When does a roofers job become another tradesmans job?

These are a few basic questions about when roofing work overlaps with other types of work.

Sometimes a roofline that meets an exterior wall can have flashing that could be nailed to the wall behind cedar shingles. Removing that old flashing and installing new flashing may have to involve some removal of the cedar shingles. When might you choose to recommend to the homeowner to find someone who specifically does siding to properly repair the siding after you install new flashing? Or, if you have the skills to do the siding repairs yourself, would you upcharge in such a case? Is it common for roofers to do their own siding work when removing troublesome flashing?

Similarly, what if a chimney needs all new flashing when installing a new roof? Would you call in a mason who specifically does chimney work? Or are most roofers skilled in installing brand new lead flashing and working it into the bricks with new mortar?

Removing/replacing siding is part of roofing.

Dealing with masonry chimneys is part of roofing.

Cedar shakes & shingles are part of roofing.

A well rounded roofing company will have people that can deal with all of the things you mentioned, In my case I do it.

If this is a salesman subcontractor situation it is likely that neither is an actual roofing company so they wouldn’t be expected to know how to deal with flashing/siding.

In the salesman subcontractor scenario the work that is not shingling would be subbed out to those qualified or meet the bid so to speak, or more likely just doesn’t get done.


Axiom is correct. A good roof crew will have a variety of trade skills in order to deal with the wide variety of situations they’re presented with. Problem is, far too many roof crews don’t even have adequate roofing skills, good luck expecting them to have carpentry skills.


Depends on contractor ,if he pays for time ,some roofers will get it done per book but most likely not enough to justify,if it’s only $1 per ’ dont expect grinded staircase counterflashing with mortar.at most u get hemmed straight replica with few mortar nails to hold it in place and caulk over.which is the case in 95% of current market roofs.it works,looks semi aesthetic and easy to bend up on the spot,why change.

Outstanding answer! There is only one added benefit to you, your company and the client…have connections with other trades that are part of the building envelope.
