What we look at on the roof
On asphalt shingle roofs, we look for curling, cracking, missing pieces, bare spots where the grit has worn off, and nails that are popping up.
On slate roofs, we look for slipped, cracked, or missing slates, and for slates that have gone soft or flaky. We also look for old tar patches. Tar on slate often hides a problem.
On cedar roofs, we look for splits, rot, moss, and curled shakes. On metal roofs, we look at seams, fasteners, rust, and the edges.
Flashing, chimneys, and roof openings
Most leaks start where the roof meets something else. We check the metal flashing at chimneys, walls, dormers, and skylights.
We look at pipe boots, the rubber or metal collars around plumbing vents. These crack in the sun and are a very common leak point.
We look at the chimney cap and the top of the chimney too, since water can enter there and show up lower down. If the bricks or mortar need a mason, we will tell you.
Valleys and gutters
A valley is where two roof slopes meet and make a channel. Valleys carry a lot of water, so worn metal or shingles there leak fast.
We also look at gutters and downspouts. When gutters clog, water can back up under the roof edge and rot the wood.
The attic: where leaks leave clues
If you let us in the attic, we look for dark stains on the wood, wet insulation, rusty nails, and spots of daylight.
We also check airflow. Vents at the eaves and near the ridge help the roof stay dry and last longer. A hot, damp attic can wear out a roof early and cause mold.
Leak clues inside your home
Show us any stains, bubbling paint, or damp spots. Tell us when they show up: every rain, only in wind-driven rain, or only when snow melts.
These clues help find the cause. Water often travels before it drips, so the stain may be a few feet from the real opening.
Storm damage checks
After a storm, we look for lifted or creased shingles, missing pieces, dents in metal, cracked slate, and damage from fallen limbs.
If you plan to call your insurance company, dated photos and notes help. Our insurance claims guide explains how to get ready.
What you get after the inspection
You get photos and a short list in plain words. Each item is marked as fine, watch it, fix soon, or fix now.
If something needs work, you get choices. That may be a small repair, a section repair, or a plan for a new roof. You decide. Nothing is done without your OK.
