Help With Extending Roof

[Rubicone]

Looking at making a new veranda with a cold room underneath and extending the roof to cover the area. The new veranda will run the width of the house and extend out about 4 feet. I do not know how to design the roof extension and would appreciate any help from those who have the knowledge and/or experience in this matter. See photos for a visual display (cannot seem to upload the left-side of home photo).

Ooh, that's a rough one. Looks like you'd have to use the existing gable roof at left, add framing to make the gable extend to the right and out four feet toward the street, then re-roof the whole thing. The vent at the end of the hipped roof might have to go.

What's a cold room ?

Cold Room is used for storage, little insulation and will be directly below the veranda. One is already there but will be demolished.

Thanks. Did my prescription make sense ?

The appearance would be of a large gable end, identical to the one over the living room window but running the full width of the new veranda. Because the pitch (slope) will be the same, the new gable will be fairly tall.

An alternate would be to eliminate all gables and extend the hipped roof to the front of the new porch. Construction cost might be similar, so it's a matter of taste or preference. The second solution is going to look "plainer," with a lower profile as seen from the street, and a lot less paint.

I am not familiar with all the terms regarding roofs (gable, hip), so not very clear on what it is you are proposing. As pictures are worth a 1000 words, here is a visual of what I imagine it to look like finished. Is this doable?

wow, I wouldn't do that. The dutch gable would be fine (if it was centered) but everything else is over the top.

That might be a neighbor ? If you like that appearance it is certainly doable, and no more "busy" than the present arrangement, I guess.

A gable is a vertical panel, normally triangular, that ends a two-sided pitched roof; your living room and little porch roofs exhibit gables. Your main roof, without the gabled additions, is a hip or hipped roof; all four sides have the same pitch (slope).

One difference between my two initial suggestions is that the first one has the new veranda a bit narrower than the body of the house, following the present pattern where the living room has a projecting bay that steps in from the left side of the house a foot or more. The veranda would be that much narrower than the house, on both ends.

In the hip-roof version, the veranda would presumably be the same width as the house.

The problem is how to draw this all down on a sheet of paper, specifying how it will all be done.

[SDR]

Your local architect will make quick work of that. By pointing to the house you show above, his time will be saved.

What if the option of using a gable at the front, would that involve extending the existing one or building a completely new one?

[SDR]

The contractor might elect to remove the existing roofing and finish siding (and the existing porch and its roof), then building on to the existing gable.

Is there any design picture on the Internet so I can visualize the framing that you know of?

[SDR]

This photo shows how additional framing can be added to an existing roof. Your builder may choose to do it this way. The gable framing here is typical.

Why does it look like the rafters are standing on end-points? When building on an existing gable how does one tie into that?
