"Very high pressure sales. For your own sake have cameras rolling during sales pitch. Don’t let them make you believe that the installation is done by Erie. Totally subcontracted. Talked us into choosing them even though they were 7k higher than other roofers with the promise of higher quality service that didn’t happen, job site was a mess had to inspect gutters they were not cleaned. They came back out cleaned said it was done got back up on ladder gutters still full and found damaged siding on back of chimney. After filling with BBB repairs and cleanup were done just not worth the higher price. Price started at $26 a square for metal and $15. For fiberglass after 4 hours of sales it came down to $21 metal and $10.5 a square foot fiberglass. I surely have buyers remorse hopefully this review helps someone in their decision. Also suggest reading this [*** Link removed ***] prior to reading all the A+ ratings on BBB Also make sure proper permits were pulled they did not pull one till after the install when I questioned it.

Insulation questions, answered by experts

Even though spray foam insulation typically comes at a higher price point than other insulation types, the benefits make up for the investment. Some benefits of spray foam insulation include:

  • Improved air quality, as this type of insulation helps minimize indoor allergens

  • Easy installation 

  • Lifespan of 80 to 100 years.

  • Added home strength, protecting it from humidity and wind.

  • Additional soundproofing

  • Energy bill savings

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.

When installing metal siding, a high-quality house wrap is considered the best protection against condensation and moisture infiltration. House wraps can increase a home's efficiency significantly. However, a house wrap is not a replacement for a vapor barrier because it can be permeable when moist air passes through siding. This is why it's essential to follow manufacturer instructions for insulating siding when installing new siding.

On average, attic insulation costs $1 to $3 per square foot, so for a 1,800-square-foot attic, you’d pay $1,800 to $5,400, including materials and labor. The cost can vary depending on what type of insulation you use, how many insulation layers you need, and whether you need to remove existing insulation first.

DIY is possible for basic rolls or batts, but professional installation ensures even coverage and efficiency.
