After Your New Roof Installation: Common Questions

What is a Proper Roof Installation and how do you know if you got one? 


A proper roof installation will make your home look fantastic and give your home protection for decades to come. To some homeowners, this sounds like a fantasy after living through a nightmare with their roofing company. 


We are going to assume you did your homework and hired a top roofing professional and got a solid job form them. 


Elements that go into a top new roof installation


  •        Start with a clean roof deck
  •        Use top roofing materials
  •        Use ice & water barrier in valleys and around penetrations
  •        Make sure to remove all nails and debris from the roof’s deck 
  •        Lots more


These are just the beginnings of a well-done roofing job and we will also assume most, or all of these things were done on your new roofing project. 


OK, you have your new roof! Now what? Many homeowners will now look hard at their new roof and will see a few things that will concern them like shingles not lying flat and humps in their valleys and around their chimney. 


Let me go over a short list of things that initially worry homeowners after a new roof installation. Shingles not lying flat is probably the most common question and very easy to explain. All asphalt shingles have a thermal sealant strip on the back of the shingle. When you lay one shingle on top of another in a roofing job the top shingle adheres to the one beneath it. This is called thermal seal and even in the hot southern climate of say Louisiana it takes a few days to a few weeks for this to completely seal and is nothing to worry about. 


Another common question is my valleys seem raised up, why? A good roofing company is going to add ice & water barrier to not only your valleys but around all penetrations like plumbing pipe jacks, chimneys, and exhaust vents. The addition of this watertight barrier is thick and will give your shingles a raised appearance in these areas. 


One more common question I have seen over the years, I see what looks like sumps and humps in my roof. The technical name for this is deck deflection. According to CertainTeed Corporation which is one of the largest shingle manufacturers in the United States this is due to improper roof ventilation. This will not cause any problems with your roofing system; the only thing will be a little unsightly if it is really bad. 


These are the most common after roof installation questions. The main thing you want to do is ask questions and be informed. I have always said a well-informed client is a happy client. Do your research and hire well and you can have true peace of mind.
