How Do I Transition From A Shingle Roof To A Metal Roof?

The change from shingle to a metal roof can be difficult and should only be attempted with the assistance of an experienced metal roof contractor. Here are some of the basic phases of the procedure.

1. Think about the Materials

Deciding which material best matches your property before building the roof is critical. Many metals are available on the market, some of which are rather costly. Copper, aluminum, steel, zinc, corrugated roof panels, and tin are some of the available metal possibilities.

2. Measure the Roof Size

Your home’s roof should be measured using measuring instruments. Determine the roof’s length and breadth, as well as the vertical gap to the bottom of the same rafter. The total square footage of the area may be calculated by multiplying the area by the slope.

3. Cut out Old Roof and Install Edging

Remove the old shingles and hammer down all the nails, beginning at the top. After removing the shingles, examine the roof for any damage.

If your budget allows it, consider installing roofing insulation. After removing the previous roof, attach the edging and corner pieces so that the panels may be joined together.

4. Install Metal Panels

The first panel should be placed such that it overlaps the edge by 1/2 to 3/4 inches. Install all of the screws along the ribs now. After installing the screws, run the silicone sealant along the bed to form a seal. Continue to add the remaining panels until the roof is completely covered.

5. Install Roof Ventilation

After attaching the metal panels, measure and label the ventilation unit. Mark the contour of the needed roof cuts, then cut it with a professional saw. When you’re finished, you’ll be able to look inside the attic. Seal the edges with sealant before inserting the vent.

6. Install the Flashing

Protect yourself with safety equipment when installing a metal roof. Flashing is a basic metal trim that aids in the waterproofing of your roof. The metal trim goes over the joints where two sections meet and aids in directing water to the roof’s base.

How Do You Attach A Metal Roof To A Shingle Roof?

There are few ways to attach a metal roof to a shingle roof:

1. Nail or screw the underlayment and battens into the shingles.

Lay out the underlayment felt flat across the previous roof if the shingles are in good condition. Secure the felt to the plywood beneath the shingles using a nail gun or hammer.

Then, nail horizontal, parallel rows of 2 by 2 in (5.1 by 5.1 cm) or 1 by 2 in (2.5 by 5.1 cm) boards along the ceiling.

2. Lay out metal panels and secure them to the battens.

You might need help with this. Carry the metal sheets to the roof and fasten them with screws to the battens or subroof. Because these sheets are usually rather large and cumbersome, it may take some time to align the seams of each sheet to make the space symmetrical.

3. Install closure strips over the gaps and add the flashing.

Cover each seam where the two sheets meet with rubber or foam closing strips after the metal sheeting is in place.

These will prevent water from entering your roof. Then, flash the roof by covering the roof’s edges with a drip edge and the peak with a ridge cap. Screw the flashing into the edging and/or battens beneath the roof.

-Use a rubber grommet to cover each visible screw or nail to prevent water from entering the microscopic spaces between the fasteners and the roof.

-In terms of roofing projects, metal roofing is quite simple and quick to install. Laying metal sheets close is easier than laying individual shingles or securing rubber slate.
