Your roof may be old, but you think it seems healthy since it’s not leaking.
After all, the San Gabriel Valley may get hard rains once in a while, but it doesn’t pour throughout the winter. Anyway, it’s now August and winter rains won’t hit for at least a few months.
But what you don’t know is that a sneaky thief is stealing your roof’s health.

Garvey Roofing repairs and installs every type of roof–from historic homes, to contemporary mansions, and commercial roofs
The sun is blasting your rooftop with ultraviolet rays that gradually weaken your roof. Sure, our local cities get varying amounts of direct sunshine. Pasadena and Altadena have many shady streets while Alhambra gets plenty of direct sunshine.
Intense surface temperatures dry out older shingles and weaken seams. Eventually, edges curl, surfaces crack, and the shingle’s protective granules slide down the roof and into gutters.
Older tile roofs are weakened by the heat, too.
The tiles themselves aren’t affected, but the hidden waterproof underlayment underneath becomes brittle and is eventually unable to stop the rains from leaking into your attic.
Late summer’s high heat coupled with winter winds and rain, wears down your roof.
Commercial roof materials expand under the heat during the day and contract when the weather cools at night. This results in splitting and membrane cracks.
Garvey Roofing works throughout the San Gabriel Valley and installs and repairs roofs for all seasons, using the best roofing materials for the job.
Summer heat is a major reason why roofs degrade. Then the winter rains will take advantage of weaknesses.
How Garvey Roofing Installs Roofs that Last
Healthy roofing begins with the proper foundation. Garvey Roofing lays down the right type of plywood and uses the best underlayment for the job.
The underlayment, like Therma Sheet, reflects almost all of the sun’s rays back into the atmosphere and helps prevent heat from transferring into your attic.

Both asphalt shingles and tile can be used and kept attractive for decades to come. The style that you choose depends on your tastes, budget, and your home’s location.
Thomas Garvey has made custom roofs for select clients, including making a roof for a client that looked like her childhood home back East.
Commercial buildings with low slope or flat roofs are best protected by the leading membrane roofing products available. Garvey Roofing’s team is skilled at properly laying it, ensuring that it stays flat and waterproof for decades and can work with challenges like interior drains.
Ventilation
Proper air flow in the attic, along with blown-in insulation, keeps air circulating so the attic stays as cool as possible in the summer and remains dry in the winter.

Soffits for Fire Hardening
Ask about soffits to protect the eaves and harden your structure against the possibility of fire.
