How this differs from a reroof
A roof replacement puts new shingles on a structure that is already there. A new roof build starts earlier: the rafters or trusses, the sheathing, the fascia and the overhangs all have to be built before a single shingle goes on. It is the roof part of a bigger project, and the part that decides whether the addition looks like it was always there or looks bolted on.
That covers room additions, attached and detached garages, covered porches, and the roof on a gut-and-rebuild. Because we also do the siding, gutters and windows, the new section can be closed in and finished by one crew.
The tie-in is where new roofs leak
The weak spot on almost every addition is the seam where the new roof meets the old one. Get the pitch wrong and the two roofs never line up. Skip the step flashing where the new roof runs into an existing wall and water gets behind the siding. Leave a flat pocket where two slopes meet and it holds snow and water.
We plan the roof line with the rest of the house in mind: matching the existing pitch where the design allows, carrying the valleys through cleanly, and flashing every place the new roof touches a wall or chimney. Where the new roof meets the old shingles, we work the new courses into the old ones so the transition sheds water like one roof.
Built to Indiana's roof rules
- Design loads. Marion and Johnson counties are listed at a 115 mph design wind speed and a 20 psf ground snow load in Indiana's residential code table. The framing and sheathing are sized for that.
- Drip edge. The 2020 Indiana Residential Code requires drip edge along the eaves and rakes of shingle roofs, so it goes on every new edge we build.
- Ice barrier. Along the eaves and up the rakes, wherever the shingle maker's instructions call for it.
- Permits. A new roof is new construction, not a reroof, so the exemptions that cover some shingle jobs do not apply. Indianapolis, Beech Grove, Greenwood, Franklin and Johnson County each run their own permit office, and we work with the one that covers your address.
Matching the old roof. We install Owens Corning and CertainTeed shingles. If your existing roof is near the end of its life, it is often worth reroofing the whole house while the addition goes on, so everything matches and wears out together. We will price it both ways.
New roof questions
Yes. We can pick up at the sheathing, or at the shingles, as long as the structure underneath is sound. We look at it before we quote so there are no surprises.
We match the shingle style and color as closely as the market allows. Older roofs fade, so a brand-new shingle can read a little darker for a while. If an exact match is not possible we tell you before we order.
Yes, attached and detached. A detached garage gets its own gutters and downspouts too, which we can add in the same job.
Yes. Framing, house wrap, siding, windows, doors, gutters and the roof can all come from our crew, so you are not coordinating three contractors and waiting on each one to finish before the next can start. See home renovation for how we run a whole project.
