Estimating Additions with Roof Saddle

NOTE-- We retired the BidMagic construction estimating software in 2001. It has been replaced by Goldenseal construction estimating software.

We still include this BidMagic estimating software manual as a convenience for users of our older program. Many features are similar, in Goldenseal estimating.

Roof Saddles

The BidMagic construction estimating software computes roof areas that will cover all floor areas being worked on. It does not include the extra roofing or roof framing needed for roof 'saddles' over the existing building.

You'll need to add the extra area over the existing building to the roof area on the Roof Dimensions card, and the roof framing area on the Structural Dimensions card.

There may also be additional work you'll need to add to the bid. Check for extra framing and flashing details at the junctions of the new and old roofs, extra costs due to temporary roof covers while the roofing is off, additional siding beneath shed roof 'saddles', and structural reinforcement of existing framing or trusses.
