Replacing Shingles Or Shakes
1 SPLIT DAMAGED SHINGLES OR SHAKES WITH A HAMMER AND CHISEL and wiggle them from side to side to remove. The shingle directly above the one you're removing will hide the nails. Remove them by slipping a shingle puller over them or cut them flush with the surface with a hacksaw.
2 SPLIT NEW SHINGLES OR SHAKES TO FIT, ALLOWING A 1/4 -INCH-WIDE EXPANSION GAP. Starting with the lowest row, position the replacements. Nail near the top with aluminum or zinc-coated nails. When you loosely nail the top row in place, slip the top of the replacements under the row above, with the bottom edges 1/2 inch below the old shingles.
3 TAP THE SHINGLES INTO ALIGNMENT, hiding the nails in the process. Stain the new eh ingles to match the weathered color, not the original.
Replacing Damaged Board-And-Batten
1 REMOVE THE BATTENS ON EACH SIDE OF THE DAMAGED PANEL Remove the damaged panel. Replace the underlayment if necessary. Find a replacement panel that matches neighboring material.
2 CUT A REPLACEMENT BOARD TO FIT, LEAVING A 1/8-INCH GAP ON EACH SIDE BETWEEN THE NEW BOARD AND THE OLD. Prime or finish the edges and back of the new board and let it dry.
3 NAIL THE REPLACEMENT BOARD IN PLACE. Caulk the joints between the new and old boards, then reattach the battens. Prime and paint or stain to match.
Repairing vinyl and metal siding
Repairs to vinyl and aluminum siding are a bit trickier than those to wood. The replacement pieces have to match the originals exactly, and finding them sometimes proves harder than the actual repair. Your best option: Once you’ve removed the damaged panel, take it to a home center or show it to a reputable contractor, who will probably be able to identify the manufacturer. If neither can supply you with the materials you need, contact the manufacturer and ask to be put in touch with a dealer near you.
MATERIALS: Replacement siding, panel adhesive, caulk, aluminum nails, roofing cement
TOOLS: Siding removal tool, pry bar, slot cutter, hammer, tin snips, roofing knife, pliers, file, caulking gun
Patching Vinyl Siding
1 REMOVE AND INSTALL VINYL SIDING WITH THE HELP OF A SIDING REMOVAL TOOL, available at home centers. Find the top of the damaged panel and slip the tool between it and the panel above. Slide the tool along the seam, pulling out and slightly downward.
2 LIFT THE PANEL ABOVE THE DAMAGED AREA OUT OF THE WAY BUT DO NOT REMOVE IT. (The panels are flexible enough to lift away easily.) Use a pry bar to loosen and remove nails securing the damaged panel or panels. Remove the damaged panel(s).
3 INSERT THE NEW PANEL (OR PANELS) IN THE REPAIR AREA, STARTING AT THE BOTTOM. Secure panels with the same fasteners used originally. For the last panel, force the fastener in with a pry bar slipped under the lap above. Lock the panels together with a siding removal tool.
Let that vinyl breathe - Vinyl siding expands and contracts even more than wood siding. A series of nailing slots run across the top of the panel. Drive the nail into the center of the slot and let it stick out 1/8 to 1/4 inch so that the vinyl can move. Driving the nails tight will cause buckling. Avoid stretching the panel to maximum width when you nail, which will limit it's ability to contract and expand. Trimming a piece to fit removes the elongated nail holes; however, don't nail directly into the paneling, even if the trim looks as if it will cover up your work. Use a nail hole slot punch to add holes wherever you need them.
Replacing Aluminum Siding
1 CUT OUT THE DAMAGED SECTION USING A ROOFING KNIFE AND TIN SNIPS. Make the top cut about 1/4 inch from the top of the damaged piece. Avoid making cuts on the vertical seam between two pieces. Pull downward to remove the piece from the watt.
2 USING AN EXTRA PIECE OF SIDING, CUT A PATCH 11NCH LONGER THAN THE HOLE. Trim off the fastener along the top of the piece so that it will lie flat, but leave the bottom lip intact. If replacing more than one piece, trim the fastener off the top piece only. File any rough edges smooth.
3 TEST-FIT THE PATCH. If the pieces don't fit well, straighten out the S-curve along the bottom of the patch with pliers. Apply construction adhesive on the siding near the edges of the patch and around the damage. Put the patch over the repair area. Tap the bottom edge with a 2x4 scrap and a hammer to snap the piece in place. Paint to match the existing siding.
Replacing Aluminum End Caps
1 SOMETIMES DAMAGED CORNER CAPS COME OFF EASILY. If the cap is pinned tightly under the cap above, however, pry out the bottom of the damaged cap, cut along the top of the cap, and remove it.
2 LOCATE MATCHING REPLACEMENT CAPS AND THEN ATTACH THEM WITH ALUMINUM NAILS. Start at the bottom if replacing more than one cap.
3 TRIM THE NAILING TAB OFF THE TOP REPLACEMENT CAP AND THEN APPLY PANEL ADHESIVE TO THE BACK. Snap the cap over the bottom lips of joining siding courses. Seat the cap in the construction adhesive, aligning it properly.
