Not always. On the CWE's historic mansions, slate and tile roofs can often be restored — re-securing and replacing failed pieces and renewing flashing — rather than fully replaced, which is a major cost difference. A full replacement is the call when the material is broadly failing or beyond economical restoration. Your matched verified contractor assesses on-site whether restoration or replacement is the honest answer for your specific roof, rather than defaulting to the bigger job. Material choice on a Central West End replacement is set after an on-roof look, not over the phone, so the recommendation fits your actual roof sections and the neighborhood's housing character.

It depends on the building. A historic single-family on a private place may be a slate or tile restoration-versus-replacement decision with copper and ornamental-metal details, while a brick apartment building is usually a flat or low-slope membrane re-roof. These are different trades. Your matched contractor scopes the specific roof and quotes the appropriate system, weighing upfront cost against the decades of life a premium historic material can deliver. The matched contractor assesses the whole roof on a Central West End home, not just the obvious spot, so the replacement reflects the real condition and you are told honestly what the roof does and does not need.

Landmark and historic-district properties in the Central West End may carry appearance standards for street-visible roofing, so slate, tile, and metal are typically restored or replaced in-kind to preserve the home's character. Your matched pro plans the scope around that and pulls the required City of St. Louis permit. Concealed flat-roof sections on apartment buildings are generally replaced without those constraints. Hidden work — flat-roof membrane, flashing, and gutter replacements behind a parapet — is generally not street-visible and proceeds normally, while the matched Central West End pro pulls any required City of St. Louis permit and plans visible work to preserve the home's character.

The City of St. Louis handles permitting since Missouri has no statewide contractor license — your matched pro pulls it. Warranty depends on the system: premium slate and tile carry long material lives, asphalt and membrane carry manufacturer warranties (longer with a certified installer), and the contractor adds a workmanship warranty. Ask for the material and workmanship terms in writing on the quote, especially on a high-value historic roof. Get the material warranty and the contractor's workmanship warranty for your Central West End replacement in writing on the quote, since the workmanship coverage is what protects the install itself on a multi-decade investment.

When slate or tile is broadly failing beyond economical restoration, when a membrane has reached the end of its service life, or when repeated repairs no longer hold — that is when replacement becomes the sound investment. Your matched verified pro assesses the specific roof on-site and tells you honestly whether restoration or repair still makes sense first. You are never obligated to proceed after the assessment. Rather than sealing the visible stain, a verified Central West End pro traces the water to its actual entry point and addresses that, which on this housing stock is what keeps a replacement from coming back a season later.
