Check the roof before you clean it
A cedar roof with a split piece, a leak, or loose wood needs a real check first. This check should look at the wood and the layers under it. Gray color alone does not mean the roof failed. Tell the roofer what you saw and where. Ask them to show proof of parts that need work.
Keep cleaning, repair, and full replacement as three separate choices. Do not let a cleaning sale replace a real roof check. Use the condition record below to write down what you see from the ground. Then take your notes to a roofer who knows cedar roofs.
Find out which cedar type is on your roof
Shake and shingle are not the same thing. The Cedar Shake & Shingle Bureau lists handsplit shakes, resawn shakes, and tapersawn shakes. So the word shake can mean more than one look. Know the exact type. Do this before you order a matching piece.
Ask the roofer to write down the product type, size, thickness, and row layout. Share any old invoices or labels you still have. A new piece can look close in the yard but still not match your roof. Keep this step apart from deciding how many pieces to replace.

Write down what you can see in photos
From a safe spot, look for missing pieces, lifted edges, dark debris, and stains inside the house. Take one wide photo first. Take a closer photo only if it is safe. Write the date and roof side on each photo. A photo can show a problem spot. But it cannot show the full wood condition underneath.
The USDA wood-roof guide talks about weathering and moisture problems in wood roofs. It says color is not the only thing to check. Ask your inspector three things: what is just surface change, what is real damage, and what is still unknown.
Color is one observation, not a roof verdict
| What is seen | What to ask | What needs inspection |
|---|---|---|
| Gray surface | What is normal weathering here? | Wood condition |
| Missing or split piece | Can this area be repaired? | Match and adjacent pieces |
| Repeat leak | Which layer or joint is involved? | Hidden condition and flashing |
| Old finish | What was applied? | Product compatibility |
Make matching wood part of the repair plan
Ask the roofer to name the new cedar wood, its grade, and where it comes from. Ask how it will fit next to the rows already on your roof. Does your roof have a special edge or ridge? If so, ask how that part gets fixed. Do not assume a normal repair covers it.
New wood can look different from older wood at first. Talk about this before work starts. Do not expect every repair to fully disappear. If keeping the same look matters to you, ask to see a sample first. The goal is a repair that fits your roof, with the choice written down clearly.
Ask how the roof will stay dry
Cedar roofs need to dry out well to last. The USDA guide talks about leaving space under wood roofing. This space lets air dry the wood. But one setup does not fit every roof. Ask what support and underlayment your roof has now. Ask what the new wood needs.
Changing attic airflow is its own separate question. PNNL explains that vented and unvented attics work in different ways. Adding a roof vent without checking the whole attic is not a full fix. Tell the roofer about insulation changes, attic moisture, or exhaust fans.

Be careful with cleaning products and coatings
A clean roof is not the same as a repaired roof. Ask anyone offering to clean your roof what product they use, what it fixes, and how they will protect nearby materials. Have the wood checked for damage before you approve any cleaning.
The USDA guide warns against coatings that trap moisture inside wood roofs. Do not assume a product made for a fence or wall is safe for a roof. Ask for written proof the product works with your roof and any past treatment. Do not trust promises that a product can add years back to your roof.
Match the size of the repair to the proof
A small repair should list the exact spot and the pieces needed. It should also list nearby areas to check. A bigger repair plan should explain why the problem goes beyond that one spot. Ask for photos and a scope map. Do not accept a whole-roof claim based only on age or color.
Our tool sorts your notes into questions about wood, matching, roof layers, and past treatment. It cannot tell you if the wood has rotted. If you mark something unknown, it stays on your list to check. Use the result to ask for a clear repair plan.
Keep good records after the repair is done
Ask for photos of each repaired spot, a description of the new wood, and any care steps for that wood. Write down which cleaners or coatings were used, and when. These notes help the next roofer avoid guessing what is already on your roof.
Before work starts, agree on how the crew will reach the roof, handle debris, and protect good roof areas. The USDA guide warns that old shakes and shingles can crack under foot traffic. Do not climb up to check a piece or pull off moss yourself. A clear cedar repair request can start with your roof history and safe ground-level photos.
Your questions, answered
Does a gray cedar roof need to be replaced?
Color alone does not tell you that. Ask about the wood's strength, any damaged pieces, the roof layers, and signs of leaks. A good report explains what the inspector found, instead of treating gray color as proof the roof failed.
Are all cedar shakes split on the face?
No. The Cedar Shake & Shingle Bureau lists both split-face shakes and tapersawn shakes. Find out which one is on your roof before you order repair pieces. Just asking for cedar may leave out key size and style details.
Can a coating fix split or missing wood?
No. A surface coating cannot replace missing wood, and it does not tell you what repair is needed. Have the damaged spots checked first. If someone suggests a coating, ask for written proof it fits your roof and its past treatment.
What should I include in my cedar repair request?
Say where the problem is and what kind of problem it is. Mention any past repairs and any product records you have. Say if you want to keep the same look. Leave unknown details blank so the roofer can check them.
