new roof on home purchase

I am all about Certainteed.Every shingle manufacture has quirks and they all share class action suits,material failures,discoloration and shading issues.

What you should really be thinking about is the manufacture that stands behind its product.And that is for the most part all of them.

I prefer Certainteed because they guaranty the product (H,W,L) dimensions to exceed/under no more than 1/8".Most others are 1/4" or more.In smaller sections you can adjust a shingle that has a different exposure measurement from the previous bundle.

All my roofs are installed with chalk lines ensuring an extremely straight roof.Everything is installed by a specific measurement.Tape measures don't lie,,,people do.I like a shingle that maintains a specific measurement.And IMHO that is Certainteed.

6 and 7 nail patterns should be used in high velocity wind regions.And those fasteners should be installed within each material manufactures recommended nail lines.

You could buy top of the line shingles but if your contractor of choice doesn't install them according to manufacture specifications then its money wasted.When I was contracting in Florida Atlas Pinnacle was the dominate shingle.

It really boils down to who is installing them.Having accreditations from God,NRCA,Master Elite,Shingle Master and whatever else you can grab means nothing unless you apply those techniques to every installation.I know several of these masters who do crap work but use these accreditations as a means of gaining customer confidence.Word of mouth is what you should be using to find a qualified contractor.

Someone who has first hand knowledge of business practices,ethics and integrity of a roofing contractor is priceless.Ethics and integrity are things you cannot pick up in a manual. :thumbsup:

Ask around within your church,neighborhood,friends,relatives and other associates to gain first hand account of their experience with a roofing contractor they have done business with and were satisfied with.
