Roof Replacement in St. Louis, MO

All of it is installed to manufacturer spec, which is what protects the material warranty. When nailing or underlayment is shortchanged, coverage is void, and the homeowner finds out long after the crew is gone.

Layers are the first unknown. It is common to find two and occasionally three roofs on a city home, sometimes with original wood shake at the bottom of the stack. Every layer adds tear-off labor and disposal weight, and it is the single biggest reason a city estimate needs the roof actually inspected rather than measured off an aerial.

Under those layers, expect plank decking rather than sheet goods. Where planks have shrunk apart or where a previous leak rotted a run, boards get replaced or the deck gets sheathed over to give the new fasteners something continuous to bite into.

Staging is a genuine constraint. Many of these homes have no driveway, a narrow gangway to the side, and alley access at the rear. Dumpster placement, permits where the street is involved, and protecting a neighbor's property a few feet away all have to be worked out before the first shingle comes off rather than improvised on the morning.

Historic district review applies in parts of the city, and where it does it can govern material and visible appearance. That is worth establishing early, because it occasionally rules out the product a homeowner had in mind and always takes longer than people assume.

Low-slope sections are nearly universal here, over a rear addition, a porch or a kitchen. Those cannot be shingled, so most city replacements are genuinely two systems on one house, shingle on the main slopes and membrane on the low-slope areas, tied together at a transition that has to be detailed properly.

Neighbors are close enough to matter. Tarping their beds, keeping debris out of a shared gangway, and running the magnet across the sidewalk and the parking strip are not courtesies on a city job. They are part of doing the work.
