LOW-SLOPE ROOFS

Roof life in Monrovia is decided by exposure more than brand, and the grade means water moves fast and finds every lazy flashing detail. From the shop it is a 15-mile run northeast to Monrovia, so emergencies get a same-day answer.
Crews rotate through Duarte, Bradbury and Arcadia, so the drive is routine.
We would rather be on your roof in September than during the first atmospheric river. Nothing is booked until you have photos, a scope and a written price.
Most homes take two to four days once material lands.
A roof is a system. The membrane or shingle gets the attention, but the underlayment, the fasteners, the edge metal and the ventilation decide whether it reaches its warranty.
Price follows the roof, not a rate card: access, pitch, material, how many layers come off and what the deck looks like underneath. We measure in person, show you photos and put the number in writing before anything is booked.
Cheap work shows up at the details: a flashing sealed instead of replaced, a vent reused because it was quicker, decking covered because nobody wanted the conversation. Those are the roofs we get called back to in two winters.
Ventilation gets looked at while the roof is open; most Monrovia attics run hotter than they should.
What a roof faces in Monrovia is specific, not generic: steep lots and open exposure age the windward side years ahead of the rest. From the shop it is a 15-mile run northeast to Monrovia, so emergencies get a same-day answer.
We are often working Duarte, Bradbury and Arcadia in the same week, which keeps costs sensible.
We would rather find the problem in the dry months and fix it on a schedule. We will tell you if the roof has five years left, because that is also useful to know.
Before we quote we check the deck, the ventilation, the flashings and the drainage. Three of those four are invisible from the ground, and all four decide how long the roof lasts.
We do not use subcontract crews we have never met. The people on your Monrovia roof are the people we train, and they carry our workers' compensation.
Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Monrovia tightens fast, and emergency work costs more than planned work.
Everything below is the same crew, same city, same free inspection.

CLEAR ANSWERS. LOCAL EXPERTISE.
MONROVIA, CA TORCH DOWN ROOFING
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.
For most flat and low-slope roofs in Monrovia, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
Most single-family roofs in Monrovia are done in two to four days once materials are on site. Larger or steeper roofs, or jobs with deck repairs, run longer and we say so up front.
You get the manufacturer warranty on the materials and ours on the workmanship, both in writing. The paperwork is registered for you and transfers if you sell.
Yes, licensed, bonded and insured, with workers' compensation on every crew. Certificates are available before work starts.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
We carry the permits and insurance for hot work, run a fire watch and keep extinguishers on the roof. Where open flame is not appropriate we quote a cold-applied or coating system instead.
A modified bitumen base sheet torched to the deck or cover board, with a white Polyfresko cap sheet over it. The white surface reflects heat instead of holding it.
Monrovia sits next to these, and we cover all of them from the same trucks:
We cover Duarte, Bradbury, Arcadia, Sierra Madre and Temple City from the same yard as Monrovia. Ask about the city you are actually in — we probably work it.
