Broken sealant

Some insurance companies still dont want to pay for broken sealant caused by wind damage on shingle roofs. They talk about roofers rippin people off! These homeowners pay premium for years and now cant sell their house because they need a texas windstorm>>>

Kevin is right on, period.

If im looking for loose tabs im checking the butt joints as they are always the place that is unsealed on a roof if anything thing is loose,first to go.>>>

Is this the kevin with the shake roof been gone so long I hardly knew ye? Yo!>>>

I humbley dis-agree with all of your assesments. I do not believe the wind either knows or cares if a tab is at the seam or not. If this was simply wind it would have lifted tabs in the middle, and opposite end of the shingle as well. I believe what you are dealing with here is expansion and contraction of the shingle, possibly due to poor ventilation or in a vaulted area, (and I think HAAG would back me up on this). Asphalt shingles will expand as much as 1.5% in length, you cant stretch the shingle, so it pops loose at the logical spot...the end. Manufactures have to balance between a too aggressive seal, and a not aggressive enough seal. If it didn't let loose, it would rip. If there isn't too much dust or dirt, and the seal strip is still intact it should reseal. If it doesn't, it is neither an ins propblem, nor manufacturers problem....it's a homewoners problem because they are responsible for the proper ventilation. Unless the roofer that originally installed the roof has a good relationship with the manufacturer, the owner will be on his own. Now, lets sit back watch you all call me a moron.>>>

Bump>>>

Most adjusters are not very knowledgeable about the roofs installation process.>>>

Most that are still on are still held by the nails just the sealant..tar strip is unsealed. Sometimes the nails pull through but the shingle is still there. Ya there are jobs where its poor install but the roof is protecting the ins company interest.>>>

most unadhered shingles are only at the seam and always on the same side....directional wind...ie...with 3 tab its every 3'. usually only at the seam. thanks dougger. do elk shingles count since they are now gaf?>>>

There has to be transference present to prove the wind caused the shingles to loose it's seal. In other words there must be proof that the shingles were once sealed.

If you go up on the roof and can lift every tab and there's been no transference the r>>>

The insurance company hired engineers that said they are unsealed because of improper installation not because of wind. Most of the companies are payin it but a couple wont.>>>

Thats exactly right Rg. Debris comes in the shape of many things like dirt, granuals, leaves etc.>>>

You must be talking about transference?>>>

Here is a 20 year shingle with wind lift. >>>
