Good afternoon,

Help, the roofers are here as we speak!!!   In roofing best practices, what quality/grade of pine lumber should be used when replacing damaged roof deck boards? 

Our insurance company has authorized roof replacement as a result of damage from a recent hail storm.  The roof deck of our home (60 year old building) is 1 x 8 inch pine.  We specified that the roofer must replace like material with like but did not specify what GRADE of pine lumber should be used.

Can anyone help us?  We want to make sure that the roofing materials are good quality.

Thank you kindly! 

May be a Lil Late in Response But MAKE SURE that they Match Thickness in spaced decking, AND MAKE SURE THE SPACED DECKING IS UP TO COUNTY CODE, As the Codes surely will have changed. Check with the County To make sure. Hope this helps....AND BTW A medium grade Pine is in Order as Spaced Decking replacement.

Husker it isnt that it REQUIRES it, it is that there are ALOT OF HOMES, Like this one that HAS IT! Thats all Im saying has nothing to do with WOOD SHAKES.

It could be more complicated than that. Is this a "common materials" policy? If so, the company may choose to limit the repair estimate to common repair materials such as CDX plywood in the appropriate thickness. Is the 1X8 a toungue and groove configuration that extends out over an open eve? If so, the insurance company should at least put back the matching product, (config & grade) over the exposed eve. UNLESS the entire surrounding eve is being replaced, which is doubtful in a hail event. But if it is entirely damaged, or previously dryrotted to the point of being a "nailable surface" issue, they could insist on common grade material and only estimate the put back as CDX ply. That, all being if, and only if, the policy has the "common materials" language. I've run into this many times on State Farm policies.
Not many straight & easy answers in this biz are there!?!?!

My original response had everything to do with whether it was wood shakes, because I could not understand first of all why any entire roof deck would need to be replaced with 1x8's due to a hail storm unless there were shakes over the top of spaced board (1x8) decking. (don't get ahead now, I go back to this later).  Now then, Earthwindfire gave a good reason...with open eves & the 1x8's painted underneath.  That makes good reason.  But still, tell me why anyone now days puts 1x8 T&G  planks on the roof.  That's why I suggested it being so much easier to use 5/8 to 3/4 plywood, which provides the fully nailable surface for the most common  roofing materials.  I further qualified by stating that if shakes are required by your neighborhood covenant (HOA), then there are more modern methods that eliminate the need for spaced board decking...thus eliminating the need to find 1x8.  Show me a roof with 1x8 planking that needs to be replaced after a hail storm, and I'll show you a dagwood sandwich of 4 layers of asphalt/comp shingles over an old layer of cedar shakes with spotted rotten boards beneath.   Then, a crown molding was installed on the gables to cover up the extra layers & 2 or 3 courses of drip edge.

The end result after a loss, in the absence of neighborhood covenants (which are going by the wayside steadily), is that CDX plywood will be installed with architectural or metal shake look-a-likes over the top.  The carrier will owe for a nailable surface in most areas, if the spaced board decking is compromised...good for the insured!  But if it's rotted T&G, how did the adjuster in this case give full allowance?   The questions were posed to the original poster, but we don't know what kind of roof they originally had or are going back with.  These were the thoughts behind my prior posts.
