RESTRICTED STOCK UNIT AWARD AGREEMENT

(Time-based Vesting)

Grant Information:

Vesting Schedule:

A Restricted Stock Unit (RSU) Award (the “Award”) granted by Beacon Roofing Supply, Inc., a Delaware corporation (the “Company”), to the employee named above (the “Grantee”), relating to the common stock, par value $.01 per share (the “Common Stock”), of the Company, shall be subject to the following terms and conditions and the provisions of the Beacon Roofing Supply, Inc. Second Amended and Restated 2014 Stock Plan (“Plan”), a copy of which is attached hereto and the terms of which are hereby incorporated by reference:

The receipt of the Award is conditioned upon its acceptance by the Grantee no later than 30 days from the date the Agreement was delivered, provided however, if the Grantee shall fail to accept this Award by the due date, the Grantee’s Award shall be deemed accepted by the Grantee unless the Grantee has notified the Company in writing prior to the due date that he or she declines to accept the Award.

The Company hereby grants to the Grantee the Award of RSUs, as set forth above. An RSU is the right, subject to the terms and conditions of the Plan and this Agreement, to receive a distribution of a share of Common Stock for each RSU as described in Section 6 of this Agreement.

The Company shall maintain an account (“RSU Account”) on its books in the name of the Grantee which shall reflect the number of RSUs awarded to the Grantee and any dividend equivalents paid to the Grantee as described in Section 4.

Upon the payment of any dividends on Common Stock occurring during the period preceding the date the RSUs are settled in Common Stock and distributed to the Grantee as described in Section 6, the Company shall credit the Grantee’s RSU Account with an amount equal in value to the dividends that the Grantee would have received had the Grantee been the actual owner of the

number of shares of Common Stock represented by the RSUs in the Grantee’s RSU Account on that date. Such amounts shall be paid to the Grantee in cash at the time and to the extent the RSUs are distributed to the Grantee. Any dividend equivalents relating to RSUs that are forfeited shall also be forfeited.

The foregoing provisions of this Section 5 shall be subject to the provisions of any written employment security agreement or severance agreement that has been or may be executed by the Grantee and the Company, and the provisions in such employment security agreement or severance agreement concerning the lapse of restrictions of an Award in connection with the Grantee’s termination of employment shall supersede any inconsistent or contrary provision of this Section 5.

If a Grantee becomes vested in this Award (or portion thereof) in accordance with Section 5, the Company shall distribute to the Grantee, or the Grantee’s personal representative, beneficiary or estate, as applicable, a number of shares of Common Stock equal to the number of vested RSUs subject to the Award. Such shares shall be delivered within 30 days following a Vesting Date.

Except as described in Section 5(b) and Section 9, the then unvested portion of the Grantee’s Award shall be forfeited to the Company if the Grantee does not remain in continuous employment with the Company or its affiliates until the applicable Vesting Date.

The Grantee shall pay to the Company an amount sufficient to satisfy all minimum Federal, state and local withholding tax requirements prior to the delivery of any certificate for shares. Payment of such taxes may be made by one or more of the following methods: (a) in cash, (b) in cash received from a broker-dealer to whom the Grantee has submitted irrevocable instructions to deliver the amount of tax to the Company from the proceeds of the sale of shares subject to the Award, (c) by directing the Company to withhold a number of shares otherwise issuable pursuant to the Award with a Fair Market Value equal to the tax required to be withheld, (d) by delivery to the Company of other Common Stock owned by the Grantee that is acceptable to the Company, valued at its Fair Market Value on the date of payment, or (e) by certifying to ownership by attestation of such previously owned Common Stock.

(a) In the event of a Change in Control, as defined in the Plan, unless the Award is continued or assumed by a public company in an equitable manner, the RSU shall become fully vested immediately prior to the Change in Control as if the time vesting criterion set forth in Section 5(a) had been met. The Award shall settle in accordance with Section 6.

(b) If the Award is continued or assumed by a public company in an equitable manner, then the vesting of the Award shall be contingent only upon the Grantee’s employment through the applicable Vesting Date(s) unless there is a Qualifying Termination within one year following the Change in Control. If a Qualifying Termination occurs within one year following the Change in Control, the Award shall become fully vested immediately and be settled in accordance with Section 6.

(c) For purposes of this Section 9: (1) “Qualifying Termination” means the termination of a Grantee’s employment (a) by the employer for any reason other than Cause; or (b) by a Grantee who was an officer of the Company immediately prior to the Change in Control for Good Reason; (2) “Cause” means (unless otherwise expressly provided in the Grantee’s employment agreement) the termination of the Grantee’s employment following the occurrence of any one or more of the following: (a) the Grantee’s conviction of, or plea of guilty or nolo contendere to, a felony; (b) the Grantee’s willful and continual failure to substantially perform the Grantee’s duties after written notification; (c) the Grantee’s willful engagement in conduct that is materially injurious to the employer, monetarily or otherwise; (d) the Grantee’s commission of an act of gross misconduct in connection with the performance of the Grantee’s duties; or (e) the Grantee’s material breach of any employment, confidentiality, or other similar agreement with the employer that, if capable of cure, remains uncured 10 days after written notice thereof; (3) “Good Reason” means, without the Grantee’s consent, (a) a material reduction in the position, duties, or responsibilities of the Grantee from those in effect immediately prior to such change; (b) a reduction in the Grantee’s base salary; (c) a relocation of the Grantee’s primary work location to a distance of more than 50 miles from its location as of immediately prior to such change; or (d) a material breach by the Grantee’s employer of any employment agreement between such employer and the Grantee provided, however, in all cases, a Grantee must give the Company written notice of the circumstances giving rise to the Good Reason event and thirty (30) days to cure such circumstance.

The Grantee shall not be entitled to any of the rights of a stockholder of the Company with respect to the Award, including the right to vote and to receive dividends and other distributions, until and to the extent the Award is settled in shares of Common Stock.

The Award may not be transferred other than by will or the applicable laws of descent or distribution or pursuant to a qualified domestic relations order. The Award shall not otherwise be assigned, transferred, or pledged for any purpose whatsoever and is not subject, in whole or in part, to attachment, execution or levy of any kind. Any attempted assignment, transfer, pledge, or encumbrance of the Award, other than in accordance with its terms, shall be void and of no effect.

Delivery of shares pursuant to Section 6 will be by book-entry credit to an account in the Grantee’s name established by the Company with the Company’s transfer agent; provided that the Company shall, upon written request from the Grantee (or the Grantee’s estate or personal representative, as the case may be), issue certificates in the name of the Grantee (or the Grantee’s estate or personal representative) representing such shares.

The Grantee acknowledges and agrees that the Award shall be subject to the Company’s Incentive Compensation Recoupment Policy as in effect from time to time.

The Award shall be administered in accordance with such regulations as the Committee shall from time to time adopt.

This Agreement, and the Award, shall be construed, administered and governed in all respects under and by the laws of the State of Delaware.
