How to Pick a Good Roofer

Winnipeg Roofer

Finding the best Winnipeg roofer in your region could be made simple, if you can follow some of the simple guidelines in this article. You may search in the local business directory, search engines, or the social media. You can also get the referrals from your friends and relatives who have had prior experience with the roofers. Regardless of the source of data, you need to evaluate certain specific parameters which will help you pick a good roofer.

The best suggested methods are direct interaction with the roofer and his existing clients in your local region. You have to ensure the immediate availability of the roofer and his team on emergency call in the post installation period. An established company with license, insurance, and trained staffs can be reliable due to their experience and the local presence for the past years/decades.

Roofer Assessment

The local roofer website provider gives you insights into their quality, reliability, and safety parameters. Quality is a measurable value which depends on the materials, workforce and the methods of installation.

Material Selection

A reputed roofer provides the material specifications in his website clearly. Technical details about the asphalt, metal, membranes, cants, base flashings, joints, roof decks, curbs, rails and supporting elements give you the idea about their durability and criteria. Look for ASTM and EPA certifications in the material specifications. The certified materials may cost relatively more, but they are feasible and durable for many decades. The maintenance costs are also lower. Non-standard materials may be cheaper in price. But their durability and safety factors are very low. The cost of frequent repairs and replacements will be much higher than the initial investment you make on higher quality materials. Make sure the roofer provides the material warranty sheets along with the quote.


Reliability of a roofer depends on his industry experience and the client base. Expertise in handling the vast range of asphalt and metal roofing types for residential and commercial constructions is a plus point.


Safety is the primary criterion for the selection of a good roofer. He should have the working license from the state and the local government authorities. Licensing establishes the trustworthiness the conformance to the legal, structural and environmental standards and regulations. Choosing a roofer with no license can be risky for you as a homeowner.

Insurance is the other safety factor which you should consider carefully. General liability coverage for the damages and the employee safety insurance can protect you from having to pay for the roofers’ faults during the installation time. The roofer shall also specify the home owner’s payables for the insurance in the quote. It is a legal requirement which he must follow with no exceptions.

A good roofer shall provide all the safety gears and equipment to the employees during the installation procedures. They help in protecting the employees from injuries and the structures from damages. Make sure the roofer follows the OSHA guidelines to keep you out of any legal problems.

Installation Methods

The ASTM-D3462 standards for the asphalt shingles roofing specifies the material and methods to be used to ensure durable structures. The performance parameters are related to the roof assembly, structural profile, ply system, insulation, concrete/wooden deck, and the base sheet. The roofer should provide the complete specifications about the dimension, material types, assembly methods, and the performance details about the structure.


A good roofer provides you with the detailed drawing of the proposed roofing design and construction. Draining edges, gutters, snow shedding structures, parapet wall, supported decks, termination bars, and divider curbs, etc. The design about the laying of the shingles shall contain details about the type of adhesives, nails, fasteners, and the other structural elements.

Site Inspection

The roofer shall inspect the installation site and analyze the existing roof (for replacements) and the supporting structures. If the installation is new, he shall consider the parameters related to the impact of the dynamic and static load on the roofing materials as the first criterion. The other criteria could be the climatic conditions (average maximum and minimum temperature, heat and humidity level, rain and stormy weather, wind and hail speed, snowfall, etc).

After the analysis, he prepares the detailed document consisting of the drawing, material and part specifications, proposed construction method, safety and durability factors, etc. This document shall conform to all the aspects of ASTM, and the local government’s legal guidelines accurately. .

Quote Submission

A good roofer shall give you the quote with all the above specified details with the material cost, service charges, VAT (wherever applicable), insurance deductibles, and the related costs. The tolerance for any unexpected additions or deductions will be within +/- 5% to +/- 10% range which he shall specify. If the quote contains any hidden costs, it could mean large scale escalation in the costs at the project end.

It is better to sit with the roofer and discuss about the costing after you get 3 to 4 similar quotes from the other service providers. One-to-ne interaction will help you understand the quality and customer commitment levels of the roofer better than any other method.

Clientele Interaction

You can have one-to-one interaction with the existing clients of the roofer. Ask him for the local referrals with whom you can speak over phone or have a face-to-face meeting whenever possible. You can also request the clients for permission to visit their home if they agree. It is a way of making new friends and getting to know the service quality of the roofer. It is also the best method of assessing the roofer directly without any options for confusions.

Online Client Testimonials

If client interaction is not possible, you can read the online client testimonials on the social media and the review pages. They give you the basic information about the service quality and the reliability of the roofer to a considerable extent.  It would be better, if you can engage with the clients in the social media through chat. It helps in filtering out the self-promotional testimonials posted by the roofer.
