A roof is a connected assembly

Choosing a visible roofing product matters, but so do the less visible layers and transition details that move water and manage heat and moisture.

Questions homeowners ask

Roofing Systems FAQs

Are shingles the whole roofing system?

No. They work with the deck, underlayment, flashing, penetrations, ventilation, drainage, and edge details.

Does every home need the same ventilation approach?

No. Ventilation should be considered with the roof and attic configuration rather than treated as a universal add-on.

Can materials be selected only by color?

Color matters, but compatibility, slope, exposure, maintenance, system details, and budget also deserve consideration.
