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.
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 San Mateo you are
Add your neighborhood, for example Baywood, Hayward Park, and Bay Meadows, 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
Best time to book custom sheet metal flashing & chimney caps
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 San Mateo, 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.
