Plumb

Find reviews of a roofer

Who reviews a roofer, and can you trust them?

Plumb does not review a roofer itself. We tell you which sites do, and grade each on the one thing that decides whether to believe it: how independent and evidence-based the ranking is.

GuildQuality High Scoring Confidence Crowd reviews
Grades: its verified surveys of a contractor's own customers
Real verified-customer surveys with an all-reviews-published policy, but only paying contractors get profiled and surveyed, so it is a reputation tool for members, not an independent cross-vendor ranking.

BuildZoom Medium Scoring Confidence Directory / lead-gen
Grades: its contractor scores and matches from permit data
Grades contractors mostly on hard public records (licenses, permits, BBB), but the same contractors pay BuildZoom a success fee and their on-platform activity feeds the score that drives placement, so the ranking is not arm's-length.

Angi High Scoring Confidence Directory / lead-gen
Grades: its contractor ratings and rankings
A lead-gen marketplace in a review site's clothes: the pros up top paid to be there.

4 C
Yelp High Scoring Confidence Crowd reviews
Grades: its crowd-sourced star ratings of local businesses
The star you see is not the average you think, and ad spend buys the placement above it.

5 C
Houzz High Scoring Confidence Marketplace
Grades: its reviews of local design and remodeling pros
A photo-inspiration giant and contractor directory whose review listings double as an ad product, and by its own disclosure the price a pro pays is a ranking factor for sponsored placement.

6 C
Nextdoor High Scoring Confidence Crowd reviews
Grades: its neighbor 'recommendations' and 'Faves'
Reviewers are address-verified neighbors, which is a real anti-fake-review edge, but there's no published ranking method and businesses are openly coached to solicit their own recommendations.

Expertise.com High Scoring Confidence Directory / lead-gen
Grades: its 'best [pro] in [city]' lists
A tidy 'best local pro' badge that its own contract says you can pay to wear.

8 C-
Thumbtack High Scoring Confidence Directory / lead-gen
Grades: its star-rated local-pro listings and matches
The pros you see are the ones outspending rivals on leads, not out-qualifying them.
13222
9 C-
SolarReviews High Scoring Confidence Crowd reviews
Grades: its consumer-review rankings of solar installers
Useful consumer-review hub for solar, but it earns its money selling leads to the same installers it lists, and critics call it a lead-gen site first.
12332
10 C-
Reviews.org High Scoring Confidence Editorial reviews
Grades: its phone, internet, and TV provider rankings
Carrier reviews from a site owned by a company that, by its own portfolio, is paid to market and generate leads for many of the carriers it ranks.
13222
11 C-
Porch High Scoring Confidence Directory / lead-gen
Grades: its contractor matches and ratings
A home-services lead marketplace where contractors pay for leads and, by Porch's own description, buy premium "first priority" placement -- treat its pro rankings as advertising, not an independent verdict.
13212
12 C-
Google Reviews High Scoring Confidence Crowd reviews
Grades: its star-average of user reviews on Business Profiles
Free and everywhere, impossible to buy rank in, and swimming in fake reviews with an opaque order.

Better Business Bureau High Scoring Confidence Ratings & rankings
Grades: its A+ to F business letter grades and accreditation seal
A trusted-looking letter grade that a 2010 ABC News 20/20 investigation showed a $425 payment could obtain, even for fabricated companies.
12222
14 D
Bark High Scoring Confidence Directory / lead-gen
Grades: its matches between requests and local pros
A pay-per-lead marketplace, not an impartial reviewer: by its own marketing, the paid Elite Pro tier buys top placement in the listings buyers see.
12212
15 D
HomeAdvisor High Scoring Confidence Directory / lead-gen
Grades: its contractor matches, ratings, and badges
Your details sold to several contractors at once; visibility goes to whoever pays per lead.

16 D
Care.com High Scoring Confidence Marketplace
Grades: its caregiver profiles, ratings, and reviews
A paid caregiver marketplace, not an independent reviewer: profiles carry family ratings but caregivers can pay to boost visibility, and the FTC took action in 2024 over its deceptive job and background-check claims.
