What shapes a custom sheet metal flashing & chimney caps job

These are the things that make one job different from another. Mention them in your notes so each pro can scope your job properly.

Chimney size and shape
A wide stack, an offset chimney or one with several flues needs a larger or more complex cap or flashing.
Roof pitch and height
Steep and tall roofs call for more safety setup and slow the work.
Metal gauge and material
Copper, stainless, galvanized steel and aluminum are cut, bent and joined in different ways.
Seams, soldering and sealant
Soldered seams and folded joints take more shop time than riveted or sealed ones.
Roofing and masonry condition
New flashing needs sound roofing to lap over and sound mortar to anchor into.
Where in Gilroy the job is
Gilroy homeowners appreciate straightforward, honest work at fair prices. No Bay Area markup, no attitude — just solid handyman work delivered on time by independent providers. Tell the pro your neighborhood or ZIP code so they know the age and style of the home.

Choosing the metal

The metal sets how long the piece lasts, how it looks and what it can touch safely. Your pro can recommend one for your roof and weather. Tap an option to compare, then add your pick to your job notes.

What is not part of custom sheet metal flashing & chimney caps

Knowing where the line is keeps the visit on track and keeps you safe. When a job belongs to a specialist, NorTech tells you before you book.

  • Any job where labor and materials together reach $1,000 or more. Larger flashing and roofing scopes go to a licensed contractor, flagged before booking.
  • Reroofing, tear-off of shingles or tile and roof deck repair. Those are a roofing contractor.
  • Rebuilding chimney bricks, repointing large areas or relining a flue. That is a mason or chimney contractor.
  • Interior water damage, drywall, insulation and mold cleanup after a leak. Those have their own services.
  • Gas appliance venting, flue sizing and relining. Gas venting is licensed trade work.
  • Structural framing repairs to a rotted chase or roof deck.

Before you book custom sheet metal flashing & chimney caps

Quick things that save a trip. Tick them off as you go; none of it is required to book.

0/7
Let’s get you readyTap a card when you have done it.

Photograph the leak and the metal

Take pictures of the chimney base, the cap and any stains on the ceiling inside. Include a wide shot of the roof so the pro can judge access and the roofing around it before the visit.

Note when it leaks

Water that shows up in every rain points to different trouble than water that shows only in wind-driven rain or during a thaw. Write down the weather when you see the stain and the room it appears in.

Check the attic around the chimney

If you can reach the attic safely, look at the wood beside the chimney for dark stains, rust on nails or wet insulation. Do not step off the joists.

Count the flues and measure the top

A wide stack with two or three flues needs one large cap or separate caps. Note the number of flues and, if you can see them, whether they are clay tile or metal.

Ask about metal compatibility

Ask the pro what metal touches what on your roof. Matching metals and fasteners avoids corrosion at joints, and a good pro can explain why they chose one metal over another.

Plan for access

Clear driveway space for a ladder or lift, move patio furniture and tell the pro about pets and gates. Roof work needs dry weather, so keep your schedule flexible for the install visit.

Say where in Gilroy you are

Add your neighborhood, for example Eagle Ridge, Downtown Gilroy, and Glen Loma Ranch, or your ZIP code to your notes. Pros choose the neighborhoods they cover, and it tells them how far they have to travel.

How where you live changes custom sheet metal flashing & chimney caps

Add your ZIP in the booking card at the top to see weather alerts and the season for your area.

The condition of your chimney decides how flashing is set

Counterflashing on a masonry chimney is usually set into a groove cut in the mortar joint, so soft, crumbling joints must be repointed first or the metal will not hold. Framed chimney chases wear a different system, with siding or stucco overlapping the flashing. Old chimneys can lean, bulge or sit out of square, which is why a template is made from your actual stack instead of a catalog part. Tell your pro the material and what you can see.

Fill in the blanks first. The note goes to the pro you choose.

Best time to book custom sheet metal flashing & chimney caps

Spring Mar to MaySummer Jun to AugFall Sep to Nov

Metal and sealant install best on a dry roof in moderate temperatures. Freezing weather makes sealant fail to cure and roofs icy, and a long dry stretch lets the pro test the work. Book fabrication ahead of the rainy or snowy season so the piece is ready. In Gilroy, the dry season from late spring to fall is the easiest time for outside work, and the fall calendar fills before the first big rain.
