Roofing
10 miles from downtown of Strawberry, CA
T G says: „Let me open this up by saying we wish we had completed this job 8 years ago, right when we bought the house, a 1955 quasi Eichler with a low slope, uninsulated tar and gravel roof and no AC. We’re located in a sunny and very warm North Bay valley where 90F+ summer days would result in unbearable roof heat built up and transfer while on chilly winter days we couldn’t keep the house warm enough.
Having obtained several quotes and consulted with Gus, we chose Alex and his team and the result turned out to the best investment and upgrade we have made to the house so far. The install took 5 days and the attention to detail was evident. Alex has decades worth of SPF spray on experience, is a consummate craftsman and walked us through the process, explaining every step in detail, and his entire team were punctual and professional.
Having now lived under this new roof for the last 12 months, here are the findings: besides serving as a very sturdy brace for the entire structure, it has proven to have the insulating properties as advertised. The house no longer creaks loudly as it did when it heated up or when buffeted by wind gust, and the morning following the roof completion – early February with temps in the 30s - the interior no longer had the typical cold spots where we experienced them before. We supplement central heat with a high efficiency EPA rated Danish wood stove and it now only takes a load or two of wood for the heat to spread and remain within our 1500sq feet structure whereas multiple continuous burns were required before.
Summer performance is equally impressive. Our interior stays about 10-15 degrees cooler than it did with the tar and gravel as all the heat is reflected and not transferred in. Here are the numbers: on a 105F day it was 89F inside pre foam, and a mid 90s day out would result in mid 80s inside by late afternoon.
With the foam on, it was 78 inside by the end of a 102F day and it stays in mid 70s with 90F heat out. I imagine that the numbers would likely be better if we did not have 11 skylights perforating the roof and allowing for passive heating.
Attached are pics showing temp. readings at the ceiling in our living room and in our unfinished garage in summer ’22 and with the foam on in ‘23.
If you’re contemplating a spray on roof, I can’t recommend Alex and his family business highly enough ...“ Show more
