What makes a Colonial or Federal roof harder to work on?
Steep pitches, several gables and chimneys that rise through the middle of the roof are common on houses of this age, as a general pattern. Each of those is a place where a roofer has to work carefully. Steep roofs are slower to work on, and chimneys need flashing that is cut and fitted around the brick, not simply stuck on.
Valleys on older houses can drain slowly, and leaves and debris collect in them. A leak that shows up on a ceiling below a valley is often a flashing or a clogged valley problem, and the shingles beside it are fine. A roofer can tell the difference on an inspection, which is why a short repair visit is sometimes the better first step than a full quote for a new roof.
The pages on chimney flashing repair and roof repair describe what is checked at each joint.
Does the National Register listing change what I can do to my roof?
The East Greenwich Historic District has been on the National Register since 1974, but a National Register listing and a local review requirement are not the same thing. What binds a homeowner is whether the town has locally designated the area and has a commission that reviews exterior work. For Newport, which has such a commission, a locally designated district needs a Certificate of Appropriateness before exterior work, roof replacement included.
For East Greenwich the safe advice is the one the research gives: check with the town before changing roofing materials on a historic property. Ask before you order, not after the shingles are on the truck. A swap from a slate look to ordinary asphalt is exactly the kind of change that can draw a question.
Our guide to historic district roofing in Newport and Pawtuxet explains how the process works in places that have it, and slate, cedar and historic roofing covers the materials.
What should a quote on an old East Greenwich house mention?
A written quote for a house built in the 1700s or early 1800s should say what happens to the existing roof layers, how the deck will be checked for rot, and how chimneys and valleys will be flashed. If it only gives a total, ask for those details in writing.
Ask also who handles the permit and any town review. Your roofer should be able to tell you in one sentence which office the application goes to.
Which East Greenwich roof problems can wait, and which cannot?
A single missing shingle on a sound deck can often be dealt with at a roofer's next free slot, while an active drip into a ceiling should be reported promptly and caught with a bucket. Put a plastic sheet over what the water might reach, and keep away from a ceiling that is sagging or bulging. We cannot tell you whether a roof is safe, and no one can from a phone call.
On a house this old, ask the roofer to explain what they see in terms you can follow: where the water is entering, what material is there now and what the choices are. A few photographs from the ground, taken before the call, help the conversation. Keep them with your quote so that the work can be compared with what was proposed.
