Our story
From adjuster to roofer
A roof problem rarely announces itself politely: a stain on the ceiling, shingles in the yard, a drip you hear at night. Summit Line was set up to take that call and give you clear answers, not a sales pitch. We are based in Lakewood, next to the Colfax lumber yard, and we work across Denver and the surrounding area.
- Photos firstWe photograph what we find from the attic and the deck, so you can see it before you decide.
- Signature on changesIf the scope changes mid-job, we stop and get your signature before continuing.
- Materials that fitWe choose shingles and membranes by slope, drainage and climate, not by what is on promotion.
What we do
Roofing services in Lakewood and Denver

Roof inspection
We check the roof from the deck and from inside the attic, because most hail damage is not visible from the ground. You get a photo report and a clear picture of what needs doing, free.

Roof replacement
Tear-off, decking repair, underlayment and architectural shingles.
$9,800

Storm and hail damage repair
Repair and documentation for your insurance claim. An insurer usually needs dated photos and a written scope before approving the work, and we prepare both.

Leak repair
Flashing, vents and valleys, found and sealed. A leak seen on a ceiling can start many feet away, so we trace the water along the deck before we seal anything.

Flat and commercial roofing
TPO and modified bitumen for low-slope roofs. On a flat roof the membrane matters more than the brand, so the material follows the slope and the drainage.
$6,500

Gutters and ventilation
Seamless gutters, ridge vents and attic airflow. Poor airflow cooks shingles from underneath and shortens their life, so ventilation is part of the roof, not an extra.

What clients say after the crew leaves

Hail took out half our roof. Sam documented everything with photos, met the adjuster on site, and the claim was approved on the first try.
RRachel T.
The crew had the old roof off and the new one on in two days, and they ran a magnet over the yard for nails. Not one in the driveway.
MMike D.
Three quotes, and theirs was the only one that showed me the rotten decking in photos before I signed. Price never moved after that.
