What causes a Sagging Roof?

Even if you have done all you can to keep your roof in good condition over the years, it can still deteriorate and droop. Sometimes your roof may not be that old but has been subject to a lot of storms in the last year. It is important to understand why your roof is sagging before you can repair it. These are the top causes of roof sagging:

It’s too heavy – When was your last roof inspection? Your roof may droop if there are structural problems. Roofs are meant to support a maximum weight load. Anything more can cause sagging. Your roof could sag if it has inadequate storm bracing or undersized rafters.

Water damage – Roofs are meant to drain water efficiently. However, heavy rainstorms or flooding can cause roof damage. A damaged gutter system or shingles that are not properly installed can cause water to pool and cause damage.

Other causes – A sagging roof can also be caused by age, poor quality materials, or a sinking foundation. To determine the root cause of your sagging roof contact Restoration Roofing TX to arrange a consultation and roof repair in Fort Worth Texas.

HOW TO FIX SAGGING ROOF TRUSSES AND RAFTERS

You will need to repair sagging roof trusses and rafters in some cases. These steps will ensure that your roof truss or rafter is properly fixed if this is what you are dealing with.

To get your truss or rafter back in shape, you will need an “L” channel made of steel.
Each side of the L should have four holes.
Use a chisel to remove any broken wood pieces (broken scraps).
Mount the steel channel “L” onto the rafter.
Use washers or bolts to fasten the end of your channel to the rafter/truss.
When the end of the piece is in place, move it into its new position.
The gap between the steel channel and the rafter/truss should be measured. Next, choose bolts 1.5-2 times the gap.
Turn the bolts at the bottom and tighten them. Next, tighten the bolt closest to the break until it is 1/4 inch from the channel.
The back bolt should be tightened until it is close to the steel channel. Then, tighten your front bolt until it is 1/4 inch from the channel.
Continue tightening the bolts at the front and back until the truss or rafter is in line with the channel.
Install bolts in the remaining holes and tighten them.
You might consider adding additional support to the area.

FIXING THE ROOF DECKING

We recommend that you hire a professional to fix any damage to the roof decking. You can, however, create a temporary solution using the steps below.

Measure the damaged area between your roof beams or rafters and cut a piece of 1/2″ plywood to cover it.
Attach a 1″ piece of styrofoam to your plywood. It might be worse if you drive nails into it.
Place the plywood and styrofoam, upside down, against the roof decking.
Push the plywood up until it touches the underside of the roof decking.
You can keep the plywood in place with a piece of lumbar strapping until you have a roofing specialist fix it.
