A historic roof is an architectural record as well as a weather barrier. Restoration begins with evidence: existing materials, older photographs, previous repairs, and the details that define the roof silhouette.
Record before intervention
Document slate sizes, blends, patterns, exposure, hips, ridges, valleys, and distinctive metalwork. The National Park Service recommends identifying character-defining details before work begins. Previous alterations should be understood rather than automatically repeated.
Confirm the review path
Ask the relevant town offices whether the property or proposed scope is subject to historic, building, or other review. Requirements vary by designation and project. Do not assume every older house is protected, or that a roof replacement is exempt from approval.
Compare restoration proposals carefully
Look for a condition record, retention and salvage plan, material-matching approach, temporary protection, and a clear list of changes. Ask whether conservation design or structural advice is needed. Keep samples and photographs in a property archive so future work can respect the same evidence.
A FEW CONSIDERATIONS
Before we begin.
Does every old house require historic approval?
No. Designation, district boundaries, and the scope of work matter. Confirm the specific property and proposed changes with the appropriate town offices before ordering materials.
How do I request a consultation?
Share your town and project needs through the form. New England Slate Pros is an independent referral site; provider coverage, credentials, and availability must be confirmed. Submission does not book work.
