Why you may need to replace your Roof Decking?

Roof Decking Issues in Colorado Springs CO

Roof Decking Issues

When replacing the roofing for your home or commercial building, roof decking just might be an additional cost.

A hidden issue that may arise during roof replacement is damaged or undersized decking. If you’ve ever walked on your roof and it feels “mushy” or “bouncy”, you probably have a damaged area or 3/8” plywood under-surface. There is no way to tell until the existing shingles and under-surface have been removed.

Changes in local building codes may mean upgrading your roof decking

Years ago, 3/8” plywood was acceptable. It was used extensively because of the lower cost versus ½” or 5/8”. You are allowed to re-roof over the 3/8”, but if you replace all the decking, you have to upgrade to a minimum ½” thickness.

Every roof requires a solid foundation

Not upgrading can be linked to the old adage about building castles in the sand. You’re installing a new product over a weak substrate. The mushiness and bounce will still be there. Even though the shingles are installed correctly, the nails won’t have the holding power they would with a thicker material. This could lead to blow off and leaks.

It is important when replacing your roof to make sure you have a solid sub-material or roof decking below your brand new roof. Our roofing crews and inspectors can give you more information regarding your roof decking when you have a free roof inspection from 7 Summits.

Roof Warranties May be Affected

The last issue is whether the shingle manufacturer will issue the warranty implied for your particular shingle selection. Decking can be an additional cost but it will help add to the overall lifetime of the shingle and warranty period.
