Flashing shed roof addition.

When a shed roof ties into an existing roof the new roof could be a simple lean to that covers a deck or porch or it could be the shed roof of a substantial addition. While some skylight manufacturers include flashing in their products sometimes roofing professionals have to create it or purchase it separately. The edge of the roof has thin metal flashing that helps water drip off the roof without damaging the home or causing a leak. Each flashing job is a little bit different and depends on the type of material that the exterior of your house is made of.

If the outside edge is 8 feet high and the area being covered is 15 feet attach the shed roof addition at least 9 feet 3 inches above the level of the porch or other area being roofed or 10 feet 6. Next the sheet siding for the addition was nailed directly to the studs to quickly enclose the space. A shed roof should slope at least 1 inch per foot but 2 or 3 inches will be better. Flashing was added along that wall to keep the water out.

The new roof matched the slope of the shed roof but it tied in slightly lower on the wall to simplify the building process.
