs of the existing roof from the street, and, where the board asks, a drawing showing which slopes are visible.
You sign the application as the owner. We file it, track it, and attend the staff or board review where one is required. The install date is held on our calendar from the day you order and moves only if the review runs past the typical window. No payment is taken online while the review is pending, and if the board declines a material, you can change the package or cancel.
Timelines vary by board and by whether the application is handled at staff level. Staff-level like-for-like approvals are typically a couple of weeks; full board reviews of a material change follow the board's meeting schedule and run longer. We confirm the current schedule when we file and tell you the date we're working toward.
What to expect on install day in a historic district
Old houses in old streets need a different install plan. Peninsula lots are narrow and often have no driveway, so the dumpster and delivery are coordinated with the city's right-of-way rules and, on some streets, a permit for the container. Old Village and Sullivan's Island lots are wider but have mature trees and close neighbors. We stage material so the piazza, the garden, and the neighbor's car are protected, and we don't leave a deck open overnight.
Expect a longer tear-off than on a newer house. Plank decks come up slower, layered old roofs are common, and there are usually surprises at chimneys and valleys. The written price covers the known conditions; the per-board decking price covers the rest, with photographs.
