We had a great experience working with Precise Roofing on our roof replacement. From start to finish, the process was smooth, professional, and efficient. The quality of their work really stands out. Our new roof looks amazing, and everything was completed with great attention to detail. Joseph was especially fantastic to work with. He was very responsive, communicative, and always available to answer our questions, which made the entire process much less stressful. He kept us informed every step of the way and made sure everything stayed on schedule. We truly appreciate the team’s hard work and would highly recommend Precise Roofing to anyone looking for reliable, high quality roofing services.
Gutter repair, fast efficient and professional. Joseph was attentive and made sure to go the extra mile. I am so grateful. Thank you Precise Roofing!
Professional, courteous, and thorough. They checked that every shingle and seal was perfect. The roof feels solid, and the service far exceeded my expectations.
Our vintage home needed a roof repair that matched its classic style. They specialize in historic homes and did an amazing job. They preserved the aesthetic while enhancing the roof's functionality. Their respect for historical integrity and craftsmanship was impressive.
My roof was replaced by David, and the outcome is fantastic. I was quite impressed by his craftsmanship and attention to detail.
Contractor matched replacement shingles perfectly with our existing roof appearance. Beautiful afterward.

Tap a point on one of our own drone photos to see what we look at during the free inspection, and why it matters.

Step and counter flashing where the stone meets the shingles. The number one leak source we find on Bay Area roofs.
Six layers. Zero shortcuts.

Clean sites, magnet swept
Landscaping protected, debris hauled daily, and a magnetic sweep for nails.
Eight signs your roof needs attention
Roofs rarely fail overnight. They send warnings first. Catching them early is the difference between a repair bill and a replacement bill.

Water stains on ceilings
Brown rings mean water is already inside the assembly. The entry point is often far from the stain.
Missing or lifted shingles
Winter wind peels back aging shingles first. One missing tab lets the next storm start on the underlayment.
Granules in the gutters
Gritty gutters and bald patches mean the sun has cooked the protective surface off your shingles.
Sagging roof lines
A dip in the ridge or field points to deck or framing trouble underneath. This one should never wait.
Slipped or cracked tiles
On tile roofs the underlayment does the waterproofing. Slipped tiles expose it and it fails fast.
Ponding on a flat roof
Water sitting for more than two days finds every seam. Clogged drains turn a small roof into a pool.
Moss on the north slope
Moss lifts shingle edges and holds water against them. Common under trees in Marin and the hills.
Repairs that keep coming back
Paying for the same leak twice means the source was never found. We fix causes, not symptoms.
Four steps from first call to flyover
No sales theater. An inspection, a written number, the work done to spec, and photos from the air to prove it.
Reach out
Call, text or send the form. We ask a few questions and schedule the inspection, often for the next day.

Free drone inspection
We walk the roof and the attic, fly the drone, and show you what we found with photos. Written estimate the same day.

We do the work
Tear off, deck repair at the per sheet price you approved, underlayment and flashing the same day, then your new roof to spec.

The flyover
We fly the drone over the finished roof, send you the photos, walk the property with you and hand over the warranty.
