Full Roof Replacement on a Black Diamond Bungalow

A complete tear-off and new shingle roof on a bungalow on the edge of Black Diamond, in Diamond Valley. The old roof first, then the install step by step, in photos our crew took on the job.

The original shingles had worn thin, with granules washing off and tabs no longer sitting flat. On a home this exposed to foothills wind, that is when leaks and blow-offs start.

How the new roof went on

Step 1

Tear-off to the deck

The old shingles came off right down to the original plank deck, so our crew could see and check the wood before anything new went on.

Step 2

New underlayment

Fresh underlayment was rolled over the deck. It is the second line of defence under the shingles if wind-driven rain or snowmelt ever gets past them.

Step 3

Shingles stepped across

New shingles went on in staggered rows across the underlayment, so no seam lines up with the one below it.

Step 4

Nailed from the eave up

Each course was nailed in from the eave up the slope, with every shingle fastened to hold against foothills wind.

Step 5

New vents flashed in

New roof vents were set into the shingles with their own flashing, keeping the attic breathing and the roof watertight around every opening.

The project

The home. A single-storey bungalow on a large lot at the edge of Black Diamond, with lawn, mature trees and open fields around it. Homes out here take the full force of foothills wind and big temperature swings, which is hard on an aging roof.

The work. A full roof replacement: everything off down to the original plank deck, new underlayment over the whole roof, new architectural shingles and new roof vents.

Why a full tear-off. Stripping to the deck is the only way to see the wood and start the new roof from a sound base. Laying new shingles over old ones hides problems and shortens the life of the new roof.
