Cedar Roof Inspection Process


The only way to know if your roof needs repair or maintenance is to have your cedar roof or other type of roof inspected by us. We provide a FREE no obligation roof inspection & estimate for you.

If any work is needed after our inspection is complete, we will then present a detailed written description along with information on all products that we recommend using to preserve your roof .

Inspect all roof pipe flashings such as rubber or lead pipe boots to ensure they will not start to leak


We will inform you on how many bundles of shingles , shakes & ridge-caps that should be used to repair your roof the correct way (Quick note most cedar roof mainenetance companys do not install or replace the above mentioned flashings or vents, but we feel these are very important aspects in prolonging your roof thus should be inspected)


Locate any loose , damaged or Missing flashing around chimneys, skylights & roof pipes


We will measure the exact lineal feet of all rusted flashings & valleys (Excluding non rusting metals like copper and aluminum)


Determine the amount of decay & growth on the roof using the latest mouisture reading diagnostic equipment

Roof Repair Process


We start by replacing all missing, damaged shakes & ridge caps that are accounted for in the roof inspection process. secure all loose shakes & migrating nails.

We then refasten every ridge-cap over the entire roof , This will prevent wind damage & keep birds from nesting in the ridge-cap.

As always we replace any damaged or missing felt paper throughout the entire repair process.

In some cases we use Ice & water shield to stop or prevent a leak in certain areas such as: valleys, chimney crickets/saddles, skylights & roof pipes.

Ice & Water shield is a self adhered waterproofing membrane that is applied under the felt paper to prevent ice dams & water entry.

We always use rust resistant fasteners made specificly for cedar roofs when repairing your roof.

Only premium #1 Blue Label 100% Vertical (Edge) grain shakes, shingles are used to repair your roof (NO FLAT GRAIN SLASH GRAIN)

But before we start any of the above mentioned work we determine the safest way to complete your roofing project, thats why we only use the latest in roof climbing equipment & footwear exclusively designed for the cedar roofing professional .


Roof Flashing & Valley Caulking & Rust Prevention Process


This is a very important step in maintaining your roof because its been proven that neglected

Flashings & Valleys are more susceptible to have leaks , Thats why we always practice the following steps to ensure leaks wont develope

After a thourough inspection we refasten all loose flashing around chimneys & wall flashings.

All rusted valleys , Flashings & Roof pipes are prepped by scraping / sanding loose paint and rust.

Surface preporation is key to prevent rust from returning to all flashings.

We then apply a high grade weather resistant caulking to seal out mouisture to all metal valley peaks & break points , Counter flashings

After all caulking is complete we then apply two coats of rust preventing primer & two coats of rust preventing paint.

If your home has copper or aluminum valleys & flashings the priming/painting is not necessary as these metals do not rust or corrode

However we will inspect them the same way making sure the are tight and caulked correctly to ensure leaks will not develope .

Cedar Roof Cleaning &

Treatment Application


After all the prep work is completed, we pick up all debris from the repairs & hand scrape the organic growth from the roof

We then clean the roof using leaf blowers or compressed air (depending on the severity) to remove leaves, tree debris & organic growth.


We then apply our exclusive cedar roof treatment to your roof saturating all shakes & ridge-caps using a low pressure spray system to ensure a heavy & even application

The treatment is now locked into the fibers of the wood & the weather does the rest

Because of the cleaning action of our cedar roof treatment the moss, fungus & lichen are destroyed & will be kept away for a long time

Your shake roof will return to that silver grey color it had when it was just a few months old

The length of time to return the cedar roof to the silver grey color depends on the roofs age, condition and weather. Roof pitch is also a factor

Our exclusive cedar roof treatment is biodegradable & enviroment friendly.


It will not damage landscaping, stain your concrete, clog your gutter system and will not harm human or animal life.

We do not pressure wash cedar roofs since a pressure washer can range from 1500 to 3500 PSI which results in taking 1/8 inch up to 3/16 of an inch off the surface of the shake/shingle . Not to mention the possibility of causing a leak from loosening flashings & damaging the felt paper interlayment.

Do yourself and your roof a favor do not pressure wash it.

*Note while our treatment is not made for insect prevention we have noticed our treatment helps protects against drywood termites, carpenter ants, old house borers, powderpost beetles, wood boring beetles & silverfish...kind of a bonus to our roof cleaning & treatment
