The idea is to replace it with a single solution (probably Nu-Lok) to improve looks and weatherproof the house. This would require a redesign of part of the roof (the colorbond part, about 25% of the roof) to increase the pitch of the roof. Apparently Nu-Lok can handle roof pitches as low as 5 degrees.
Would you consider involving an architect for this new roof design (which also includes replacing soffits, fascia's and all downpipes, etc.), or just work with a builder/roofer?
Thanks
