Roofers Boston: Slate, EPDM, Shingle Guide
Boston's roofing companies work across three main materials: slate, EPDM rubber, and asphalt shingles. Each fits different building types and budgets.

Asphalt Shingle Roofs
Asphalt shingles remain the most common and affordable option for pitched roofs on single-family homes and triple-deckers across neighborhoods like Hyde Park and West Roxbury.
They typically last 20-25 years in Boston's climate when properly ventilated and installed with ice-and-water shield along the eaves.
EPDM Rubber for Flat Roofs
Many triple-decker rear additions and rowhouse roofs are flat or low-slope, making EPDM rubber membrane the standard choice over shingles.
EPDM roofs generally last 15-25 years and cost $6,000 to $12,000 to replace, with seams needing periodic inspection for separation.
Slate Roofs on Historic Homes
Brownstones and older Victorian homes in Beacon Hill and Back Bay often still carry original slate roofing, prized for its 75-100 year lifespan but costly to repair or replace.
Because slate crews are specialized, repairs cost more per square foot than shingle work, and full replacements can exceed $25,000.
Choosing the Right Roofer for Your Material
Not every roofing company handles slate repair well, so ask specifically about slate experience if you own a historic home.
For flat roofs, confirm the roofer's EPDM warranty terms, since seam failures are the most common source of leaks on that material.
Typical cost ranges
| Asphalt shingle reroof | $8,500 - $15,000 |
| EPDM flat roof replacement | $6,000 - $12,000 |
| Slate partial repair | $2,500 - $6,000 |
| Full slate replacement | $25,000 - $55,000 |
Ranges are general estimates gathered from homeowner-reported quotes, not an offer or a quote for your project.
Common questions
Which roofing material lasts longest in Boston?
Slate can last 75-100 years, far longer than asphalt shingles at 20-25 years or EPDM rubber at 15-25 years, but it costs significantly more upfront.
Is EPDM rubber roofing good for Boston winters?
Yes, EPDM handles freeze-thaw cycles well when properly installed and seamed, making it a common choice for flat sections on triple-deckers.
Do I need a specialist for slate roof repair?
Yes, slate work requires roofers experienced in handling and matching slate tiles, since general shingle crews often lack the right tools and technique.
Can I mix roofing materials on one building?
Yes, many Boston triple-deckers have asphalt shingles on the pitched main roof and EPDM rubber on flat rear sections, which is a common and accepted combination.
