Sunlight can cause considerable damage to a commercial roof, and the amount of sunlight you have in your area has a great effect on your roof's overall longevity. The two most common types of commercial roofs are built-up roofs and single-ply membrane roofs. They both use organic materials — asphalt on a built-up roof and either EPDM or TPO on a single-ply membrane roof. Ultraviolet light will slowly break down the hydrocarbon chains in these organic materials, eventually causing them to oxidize and break apart — when damaged, you'll notice asphalt chipping or your single-ply membranes cracking.

Putting lots of thought into your bathroom is important when you're designing a custom home with a builder. Many people opt for an en-suite bathroom off the master bedroom but struggle with how to situate another bathroom for the other family members. One option is a Jack-and-Jill bathroom — a bathroom that is positioned between two bedrooms and accessible via both of them. Jack-and-Jill bathrooms are a good choice if you have two children who will need to share a bathroom.
