Fascia Repair

Normally the things I post here are projects that most DIY’ers have the ability to do. This is not one of those projects. This is a demonstration of what can be done in a similar situation.

Arizona is brutal to anything containing moisture. Especially exterior wood. Most homes in Arizona are of either block or wood frame with stucco exteriors. Roofing ranges from shingles to clay or concrete tiles, and in some cases closed cell foam. The trim boards at the bottom edges of the roofs are almost always wood, and are called Fascia. Recently I repaired some fascia that had been savaged by the Arizona sun and rain.

Be advised that this is not a novice repair nor is it recommended if you are on your first skil saw and have less than a couple of hundred hours of cutting time. Call a pro for this.
First, you are not on the ground.
Second, you will be cutting at eye level, in order to control your cut.
Third, removing and replacing the fascia is heavy and awkward.
You have been warned!!

Here is a photo of the damage a few years created. This is not just peeling paint and warped boards. This is dry rot. This creates an interesting problem. This is a carport with a foamed roof. The fascia is 2×12” material. Removing the fascia completely is not an option.

A foam roof’s drip edge also forms the dam for the roofing foam. So removing the drip edge to replace the fascia would entail removing about a foot of foam roofing and the drip edge to replace the entire fascia. This is not a repair you want to undertake at home. After you removed the foam, drip edge which will end up needing replacement, replacing the damaged boards, you will need to install new drip edge of the proper type and find a roofing company to foam the space you created,(the foam in a can looks like roof foam, but it is not) and re-coat the roof.

What I am doing is cutting the fascia at the bottom of the drip edge, replacing it with new material, gluing and screwing it in place, priming and painting.

The plywood outriggers are screwed to the roof joists and the arms extend beyond the fascia to act as a holder for the old fascia and as a guide for the new material. Here is a side view.

Next up is a photo of the area I am repairing. Notice that the fascia below the drip edge is in good condition, which is why this type of repair will work in this situation.

The new material is ripped to depth,(In this case I started with a 2×10 -9 1/2”actual. and ripped it down to 8 1/2”) and cut it to length. I am using PowerGrab glue on the top of the new fascia and on the faces of the roof rafters, and screwing it in place with 3” deck screws. Note: The top screw is angled up at 45 degrees to pull the new material tight to the existing fascia. Then there are an additional three screws in the field. I also used 1 5/8” deck screws through the miters to hold them tight. I used a countersink bit to preĀ  drill my holes.
Here is the result.

I used DryDex ”pink stuff’ spackle for the screw holes and a 35 year paintable latex caulking, for the edges and the gaps on the back side where the old and new material joined.

I used Glidden Gripper Primer for this. Fantastic Primer. Couple of coats of Behr Exterior Latex and it should be good for 5-10 years.
