Building Homes or Extensions/smells after new roof



Our single story house just got a new roof - Certainteed shingles part of the house -  and IB roofing system  (garage and kitchen).  Throughout the process there has been a heavy glue smell in the house.  Is it normal?  We aired it out, thought it was gone, turned on our central air system and the glue smell is back REALLY STRONG. What happened?  What do we do?  Is it toxic?  

Also, IB system on flat roof (looks like PVC) has some bubbles.  Can this affect the longevity of this roof system?   

Thanks,  Gabriel

Hello, Gabe.

It's frustrating in situations like this, answering important questions online, because I can't smell what you're smelling, and can't see the severity of the bubbles.

I'm very concerned if there are VOC's (volatile organic compounds) in the glue that are toxic. You and your family shouldn't be breathing them, and they should have dissipated by now (although you didn't say how long ago the new roof was applied). With summer weather, you should be able to keep your windows open to help ventilate your home; if necessary, also use fans blowing out to increase the air flow.

The bubbles you mention can also present a longevity problem, depending on where they are and how big the bubbles are. If you trust the roofing company that applied the roofing, contact them and tell them about the problems (smell and bubbles). Any reliable, ethical company should take care of their clients -- not just a pat on the head -- provide real answers for you, and be willing to rectify the situation for no additional charge. You have a distinct advantage, because you can tell the world in social media how you've been treated by the roofing company (whether bad or good). Angie's List is an excellent way to report companies who provide products and services, to help others become informed consumers.

If you feel like the roofing company is not willing to help you, you can contact the National Roofing Contractors Association, If you're unhappy with the installation and their unwillingness to help you, you might be able to register a complaint with them. Like all professional organizations, they want to know if anyone installing roofs is giving everyone a bad reputation.

There's also a lot of information about your IB roofing online, if you want to search. I just typed "ib roofing" in Google, and got 1,300,000 results. Bing search resulted in 965,000 results. I also searched for "ib roofing glue." The first article listed talked about voc-free glue for ib roofing:

So, here are my recommendations:

1. Do some preliminary research online, to become better informed about the specific product that was used for your home (including glue options);
2. Contact the roofing company and ask for their help; if they don't help you,
3. Contact the NRCA (website, and phone call, if necessary).

Good luck! I hope that you get the best results with both of your roofing problems.
