STOCK OPTION AGREEMENT

        A Stock Option (the "Option") granted by Beacon Roofing Supply, Inc., a
Delaware corporation (the "Company"), to the employee named in the attached
Option letter (the "Optionee"), for common stock, par value $.01 per share (the
"Common Stock"), of the Company shall be subject to the following terms and
conditions:

        1.    Stock Option Grant.    Subject to the provisions set forth herein
and the terms and conditions of the Beacon Roofing Supply, Inc. 2004 Stock Plan
(the "Plan"), a copy of which is attached hereto and the terms of which are
hereby incorporated by reference, and in consideration of the agreements of the
Optionee herein provided, the Company hereby grants to the Optionee an Option to
purchase from the Company the number of shares of Common Stock, at the purchase
price per share, and on the schedule, set forth in the attached Option letter.
Any Incentive Stock Option is intended to be an incentive stock option within
the meaning of Section 422A of the Internal Revenue Code of 1986.

        2.    Acceptance by Optionee.    The exercise of the Option is
conditioned upon its acceptance by the Optionee in the space provided therefor
at the end of the attached Option letter and the return of an executed copy of
such Option letter to the Secretary of the Company no later than 60 days after
the Date of Grant set forth therein or, if later, 30 days after the Optionee
receives this Agreement.

        3.    Exercise of Option.    Written notice of an election to exercise
any portion of the Option shall be given by the Optionee, or his personal
representative in the event of the Optionee's death, in accordance with
procedures established by the Compensation Committee of the Board of Directors
of the Company (the "Committee") as in effect at the time of such exercise.

        At the time of exercise of the Option, payment of the purchase price for
the shares of Common Stock with respect to which the Option is exercised must be
made by one or more of the following methods: (i) in cash, or (ii) in cash
received from a broker-dealer to whom the Optionee has submitted an exercise
notice and irrevocable instructions to deliver the purchase price to the Company
from the proceeds of the sale of shares subject to the Option.

        If applicable, an amount sufficient to satisfy all minimum Federal,
state and local withholding tax requirements prior to delivery of any
certificate for shares of Common Stock must also accompany the exercise. Payment
of such taxes can be made by a method specified above, and/or by directing the
Company to withhold such number of shares of Common Stock otherwise issuable
upon exercise of the Option with a fair market value equal to the amount of tax
to be withheld.

        4.    Exercise Upon Termination of Employment.    If the Optionee's
employment with the Company and all affiliates terminates for any reason other
than death, disability or retirement, the then vested portion of the Option
shall continue to be exercisable until the earlier of the 90th day after the
date of the Optionee's termination or the date the Option expires by its terms.

        In the event of the Optionee's death, disability or retirement during
employment with the Company or any affiliate, the outstanding portion of the
Option shall become fully vested on such date and shall continue to be
exercisable until the earlier of the first anniversary of the date of the
Optionee's death, disability or retirement or the date the Option expires by its
terms. For this purpose (i) "disability" means (as determined by the Committee
in its sole discretion) the inability of the Optionee to engage in any
substantial gainful activity by reason of any medically determinable physical or
mental impairment which is expected to result in death or disability or which
has lasted or can be expected to last for a continuous period of not less than
12 months, and (ii) "retirement" means the Optionee's termination from
employment with the Company and all affiliates without cause (as determined by
the Committee in its sole discretion) when the Optionee is 65 or older. (Full
vesting of

the Optionee during his lifetime and 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 Option 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 Option, other than in
accordance with its terms, shall be void and of no effect.

shall be exercised in whole, this Agreement shall be surrendered to the Company
for cancellation. In the event this Option shall be exercised in part or a
change in the number of designation of the shares of Common Stock shall be made,
this Agreement shall be delivered by the Optionee to the Company for the purpose
of making appropriate notation thereon, or of otherwise reflecting, in such
manner as the Company shall determine, the change in the number or designation
of such shares.

        7.    Administration.    The Option shall be exercised in accordance
with such administrative regulations as the Committee shall from time to time
adopt.
