## The honest read

Cornerstone Contractors describes itself on its website as a full service roofing contractor centrally located in Rhode Island, doing residential and commercial roofing from repairs to installs. The company says it has been in business 30 years.

A 2018 customer with roof damage from storms and age said the crew worked 13 hours to get the roof done in 1 day. A 2018 customer with a small leak above a bay window said they were squeezed in before the next storm and the issue was fixed quickly. A 2023 customer said their house was sided in just a few days. A 2013 customer said the old roof needed 2 layers stripped and new sub roofing put on under it.

A 2023 customer said William answered their many questions and brought shingle samples before the contract was signed, and that the job was done in about 3/4 of a day at a reasonable price. That 2023 customer also said they were charged more than quoted for a zinc strip, and had to reach out by phone, email and text multiple times for the final receipt and warranty information.

A 2024 customer said black tar marks had to be cleaned off the driveway side of the house, where the debris trailer was placed. That 2024 customer said they told Ron they were withholding $360 from the final payment because his carpenter had done a very poor job replacing the front corner roof soffit. A 2014 customer said a new patch was put over an existing patch, and the roof leaked in three or four different areas the next time it rained. A 2013 customer who bought a $159 inspection deal said no electrical inspection was ever done and the promised quote never came.

**Strengths:**
- One-day roof job — a 2018 customer said the crew worked 13 hours
- Shingle samples shown — a 2023 customer said William brought samples before signing
- A quick siding job — a 2023 customer said the house was sided in days

**Concerns:**
- A zinc strip charge — a 2023 customer was charged more than quoted
- A soffit replacement — a 2024 customer withheld $360 over the carpenter's work
- A patched leak — a 2014 customer said it leaked in several areas after
- An inspection deal — a 2013 customer said no electrical inspection was done
