Adding a room to a Franklin house
On an older house a sunroom is usually a porch conversion, and matching the roofline, the siding and the proportions is what makes it look like it was always there.
The 2000s houses came with a covered patio or nothing, and the sunroom is an addition off the kitchen or the family room; the electrical panel usually has the room for it.
In higher-specification houses the sunroom is an architectural addition with a matching roof and finishes, not a kit, and it is designed and priced as one.
On a sloped lot the sunroom sits on piers or a walkout foundation, and the engineering is most of the cost; the view is usually worth it.
The ground under a sunroom decides its foundation — clay that needs footings below the movement, a slope that needs piers, a low corner that needs drainage first — and the foundation is priced before the glass.

What Franklin homeowners want from the back of the house
The recurring problem locally is the roof tie-in. A great many existing sunrooms across the region were added as a bolted-on aluminum pan roof under the existing eave, and that detail leaks — water tracks back under the shingles and rots the band joist behind it. Doing it properly means cutting into the roof and flashing the connection, which costs more at the start and is the difference between a room and a maintenance problem.
- An existing sunroom that is too hot in summer and unusable in winter
- Condensation, leaks or rot at the joint where an older sunroom meets the house
- Wanting more usable living space without the cost of a full addition
- A view or a garden the house does not connect to at all
Bolt-on roof under the eave. It is the standard cheap detail and the standard source of rot at the connection.

Condensation on Sunroom Glass in Cold Weather
The first cold mornings of fall are when a sunroom starts to sweat. A little fog that clears by ten is normal. Water pooling on the sills every morning is not.

Flooring for a Sunroom That Gets Hot and Cold
The floor in a sunroom is not the floor in the living room. UV, heat, cold and the door to the yard rule out more choices than people expect.

Sunroom Roofs: Glass, Solid or Polycarbonate
People choose a sunroom for the walls of glass and forget the roof is the surface that takes the sun. It is the single choice that decides the temperature inside.
