What to know about roofs on Princeton's older homes

Princeton has homes from almost every era, from 1700s houses in the historic districts to large homes on wooded lots, and many have slate, cedar or copper that can be repaired rather than replaced. Tall trees are the other big factor: Hurricane Sandy in 2012 and the October 2011 snowstorm brought down limbs across town, cracking slate and crushing gutters.

Roofs worth doing carefully

Wooded lots across Princeton mean shade, leaf buildup, and moss on north-facing slopes. Older homes in the central historic areas often have slate roofs that can be repaired rather than replaced, along with box gutters built into the roof edge.

Slate repair vs. replacement

A good slate roof can last a long time. Often only broken slates and flashing need attention.

Built-in box gutters

Many older homes have gutters built into the roof edge. When their lining fails, water gets into the walls and cornice.

Leaves and moss

Heavy tree cover keeps roofs wet. We clean, treat and add gutter protection where it helps.

Common questions

My Princeton home is in a historic district. Can I still replace the roof?

Usually, yes, but visible changes may need Historic Preservation Commission review first. That can affect material and color choices. We will look at your roof, tell you what likely needs approval, and help prepare what the commission asks for.

Can you help with a storm damage claim?

We inspect, photograph and document the damage, and we can meet your adjuster. Whether the claim is approved is up to your insurer.

Do you go over the old roof or tear it off?

We tear off every layer down to the decking. That is the only way to find rotted wood and give you a roof that lasts.

What shingles do you install?

We are an Owens Corning Preferred Contractor, so most of our roofs are Owens Corning architectural shingles. Premium lines are available too.
