In case the roof gets wet, the following things should be taken care of. Roofing that has gotten wet during the rainy or winter season can be covered with shingles only if allowed to dry out first fully. If the felt is still wet, it may rip apart when you start placing down the shingles. If the surface underneath your roofing is wet, you may have a threat of mold and mildew formation. It leads to the deterioration of the subsurface as well as the roofing felt.
Wrinkles and warps that form in the feet tend to generate heat pockets that destroy the shingles over time while having rips in the surface compromises the felt ability to guard the roof. As mentioned above, underlayment works to add an extra layer of protection for your roof. Yes, for a few days, you can be protected from the weather. Underlayment can be installed in the same way as shingles. We have to overlay the edges to ensure that every inch of the roof you have to protect is covered properly.
Therefore, sooner or later, you have to think about more viable options. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

The wood feels spongy and weak to the touch. The wood easily crumbles or cracks. There is a damp, musty smell.

Your roof has had a leak, ice dam , tree damage or other potential damage. Your attic has developed moisture issues. You are about to install new attic insulation or ventilation. Why is My Roof Decking Damaged? How to Replace Rotted Roof Sheathing Once your professional roofers have fixed the underlying cause of the moisture, they will need to replace all the wood affected by the dry or wet rot.
Tools and Materials Required Here are the tools and materials your roofers will need: New decking. Safety equipment. Crowbar or tool to remove shingles. Measuring tape. Roofing nails. Roofing hammer or nail gun. Other roofing material to cover the new decking. It will be impossible to know for sure how much of the roof decking has rot until your roofers can remove all the shingles above it.
However, your roofers may give you an estimate of how much wood rot there could be to help you get a sense of the scale of the repair job. If this will be a costly project, they may have options to help you finance the roof repair. Step Two: Remove the roofing. All the roofing in the affected area above the decking needs to be removed, including the shingles and underlayment. Depending on the location of the rot, your roofers may need to remove the flashing as well.
Step Three: Measure the area. Your roofers will discover the extent of the wood rot and then measure out the areas that they need to replace. Step Four: Cut out rotted wood. Your roofers will use the saw of their choice to remove the rotted wood carefully, without cutting the rafters below. Every section that is cut should extend above a rafter. That way, when your roofers place the replacement boards in, at least one rafter supports them. Step Five: Cut the replacement decking to fit.
Back on the ground, your roofers will cut out new decking material to fit the gaps. You can choose a new material as it is fine to mix plywood and OSB.
However, the new decking should be the same thickness as the old, so that the shingles will lay flat. Step Six: Position the replacement. We see the underlying plywood outlines when the sun is just shining over the roof in the morning. The builders put the roof on during rainy weather, so I suspect that is the root of the problem.
The contractor will not answer my phone calls or registered letters and our home is now 8 years old. What might be going on? Thankfully, we have no leaks.
A: It is never a good idea to install a roof over wet plywood or any type of roof sheathing. Trapped water will boil when the sun heats the roof and the shingles will then have small pits where the steam finally escapes. Installing shingles over wet decking also will void any warranty you might have from the shingle manufacturer. The thinner plywood is prone to cupping in between the rafters, but is approved by some building authorities.
