Covered Porches FAQs

Will the new porch roof match my existing roofline?
Yes. The new porch roof is framed to match your existing pitch, finished with materials that coordinate with your shingles, and flashed where the new roof meets the existing roof and wall. We walk the tie-in point with you before any framing goes up.
Two to three weeks on site once construction begins. The added time over an open deck comes from framing the roof, installing the roofing material, and finishing the ceiling underneath.
What is the price range for a covered porch?
Covered porches sit at the higher end of our project range, with screen porches and porch-plus-deck combinations going higher. We do not take on porch projects under 200 sq. ft. You will get a specific number after the in-home consultation.
Yes. A covered porch can be built open and upgraded later with screen panels or Sunspace window enclosures without rebuilding the structure. If you think you may add them down the road, mention it during the design phase so we can frame the openings at the right dimensions.
