Vegetation such as moss growth on a roof can attribute to more than just an unsightly presentation. Think of it as a sponge embedded within the spaces between shingles of which acts as an absorbent. Over time, this moisture can eventually seep into the wood decking below, thus resulting in wood rot. Further issues caused are the buckling of shingles as well as restricted water shedding.
The tip of the day is to assure your roof is clear of tree branches of which restricts drying, thus subjecting the roof to vegetation growth.
Why to adequately ventilate and insulate the crawlspace of an elevated home? Here’s why. In the south, we live in a virtual sauna for a good part of the year. When our interior air temperature is 70 degrees, contrasted with an exterior air temperature of 95 degrees – condensation will occur if the crawlspace area is not well-ventilated or insulated.
In this video taken within the crawlspace of a house on piers, interior carpet acts as an insulator, thus protecting the wood subfloor below. You can clearly see moisture damage on the portion of the subflooring where carpet is not installed. One good option would be to insulate the bottom of the subfloor with rigid foam insulation as well as assure you have adequate airflow throughout the crawlspace.
This is what water damage to roof decking looks like. It could be the result of a plethora of things - aged shingles, wind damage, lack of attic ventilation accelerating the life of roofing material, etc. In this particular case, it appeared to be a combination of poor installation and likely lack of adequate attic ventilation.
