Mike Williams Western PA Slate Roofing

Repair your roof - don't replace it!

Mike Williams Western PA Slate Roofing is dedicated to the preservation of the slate roofs of the western Pennsylvania region. Properly maintained a slate roof can last 150 years and beyond and is much more environmentally - friendly than asphalt or fiberglass shingles. Slate also adds aesthetic beauty to homes and neighborhoods because every roof is "one of kind". Often times people mistakenly replace their slate roofs when a repair would cost less than $ 1000, so before you give up on your slate roof, give us a call. If your roof is at the end of its functional life, we will not ask you to waste your money.

Review by in Pittsburgh, PA
I have a red slate roof -- a rarity, and this company knows how to address the problems that come with it. The crew were knowledgeable, courteous, and thorough. It wasn't cheap, but in this case, I believe we got the value for our money. We will definitely use them again.

Review by in Pittsburgh, PA
It may be strange to say I love my roofers but these guys were great. From Mike who did the initial inspection to Chris, Tim and Ron who did the work I was very pleased with their friendliness, professionalism, and quality. The cost was slightly above the original estimate but I was aware and approved of the addition expenses. I would recommend these guys to my friends and anyone else who needs slate work or any type of roofing work.

Project: Repair a Natural Slate Roof
We so far only had him come to inspect the roof of the house we have put an offer on, so we have yet to see how the repair will go. We have a very good impression so far, though he only looked at our roof through binoculars, but maybe that's how slate roof real estate inspections go?

Mike came on time and completed the work as soon as weather permitted. He and his crew were polite and respectful, and his original estimate was the total cost. I would definitely call him for any other roofing issue.

Seal of Approval

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.
  3. Verification of State Business Filings
    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
    We use 3rd party data sources to check the principal/owner of the business for state level civil legal judgments entered against them.
  8. Liens Search
    We use 3rd party data sources to check the principal/owner of the business for liens placed against them.
  9. Identity Verification (SSN)
    HomeAdvisor verifies the social security number(s) of the owner/principal for identity check purposes. This check applies primarily to smaller business entities.
  10. Identity Verification (Reverse Phone Lookup)
    We conduct a reverse business phone lookup to identify records matching the phone number information provided by the business.
